Patent ID: 8489200

Claim:
An implantable transcutaneous energy transfer device secondary coil module for receiving and conditioning power from a time-varying magnetic field provided by a transcutaneous energy transfer primary coil, comprising: an inner housing having an inductive heat reducing means comprising a magnetically permeable material; a transcutaneous energy transfer secondary coil disposed outside of and surrounding the housing configured to receive the time-varying magnetic field provided by the transcutaneous energy transfer primary coil and convert the time-varying magnetic field into a high voltage, alternating current electric signal within the coil; power conditioning circuitry mounted within the housing and electrically coupled to the secondary coil, the power conditioning circuitry including electronics for converting the alternating current electric signal from the secondary coil having a high voltage greater than or equal to about 200 volts into a direct current electric signal having a low voltage of less than or equal to about 50 volts and a high power level of greater than or equal to about 15 watts; a low voltage, high power output means electrically coupled to the power conditioning circuitry and accessible from outside the module for connecting the secondary coil module to a power bus for delivering power to implanted devices.
