Levacor VAD
How it Works
Like the current Novacor® LVAS, the Levacor VAD is implanted within the abdomen. Blood enters the pump through an inflow conduit connected to the recipient's left ventricle. The pump then ejects blood through an outflow conduit into the arterial system, thereby supporting the systemic circulation. The physiologic control system, currently under development, will allow the device to be self-regulating, automatically adjusting the rotor speed in response to the recipient's changing circulatory requirements.
In the initial configuration shown, a percutaneous (through the skin) lead will connect the implanted pump to an external controller and rechargeable power pack. This represents the simplest system with the fewest implanted components. Ultimately, the system could be made available in a fully implantable configuration, in which the controller and a standby battery pack are implanted. A transcutaneous (across the skin) energy transfer system (TETs) would conduct power from an external battery pack to the implanted system.
Availability
Levacor VAD is not currently available. It began a clinical feasibility trial in March 2006.
