1. An implantable assembly adapted to be disposed within a living organism, comprising:

  • a thermoelectric module to convert thermal energy to electrical energy; and

    a pair of conductive leads, operatively connected to said thermoelectric module, for conducting said electrical energy from said thermoelectric module; and

    an implantable device receiving said electrical energy;

    said thermoelectric module including,a first L-shaped plate having a first surface and a second surface,a second L-shaped plate having a first surface and a second surface,a first insulating material substantially covering said first L-shaped plate, except said first surface and said second surface thereof,a second insulating material substantially covering said second L-shaped plate, except said first surface and said second surface thereof, andthermoelectric elements disposed between said second surface of said first L-shaped plate and said second surface of said second L-shaped plate;

    said first L-shaped plate and said second L-shaped plate transferring thermal energy;

    said thermoelectric elements converting thermal energy to electrical energy.
