Abstract
A mechanism for transferring energy from an external power source to an implantable medical device is disclosed. An antenna is positioned in proximity of the implantable medical device. The position of a core of the antenna is adjusted relative to the implantable medical device while the antenna is maintained substantially stationary. A frequency of transmission of a power source is adjusted, and the antenna is driven at the adjusted frequency to transfer energy transcutaneously to the implantable medical device. In one embodiment, the frequency of transmission is selected based on an amplitude of a signal in the antenna.
