US 9,526,819 B2 · Ventricular assist device controller with integrated power source

Abstract

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.

Dependent claims

An extra-corporeal controller unit for a ventricular assist device (VAD) that includes a housing having first and second battery module compartments with respective first and second battery modules adapted to provide power to the VAD, the controller unit comprising:

control circuitry configured for managing power provided from the first and second battery modules to the VAD;
first and second battery module connectors operably coupled to the control circuitry and respectively operably coupled to the first and second battery modules;
an interlocking mechanism adapted to prevent operably decoupling the first battery module connector from the first battery module if the second battery module connector is not operably coupled to the second battery module;
and
a connector adapted to operably couple the control circuitry to a percutaneous cable or a transcutaneous energy transmission (TET) unit.

2 more elements

control circuitry configured for managing power provided from the first and second battery modules to the VAD;
an energy storage unit permanently operably coupled to the control circuitry;
first and second battery module connectors respectively in the first and second battery module compartments and respectively operably coupled to the first and second battery modules, wherein each of the first and second battery module connectors is operably coupled to the control circuitry;
an interlocking mechanism adapted to prevent operably decoupling of the first battery module connector from the first battery module if the second battery module connector is not operably coupled to the second battery module;
and
a connector adapted to operably couple the control circuitry to a percutaneous cable or a transcutaneous energy transmission (TET) unit.
