Abstract
External power source, charger, system and method for transcutaneous energy transfer. An implantable medical device has a first housing having operational componentry for providing the therapeutic output. A secondary housing is mechanically coupled to the first housing having a secondary coil operatively coupled to the componentry, the secondary coil capable of receiving energy from the external source. A magnetically shielding material is positioned between the secondary coil and the first housing. An external power source has an external housing. A primary coil carried in the external housing, the primary coil being capable of inductively energizing the secondary coil when the housing is externally placed in proximity of the secondary coil with a first surface of the housing positioned closest to the secondary coil, the first surface of the housing being thermally conductive surface. An energy absorptive material carried within the external housing.
