1. A switched diverter circuit for minimizing heating of an implanted lead and/or providing EMI protection in a high power electromagnetic field environment, comprising:

  • an implanted lead or a leadwire;

    an energy dissipating surface associated with the implanted lead or the leadwire;

    a diversion circuit associated with the energy dissipating surface; and

    at least one switch for diverting energy in the implanted lead or the leadwire through the diversion circuit to the energy dissipating surface.
