Abstract
An implantable transcutaneous energy transfer device secondary coil module includes a housing, a secondary coil, power conditioning circuitry, and a low voltage, high power connector. The transcutaneous energy transfer secondary coil is disposed outside the housing and is configured to receive a time-varying magnetic field provided by a transcutaneous energy transfer primary coil, and to convert the time-varying magnetic field into a high voltage, alternating current electric signal within the coil. The power conditioning circuitry is mounted within the housing and is electrically coupled to the secondary coil. The power conditioning circuitry including electronics for converting the high voltage, alternating current electric signal from the secondary coil into a high power, low voltage direct current electric signal. The low voltage, high power connector electrically coupled to the power conditioning circuitry and extending outside the housing for connecting the secondary coil module to a power bus for delivering power to implanted devices.
