Abstract
A device for supplying energy to a medical device is disclosed, comprising an external energy source, an external control unit, an external signal receiver, and a coil displacement unit connected to the external control unit and configured to adjust an energy transfer efficiency by repeatedly adjusting a position of a primary coil relative to a secondary coil by displacing the primary coil relative to the secondary coil in a plurality of different directions.
Claims22
A device for supplying energy to an electrically operable medical device implanted in a patient, said device comprising:
- an external energy source located outside of the patient, the external energy source being arranged to transfer energy inductively from a primary coil in said external energy source to a secondary coil in an internal energy receiver located inside the patient and being connected to said medical device;
- an external control unit arranged to, in response to a control signal, accurately control the amount of transferred energy to the implanted medical device, by adjusting the energy transfer efficiency from said external energy source to said internal energy receiver;
- an external signal receiver connected to the external control unit, the external signal receiver being arranged to receive a control signal reflecting a determined required amount of energy;
- and
- a coil displacement unit connected to said external control unit and configured to adjust the energy transfer efficiency by repeatedly adjusting the position of said primary coil relative to said secondary coil by displacing the primary coil relative to said secondary coil in a plurality of different directions.
