Claim:
1. An operation method for implanting a medical device being part of a system for supplying energy to the medical device when implanted, the medical device comprising: i. an internal charger comprising a first coil, the internal charger adapted to; receive wireless energy from an external charger having a second coil arranged to wirelessly transmit energy with an electromagnetic field to supply the internal charger with energy and arranged to regulate the wirelessly transmitted energy based on feedback information from the internal charger, to charge an internal power supply wirelessly, ii. a wireless passive feedback system, adapted to; transmit feedback information from the internal charger to the external charger, adapted to be powered by a wireless signal transmitted by the external charger and having the feedback information based on information obtained from at least one radio frequency identification (RFID) transmitter included in the wireless passive feedback system having an RFID signature adapted to be set in response to a magnitude of the electromagnetic field received, iii. a measurement unit, adapted to; actively measure an electric parameter to provide to the at least one RFID transmitter with a determined value related to the magnitude of the received electromagnetic field and wherein the at least one RFID transmitter is adapted to set and change its identification according to the determined value and to be passively powered by the wireless energy, wherein the operation method comprising the steps of: creating an opening in the skin of the patient, dissecting an area of the patient, placing the medical device in the dissected area, and wherein the system is adapted to receive wireless feedback information from the internal charger transmitted out of the patient's body as a signal containing the RFID identification, when being charged with wireless energy.
