    Implantable Pulse Generators (IPG) ISW

    Brief statement: Medtronic IPG

    Indications

    Implantable Pulse Generators (IPGs) are indicated for rate adaptive pacing in patients who may benefit from increased pacing rates concurrent with increases in activity and increases in activity. Pacemakers are also indicated for dual chamber and atrial tracking modes in patients who may benefit from maintenance of AV synchrony. Dual chamber modes are specifically indicated for treatment of conduction disorders that require restoration of both rate and AV synchrony, which include various degrees of AV block to maintain the atrial contribution to cardiac output and VVI intolerance (e.g., pacemaker syndrome) in the presence of persistent sinus rhythm. See device manuals for the accepted patient conditions warranting chronic cardiac pacing. Antitachycardia pacing (ATP) is indicated for termination of atrial tachyarrythmias in patients with one or more of the above pacing indications.

    MRI SureScan IPGs: A complete SureScan pacing system is required for use in the MR environment and includes a Medtronic SureScan device connected to Medtronic SureScan Leads.

    Contraindications

    IPGs are contraindicated for concomitant implant with another bradycardia device and concomitant implant with an implantable cardioverter defibrillator. There are no known contraindications for the use of pacing as a therapeutic modality to control heart rate. The patient's age and medical condition, however, may dictate the particular pacing system, mode of operation, and implant procedure used by the physician. Rate-responsive modes may be contraindicated in those patients who cannot tolerate pacing rates above the programmed Lower Rate. Dual chamber sequential pacing is contraindicated in patients with chronic or persistent supraventricular tachycardias, including atrial fibrillation or flutter. Asynchronous pacing is contraindicated in the presence (or likelihood) of competition between paced and intrinsic rhythms. Single chamber atrial pacing is contraindicated in patients with an AV conduction disturbance. Antitachycardia pacing (ATP) therapy is contraindicated in patients with an accessory antegrade pathway. Medtronic Kappa™ 400 Series pacemakers are contraindicated for use with epicardial leads and with abdominal implantation.

    Warnings and precautions

    Changes in a patient's disease and/or medications may alter the efficacy of the device's programmed parameters. Patients should avoid sources of magnetic and electromagnetic radiation to avoid possible underdetection, inappropriate sensing and/or therapy delivery, tissue damage, induction of an arrhythmia, device electrical reset or device damage. Do not place transthoracic defibrillation paddles directly over the device.

    MRI SureScan IPGs only: No lead extenders, lead adaptors or abandoned leads present; no broken leads or leads with intermittent electrical contact as confirmed by lead impedance history; the device must be operating within the projected service life, and the system must be implanted in the left or right pectoral region.  For pacemaker-dependent patients, it is not recommended to perform an MRI scan if the right ventricular (RV) lead pacing capture threshold is greater than 2.0 V at 0.4 ms.  Patients whose device will be programmed to an asynchronous pacing mode when MRI SureScan is on must have no diaphragmatic stimulation at a pacing output of 5.0 V and at a pulse width of 1.0 ms.  It is not recommended to perform MRI scans during the lead maturation period (approximately 6 weeks).  Pace polarity parameters are set to Bipolar for programming MRI SureScan to On (Advisa MRI only); or a SureScan pacing system is implanted with a lead impedance value of ≥ 200 Ω and ≤ 1500 Ω.  Revo MRI patients must have pacing capture thresholds of ≤ 2.0 V at a pulse width of 0.4 ms and a SureScan pacing system that has been implanted for a minimum of 6 weeks.

    Potential complications

    Potential complications include, but are not limited to, rejection phenomena, erosion through the skin, muscle or nerve stimulation, oversensing, failure to detect and/or terminate arrhythmia episodes, and surgical complications such as hematoma, infection, inflammation, and thrombosis.

    MRI SureScan IPGs: SureScan pacing systems have been designed to minimize potential complications in the MRI environment. Potential MRI complications include, but are not limited to, lead electrode heating and tissue damage resulting in loss of sensing or capture or both, or MR-induced stimulation on leads resulting in continuous capture, VT/VF, and/or hemodynamic collapse. 

    See the device manual for detailed information regarding the implant procedure, indications, contraindications, warnings, precautions, and potential complications/adverse events. See the appropriate product MRI SureScan Technical Manual before performing an MRI Scan. For further information, please call Medtronic at 1-800-328-2518 and/or consult www.medtronic.com or www.mrisurescan.com.

    CRT IPGs & CRT ICDs ISW

    Brief statement: Medtronic CRT IPG and CRT ICD

    Indications

    CRT-Ps are indicated for NYHA Functional Class III and IV patients who remain symptomatic despite stable, optimal heart failure medical therapy and have a LVEF ≤ 35% and a prolonged QRS duration and for NYHA Functional Class I, II, or III patients who have a LVEF ≤ 50%, are on stable, optimal heart failure medical therapy if indicated and have atrioventricular block (AV block) that are expected to require a high percentage of ventricular pacing that cannot be managed with algorithms to minimize right ventricular pacing.  Optimization of heart failure medical therapy that is limited due to AV block or the urgent need for pacing should be done post implant. Rate adaptive pacing is provided for those patients developing a bradycardia indication who might benefit from increased pacing rates concurrent with increases in activity. Dual chamber and atrial tracking modes are indicated for patients who may benefit from maintenance of AV synchrony. Antitachycardia pacing (ATP) is indicated for termination of atrial tachyarrhythmias in patients with one or more of the above pacing indications.

    CRT-Ds are indicated for ventricular antitachycardia pacing and ventricular defibrillation for automated treatment of life-threatening ventricular arrhythmias and for providing cardiac resynchronization therapy in heart failure patients on stable, optimal heart failure medical therapy if indicated, and meet any of the following classifications: New York Heart Association (NYHA) Functional Class III or IV and who have a left ventricular ejection fraction < 35% and a prolonged QRS duration. Left bundle branch block (LBBB) with a QRS duration > 130 ms, left ventricular ejection fraction < 30%, and NYHA Functional Class II. NYHA Functional Class I, II, or III and who have left ventricular ejection fraction ≤ 50% and atrioventricular block (AV block) that are expected to require a high percentage of ventricular pacing that cannot be managed with algorithms to minimize right ventricular pacing. Optimization of heart failure medical therapy that is limited due to AV block or the urgent need for pacing should be done post implant. Some CRT-Ds are also indicated for use in patients with atrial tachyarrhythmias, or those patients who are at significant risk for developing atrial tachyarrhythmias. The RV Lead Integrity Alert (LIA) feature is intended primarily for patients who have a Medtronic CRT-D device and a Sprint Fidelis lead (Models 6949, 6948, 6931, and 6930), based on performance data. The RV LIA feature may not perform as well with a St. Jude Riata/Durata lead or a Boston Scientific Endotak lead as it does when used with a Medtronic Sprint Fidelis lead. This is because different lead designs may have different failure signatures and conditions that may or may not be detected early by the RV LIA feature.

    A complete SureScan system is required for use in the MR environment.

    Contraindications

    CRT-Ps are contraindicated for concomitant implant with another bradycardia device and concomitant implant with an implantable cardioverter defibrillator. There are no known contraindications for the use of pacing as a therapeutic modality to control heart rate. The patient’s age and medical condition, however, may dictate the particular pacing system, mode of operation, and implant procedure used by the physician. Rate-responsive modes may be contraindicated in those patients who cannot tolerate pacing rates above the programmed Lower Rate. Dual chamber sequential pacing is contraindicated in patients with chronic or persistent supraventricular tachycardias, including atrial fibrillation or flutter. Asynchronous pacing is contraindicated in the presence (or likelihood) of competition between paced and intrinsic rhythms. Single chamber atrial pacing is contraindicated in patients with an AV conduction disturbance. Anti-tachycardia pacing (ATP) therapy is contraindicated in patients with an accessory antegrade pathway.

    CRT-Ds are contraindicated in patients experiencing tachyarrhythmias with transient or reversible causes including, but not limited to, the following: acute myocardial infarction, drug intoxication, drowning, electric shock, electrolyte imbalance, hypoxia, or sepsis; patients who have a unipolar pacemaker implanted, patients with incessant ventricular tachycardia (VT) or ventricular fibrillation (VF), and patients whose primary disorder is chronic atrial tachyarrhythmia with no concomitant VT or VF.

    Warnings and precautions 

    A complete SureScan system is required for use in the MR environment. Before performing an MRI scan, refer to the CRT-P or CRT-D MRI SureScan Technical Manual for  MRI-specific warnings and precautions. A complete SureScan pacing system includes a SureScan device with Medtronic SureScan leads or a Model 6725 pin plug for the right atrial port. To verify that components are part of a SureScan system, visit www.mrisurescan.com. For a CRT-D SureScan system, when a single coil SureScan defibrillation lead is used, a Medtronic DF-1 pin plug must be secured in the SVC port to make a complete SureScan defibrillation system. Any other combination may result in a hazard to the patient during an MRI scan.

    Changes in a patient’s disease and/or medications may alter the efficacy of the device’s programmed parameters. Patients should avoid sources of magnetic and electromagnetic radiation to avoid possible underdetection, inappropriate sensing and/or therapy delivery, tissue damage, induction of an arrhythmia, device electrical reset or device damage. Do not place transthoracic defibrillation paddles directly over the device.

    Certain programming and device operations may not provide cardiac resynchronization. Also for CRT-Ps, Elective Replacement Indicator (ERI) results in the device switching to VVI pacing at 65 ppm. In this mode, patients may experience loss of cardiac resynchronization therapy and/or loss of AV synchrony. For this reason, the device should be replaced prior to ERI being set. Use of the device should not change the application of established anticoagulation protocols.

    Patients and their implanted systems must be screened to meet the following requirements for MRI: no implanted lead extenders, lead adaptors, or abandoned leads; no broken leads or leads with intermittent electrical contact as confirmed by lead impedance history; a SureScan system implanted in the left or right pectoral region. Additionally, for patients whose device will be programmed to an asynchronous pacing mode when MRI SureScan is programmed to On, no diaphragmatic stimulation is present at a pacing output of 5.0 V and at a pulse width of 1.0 ms. For pacemaker-dependent patients, it is not recommended to perform an MRI scan if the right ventricular (RV) lead pacing capture threshold is greater than 2.0 V at 0.4 ms. A higher pacing capture threshold may indicate an issue with the implanted lead. 

    Potential adverse events

    Potential adverse events include, but are not limited to, rejection phenomena, erosion through the skin, muscle or nerve stimulation, oversensing, failure to detect and/or terminate arrhythmia episodes, and surgical complications such as hematoma, infection, inflammation, and thrombosis. An additional complication for CRT-Ds is the acceleration of ventricular tachycardia.

    Potential MRI complications for the SureScan system include, but are not limited to, lead electrode heating and tissue damage resulting in loss of sensing or capture or both, or MRI induced currents on leads resulting in continuous capture, VT/VF, and/or hemodynamic collapse; spontaneous tachyarrhythmia occurring during the scan that is not detected and treated because tachyarrhythmia detection is suspended while MRI SureScan is programmed to On; potential for VT/VF induction when the patient is programmed to an asynchronous pacing mode during MRI SureScan; device heating resulting in tissue damage in the implant pocket or patient discomfort or both; or damage to the functionality or mechanical integrity of the device resulting in the inability of the device to communicate with the programmer. See the CRT-P or CRT-D MRI SureScan Technical Manual before performing an MRI Scan.

    See the appropriate CRT-P or CRT-D Device Manuals for detailed information regarding the implant procedure, indications, contraindications, warnings, precautions, and potential complications/adverse events. See the appropriate CRT-P or CRT-D MRI SureScan Technical Manual before performing an MRI Scan.

    Achieve Advance™ mapping catheter ISW

    Indications (or intended use)

    The Achieve Advance™ Mapping Catheter is indicated for multiple electrode electrophysiological mapping of the cardiac structures of the heart, i.e., recording or stimulation only. The Achieve Advance™ mapping catheter is designed to obtain electrograms in the atrial regions of the heart.

    Contraindications

    The catheter is contraindicated as follows: 1) For use as an ablation device, 2) For use with transseptal sheaths featuring side holes larger than 1.00 mm (0.04 in) in diameter, 3) Retrograde approach.

    Electrophysiology studies are contraindicated when the patient’s underlying cardiac disease makes it likely that induced arrhythmias will be extremely difficult to terminate and carry a high risk of death, as in the following conditions: An active systemic infection, Left atrial thrombus, Pulmonary vein stents, Prosthetic heart valve (tissue or mechanical), Myxoma, Interatrial baffle or patch, Conditions where the manipulation of the catheter within the heart would be unsafe, Acute myocardial infarction.

    Warnings and precautions

    This catheter is intended only to be used once for a single patient. Do not reuse, reprocess, or resterilize these devices for purpose of reuse. Reuse, reprocessing, or resterilization may compromise the structural integrity of the device or create a risk of contamination of the device that could result in patient injury, illness, or death. This equipment should be used only by or under the supervision of physicians trained in cardiac catheterization procedures. If the sterile packaging of the device is damaged, do not use. Do not connect the mapping catheter to a radiofrequency (RF) generator or use it to deliver RF energy.

    Use of fluoroscopy during catheter manipulation and placement is strongly advised. Take all appropriate measures to minimize x-ray exposure to both patients and clinical staff.

    Avoid positioning the catheter around the chordae tendineae as this increases the likelihood of catheter entrapment within the heart. Avoid catheter entanglement with other catheters, devices, or wires. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Introducing any catheter into the circulatory system entails the risk of air or gas embolism, which can occlude vessels and lead to tissue infarction with serious consequences.

    Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade. Do not use excessive force to advance or withdraw the catheter, especially if resistance is encountered. Do not use the catheter if it is kinked, damaged, or cannot be straightened. Bending or kinking the catheter shaft may compromise the structural integrity of the device and increase the risk of catheter failure. Use only isolated equipment (IEC 606011 Type CF equipment, or equivalent) with the mapping catheter. Do not allow the patient to contact grounded equipment that might produce electrical current leakage during ablation or DCCV (Direct Current CardioVersion). Disconnect the catheter from the catheter connecting cable prior to cardioversion/defibrillation. Do not touch the patient or the catheter during cardioversion/defibrillation.

    Use the mapping catheter only with the Medtronic catheter connecting cable Model 2ACHC, and a compatible mating device with a minimum internal diameter of 1.12 mm (0.044 in) and standard 9 Fr hemostasis valve. The mapping catheter is compatible for use with, and may be used to support and position, all catheters in the Medtronic Arctic Front CryoAblation Catheter family. Cardiac catheterization procedures should be performed only in a fully equipped electrophysiology laboratory. Do not immerse the electrical connectors in fluids or solvents. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing left-sided and transseptal cardiac procedures. Always rotate the mapping catheter in a clockwise direction to prevent tissue damage. Keep in a dry location away from heat and all sources of light.

    Arctic Front Advance™ Cardiac Cryoablation Catheter ISW

    Indications (or intended use)

    The Arctic Front Advance™ and Arctic Front Advance Pro™ cardiac cryoablation catheters are indicated for the treatment of drug refractory recurrent symptomatic paroxysmal and persistent atrial fibrillation (episode duration less than 6 months).

    The Arctic Front Advance™ and Arctic Front Advance Pro™ cardiac cryoablation catheters are also indicated for the treatment of recurrent symptomatic paroxysmal atrial fibrillation as an alternative to antiarrhythmic drug therapy as an initial rhythm control strategy.

    Contraindications

    Use of the cryoballoon is contraindicated: 1) In the ventricle because of the danger of catheter entrapment in the chordae tendineae, 2) In patients with one or more pulmonary vein stents, 3) In patients with cryoglobulinemia, 4) In patients with active systemic infections, and 5) In conditions where the manipulation of the catheter within the heart would be unsafe (e.g., intracardiacmural thrombus).

    Warnings and precautions

    Do not reprocess or resterilize this device for the purpose of reuse. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing left-sided and transseptal cardiac procedures. The Arctic Front family of cryoballoons have not been studied for the safety of changes in anticoagulation therapy in patients with paroxysmal atrial fibrillation. Atrial fibrillation patients with significant left ventricular dysfunction, advanced heart failure, severe left atrial enlargement or significant structural heart disease were excluded from the clinical trials that supported the approved indications. For baseline demographics and clinical characteristics of the patients studied, please see the Clinical Summaries listed in the instructions for use. Do not inflate the balloon inside the sheath or while the catheter is positioned inside a pulmonary vein. Always inflate the balloon in the atrium and then position it at the pulmonary vein ostium. If the balloon cannot be inflated or deflated using the CryoConsole, have a Manual Retraction Kit on hand during the procedure. (Refer to the CryoConsole Operator’s Manual for more detailed instructions on the Manual Retraction Kit). Disconnect the catheter’s electrical connection before cardioversion or defibrillation.

    Catheter handling:

    • Use extreme care when manipulating the catheter.
    • Do not use excessive force to advance, withdraw, or rotate the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • If the catheter becomes kinked or damaged while in the patient, remove it and use a new catheter.
    • Straighten the shaft before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or balloon segment.
    • Catheter advancement should be performed using fluoroscopy or other appropriate techniques.
    • Do not position the cryoballoon catheter within the tubular portion of the pulmonary vein.

    Do not advance the balloon beyond the guide wire or circular mapping catheter to reduce the risk of tissue damage. Ensure that the guide wire or circular mapping catheter is inserted into the catheter and through the balloon portion for adequate support during vascular access insertion. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Do not pull on the balloon catheter, circular mapping catheter, sheath, umbilical cables, or CryoConsole while the balloon catheter or circular mapping catheter are frozen to tissue. Before moving these components, use appropriate techniques to ensure that the balloon catheter and circular mapping catheter are not adhered to tissue.

    Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. The use of fluoroscopy during catheter ablation procedures presents the potential for significant x-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women. Flush the guide wire lumen before initial insertion and then frequently throughout the procedure to prevent coagulation of blood in the lumen. Flush the guide wire lumen with saline after each contrast injection. Use only 0.081 cm (0.032 in) or 0.089 cm (0.035 in) guide wires with the catheter. Do not connect the cryoablation catheter to a radiofrequency (RF) generator or use it to deliver RF energy. Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole and catheters. Avoid catheter entanglement with other catheters, devices, or wires.

    Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole. Always deflate the balloon and withdraw the balloon into the transseptal sheath before removing the balloon from the left atrium. If the sterile packaging or catheter is damaged, do not use the catheter. Use only Medtronic cryoablation catheters, 12 FR inner diameter sheaths, circular mapping catheters, refrigerant tanks, and components with the CryoConsole. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. This cryoablation system should be performed only in a fully equipped facility under the supervision of physicians trained in cryoablation procedures.

    Potential adverse events or potential complications

    Potential complications/adverse events from cardiac catheterization and ablation include, but are not limited to, the following: Access site complications (e.g., bruising, ecchymosis); Anemia; Anxiety; Arrhythmia (e.g., atrial flutter, bradycardia, heart block, tachycardia); Back pain; Bleeding from puncture sites; Bronchial constriction; Bronchial fistula; Bronchitis; Bruising; Cardiac tamponade; Cardiopulmonary arrest; Cerebral vascular accident; Chest discomfort/pain/pressure; Cold feeling; Coronary artery spasm; Cough; Death; Diarrhea; Dizziness; Embolism; Esophageal damage (including esophageal fistula); Fatigue; Fever; Headache; Hemoptysis; Hypotension/Hypertension; Infection (e.g., pericarditis, sepsis, urinary); Lightheadedness; Myocardial infarction; Nausea/vomiting; Perforation; Pericardial effusion; Phrenic nerve injury; Pleural effusion; Pneumonia; Pneumothorax; Pseudoaneurysm; Pulmonary edema; Pulmonary hemorrhage; Pulmonary vein dissection; Pulmonary vein stenosis; Shivering; Shortness of breath; Sore throat; Transient ischemic attack; Vagal nerve injury (e.g., gastroparesis); Vasovagal reaction; Visual Changes (e.g., blurred vision).

    DiamondTemp™ Ablation Catheter ISW

    Indications (intended use)

    The DiamondTemp™ ablation catheter is indicated for use in cardiac electrophysiological mapping (stimulation and recording) and for treatment of drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation when used in conjunction with the DiamondTemp™ RF generator and accessories (DiamondTemp™ catheter-to-RF generator cable, DiamondTemp™ GenConnect™ cable, DiamondTemp™ EGM cable, DiamondTemp™ irrigation pump, DiamondTemp™ irrigation tubing set) and compatible mapping system.

    Contraindications

    Use of the DiamondTemp™ catheter is contraindicated for: 1) patients with active systemic infection, 2) patients with prosthetic valves, 3) patients with intracardiac thrombus or myxoma or interatrial baffle or patch via transseptal approach, 4) patients unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation, 5) pregnant women and children < 18 years of age, and 6) patients who are hemodynamically unstable.

    Warnings and precautions

    Cardiac ablation procedures should be performed only by physicians trained in the techniques of radiofrequency (RF) catheter ablation in a fully equipped electrophysiology (EP) laboratory. The catheter is for single use only. Do not reprocess or resterilize. Reusing, reprocessing, or resterilizing may compromise the structural integrity of the device or lead to product failure, which may result in patient injury, illness, or death. Reuse, reprocessing, or resterilizing may also create a risk of contamination of the device. Contamination may lead to injury, illness, or death of the patient. Pacemakers, implantable cardioverter defibrillators (ICDs), and leads can be adversely affected by RF signals. ICDs should be deactivated prior to ablation, precautions should be taken when the catheter is in close proximity to leads, and complete system analysis should be performed after ablation. Long-term risks of RF ablation lesions have not been established. Ablation too close to the esophageal area can result in esophageal fistula. Ablation near the AV node can cause permanent or partial conduction block. To ensure proper operation of the tissue contact impedance measurement function, all four electrodes and six thermocouples on the catheter tip must protrude from the distal tip of the guiding sheath. Carefully monitor the tissue contact impedance before delivery of RF energy. Do not place the RF electrode in proximity to any other mapping or ablation electrodes, as this may cause inadvertent, ineffective, or unsafe tissue ablation and may increase chances of char, coagulum, or steam pops. Although a higher contact impedance value typically indicates acceptable tissue contact, and low contact impedance values typically indicate lack of tissue contact, caution should be exercised. Areas of previously ablated tissue may also display a low contact impedance value. Other parameters, such as EGM, fluoroscopic images, and intracardiac ultrasound should be monitored before deciding to apply RF. Stimulation of cardiac tissues caused by pacing stimulus or RF energy may lead to inadvertent induction of arrhythmias. These arrhythmias may require defibrillation that could also result in skin burns. Do not use the catheter for epicardial ablation. Using ablation parameters (such as temperature set-point, ablation duration, or irrigation flow rate) other than those recommended by Medtronic may be hazardous to patients. Exercise caution and sound medical reasoning when deciding to deviate from recommended parameters. Perform catheter advancement under fluoroscopic guidance in conjunction with internal contact, electrograms, and impedance monitoring to minimize the risk of cardiac damage, perforation, or tamponade. Tip-to-tissue contact impedance is actively monitored only before and after ablation. During ablation, use caution when the temperature drops suddenly. A drop in temperature may be associated with loss of tissue contact. In case of steam pop or automatic shut off, discontinue RF energy. Remove the catheter for visual inspection and check for coagulum, charring, or other catheter defects.

    Manual prebending of the distal curve may damage the steering mechanism and may cause patient injury. Do not attempt ablation with the catheter without the use of the DiamondTemp™ irrigation pump and DiamondTemp™ generator and approved accessories. Do not attempt ablation without the use of the irrigation pump. Before attempting ablation, make sure the pump flow rate is at the minimum continuous flow and the pump is actively communicating with the generator. The potential adverse events that may be associated with ablation procedures can vary greatly in frequency and severity and may necessitate additional medical intervention, including surgery. Carefully review the specific indications, contraindications, warnings, precautions, and adverse events included with each DiamondTemp™ catheter, prior to use of the DiamondTemp™ generator or irrigation pump. The irrigation pump is designed for use only with sterile heparinized normal saline solution. Specified flow-rate accuracy may not be maintained when used with incompatible fluids or delivery devices. The air bubble detector is disabled during irrigation pump priming and purging functions. Do not prime or purge the catheter when it is inserted in the vasculature of the patient. Do not remove the irrigation tubing set from the irrigation pump while the tubing set is in-line with a catheter that is inside the patient. The DiamondTemp™ generator connection box E is to be used with the DiamondTemp™ ablation system and Ensite™ cardiac mapping and navigation systems configured to use NavX™ navigation technology. Use with other systems has not been assessed and may compromise patient or operator safety. Do not connect the generator connection box E to the Ensite™ amplifier with both the primary and secondary connectors. Only connect using one of the connector options.

    Potential adverse events or potential complications

    Potential complications/adverse events from cardiac catheterization and ablation include, but are not limited to, the following: abnormal vision; air embolism; anaphylaxis; anemia; aneurysm; angina; arrhythmia (including new or worsening of existing condition, or requiring cardioversion); arterial or venous thrombus; atrial septal defect; AV fistula; cardiac arrest; cardiac tamponade; catheter entrapment leading to valve or heart wall damage; catheter insertion site hematoma; chest pain (nonspecific); congestive heart failure exacerbation; component damage to ICD or pacemaker; coronary artery dissection; death; dislodgement of implantable device or permanent pacing lead; dizziness; embolic events, including infarction of other tissues, coronary, pulmonary, and bowel structures; endocarditis; esophageal damage or necrosis; exacerbation of COPD; exacerbation of pre-existing atrial fibrillation; fluid overload; gastroparesis or GI event; hemorrhage; hemothorax; hypotension; hypoxia; inadvertent AV block; infection; myocardial infarction; neck pain, back pain, or groin pain; palpitations; perforation (cardiac); pericardial effusion; pericarditis; peripheral venous thrombosis; phrenic nerve damage; pleural effusion; pneumonia; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary vein stenosis; radiation injury resulting in dermatitis, erythema, etc.; renal insufficiency or failure; respiratory failure; seizure; sepsis; skin burns; stroke or cerebrovascular incident; syncope; thromboembolic event; transient ischemic attack; vasovagal reaction; ventricular arrhythmia; vessel wall or valvular damage or insufficiency.

    Freezor™ Cardiac Cryoablation Catheter ISW

    Freezor™ cardiac cryoablation catheter

    Indications

    The Freezor™ cardiac cryoablation catheter, CryoConsole™ system, and related accessories are indicated for the cryoablation of the conducting tissues of the heart in the treatment of adult and pediatric patients over two years of age, with atrioventricular nodal reentrant tachycardia (AVNRT).

    Contraindications

    This device is contraindicated in patients with active systemic infection, cryoglobulinemia, intracardiac mural thrombus, myxoma, interatrial baffle or patch.

    Warnings/Precautions

    Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular (AV) block. Immediately terminate energy delivery if partial or complete AV block is noted. Cryoablation involving coronary vessels has been associated with subsequent clinically significant arterial stenosis. Care should be taken to minimize unnecessary contact with coronary vessels during cryoablation. Endotoxins may cause pyrogenic responses in patients including inflammation and fever which can result in anaphylactic shock and death. Caution should be used with regard to endotoxins in pediatric populations as standard endotoxin limits do not differentiate between adult and pediatric populations. Ethylene oxide residuals remaining after sterilization are known to cause a potential increase in a number of biological effects including irritation, organ damage, mutagenicity and carcinogenicity. Calculations for ethylene oxide and ethylene chlorohydrin residuals indicate that the risk of these effects may be increased in patients under 3.8 kg. Avoid catheter entanglement with other catheters devices or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Do not re-use, reprocess, or resterilize this device for purpose of reuse. This device is intended only to be used once for a single patient. The use of CryoMapping mode does not prevent injuries to the patient. CryoMapping mode is used to determine if the site is appropriate for ablation. The Freezor™ catheter contains a pressurized refrigerant during operation. Release of this gas into the circulatory system due to equipment failure or misuse could result in gas embolism. Do not pull on the catheter, sheath, umbilical cables, or console while the catheter tip is frozen to the tissue, as this may lead to tissue injury. Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Do not connect the Freezor™ catheter to any radiofrequency (RF) generator or use the Freezor™ catheter to deliver RF ablation energy. Before powering up an RF generator of applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. The use of fluoroscopy during catheter ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women. Avoid positioning the catheter around the chordae tendineae, as this increases the likelihood of catheter entrapment within the heart. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue).

    Catheter handling: 

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade. 
    • Do not use excessive force to advance, withdraw, the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • Straighten the cooling segment before inserting or withdrawing the catheter.

    Contraindications

    Use of Freezor™ MAX cardiac cryoablation catheter is contraindicated in patients with active systemic infections, in patients with cryoglobulinemia, intracardiac mural thrombus, myxoma or interatrial baffle or patch. The Freezor™ MAX cardiac cryoablation catheter is also contraindicated in patients with a body mass under 4.4 kg.

    Warnings/Precautions

    Do not reuse or reprocess this device for purpose of reuse. This catheter is intended only to be used once for a single patient. Do not connect the cryoablation catheter to a radiofrequency (RF) generator or use it to deliver RF energy. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation.

    Catheter handling:

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade.
    • Do not use excessive force to advance, withdraw the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened. Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Avoid positioning the catheter around the chordae tendineae. The catheter contains pressurized refrigerant during operation. Release of this gas into the circulatory system due to equipment failure or misuse could result in gas embolism. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Use adequate fluoroscopic visualization or other appropriate visualization technique during a transaortic approach to avoid placing the ablation catheter within the coronary vasculature. Do not pull on the catheter, sheath, umbilical cables, or console while the catheter is frozen to the tissue, as this may lead to tissue injury. Always advance and withdraw components slowly to minimize the vacuum created. Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular block.

    Perform cryoablation procedures only within the environmental parameters. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. The use of fluoroscopy during catheter ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the catheter in pregnant women. Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The safety of the catheter in the MR environment is unknown (such as any heating, migration, or image artifacts). Scanning a patient during the use of this device may result in patient injury. Avoid catheter entanglement with other catheters, devices, or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. If the device is damaged or the integrity of the sterilization barrier has been compromised, do not use the product. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system.

    The Freezor™ MAX catheter was not studied for safety of changes in anticoagulation therapy in patients with paroxysmal atrial fibrillation. This equipment should be used only by physicians that perform cryoablation procedures. Cryoablation procedures should be performed only in a fully equipped facility.

    Freezor™ Xtra cardiac cryoablation catheter

    Indications

    The Freezor™ Xtra cardiac cryoablation catheter, CryoConsole™ system, and related accessories are indicated for the cryoablation of the conducting tissues of the heart in the treatment of adult and pediatric patients over two years of age with atrioventricular nodal reentrant tachycardia (AVNRT). The Freezor™ Xtra catheter is also intended for minimally invasive cardiac surgery procedures, including surgical treatment of cardiac arrhythmias. The Freezor™ Xtra catheter freezes the target tissue and blocks the electrical conduction by creating an inflammatory response or cryonecrosis.

    Contraindications

    The Freezor™ Xtra cardiac cryoablation catheter is contraindicated in patients with the following conditions:

    • Active systemic infections
    • Cryoglobulinemia
    • Intracardiac mural thrombus
    • Myxoma
    • Interatrial baffle or patch

    Warnings/Precautions

    Do not reuse, reprocess, or resterilize this catheter for purpose of reuse. This catheter is intended only to be used once for a single patient. Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular (AV) block. Immediately terminate energy delivery if partial or complete AV block is noted. The use of CryoMapping mode does not prevent injuries to the patient. CryoMapping mode is used to determine if the site is appropriate for ablation. The catheter contains pressurized refrigerant during operation. Release of this gas into the body or circulatory system due to equipment failure or misuse could result in gas embolism, pericardial tamponade, tissue emphysema, or other patient injury. Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Endotoxins may cause pyrogenic responses in patients including inflammation and fever which can result in anaphylactic shock and death. Caution should be used with regard to endotoxins in pediatric populations as standard endotoxin limits do not differentiate between adult and pediatric populations. Ethylene oxide residuals remaining after sterilization are known to cause a potential increase in a number of biological effects including irritation, organ damage, mutagenicity, and carcinogenicity. Calculations for ethylene oxide and ethylene chlorohydrin residuals indicate that the risk of these effects may be increased in patients under 3.8kg. Avoid catheter entanglement with other catheters, devices, or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Do not pull on the Freezor™ Xtra catheter, sheath, umbilical cables, or console while the catheter is frozen to the tissue, as this may lead to tissue injury. Do not connect the Freezor™ Xtra catheter to a radiofrequency (RF) generator or use it to deliver RF ablation energy. Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. The use of fluoroscopy during ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women.

    Catheter handling: 

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade.
    • Do not use excessive force to advance or withdraw the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The Freezor™ Xtra catheter has not been evaluated for safety and compatibility in the magnetic resonance (MR) environment. Scanning a patient during the use of this device may result in patient injury. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system. If the sterile packaging or catheter is damaged, do not use the catheter. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation. Cryoablation involving coronary vessels with liquid nitrous oxide systems has been associated with subsequent clinically significant arterial stenosis. Care should be taken to minimize unnecessary contact with coronary vessels during cryoablation.

    Avoid positioning the catheter around the chordae tendineae, as this increases the likelihood of catheter entrapment within the heart. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing endocardial right-sided procedures. This equipment should be used only by physicians that perform cardiac ablation.

    Potential Complications

    Potential complications that may be associated with cardiac catheterization and ablation listed alphabetically below include, but are not limited to: Access site complications including, hematoma, infection, thrombosis, ecchymosis, AV fistula, bleeding from puncture site, hemorrhage; arrhythmias (such as atrial fibrillation, atrial flutter, tachycardia); cardiac arrest and/or death; chest discomfort, pain or pressure; coronary artery spasm/stenosis; damage to heart tissue or vasculature; endocarditis; entrapment; heart block, requiring permanent pacemaker; hemothorax; infection; perforation of venous, cardiac or surrounding tissue, pericardial effusion, tamponade; pericarditis; phrenic nerve injury; pleural effusion; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary embolism; stroke; tissue infarction (such as myocardial infarction or renal infarction); thrombus; transient ischemic attack; vagal nerve injury (such as gastroparesis); vasovagal reaction.

    PulseSelect™ Pulsed Field Ablation System ISW

    Indications (or intended use)

    The PulseSelect™ pulsed field ablation (PFA) system is indicated for use in cardiac electrophysiological mapping (stimulation and recording) and for treatment of drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation or persistent atrial fibrillation (episode duration less than one year).

    Contraindications

    The PulseSelect™ PFA loop catheter is contraindicated for use in patients with the following conditions:

    • Active systemic infections
    • A known sensitivity to Heparin
    • Blood clotting abnormalities
    • Permanently implanted metallic objects in the left atrium

    The catheter is also contraindicated in conditions where the manipulation of the catheter within the heart would be unsafe, such as intracardiac mural thrombus.

    The catheter is not recommended for use in patients who cannot undergo standard anticoagulation protocol for a left-sided cardiac procedure, or who have had a recent coagulopathy or embolic event.

    Warnings and precautions

    To reduce the possibility of hazards associated with use of the PulseSelect™ PFA loop catheter: 

    • Use the catheter only in the recommended anatomical location.
    • Maintain the catheter position during the ablation.
    • If coughing occurs, reposition the catheter more proximally and review sedation management.
    • Ensure electrodes are not in contact with any metal during ablations (for example the guide wire).
    • Maintain substantially circular array to ensure uniform field distribution.
    • If the electrode array is deployed to deliver ablation energy, avoid continuing to move the slide control forward to prevent the guide wire lumen from coming too close to the electrode array.

    It is recommended that the array be captured while it is submerged to help reduce the possibility of air becoming entrapped around the electrode array during capture and catheter insertion.

    Catheter integrity

    Use care to avoid damage to the catheter.

    • Do not bend or kink the leading end of the catheter. Doing so could cause damage to the catheter lumen and make it unusable.
    • Monitor the catheter throughout the procedure. If a flash is observed in the luer, replace the catheter immediately.

    Electrode-electrode contact

    Avoid contact between electrodes. Contact between electrodes may create a short circuit.

    Embolism risk

    Introducing any catheter or sheath into the circulatory system entails the risk of air, gas, or thromboembolism, which can occlude vessels and lead to tissue infarction with serious consequences.

    • Avoid unnecessary catheter exchanges to minimize sheath-related embolic events.
    • Always advance and withdraw components slowly to minimize the vacuum created and the risk of air embolism.
    • Aspirate and flush the sheath frequently to help minimize the potential for embolic events resulting from the introduction of air or clot formation within the sheath.

    Fluoroscopy use during catheter placement

    Only perform catheter ablation after giving adequate attention to the potential radiation exposure associated with the procedure and taking steps to minimize this exposure. Give careful consideration before using the device in pregnant women.

    For single use only

    The PFA catheter is intended only to be used once for a single patient. Do not reuse, reprocess, or resterilize the PFA catheter.

    Careful manipulation of the catheter is necessary to avoid cardiac damage, perforation, or tamponade.

    • Do not use excessive force to advance, withdraw, or rotate the catheter, especially if resistance is encountered. Excessive force may lead to catheter damage and blood loss.
    • Use imaging guidance during catheter advancement, manipulation, and placement.
    • Vascular perforation is an inherent risk of catheter placement.
    • Performing ablation with the PFA catheter array inside the sheath may result in damage to the array or the sheath and should be avoided.
    • Performing steering manipulation with the PFA catheter array inside the sheath may result in damage to the catheter steering mechanism or the sheath and should be avoided.
    • The PFA generator is capable of delivering significant energy. Do not touch the ablation electrodes of the PFA catheter while operating the generator.
    • If the system is to be tested outside of the body, the electrode array must be immersed in saline solution in a plastic container. Never test PFA delivery in direct contact with skin.

    Use of imaging during catheter manipulation and placement is strongly advised. Manipulating the catheter without imaging may result in damage to cardiac and vascular structures.

    Other devices, wires, or catheters

    Avoid catheter entanglement with other devices, wires, or catheters, for example, intracardiac echo catheters. Failure to do so may increase the risk of entrapment of the array or damage to the array, which may affect retrieval of the device into the transseptal sheath.

    Phrenic nerve injury

    To reduce the potential for phrenic nerve injury, assess for proximity of the ablation catheter to the nerve using an appropriate technique such as pacing for local phrenic nerve capture or using the test pulse feature before ablation. Stop ablation immediately if phrenic nerve impairment is observed and assess for injury.

    Sheath and guide wire required

    Do not attempt to advance or withdraw the catheter through the vasculature without the use of a sheath and guide wire, as it may result in damage to cardiac and vascular structures.

    Implanted devices, such as pacemakers and implantable cardioverter-defibrillators (ICDs), may be adversely affected by PFA energy.

    • Keep external sources of pacing and defibrillation available during ablation.
    • Program pacemaker sensing parameters to asynchronous pacing to ensure that PFA energy is not sensed as an intrinsic event.
    • Deactivate ICD detection during the delivery of PFA energy.
    • Perform complete implantable device testing before and after ablation.
    • Monitor surface and intracardiac electrograms or vital signs during PFA energy delivery to assess for device interaction. Take appropriate action if any interaction is detected.
    • Refer to the appropriate implantable device technical manual for additional information.

    Electrical safety requirements

    The PFA generator meets the requirements of IEC 60601-1. It is the user’s responsibility after installation to verify and ensure that the generator meets the applicable local electrical safety requirements.

    Electric shock

    To avoid risk of electric shock, this equipment must only be connected to a supply main with protective earth.

    Electromagnetic interference (EMI) radiated

    The generator emits energy during ablation at a frequency level that may cause EMI with unshielded electronic equipment. To minimize EMI, the generator should be moved away from any other electronic device. If EMI is apparent during the application of energy, EMI may be reduced by repositioning the generator or other equipment.

    Electromagnetic interference (EMI) susceptibility

    The generator has been designed to minimize EMI. If interference should occur, move the generator away from the device generating the interference or place the generator at a different angle.

    Leakage current from connected devices

    Use only isolated equipment (IEC 60601-1 Type CF equipment or equivalent) with the PFA system and catheters, or patient injury or death may occur.

    Potential adverse events or potential complications

    Potential adverse events associated with cardiac catheter ablation procedures include, but are not limited to, the following conditions:

    • Access site complications (such as, bruising, ecchymosis, arteriovenous fistula, hematoma, pseudoaneurysm)

    Use of fluoroscopy during catheter manipulation and placement is strongly advised. Take all appropriate measures to minimize x-ray exposure to both patients and clinical staff.

    Avoid positioning the catheter around the chordae tendineae as this increases the likelihood of catheter entrapment within the heart. Avoid catheter entanglement with other catheters, devices, or wires. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue).

    Introducing any catheter into the circulatory system entails the risk of air or gas embolism, which can occlude vessels and lead to tissue infarction with serious consequences.

    Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade. Do not use excessive force to advance or withdraw the catheter, especially if resistance is encountered. Do not use the catheter if it is kinked, damaged, or cannot be straightened. Bending or kinking the catheter shaft may compromise the structural integrity of the device and increase the risk of catheter failure. Use only isolated equipment (IEC 60601 Type CF equipment, or equivalent) with the Achieve Mapping Catheter. Do not allow the patient to contact grounded equipment that might produce electrical current leakage during ablation or DCCV (Direct Current CardioVersion). Do not allow any exposed metal portion of the shaft to contact grounded equipment.  Remove the catheter from the patient prior to cardioversion/defibrillation. Do not touch the patient or the catheter during cardioversion/defibrillation. Use the Achieve Mapping Catheter only with Medtronic Achieve Electrical Cable, suitable compatible mating device with a minimum internal diameter of 1.3 mm (0.049”) and standard 9F hemostasis valve. The Achieve Mapping Catheter is compatible for use with the Medtronic Arctic Front CryoAblation Catheter, and may be used to support and position the Arctic Front Catheter. Cardiac catheterization procedures should be performed only in a fully equipped electrophysiology laboratory. Do not immerse the electrical connectors in fluids or solvents. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing left-sided and transseptal cardiac procedures. Always rotate the Achieve Mapping Catheter in a clockwise direction to prevent tissue damage. Keep in a dry location away from heat and sunlight. Do not expose the catheter to organic solvents such as alcohol.

    Arctic Front Advance™ Cardiac Cryoablation Catheter ISW

    Indications (or intended use)

    The Arctic Front Advance™ and Arctic Front Advance Pro™ cardiac cryoablation catheters are indicated for the treatment of drug refractory recurrent symptomatic paroxysmal and persistent atrial fibrillation (episode duration less than 6 months).

    The Arctic Front Advance™ and Arctic Front Advance Pro™ cardiac cryoablation catheters are also indicated for the treatment of recurrent symptomatic paroxysmal atrial fibrillation as an alternative to antiarrhythmic drug therapy as an initial rhythm control strategy.

    Contraindications

    Use of the cryoballoon is contraindicated: 1) In the ventricle because of the danger of catheter entrapment in the chordae tendineae, 2) In patients with one or more pulmonary vein stents, 3) In patients with cryoglobulinemia, 4) In patients with active systemic infections, and 5) In conditions where the manipulation of the catheter within the heart would be unsafe (e.g., intracardiacmural thrombus).

    Warnings and precautions

    Do not reprocess or resterilize this device for the purpose of reuse. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing left-sided and transseptal cardiac procedures. The Arctic Front family of cryoballoons have not been studied for the safety of changes in anticoagulation therapy in patients with paroxysmal atrial fibrillation. Atrial fibrillation patients with significant left ventricular dysfunction, advanced heart failure, severe left atrial enlargement or significant structural heart disease were excluded from the clinical trials that supported the approved indications. For baseline demographics and clinical characteristics of the patients studied, please see the Clinical Summaries listed in the instructions for use. Do not inflate the balloon inside the sheath or while the catheter is positioned inside a pulmonary vein. Always inflate the balloon in the atrium and then position it at the pulmonary vein ostium. If the balloon cannot be inflated or deflated using the CryoConsole, have a Manual Retraction Kit on hand during the procedure. (Refer to the CryoConsole Operator’s Manual for more detailed instructions on the Manual Retraction Kit). Disconnect the catheter’s electrical connection before cardioversion or defibrillation.

    Catheter handling:

    • Use extreme care when manipulating the catheter.
    • Do not use excessive force to advance, withdraw, or rotate the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • If the catheter becomes kinked or damaged while in the patient, remove it and use a new catheter.
    • Straighten the shaft before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or balloon segment.
    • Catheter advancement should be performed using fluoroscopy or other appropriate techniques.
    • Do not position the cryoballoon catheter within the tubular portion of the pulmonary vein.

    Do not advance the balloon beyond the guide wire or circular mapping catheter to reduce the risk of tissue damage. Ensure that the guide wire or circular mapping catheter is inserted into the catheter and through the balloon portion for adequate support during vascular access insertion. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Do not pull on the balloon catheter, circular mapping catheter, sheath, umbilical cables, or CryoConsole while the balloon catheter or circular mapping catheter are frozen to tissue. Before moving these components, use appropriate techniques to ensure that the balloon catheter and circular mapping catheter are not adhered to tissue.

    Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. The use of fluoroscopy during catheter ablation procedures presents the potential for significant x-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women. Flush the guide wire lumen before initial insertion and then frequently throughout the procedure to prevent coagulation of blood in the lumen. Flush the guide wire lumen with saline after each contrast injection. Use only 0.081 cm (0.032 in) or 0.089 cm (0.035 in) guide wires with the catheter. Do not connect the cryoablation catheter to a radiofrequency (RF) generator or use it to deliver RF energy. Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole and catheters. Avoid catheter entanglement with other catheters, devices, or wires.

    Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole. Always deflate the balloon and withdraw the balloon into the transseptal sheath before removing the balloon from the left atrium. If the sterile packaging or catheter is damaged, do not use the catheter. Use only Medtronic cryoablation catheters, 12 FR inner diameter sheaths, circular mapping catheters, refrigerant tanks, and components with the CryoConsole. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. This cryoablation system should be performed only in a fully equipped facility under the supervision of physicians trained in cryoablation procedures.

    Potential adverse events or potential complications

    Potential complications/adverse events from cardiac catheterization and ablation include, but are not limited to, the following: Access site complications (e.g., bruising, ecchymosis); Anemia; Anxiety; Arrhythmia (e.g., atrial flutter, bradycardia, heart block, tachycardia); Back pain; Bleeding from puncture sites; Bronchial constriction; Bronchial fistula; Bronchitis; Bruising; Cardiac tamponade; Cardiopulmonary arrest; Cerebral vascular accident; Chest discomfort/pain/pressure; Cold feeling; Coronary artery spasm; Cough; Death; Diarrhea; Dizziness; Embolism; Esophageal damage (including esophageal fistula); Fatigue; Fever; Headache; Hemoptysis; Hypotension/Hypertension; Infection (e.g., pericarditis, sepsis, urinary); Lightheadedness; Myocardial infarction; Nausea/vomiting; Perforation; Pericardial effusion; Phrenic nerve injury; Pleural effusion; Pneumonia; Pneumothorax; Pseudoaneurysm; Pulmonary edema; Pulmonary hemorrhage; Pulmonary vein dissection; Pulmonary vein stenosis; Shivering; Shortness of breath; Sore throat; Transient ischemic attack; Vagal nerve injury (e.g., gastroparesis); Vasovagal reaction; Visual Changes (e.g., blurred vision).

    DiamondTemp™ Ablation Catheter ISW

    Indications (intended use)

    The DiamondTemp™ ablation catheter is indicated for use in cardiac electrophysiological mapping (stimulation and recording) and for treatment of drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation when used in conjunction with the DiamondTemp™ RF generator and accessories (DiamondTemp™ catheter-to-RF generator cable, DiamondTemp™ GenConnect™ cable, DiamondTemp™ EGM cable, DiamondTemp™ irrigation pump, DiamondTemp™ irrigation tubing set) and compatible mapping system.

    Contraindications

    Use of the DiamondTemp™ catheter is contraindicated for: 1) patients with active systemic infection, 2) patients with prosthetic valves, 3) patients with intracardiac thrombus or myxoma or interatrial baffle or patch via transseptal approach, 4) patients unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation, 5) pregnant women and children < 18 years of age, and 6) patients who are hemodynamically unstable.

    Warnings and precautions

    Cardiac ablation procedures should be performed only by physicians trained in the techniques of radiofrequency (RF) catheter ablation in a fully equipped electrophysiology (EP) laboratory. The catheter is for single use only. Do not reprocess or resterilize. Reusing, reprocessing, or resterilizing may compromise the structural integrity of the device or lead to product failure, which may result in patient injury, illness, or death. Reuse, reprocessing, or resterilizing may also create a risk of contamination of the device. Contamination may lead to injury, illness, or death of the patient. Pacemakers, implantable cardioverter defibrillators (ICDs), and leads can be adversely affected by RF signals. ICDs should be deactivated prior to ablation, precautions should be taken when the catheter is in close proximity to leads, and complete system analysis should be performed after ablation. Long-term risks of RF ablation lesions have not been established. Ablation too close to the esophageal area can result in esophageal fistula. Ablation near the AV node can cause permanent or partial conduction block. To ensure proper operation of the tissue contact impedance measurement function, all four electrodes and six thermocouples on the catheter tip must protrude from the distal tip of the guiding sheath. Carefully monitor the tissue contact impedance before delivery of RF energy. Do not place the RF electrode in proximity to any other mapping or ablation electrodes, as this may cause inadvertent, ineffective, or unsafe tissue ablation and may increase chances of char, coagulum, or steam pops. Although a higher contact impedance value typically indicates acceptable tissue contact, and low contact impedance values typically indicate lack of tissue contact, caution should be exercised. Areas of previously ablated tissue may also display a low contact impedance value. Other parameters, such as EGM, fluoroscopic images, and intracardiac ultrasound should be monitored before deciding to apply RF. Stimulation of cardiac tissues caused by pacing stimulus or RF energy may lead to inadvertent induction of arrhythmias. These arrhythmias may require defibrillation that could also result in skin burns. Do not use the catheter for epicardial ablation. Using ablation parameters (such as temperature set-point, ablation duration, or irrigation flow rate) other than those recommended by Medtronic may be hazardous to patients. Exercise caution and sound medical reasoning when deciding to deviate from recommended parameters. Perform catheter advancement under fluoroscopic guidance in conjunction with internal contact, electrograms, and impedance monitoring to minimize the risk of cardiac damage, perforation, or tamponade. Tip-to-tissue contact impedance is actively monitored only before and after ablation. During ablation, use caution when the temperature drops suddenly. A drop in temperature may be associated with loss of tissue contact. In case of steam pop or automatic shut off, discontinue RF energy. Remove the catheter for visual inspection and check for coagulum, charring, or other catheter defects.

    Manual prebending of the distal curve may damage the steering mechanism and may cause patient injury. Do not attempt ablation with the catheter without the use of the DiamondTemp™ irrigation pump and DiamondTemp™ generator and approved accessories. Do not attempt ablation without the use of the irrigation pump. Before attempting ablation, make sure the pump flow rate is at the minimum continuous flow and the pump is actively communicating with the generator. The potential adverse events that may be associated with ablation procedures can vary greatly in frequency and severity and may necessitate additional medical intervention, including surgery. Carefully review the specific indications, contraindications, warnings, precautions, and adverse events included with each DiamondTemp™ catheter, prior to use of the DiamondTemp™ generator or irrigation pump. The irrigation pump is designed for use only with sterile heparinized normal saline solution. Specified flow-rate accuracy may not be maintained when used with incompatible fluids or delivery devices. The air bubble detector is disabled during irrigation pump priming and purging functions. Do not prime or purge the catheter when it is inserted in the vasculature of the patient. Do not remove the irrigation tubing set from the irrigation pump while the tubing set is in-line with a catheter that is inside the patient. The DiamondTemp™ generator connection box E is to be used with the DiamondTemp™ ablation system and Ensite™ cardiac mapping and navigation systems configured to use NavX™ navigation technology. Use with other systems has not been assessed and may compromise patient or operator safety. Do not connect the generator connection box E to the Ensite™ amplifier with both the primary and secondary connectors. Only connect using one of the connector options.

    Potential adverse events or potential complications

    Potential complications/adverse events from cardiac catheterization and ablation include, but are not limited to, the following: abnormal vision; air embolism; anaphylaxis; anemia; aneurysm; angina; arrhythmia (including new or worsening of existing condition, or requiring cardioversion); arterial or venous thrombus; atrial septal defect; AV fistula; cardiac arrest; cardiac tamponade; catheter entrapment leading to valve or heart wall damage; catheter insertion site hematoma; chest pain (nonspecific); congestive heart failure exacerbation; component damage to ICD or pacemaker; coronary artery dissection; death; dislodgement of implantable device or permanent pacing lead; dizziness; embolic events, including infarction of other tissues, coronary, pulmonary, and bowel structures; endocarditis; esophageal damage or necrosis; exacerbation of COPD; exacerbation of pre-existing atrial fibrillation; fluid overload; gastroparesis or GI event; hemorrhage; hemothorax; hypotension; hypoxia; inadvertent AV block; infection; myocardial infarction; neck pain, back pain, or groin pain; palpitations; perforation (cardiac); pericardial effusion; pericarditis; peripheral venous thrombosis; phrenic nerve damage; pleural effusion; pneumonia; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary vein stenosis; radiation injury resulting in dermatitis, erythema, etc.; renal insufficiency or failure; respiratory failure; seizure; sepsis; skin burns; stroke or cerebrovascular incident; syncope; thromboembolic event; transient ischemic attack; vasovagal reaction; ventricular arrhythmia; vessel wall or valvular damage or insufficiency.

    Freezor™ Cardiac Cryoablation Catheter ISW

    Freezor™ cardiac cryoablation catheter

    Indications

    The Freezor™ cardiac cryoablation catheter, CryoConsole™ system, and related accessories are indicated for the cryoablation of the conducting tissues of the heart in the treatment of adult and pediatric patients over two years of age, with atrioventricular nodal reentrant tachycardia (AVNRT).

    Contraindications

    This device is contraindicated in patients with active systemic infection, cryoglobulinemia, intracardiac mural thrombus, myxoma, interatrial baffle or patch.

    Warnings/Precautions

    Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular (AV) block. Immediately terminate energy delivery if partial or complete AV block is noted. Cryoablation involving coronary vessels has been associated with subsequent clinically significant arterial stenosis. Care should be taken to minimize unnecessary contact with coronary vessels during cryoablation. Endotoxins may cause pyrogenic responses in patients including inflammation and fever which can result in anaphylactic shock and death. Caution should be used with regard to endotoxins in pediatric populations as standard endotoxin limits do not differentiate between adult and pediatric populations. Ethylene oxide residuals remaining after sterilization are known to cause a potential increase in a number of biological effects including irritation, organ damage, mutagenicity and carcinogenicity. Calculations for ethylene oxide and ethylene chlorohydrin residuals indicate that the risk of these effects may be increased in patients under 3.8 kg. Avoid catheter entanglement with other catheters devices or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Do not re-use, reprocess, or resterilize this device for purpose of reuse. This device is intended only to be used once for a single patient. The use of CryoMapping mode does not prevent injuries to the patient. CryoMapping mode is used to determine if the site is appropriate for ablation. The Freezor™ catheter contains a pressurized refrigerant during operation. Release of this gas into the circulatory system due to equipment failure or misuse could result in gas embolism. Do not pull on the catheter, sheath, umbilical cables, or console while the catheter tip is frozen to the tissue, as this may lead to tissue injury. Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Do not connect the Freezor™ catheter to any radiofrequency (RF) generator or use the Freezor™ catheter to deliver RF ablation energy. Before powering up an RF generator of applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. The use of fluoroscopy during catheter ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women. Avoid positioning the catheter around the chordae tendineae, as this increases the likelihood of catheter entrapment within the heart. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue).

    Catheter handling: 

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade. 
    • Do not use excessive force to advance, withdraw, the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system. If the sterile packaging or catheter is damaged, do not use the catheter. This equipment should be used only by physicians that perform cardiac ablation. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing right-sided procedures. The Freezor™ catheter has not been evaluated for safety and compatibility in the magnetic resonance (MR) environment. Scanning a patient during the use of this device may result in patient injury.

    Potential Complications

    Potential complications that may be associated with cardiac catheterization and ablation listed alphabetically below include, but are not limited to: Access site complications including, hematoma, infection, thrombosis, ecchymosis, AV fistula, bleeding from puncture site, hemorrhage; arrhythmias (such as atrial fibrillation, atrial flutter, tachycardia); cardiac arrest and/or death; chest discomfort, pain or pressure; coronary artery spasm/stenosis; damage to heart tissue or vasculature; endocarditis; entrapment; heart block, requiring permanent pacemaker; hemothorax; infection; perforation of venous, cardiac or surrounding tissue, pericardial effusion, tamponade; pericarditis; phrenic nerve injury; pleural effusion; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary embolism; stroke; tissue infarction (such as myocardial infarction or renal infarction); thrombus; transient ischemic attack; vagal nerve injury (such as gastroparesis); vasovagal reaction.

    Contraindications

    Use of Freezor™ MAX cardiac cryoablation catheter is contraindicated in patients with active systemic infections, in patients with cryoglobulinemia, intracardiac mural thrombus, myxoma or interatrial baffle or patch. The Freezor™ MAX cardiac cryoablation catheter is also contraindicated in patients with a body mass under 4.4 kg.

    Warnings/Precautions

    Do not reuse or reprocess this device for purpose of reuse. This catheter is intended only to be used once for a single patient. Do not connect the cryoablation catheter to a radiofrequency (RF) generator or use it to deliver RF energy. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation.

    Catheter handling:

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade.
    • Do not use excessive force to advance, withdraw the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened. Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Avoid positioning the catheter around the chordae tendineae. The catheter contains pressurized refrigerant during operation. Release of this gas into the circulatory system due to equipment failure or misuse could result in gas embolism. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Use adequate fluoroscopic visualization or other appropriate visualization technique during a transaortic approach to avoid placing the ablation catheter within the coronary vasculature. Do not pull on the catheter, sheath, umbilical cables, or console while the catheter is frozen to the tissue, as this may lead to tissue injury. Always advance and withdraw components slowly to minimize the vacuum created. Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular block.

    Perform cryoablation procedures only within the environmental parameters. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. The use of fluoroscopy during catheter ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the catheter in pregnant women. Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The safety of the catheter in the MR environment is unknown (such as any heating, migration, or image artifacts). Scanning a patient during the use of this device may result in patient injury. Avoid catheter entanglement with other catheters, devices, or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. If the device is damaged or the integrity of the sterilization barrier has been compromised, do not use the product. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system.

    The Freezor™ MAX catheter was not studied for safety of changes in anticoagulation therapy in patients with paroxysmal atrial fibrillation. This equipment should be used only by physicians that perform cryoablation procedures. Cryoablation procedures should be performed only in a fully equipped facility.

    Potential Complications

    Freezor™ Xtra cardiac cryoablation catheter

    Indications

    The Freezor™ Xtra cardiac cryoablation catheter, CryoConsole™ system, and related accessories are indicated for the cryoablation of the conducting tissues of the heart in the treatment of adult and pediatric patients over two years of age with atrioventricular nodal reentrant tachycardia (AVNRT). The Freezor™ Xtra catheter is also intended for minimally invasive cardiac surgery procedures, including surgical treatment of cardiac arrhythmias. The Freezor™ Xtra catheter freezes the target tissue and blocks the electrical conduction by creating an inflammatory response or cryonecrosis.

    Contraindications

    The Freezor™ Xtra cardiac cryoablation catheter is contraindicated in patients with the following conditions:

    • Active systemic infections
    • Cryoglobulinemia
    • Intracardiac mural thrombus
    • Myxoma
    • Interatrial baffle or patch

    Warnings/Precautions

    Do not reuse, reprocess, or resterilize this catheter for purpose of reuse. This catheter is intended only to be used once for a single patient. Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular (AV) block. Immediately terminate energy delivery if partial or complete AV block is noted. The use of CryoMapping mode does not prevent injuries to the patient. CryoMapping mode is used to determine if the site is appropriate for ablation. The catheter contains pressurized refrigerant during operation. Release of this gas into the body or circulatory system due to equipment failure or misuse could result in gas embolism, pericardial tamponade, tissue emphysema, or other patient injury. Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Endotoxins may cause pyrogenic responses in patients including inflammation and fever which can result in anaphylactic shock and death. Caution should be used with regard to endotoxins in pediatric populations as standard endotoxin limits do not differentiate between adult and pediatric populations. Ethylene oxide residuals remaining after sterilization are known to cause a potential increase in a number of biological effects including irritation, organ damage, mutagenicity, and carcinogenicity. Calculations for ethylene oxide and ethylene chlorohydrin residuals indicate that the risk of these effects may be increased in patients under 3.8kg. Avoid catheter entanglement with other catheters, devices, or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Do not pull on the Freezor™ Xtra catheter, sheath, umbilical cables, or console while the catheter is frozen to the tissue, as this may lead to tissue injury. Do not connect the Freezor™ Xtra catheter to a radiofrequency (RF) generator or use it to deliver RF ablation energy. Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. The use of fluoroscopy during ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women.

    Catheter handling: 

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade.
    • Do not use excessive force to advance or withdraw the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The Freezor™ Xtra catheter has not been evaluated for safety and compatibility in the magnetic resonance (MR) environment. Scanning a patient during the use of this device may result in patient injury. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system. If the sterile packaging or catheter is damaged, do not use the catheter. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation. Cryoablation involving coronary vessels with liquid nitrous oxide systems has been associated with subsequent clinically significant arterial stenosis. Care should be taken to minimize unnecessary contact with coronary vessels during cryoablation.

    Avoid positioning the catheter around the chordae tendineae, as this increases the likelihood of catheter entrapment within the heart. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing endocardial right-sided procedures. This equipment should be used only by physicians that perform cardiac ablation.

    Potential Complications

    Potential complications that may be associated with cardiac catheterization and ablation listed alphabetically below include, but are not limited to: Access site complications including, hematoma, infection, thrombosis, ecchymosis, AV fistula, bleeding from puncture site, hemorrhage; arrhythmias (such as atrial fibrillation, atrial flutter, tachycardia); cardiac arrest and/or death; chest discomfort, pain or pressure; coronary artery spasm/stenosis; damage to heart tissue or vasculature; endocarditis; entrapment; heart block, requiring permanent pacemaker; hemothorax; infection; perforation of venous, cardiac or surrounding tissue, pericardial effusion, tamponade; pericarditis; phrenic nerve injury; pleural effusion; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary embolism; stroke; tissue infarction (such as myocardial infarction or renal infarction); thrombus; transient ischemic attack; vagal nerve injury (such as gastroparesis); vasovagal reaction.

    PulseSelect™ Pulsed Field Ablation System ISW

    Indications (or intended use)

    The PulseSelect™ pulsed field ablation (PFA) system is indicated for use in cardiac electrophysiological mapping (stimulation and recording) and for treatment of drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation or persistent atrial fibrillation (episode duration less than one year).

    Contraindications

    The PulseSelect™ PFA loop catheter is contraindicated for use in patients with the following conditions:

    • Active systemic infections
    • A known sensitivity to Heparin
    • Blood clotting abnormalities
    • Permanently implanted metallic objects in the left atrium

    The catheter is also contraindicated in conditions where the manipulation of the catheter within the heart would be unsafe, such as intracardiac mural thrombus.

    The catheter is not recommended for use in patients who cannot undergo standard anticoagulation protocol for a left-sided cardiac procedure, or who have had a recent coagulopathy or embolic event.

    Warnings and precautions

    To reduce the possibility of hazards associated with use of the PulseSelect™ PFA loop catheter: 

    • Use the catheter only in the recommended anatomical location.
    • Maintain the catheter position during the ablation.
    • If coughing occurs, reposition the catheter more proximally and review sedation management.
    • Ensure electrodes are not in contact with any metal during ablations (for example the guide wire).
    • Maintain substantially circular array to ensure uniform field distribution.
    • If the electrode array is deployed to deliver ablation energy, avoid continuing to move the slide control forward to prevent the guide wire lumen from coming too close to the electrode array.

    It is recommended that the array be captured while it is submerged to help reduce the possibility of air becoming entrapped around the electrode array during capture and catheter insertion.

    Catheter integrity

    Use care to avoid damage to the catheter.

    • Do not bend or kink the leading end of the catheter. Doing so could cause damage to the catheter lumen and make it unusable.
    • Monitor the catheter throughout the procedure. If a flash is observed in the luer, replace the catheter immediately.

    Electrode-electrode contact

    Avoid contact between electrodes. Contact between electrodes may create a short circuit.

    Embolism risk

    Introducing any catheter or sheath into the circulatory system entails the risk of air, gas, or thromboembolism, which can occlude vessels and lead to tissue infarction with serious consequences.

    • Avoid unnecessary catheter exchanges to minimize sheath-related embolic events.
    • Always advance and withdraw components slowly to minimize the vacuum created and the risk of air embolism.
    • Aspirate and flush the sheath frequently to help minimize the potential for embolic events resulting from the introduction of air or clot formation within the sheath.

    Fluoroscopy use during catheter placement

    Only perform catheter ablation after giving adequate attention to the potential radiation exposure associated with the procedure and taking steps to minimize this exposure. Give careful consideration before using the device in pregnant women.

    For single use only

    The PFA catheter is intended only to be used once for a single patient. Do not reuse, reprocess, or resterilize the PFA catheter.

    Careful manipulation of the catheter is necessary to avoid cardiac damage, perforation, or tamponade.

    • Do not use excessive force to advance, withdraw, or rotate the catheter, especially if resistance is encountered. Excessive force may lead to catheter damage and blood loss.
    • Use imaging guidance during catheter advancement, manipulation, and placement.
    • Vascular perforation is an inherent risk of catheter placement.
    • Performing ablation with the PFA catheter array inside the sheath may result in damage to the array or the sheath and should be avoided.
    • Performing steering manipulation with the PFA catheter array inside the sheath may result in damage to the catheter steering mechanism or the sheath and should be avoided.
    • The PFA generator is capable of delivering significant energy. Do not touch the ablation electrodes of the PFA catheter while operating the generator.
    • If the system is to be tested outside of the body, the electrode array must be immersed in saline solution in a plastic container. Never test PFA delivery in direct contact with skin.

    Use of imaging during catheter manipulation and placement is strongly advised. Manipulating the catheter without imaging may result in damage to cardiac and vascular structures.

    Other devices, wires, or catheters

    Avoid catheter entanglement with other devices, wires, or catheters, for example, intracardiac echo catheters. Failure to do so may increase the risk of entrapment of the array or damage to the array, which may affect retrieval of the device into the transseptal sheath.

    Phrenic nerve injury

    To reduce the potential for phrenic nerve injury, assess for proximity of the ablation catheter to the nerve using an appropriate technique such as pacing for local phrenic nerve capture or using the test pulse feature before ablation. Stop ablation immediately if phrenic nerve impairment is observed and assess for injury.

    Sheath and guide wire required

    Do not attempt to advance or withdraw the catheter through the vasculature without the use of a sheath and guide wire, as it may result in damage to cardiac and vascular structures.

    Implanted devices, such as pacemakers and implantable cardioverter-defibrillators (ICDs), may be adversely affected by PFA energy.

    • Keep external sources of pacing and defibrillation available during ablation.
    • Program pacemaker sensing parameters to asynchronous pacing to ensure that PFA energy is not sensed as an intrinsic event.
    • Deactivate ICD detection during the delivery of PFA energy.
    • Perform complete implantable device testing before and after ablation.
    • Monitor surface and intracardiac electrograms or vital signs during PFA energy delivery to assess for device interaction. Take appropriate action if any interaction is detected.
    • Refer to the appropriate implantable device technical manual for additional information.

    Electrical safety requirements

    The PFA generator meets the requirements of IEC 60601-1. It is the user’s responsibility after installation to verify and ensure that the generator meets the applicable local electrical safety requirements.

    Electric shock

    To avoid risk of electric shock, this equipment must only be connected to a supply main with protective earth.

    Electromagnetic interference (EMI) radiated

    The generator emits energy during ablation at a frequency level that may cause EMI with unshielded electronic equipment. To minimize EMI, the generator should be moved away from any other electronic device. If EMI is apparent during the application of energy, EMI may be reduced by repositioning the generator or other equipment.

    Electromagnetic interference (EMI) susceptibility

    The generator has been designed to minimize EMI. If interference should occur, move the generator away from the device generating the interference or place the generator at a different angle.

    Leakage current from connected devices

    Use only isolated equipment (IEC 60601-1 Type CF equipment or equivalent) with the PFA system and catheters, or patient injury or death may occur.

    Potential adverse events or potential complications

    Potential adverse events associated with cardiac catheter ablation procedures include, but are not limited to, the following conditions:

    • Access site complications (such as, bruising, ecchymosis, arteriovenous fistula, hematoma, pseudoaneurysm)

    Arctic Front Advance™ Cardiac Cryoablation Catheter ISW

    Indications (or intended use)

    The Arctic Front Advance™ and Arctic Front Advance Pro™ cardiac cryoablation catheters are indicated for the treatment of drug refractory recurrent symptomatic paroxysmal and persistent atrial fibrillation (episode duration less than 6 months).

    The Arctic Front Advance™ and Arctic Front Advance Pro™ cardiac cryoablation catheters are also indicated for the treatment of recurrent symptomatic paroxysmal atrial fibrillation as an alternative to antiarrhythmic drug therapy as an initial rhythm control strategy.

    Contraindications

    Use of the cryoballoon is contraindicated: 1) In the ventricle because of the danger of catheter entrapment in the chordae tendineae, 2) In patients with one or more pulmonary vein stents, 3) In patients with cryoglobulinemia, 4) In patients with active systemic infections, and 5) In conditions where the manipulation of the catheter within the heart would be unsafe (e.g., intracardiacmural thrombus).

    Warnings and precautions

    Do not reprocess or resterilize this device for the purpose of reuse. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing left-sided and transseptal cardiac procedures. The Arctic Front family of cryoballoons have not been studied for the safety of changes in anticoagulation therapy in patients with paroxysmal atrial fibrillation. Atrial fibrillation patients with significant left ventricular dysfunction, advanced heart failure, severe left atrial enlargement or significant structural heart disease were excluded from the clinical trials that supported the approved indications. For baseline demographics and clinical characteristics of the patients studied, please see the Clinical Summaries listed in the instructions for use. Do not inflate the balloon inside the sheath or while the catheter is positioned inside a pulmonary vein. Always inflate the balloon in the atrium and then position it at the pulmonary vein ostium. If the balloon cannot be inflated or deflated using the CryoConsole, have a Manual Retraction Kit on hand during the procedure. (Refer to the CryoConsole Operator’s Manual for more detailed instructions on the Manual Retraction Kit). Disconnect the catheter’s electrical connection before cardioversion or defibrillation.

    Catheter handling:

    • Use extreme care when manipulating the catheter.
    • Do not use excessive force to advance, withdraw, or rotate the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • If the catheter becomes kinked or damaged while in the patient, remove it and use a new catheter.
    • Straighten the shaft before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or balloon segment.
    • Catheter advancement should be performed using fluoroscopy or other appropriate techniques.
    • Do not position the cryoballoon catheter within the tubular portion of the pulmonary vein.

    Do not advance the balloon beyond the guide wire or circular mapping catheter to reduce the risk of tissue damage. Ensure that the guide wire or circular mapping catheter is inserted into the catheter and through the balloon portion for adequate support during vascular access insertion. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Do not pull on the balloon catheter, circular mapping catheter, sheath, umbilical cables, or CryoConsole while the balloon catheter or circular mapping catheter are frozen to tissue. Before moving these components, use appropriate techniques to ensure that the balloon catheter and circular mapping catheter are not adhered to tissue.

    Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. The use of fluoroscopy during catheter ablation procedures presents the potential for significant x-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women. Flush the guide wire lumen before initial insertion and then frequently throughout the procedure to prevent coagulation of blood in the lumen. Flush the guide wire lumen with saline after each contrast injection. Use only 0.081 cm (0.032 in) or 0.089 cm (0.035 in) guide wires with the catheter. Do not connect the cryoablation catheter to a radiofrequency (RF) generator or use it to deliver RF energy. Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole and catheters. Avoid catheter entanglement with other catheters, devices, or wires.

    Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole. Always deflate the balloon and withdraw the balloon into the transseptal sheath before removing the balloon from the left atrium. If the sterile packaging or catheter is damaged, do not use the catheter. Use only Medtronic cryoablation catheters, 12 FR inner diameter sheaths, circular mapping catheters, refrigerant tanks, and components with the CryoConsole. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. This cryoablation system should be performed only in a fully equipped facility under the supervision of physicians trained in cryoablation procedures.

    Potential adverse events or potential complications

    Potential complications/adverse events from cardiac catheterization and ablation include, but are not limited to, the following: Access site complications (e.g., bruising, ecchymosis); Anemia; Anxiety; Arrhythmia (e.g., atrial flutter, bradycardia, heart block, tachycardia); Back pain; Bleeding from puncture sites; Bronchial constriction; Bronchial fistula; Bronchitis; Bruising; Cardiac tamponade; Cardiopulmonary arrest; Cerebral vascular accident; Chest discomfort/pain/pressure; Cold feeling; Coronary artery spasm; Cough; Death; Diarrhea; Dizziness; Embolism; Esophageal damage (including esophageal fistula); Fatigue; Fever; Headache; Hemoptysis; Hypotension/Hypertension; Infection (e.g., pericarditis, sepsis, urinary); Lightheadedness; Myocardial infarction; Nausea/vomiting; Perforation; Pericardial effusion; Phrenic nerve injury; Pleural effusion; Pneumonia; Pneumothorax; Pseudoaneurysm; Pulmonary edema; Pulmonary hemorrhage; Pulmonary vein dissection; Pulmonary vein stenosis; Shivering; Shortness of breath; Sore throat; Transient ischemic attack; Vagal nerve injury (e.g., gastroparesis); Vasovagal reaction; Visual Changes (e.g., blurred vision).

    DiamondTemp™ Ablation Catheter ISW

    Indications (intended use)

    The DiamondTemp™ ablation catheter is indicated for use in cardiac electrophysiological mapping (stimulation and recording) and for treatment of drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation when used in conjunction with the DiamondTemp™ RF generator and accessories (DiamondTemp™ catheter-to-RF generator cable, DiamondTemp™ GenConnect™ cable, DiamondTemp™ EGM cable, DiamondTemp™ irrigation pump, DiamondTemp™ irrigation tubing set) and compatible mapping system.

    Contraindications

    Use of the DiamondTemp™ catheter is contraindicated for: 1) patients with active systemic infection, 2) patients with prosthetic valves, 3) patients with intracardiac thrombus or myxoma or interatrial baffle or patch via transseptal approach, 4) patients unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation, 5) pregnant women and children < 18 years of age, and 6) patients who are hemodynamically unstable.

    Warnings and precautions

    Cardiac ablation procedures should be performed only by physicians trained in the techniques of radiofrequency (RF) catheter ablation in a fully equipped electrophysiology (EP) laboratory. The catheter is for single use only. Do not reprocess or resterilize. Reusing, reprocessing, or resterilizing may compromise the structural integrity of the device or lead to product failure, which may result in patient injury, illness, or death. Reuse, reprocessing, or resterilizing may also create a risk of contamination of the device. Contamination may lead to injury, illness, or death of the patient. Pacemakers, implantable cardioverter defibrillators (ICDs), and leads can be adversely affected by RF signals. ICDs should be deactivated prior to ablation, precautions should be taken when the catheter is in close proximity to leads, and complete system analysis should be performed after ablation. Long-term risks of RF ablation lesions have not been established. Ablation too close to the esophageal area can result in esophageal fistula. Ablation near the AV node can cause permanent or partial conduction block. To ensure proper operation of the tissue contact impedance measurement function, all four electrodes and six thermocouples on the catheter tip must protrude from the distal tip of the guiding sheath. Carefully monitor the tissue contact impedance before delivery of RF energy. Do not place the RF electrode in proximity to any other mapping or ablation electrodes, as this may cause inadvertent, ineffective, or unsafe tissue ablation and may increase chances of char, coagulum, or steam pops. Although a higher contact impedance value typically indicates acceptable tissue contact, and low contact impedance values typically indicate lack of tissue contact, caution should be exercised. Areas of previously ablated tissue may also display a low contact impedance value. Other parameters, such as EGM, fluoroscopic images, and intracardiac ultrasound should be monitored before deciding to apply RF. Stimulation of cardiac tissues caused by pacing stimulus or RF energy may lead to inadvertent induction of arrhythmias. These arrhythmias may require defibrillation that could also result in skin burns. Do not use the catheter for epicardial ablation. Using ablation parameters (such as temperature set-point, ablation duration, or irrigation flow rate) other than those recommended by Medtronic may be hazardous to patients. Exercise caution and sound medical reasoning when deciding to deviate from recommended parameters. Perform catheter advancement under fluoroscopic guidance in conjunction with internal contact, electrograms, and impedance monitoring to minimize the risk of cardiac damage, perforation, or tamponade. Tip-to-tissue contact impedance is actively monitored only before and after ablation. During ablation, use caution when the temperature drops suddenly. A drop in temperature may be associated with loss of tissue contact. In case of steam pop or automatic shut off, discontinue RF energy. Remove the catheter for visual inspection and check for coagulum, charring, or other catheter defects.

    Manual prebending of the distal curve may damage the steering mechanism and may cause patient injury. Do not attempt ablation with the catheter without the use of the DiamondTemp™ irrigation pump and DiamondTemp™ generator and approved accessories. Do not attempt ablation without the use of the irrigation pump. Before attempting ablation, make sure the pump flow rate is at the minimum continuous flow and the pump is actively communicating with the generator. The potential adverse events that may be associated with ablation procedures can vary greatly in frequency and severity and may necessitate additional medical intervention, including surgery. Carefully review the specific indications, contraindications, warnings, precautions, and adverse events included with each DiamondTemp™ catheter, prior to use of the DiamondTemp™ generator or irrigation pump. The irrigation pump is designed for use only with sterile heparinized normal saline solution. Specified flow-rate accuracy may not be maintained when used with incompatible fluids or delivery devices. The air bubble detector is disabled during irrigation pump priming and purging functions. Do not prime or purge the catheter when it is inserted in the vasculature of the patient. Do not remove the irrigation tubing set from the irrigation pump while the tubing set is in-line with a catheter that is inside the patient. The DiamondTemp™ generator connection box E is to be used with the DiamondTemp™ ablation system and Ensite™ cardiac mapping and navigation systems configured to use NavX™ navigation technology. Use with other systems has not been assessed and may compromise patient or operator safety. Do not connect the generator connection box E to the Ensite™ amplifier with both the primary and secondary connectors. Only connect using one of the connector options.

    Potential adverse events or potential complications

    Potential complications/adverse events from cardiac catheterization and ablation include, but are not limited to, the following: abnormal vision; air embolism; anaphylaxis; anemia; aneurysm; angina; arrhythmia (including new or worsening of existing condition, or requiring cardioversion); arterial or venous thrombus; atrial septal defect; AV fistula; cardiac arrest; cardiac tamponade; catheter entrapment leading to valve or heart wall damage; catheter insertion site hematoma; chest pain (nonspecific); congestive heart failure exacerbation; component damage to ICD or pacemaker; coronary artery dissection; death; dislodgement of implantable device or permanent pacing lead; dizziness; embolic events, including infarction of other tissues, coronary, pulmonary, and bowel structures; endocarditis; esophageal damage or necrosis; exacerbation of COPD; exacerbation of pre-existing atrial fibrillation; fluid overload; gastroparesis or GI event; hemorrhage; hemothorax; hypotension; hypoxia; inadvertent AV block; infection; myocardial infarction; neck pain, back pain, or groin pain; palpitations; perforation (cardiac); pericardial effusion; pericarditis; peripheral venous thrombosis; phrenic nerve damage; pleural effusion; pneumonia; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary vein stenosis; radiation injury resulting in dermatitis, erythema, etc.; renal insufficiency or failure; respiratory failure; seizure; sepsis; skin burns; stroke or cerebrovascular incident; syncope; thromboembolic event; transient ischemic attack; vasovagal reaction; ventricular arrhythmia; vessel wall or valvular damage or insufficiency.

    Freezor™ Cardiac Cryoablation Catheter ISW

    Freezor™ cardiac cryoablation catheter

    Indications

    The Freezor™ cardiac cryoablation catheter, CryoConsole™ system, and related accessories are indicated for the cryoablation of the conducting tissues of the heart in the treatment of adult and pediatric patients over two years of age, with atrioventricular nodal reentrant tachycardia (AVNRT).

    Contraindications

    This device is contraindicated in patients with active systemic infection, cryoglobulinemia, intracardiac mural thrombus, myxoma, interatrial baffle or patch.

    Warnings/Precautions

    Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular (AV) block. Immediately terminate energy delivery if partial or complete AV block is noted. Cryoablation involving coronary vessels has been associated with subsequent clinically significant arterial stenosis. Care should be taken to minimize unnecessary contact with coronary vessels during cryoablation. Endotoxins may cause pyrogenic responses in patients including inflammation and fever which can result in anaphylactic shock and death. Caution should be used with regard to endotoxins in pediatric populations as standard endotoxin limits do not differentiate between adult and pediatric populations. Ethylene oxide residuals remaining after sterilization are known to cause a potential increase in a number of biological effects including irritation, organ damage, mutagenicity and carcinogenicity. Calculations for ethylene oxide and ethylene chlorohydrin residuals indicate that the risk of these effects may be increased in patients under 3.8 kg. Avoid catheter entanglement with other catheters devices or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Do not re-use, reprocess, or resterilize this device for purpose of reuse. This device is intended only to be used once for a single patient. The use of CryoMapping mode does not prevent injuries to the patient. CryoMapping mode is used to determine if the site is appropriate for ablation. The Freezor™ catheter contains a pressurized refrigerant during operation. Release of this gas into the circulatory system due to equipment failure or misuse could result in gas embolism. Do not pull on the catheter, sheath, umbilical cables, or console while the catheter tip is frozen to the tissue, as this may lead to tissue injury. Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Do not connect the Freezor™ catheter to any radiofrequency (RF) generator or use the Freezor™ catheter to deliver RF ablation energy. Before powering up an RF generator of applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. The use of fluoroscopy during catheter ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women. Avoid positioning the catheter around the chordae tendineae, as this increases the likelihood of catheter entrapment within the heart. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue).

    Catheter handling: 

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade. 
    • Do not use excessive force to advance, withdraw, the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system. If the sterile packaging or catheter is damaged, do not use the catheter. This equipment should be used only by physicians that perform cardiac ablation. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation. Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing right-sided procedures. The Freezor™ catheter has not been evaluated for safety and compatibility in the magnetic resonance (MR) environment. Scanning a patient during the use of this device may result in patient injury.

    Potential Complications

    Potential complications that may be associated with cardiac catheterization and ablation listed alphabetically below include, but are not limited to: Access site complications including, hematoma, infection, thrombosis, ecchymosis, AV fistula, bleeding from puncture site, hemorrhage; arrhythmias (such as atrial fibrillation, atrial flutter, tachycardia); cardiac arrest and/or death; chest discomfort, pain or pressure; coronary artery spasm/stenosis; damage to heart tissue or vasculature; endocarditis; entrapment; heart block, requiring permanent pacemaker; hemothorax; infection; perforation of venous, cardiac or surrounding tissue, pericardial effusion, tamponade; pericarditis; phrenic nerve injury; pleural effusion; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary embolism; stroke; tissue infarction (such as myocardial infarction or renal infarction); thrombus; transient ischemic attack; vagal nerve injury (such as gastroparesis); vasovagal reaction.

    Perform cryoablation procedures only within the environmental parameters. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. The use of fluoroscopy during catheter ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the catheter in pregnant women. Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The safety of the catheter in the MR environment is unknown (such as any heating, migration, or image artifacts). Scanning a patient during the use of this device may result in patient injury. Avoid catheter entanglement with other catheters, devices, or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. If the device is damaged or the integrity of the sterilization barrier has been compromised, do not use the product. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system.

    The Freezor™ MAX catheter was not studied for safety of changes in anticoagulation therapy in patients with paroxysmal atrial fibrillation. This equipment should be used only by physicians that perform cryoablation procedures. Cryoablation procedures should be performed only in a fully equipped facility.

    Freezor™ Xtra cardiac cryoablation catheter

    Indications

    The Freezor™ Xtra cardiac cryoablation catheter, CryoConsole™ system, and related accessories are indicated for the cryoablation of the conducting tissues of the heart in the treatment of adult and pediatric patients over two years of age with atrioventricular nodal reentrant tachycardia (AVNRT). The Freezor™ Xtra catheter is also intended for minimally invasive cardiac surgery procedures, including surgical treatment of cardiac arrhythmias. The Freezor™ Xtra catheter freezes the target tissue and blocks the electrical conduction by creating an inflammatory response or cryonecrosis.

    Contraindications

    The Freezor™ Xtra cardiac cryoablation catheter is contraindicated in patients with the following conditions:

    • Active systemic infections
    • Cryoglobulinemia
    • Intracardiac mural thrombus
    • Myxoma
    • Interatrial baffle or patch

    Warnings/Precautions

    Do not reuse, reprocess, or resterilize this catheter for purpose of reuse. This catheter is intended only to be used once for a single patient. Closely monitor AV conduction during cryo energy delivery near the AV node due to possible risk of complete atrioventricular (AV) block. Immediately terminate energy delivery if partial or complete AV block is noted. The use of CryoMapping mode does not prevent injuries to the patient. CryoMapping mode is used to determine if the site is appropriate for ablation. The catheter contains pressurized refrigerant during operation. Release of this gas into the body or circulatory system due to equipment failure or misuse could result in gas embolism, pericardial tamponade, tissue emphysema, or other patient injury. Always advance and withdraw components slowly to minimize the vacuum created and therefore minimize the risk of air embolism. Endotoxins may cause pyrogenic responses in patients including inflammation and fever which can result in anaphylactic shock and death. Caution should be used with regard to endotoxins in pediatric populations as standard endotoxin limits do not differentiate between adult and pediatric populations. Ethylene oxide residuals remaining after sterilization are known to cause a potential increase in a number of biological effects including irritation, organ damage, mutagenicity, and carcinogenicity. Calculations for ethylene oxide and ethylene chlorohydrin residuals indicate that the risk of these effects may be increased in patients under 3.8kg. Avoid catheter entanglement with other catheters, devices, or wires. Closely monitor patients undergoing cardiac ablation procedures during the post-ablation period for clinical adverse events. Do not pull on the Freezor™ Xtra catheter, sheath, umbilical cables, or console while the catheter is frozen to the tissue, as this may lead to tissue injury. Do not connect the Freezor™ Xtra catheter to a radiofrequency (RF) generator or use it to deliver RF ablation energy. Before powering up an RF generator or applying RF energy, disconnect the cryoablation catheter from the CryoConsole™ system. The use of fluoroscopy during ablation procedures presents the potential for significant X-ray exposure to both patients and laboratory staff. Give careful consideration before using the device in pregnant women.

    Catheter handling: 

    • Use extreme care when manipulating the catheter. Lack of careful attention can result in injury such as perforation or tamponade.
    • Do not use excessive force to advance or withdraw the catheter, especially if resistance is encountered.
    • Do not use the catheter if it is kinked, damaged, or cannot be straightened.
    • Straighten the cooling segment before inserting or withdrawing the catheter.
    • Do not at any time preshape or bend the catheter shaft or cooling segment.
    • Catheter advancement should be performed under fluoroscopic guidance or other appropriate visualization technique.

    Use only isolated equipment (IEC 60601-1 Type CF equipment, or equivalent) with the CryoConsole™ system and catheters. The Freezor™ Xtra catheter has not been evaluated for safety and compatibility in the magnetic resonance (MR) environment. Scanning a patient during the use of this device may result in patient injury. The Medtronic cryoablation catheters, refrigerant tanks, and other Medtronic CryoConsole™ components should only be used with the Medtronic CryoConsole™ system. If the sterile packaging or catheter is damaged, do not use the catheter. Do not expose the catheter handle or coaxial and electrical connectors to fluids or solvents. Disconnect the catheter’s electrical connection prior to cardioversion/defibrillation. Cryoablation involving coronary vessels with liquid nitrous oxide systems has been associated with subsequent clinically significant arterial stenosis. Care should be taken to minimize unnecessary contact with coronary vessels during cryoablation.

    Avoid positioning the catheter around the chordae tendineae, as this increases the likelihood of catheter entrapment within the heart. Do not pass the catheter through a prosthetic heart valve (mechanical or tissue). Administer appropriate levels of peri-procedural anticoagulation therapy for patients undergoing endocardial right-sided procedures. This equipment should be used only by physicians that perform cardiac ablation.

    Potential Complications

    Potential complications that may be associated with cardiac catheterization and ablation listed alphabetically below include, but are not limited to: Access site complications including, hematoma, infection, thrombosis, ecchymosis, AV fistula, bleeding from puncture site, hemorrhage; arrhythmias (such as atrial fibrillation, atrial flutter, tachycardia); cardiac arrest and/or death; chest discomfort, pain or pressure; coronary artery spasm/stenosis; damage to heart tissue or vasculature; endocarditis; entrapment; heart block, requiring permanent pacemaker; hemothorax; infection; perforation of venous, cardiac or surrounding tissue, pericardial effusion, tamponade; pericarditis; phrenic nerve injury; pleural effusion; pneumothorax; pseudoaneurysm; pulmonary edema; pulmonary embolism; stroke; tissue infarction (such as myocardial infarction or renal infarction); thrombus; transient ischemic attack; vagal nerve injury (such as gastroparesis); vasovagal reaction.

    PulseSelect™ Pulsed Field Ablation System ISW

    Indications (or intended use)

    The PulseSelect™ pulsed field ablation (PFA) system is indicated for use in cardiac electrophysiological mapping (stimulation and recording) and for treatment of drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation or persistent atrial fibrillation (episode duration less than one year).

    Contraindications

    The PulseSelect™ PFA loop catheter is contraindicated for use in patients with the following conditions:

    • Active systemic infections
    • A known sensitivity to Heparin
    • Blood clotting abnormalities
    • Permanently implanted metallic objects in the left atrium

    The catheter is also contraindicated in conditions where the manipulation of the catheter within the heart would be unsafe, such as intracardiac mural thrombus.

    The catheter is not recommended for use in patients who cannot undergo standard anticoagulation protocol for a left-sided cardiac procedure, or who have had a recent coagulopathy or embolic event.

    Warnings and precautions

    To reduce the possibility of hazards associated with use of the PulseSelect™ PFA loop catheter: 

    • Use the catheter only in the recommended anatomical location.
    • Maintain the catheter position during the ablation.
    • If coughing occurs, reposition the catheter more proximally and review sedation management.
    • Ensure electrodes are not in contact with any metal during ablations (for example the guide wire).
    • Maintain substantially circular array to ensure uniform field distribution.
    • If the electrode array is deployed to deliver ablation energy, avoid continuing to move the slide control forward to prevent the guide wire lumen from coming too close to the electrode array.

    It is recommended that the array be captured while it is submerged to help reduce the possibility of air becoming entrapped around the electrode array during capture and catheter insertion.

    Catheter integrity

    Use care to avoid damage to the catheter.

    • Do not bend or kink the leading end of the catheter. Doing so could cause damage to the catheter lumen and make it unusable.
    • Monitor the catheter throughout the procedure. If a flash is observed in the luer, replace the catheter immediately.

    Electrode-electrode contact

    Avoid contact between electrodes. Contact between electrodes may create a short circuit.

    Embolism risk

    Introducing any catheter or sheath into the circulatory system entails the risk of air, gas, or thromboembolism, which can occlude vessels and lead to tissue infarction with serious consequences.

    • Avoid unnecessary catheter exchanges to minimize sheath-related embolic events.
    • Always advance and withdraw components slowly to minimize the vacuum created and the risk of air embolism.
    • Aspirate and flush the sheath frequently to help minimize the potential for embolic events resulting from the introduction of air or clot formation within the sheath.

    Fluoroscopy use during catheter placement

    Only perform catheter ablation after giving adequate attention to the potential radiation exposure associated with the procedure and taking steps to minimize this exposure. Give careful consideration before using the device in pregnant women.

    For single use only

    The PFA catheter is intended only to be used once for a single patient. Do not reuse, reprocess, or resterilize the PFA catheter.

    Careful manipulation of the catheter is necessary to avoid cardiac damage, perforation, or tamponade.

    • Do not use excessive force to advance, withdraw, or rotate the catheter, especially if resistance is encountered. Excessive force may lead to catheter damage and blood loss.
    • Use imaging guidance during catheter advancement, manipulation, and placement.
    • Vascular perforation is an inherent risk of catheter placement.
    • Performing ablation with the PFA catheter array inside the sheath may result in damage to the array or the sheath and should be avoided.
    • Performing steering manipulation with the PFA catheter array inside the sheath may result in damage to the catheter steering mechanism or the sheath and should be avoided.
    • The PFA generator is capable of delivering significant energy. Do not touch the ablation electrodes of the PFA catheter while operating the generator.
    • If the system is to be tested outside of the body, the electrode array must be immersed in saline solution in a plastic container. Never test PFA delivery in direct contact with skin.

    Use of imaging during catheter manipulation and placement is strongly advised. Manipulating the catheter without imaging may result in damage to cardiac and vascular structures.

    Other devices, wires, or catheters

    Avoid catheter entanglement with other devices, wires, or catheters, for example, intracardiac echo catheters. Failure to do so may increase the risk of entrapment of the array or damage to the array, which may affect retrieval of the device into the transseptal sheath.

    Phrenic nerve injury

    To reduce the potential for phrenic nerve injury, assess for proximity of the ablation catheter to the nerve using an appropriate technique such as pacing for local phrenic nerve capture or using the test pulse feature before ablation. Stop ablation immediately if phrenic nerve impairment is observed and assess for injury.

    Sheath and guide wire required

    Do not attempt to advance or withdraw the catheter through the vasculature without the use of a sheath and guide wire, as it may result in damage to cardiac and vascular structures.

    Implanted devices, such as pacemakers and implantable cardioverter-defibrillators (ICDs), may be adversely affected by PFA energy.

    • Keep external sources of pacing and defibrillation available during ablation.
    • Program pacemaker sensing parameters to asynchronous pacing to ensure that PFA energy is not sensed as an intrinsic event.
    • Deactivate ICD detection during the delivery of PFA energy.
    • Perform complete implantable device testing before and after ablation.
    • Monitor surface and intracardiac electrograms or vital signs during PFA energy delivery to assess for device interaction. Take appropriate action if any interaction is detected.
    • Refer to the appropriate implantable device technical manual for additional information.

    Electrical safety requirements

    The PFA generator meets the requirements of IEC 60601-1. It is the user’s responsibility after installation to verify and ensure that the generator meets the applicable local electrical safety requirements.

    Electric shock

    To avoid risk of electric shock, this equipment must only be connected to a supply main with protective earth.

    Electromagnetic interference (EMI) radiated

    The generator emits energy during ablation at a frequency level that may cause EMI with unshielded electronic equipment. To minimize EMI, the generator should be moved away from any other electronic device. If EMI is apparent during the application of energy, EMI may be reduced by repositioning the generator or other equipment.

    Electromagnetic interference (EMI) susceptibility

    The generator has been designed to minimize EMI. If interference should occur, move the generator away from the device generating the interference or place the generator at a different angle.

    Leakage current from connected devices

    Use only isolated equipment (IEC 60601-1 Type CF equipment or equivalent) with the PFA system and catheters, or patient injury or death may occur.

    Potential adverse events or potential complications

    Potential adverse events associated with cardiac catheter ablation procedures include, but are not limited to, the following conditions:

    • Access site complications (such as, bruising, ecchymosis, arteriovenous fistula, hematoma, pseudoaneurysm)
    • Anemia
