Superficial vein
ClosureFast™ radiofrequency ablation (RFA) system
<p>The ClosureFast™ procedure uses radiofrequency energy to treat patients with superficial vein disease.</p>
Overview
Data are from ClosureFast™ 7F studies. ClosureFast™ 6F catheter is designed to provide the same outcomes as established by ClosureFast™ 7F catheter.

Deliver lasting results with gap-free thermal ablation
The ClosureFast™ procedure features a patented overlap of 0.5 cm at each thermal treatment segment, eliminating gaps between segments ― for lasting vein closure.1,3
6F profile, 8 cm heating length
1. 8 cm ablation
2. 0.5 cm overlap
3. 8 cm ablation
Note: 3 cm (7F) heating length available for shorter segments.
Data are from ClosureFast™ 7F studies. ClosureFast™ 6F catheter is designed to provide the same outcomes as established by ClosureFast™ 7F catheter.
Indications
The ClosureFast™ radiofrequency ablation catheter is intended for endovascular coagulation of blood vessels in patients with superficial vein reflux.
ClosureFast™ radiofrequency ablation catheter
- The ClosureFast™ radiofrequency ablation catheter precisely heats an 8 cm vein segment (or 3 cm for shorter, refluxing vein lengths) in one 20-second interval.
- The heat provided by the catheter shrinks and collapses the target vein, creating a fibrotic seal and occluding the vessel.
ClosureFast™ radiofrequency stylet
- The ClosureRFS™ radiofrequency stylet is an intravascular ablation device specifically intended for the treatment of incompetent perforator and tributary veins.
- This minimally invasive outpatient procedure leaves minimal scarring at the puncture site and can be either the primary treatment or an adjunct treatment using the ClosureFast™ radiofrequency ablation catheter.
ClosureFast™ radiofrequency generator
- The ClosureRFG™ generator delivers radiofrequency energy to the ClosureFast™ radiofrequency ablation catheter and the ClosureRFS™ radiofrequency stylet for the effective treatment of CVI.
- The controlled feedback mechanism monitors intravascular heat parameters in real time to automatically regulate therapeutic power.
Adverse events may include hematoma, phlebitis, skin injury, nerve injury, thrombophlebitis, thrombosis, and/or pulmonary embolism.
