Hard-wired implanted controller system

1. A circulatory assist system comprising:

an implantable electrical device having an electric motor;

an implantable controller electrically connected to said implantable electrical device;

an implantable power source electrically connected to said implantable controller for supplying power to the implantable controller or to the implantable electrical device; and

a skin button having a first side and a second side opposite to said first side;

wherein said implantable controller is attachable to said first side of the skin button,

the second side of said skin button allows connectivity to said implantable controller,

wherein the implantable controller includes a drive MOSFET circuit for disabling drive signals from the implantable controller or disabling routing of power from the implantable power source through the implantable controller to the implantable electrical device, and

wherein the skin button is configured to selectively ground an input MOSFET disable signal.

2. The system of claim 1 , further comprising:

a monitoring circuit operable to monitor a condition of power supplied by said implantable power source to said implantable controller or to said implantable electrical device, or operation of the implantable controller, and a telemetry transmitter, electrically connected to said monitoring circuit, for transmitting a transcutaneous telemetry signal representing the monitored condition.

3. The system of claim 2 , further comprising:

a backup controller electrically connected to said second side of the skin button;

a telemetry transceiver, for wirelessly receiving said transcutaneous telemetry signal and retransmitting the signal to a receiver associated with the backup controller;

wherein said backup controller is capable of transmitting through the skin button to said implantable controller a signal to disable said implantable controller or to override drive signals from said implantable controller to said implantable device when said retransmitted transcutaneous telemetry signal received by said backup controller from said telemetry transceiver is indicative of a faulty condition of said implantable controller or said implantable electrical device.

4. The system of claim 2 , further comprising:

a power source module electrically connected to said second side of the skin button;

wherein said power source module is operable to supply power to the implantable controller or to the implantable electrical device through the skin button.

5. The system of claim 1 , further comprising:

a monitoring circuit operable to monitor a condition of:

power supplied by said implantable power source to said implantable controller or to said implantable electrical device, or operation of the implantable controller, and

a telemetry transmitter, electrically connected to said monitoring circuit, for transmitting a telemetry signal representing through the skin button the monitored condition to a backup controller electrically connected to said second side of the skin button;

wherein said backup controller is capable of transmitting through the skin button to said implantable controller a signal to disable said implantable controller or to override drive signals from said implantable controller to said implantable device when said retransmitted transcutaneous telemetry signal received by said backup controller from said telemetry transceiver is indicative of a faulty condition of said implantable controller or said implantable electrical device.

6. The system of claim 1 , wherein the implantable power source includes a rechargeable battery.

7. The system of claim 1 , wherein the implantable electrical device includes a motor and the implantable controller includes a DC motor control circuit for controlling said motor.

8. The system of claim 1 , wherein the implantable controller and the implantable power source are implanted inside a patient's body.

9. The system of claim 2 , wherein the monitoring circuit and the telemetry transmitter are implanted inside a patient's body.

10. The system of claim 2 , further comprising an alarm device capable of:

receiving said transmitted transcutaneous telemetry signal;

and producing a sound alert when said received signal is indicative of a faulty condition of said implantable controller or said implantable electrical device.

11. The system of claim 10 , wherein said alarm device is embodied in a wrist watch.

12. The system of claim 3 , further comprising a power source connected to the backup controller.
