Patent ID: 8862241

Claim:
A system for supplying energy to a medical device apparatus implanted in a mammal patient, the medical device apparatus comprising: a receiver adapted to be implanted in a mammal patient's body, the receiver being adapted to receive energy from an external energizer adapted to transmit wireless energy to said receiver to thereby supply the medical implant apparatus with energy, wherein the receiver comprises: an internal first coil that, when implanted in the patient's body, receives wireless energy for supplying energy or control signals to the medical device apparatus, when implanted in the patient's body, and wherein the system comprises: an external second coil external to the patient's body that transmits the wireless energy to the first coil, when implanted in the patient's body, adapted to receive an alternating current that flows there-through, and wherein the wireless energy received by the first coil is an alternating magnetic field, which is created by the alternating current flowing in the second coil, the external second coil windings being made of a straight wire wound around a coil center axis, the center axis being adapted to be placed perpendicular to the skin of the patient, when transmitting the wireless energy, the internal first coil being wound from wire formed into a plurality of third coils connected to one another, with the plurality of third coils connected in parallel, and wherein the internal first coil comprises a plurality of large windings, each comprising first coil windings and second coil windings perpendicular to each other, the first coil windings each having a diameter that is smaller than the second coil winding's diameter.
