Implantable device with a charging current feed arrangement which has a receiving coil
First Claim
1. Implantable device with a charging current feed arrangement comprising:
- at least one receiving coil into which, in an implanted state within a body, energy can be transcutaneously fed electromagnetically via a charging device located externally of the body;
a repeatedly rechargeable electrochemical battery; and
a main module connected to the battery to receive electric power therefrom, and having a housing arrangement made of a biocompatible metal;
wherein the receiving coil is located outside of the housing arrangement and being electrically coupled to the parts of the implantable device located within the housing arrangement;
wherein the receiving coil is wound from at least one metallic conductor that is jacketed with an electrically insulating material and is surrounded by a biocompatible polymer; and
wherein the receiving coil is mechanically connected to at least a part of the housing arrangement to form a unit therewith.

Abstract
Implantable device with a charging current feed arrangement (78) which has at least one receiving coil (106) into which energy can be fed electromagnetically via a charging device (59) located outside the body, an electrochemical battery (90) which can be repeatedly recharged via the charging current feed arrangement, and with a main module (56, 130) supplied with electric power by the battery. The components of the implantable device (54), with the exception of the receiving coil, are accommodated in a housing arrangement (72, 72'"'"', 72", 128, 132) of biocompatible metal. The receiving coil (106) is wound from at least one metallic conductor (109) that is jacketed with an electrically insulating material (11), is surrounded by a biocompatible polymer (104) and also is mechanically connected to at least part of the housing arrangement (72, 72'"'"', 72", 128, 132).
