Increase in Temperature from AIMDs Dissipating Endogenous Heat

Active Implantable Medical Devices generate heat as a result of resistive losses in their circuitry, exothermic reaction in their batteries, eddy-current heating due to inductive recharge, friction between mechanical components, etc.  The European Standard which regulates AIMDs limits the heating of the outer surface of an AIMD to 2ºC above normal body temperature.  Despite the
