Abstract

A compact implantable controller and battery module for a transcutaneous energy transfer (TET) system is provided having a single biocompatible housing encasing an energy storage device, a power control module, and a device control module. The power control module controls energy transfer to the storage device during charging and monitors power consumption of a cardiac assist device. The device control module controls and monitors the operation of a cardiac assist device.

Claims

1. An implantable controller for controlling a cardiac assist device, comprising:

a single biocompatible housing encasing;

an energy storage device (a rechargeable battery pack);

a power control module for controlling energy transfer to the storage device during charging and for monitoring power consumption during use of the cardiac assist device; and

a device control module for controlling and monitoring the operation of a cardiac assist device.

2. The controller of claim 1, wherein the controller further comprises a communications module for transmitting information to external diagnostic or control equipment.

3. The controller of claim 1, wherein the controller further comprises a microprocessor for controlling the power control module and device control module.

4. The controller of claim 1, wherein the controller further comprises an interface for connecting one or more coils adapted for disposition in a patient and configured to produce electric current in the presence of a time-varying magnetic field.

5. The controller of claim 4, wherein the interface comprises a glass-to-metal hermetic connector for connecting to the one or more coils.

6. The controller of claim 1, wherein the housing is formed from any of titanium, stainless steel, epoxy, plastic, ceramic, glass, or polyurethane.

7. The controller of claim 1, wherein the housing includes large-radius corners and edges configured to prevent tissue necrosis when implanted in a patient.
