an implantable power source electrically connected to the implantable controller for supplying power to at least one of the implantable controller and the implantable electrical device, the drive MOSFET circuit being configured to at least one of a group consisting of disable a drive signal from the implantable controller and disable the routing of power from the implantable power source through the implantable controller to the implantable electrical device;

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

a cable connectible to the first side of skin button and to the implantable controller for providing electrical communication therebetween, the skin button configured as an electrical interface for at least one of the implantable controller, the implantable power source, and the implantable electrical device; and

a monitoring circuit operable to monitor a condition of power supplied by the implantable power source to at least one of the implantable controller and the implantable electrical device and operation of the implantable controller.

2. The system of claim 1 , further comprising:

the monitoring circuit operable to monitor a condition of a telemetry transmitter, the telemetry transmitter electrically connected to the monitoring circuit and configured to, transmit a transcutaneous telemetry signal representing the condition monitored by the monitoring circuit.

3. The system of claim 2 , further comprising:

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

a telemetry transceiver for wirelessly receiving the transcutaneous telemetry signal and transmitting the transcutaneous telemetry signal to a receiver associated with the backup controller, the backup controller configured to transmit a signal through the skin button to the implantable controller to at least one of disable the implantable controller and override at least one drive signal from the implantable controller to the implantable device when the transmitted transcutaneous telemetry signal received by the backup controller from the telemetry transceiver is indicative of a faulty condition of at least one of the implantable controller and the implantable electrical device.

4. The system of claim 2 , further comprising:

a power source module electrically connected to the second side of the skin button, the power source module is operable to supply power to at least one of the implantable controller and 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:

a telemetry transmitter, transmitter electrically connected to the monitoring circuit, for transmitting a telemetry signal representing the condition monitored by the monitored circuit through the skin button to a backup controller electrically connected to the second side of the percutaneous connector, the backup controller configured to transmit a signal through the skin button to the implantable controller to at least of disable the implantable controller and override at least one drive signal from the implantable controller to the implantable device when the retransmitted transcutaneous telemetry signal received by the backup controller from the telemetry transceiver is indicative of a faulty condition of at least one of the implantable controller and the implantable electrical drive.

10. The system of claim 2 , further comprising

an alarm device capable of:

receiving the transmitted transcutaneous telemetry signal; and

producing a sound alert when the received transcutaneous telemetry signal is indicative of a faulty condition of at least one of the implantable controller and the 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.
