VENTRICULAR ASSIST DEVICE CONTROLLER WITH INTEGRATED POWER SOURCE

摘要

An extra-corporeal controller unit for an implantable ventricular assist device (VAD) includes control circuitry integrated with a rechargeable power source without including any power cables between the control circuitry and the rechargeable power source. The rechargeable power source includes two or more rechargeable batteries configured in respective battery modules. The battery modules are configured for removable installation in a housing of the controller unit. Mating power connectors are integrated in the battery modules and the housing. The mating connectors are configured to couple each battery to the control circuitry whenever the respective battery module containing the battery is installed in the housing. An energy storage unit may be permanently included in the controller unit and configured to remain fully charged and provide power to the VAD when the battery modules are removed.

主权项

1. An ventricular assist device (VAD) system, comprising:
an extra-corporeal controller unit housing including two or more battery module compartments; control circuitry configured in the controller unit housing for power management and VAD system monitoring and control; a first battery module connector in each of the battery module compartments, the battery module connectors coupled to the control circuitry; a connector on the housing, the connector configured for coupling the control circuitry to a percutaneous cable or a transcutaneous energy transmission (TET) unit of a ventricular assist device; and a ventricular assist device coupled to the percutaneous cable or the TET unit.
