Incorporation of an in-line filter for ultrafiltration or hemodialysis to the abiomed BVS5000 ventricular assist device

Multiple organ system dysfunction is an associated finding in patients requiring acute ventricular assist device (VAD) support. In the setting of acute renal failure, percutaneous catheters are placed for hemodialysis and/or ultrafiltration. Incorporation of an ultrafiltration or hemodialysis system in the Abiomed BVS5000 ™ VAD circuit is a simple maneuver that eliminates the need for an additional catheter, thereby reducing the vascular and infectious complications associated with these catheters. We recommend splicing connectors into the outflow tubing of the right VAD circuit for attachment to an ultrafiltration or hemodialysis unit. This technique is a safe, simple, and reliable method by which to perform intermittent or continuous ultrafiltration or hemodialysis.
