1. A system, comprising:

  • an implantable medical device comprising a secondary coil; and

    an external device comprising;

    a primary coil adapted to be transcutaneously coupled to the secondary coil to transfer energy to the implantable medical device;

    a housing having a side adapted to be positioned in proximity to the secondary coil when the primary coil is transcutaneously coupled to the secondary coil;

    a temperature sensor adapted to provide an output indicative of a temperature of the side of the housing; and

    control circuitry adapted to control the transfer of energy to the implantable medical device based on the output of the temperature sensor to limit a temperature to which a patient is exposed during the transfer of energy to the implantable medical device.
