Abstract
A medical device adapted for implantation into a patient receives electrical power from an extracorporeal power supply. The medical device has a first receiver for a first wireless signal, a power circuit that extracts energy from the first wireless signal to power the medical device, and a feedback signal generator that transmits a second wireless signal indicating a magnitude of energy extracted from the first wireless signal. The extracorporeal power supply includes a source of electrical power and a power transmitter that emits the first wireless signal. A second receiver enables the extracorporeal power supply to receive the second wireless signal. A feedback controller manipulates the first wireless signal in response to the second wireless signal to ensure that sufficient electrical energy is provided to the medical device without wasting electrical power from the source.
