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).
