Abstract

A system for supplying energy to a medical device implanted in a mammal patient. The system comprises an external energy source adapted to be externally arranged to the patient'"'"'s body and configured to wirelessly transmit energy for powering the medical device. The system further comprises an internal energy receiver adapted to be implanted in the patient'"'"'s body and configured to receive energy, transmitted from the external energy source, for supplying energy or control signals to the medical device, and a control unit configured to control the amount of energy received by the internal energy receiver, wherein said control unit is configured to control based on a parameter indicating a characteristic of the medical device or a characteristic of the patient'"'"'s condition.

Claims
