Abstract
Techniques are disclosed for controlling the transcutaneously transfer of energy to an implantable medical device (IMD) that is in proximity to a conductive object that conducts current in the presence of an electromagnetic field. Various techniques are disclosed for estimating or determining the levels of heat dissipation associated with the object during the transfer of energy. If too much heat is being dissipated, the transfer of energy may be adjusted so that heating remains below acceptable levels.
