Affinity Venous Air Removal Device (VARD)
No intervention required; automated venous air removal facilitating the benefits of closed circuits.
Overview
Experience automatic venous air removal with the Medtronic Affinity® VARD. A visual and audible alarm alerts the surgical team to the condition, as it automatically and quickly removes air in the extracorporeal circuit.
The system features:
- Ultrasonic air sensors that detect air at the inlet of the system as well as the liquid level in the filter.
- A 38 micron screen.
- Chamber and port at the top of the device to collect and remove coalesced air.
If air enters the Affinity VARD through the venous return line and the liquid level drops below sensor level, the sensor will provide a signal to the connected AAR1000 that in turn automatically opens the pinch valve* to the vacuum. The vacuum will suction the air out of the Affinity VARD until the sensor detects liquid. The AAR1000 Controller then reengages the pinch valve and closes the vent tube. This means you can be assured that the Affinity VARD will detect air, while the AAR100 Controller will automatically control your vacuum activity to remove any air detected.
Using the Affinity VARD gives you the ultimate flexibility to include or eliminate a venous hardshell reservoir, cardiotomy or holding bag, depending on your circuit setup preference.
Affinity VARD is coated with Cortiva™ BioActive Surface only as part of a Medtronic Perfusion Systems custom pack.
*The pinch valve responds to full open position within 0.1 seconds for immediate air removal
This addition to the Affinity® family is part of Medtronic’s commitment to providing more options for patients undergoing cardiopulmonary bypass.
