Abstract
A self-cooling transcutaneous energy transfer system is provided for transmitting power to an implantable medical device, such as a defibrillator. The system includes a housing that is supported above the human body by a base so as to define a space between the housing and the body. A primary induction coil is disposed within the housing for transferring electromagnetic energy to the implantable medical device. A cooling fan is attached to the housing for providing forced convective heat transfer from the body. Various power and control circuitry are provided. The system can transfer away heat generated by eddy currents induced in the implantable device by the magnetic flux produced by the induction coil.
