1. An implantable medical device that communicates with a primary transcutaneous energy transfer (TET) circuit external to a patient via a transcutaneous energy transfer channel, the implantable medical device comprising:

  • a housinga first TET coil received by the housing;

    a second TET coil received by the housing, electrically coupled in parallel with the first TET coil, and physically proximate to and centered on a longitudinal axis of the first TET coil; and

    control circuitry in electronic communication with the parallel first and second TET coils and operably configured to utilize power transferred to the first and second TET coils.
