Abstract

The present invention relates to at least partially implantable devices such as partly implantable hearing devices, for example cochlear implants, and specifically, to implantable magnets for interaction with external magnets in such devices. Embodiments of the present invention are directed to a magnet arrangement for a hearing implant device. An implant device contains signal processing circuitry configured for receiving an implant communications signal transmitted from an external transmitting coil through overlying skin of an implanted patient, and the implant device includes an outermost surface adapted to lie between the overlying skin and underlying skull bone of the implanted patient. There is a magnet case within the implant device, and the magnet case is configured to be rotatable about a case rotation axis which is at least approximately perpendicular to said outermost surface of the implant device. An implant magnet arrangement is located within the magnet case and configured to cooperate with a corresponding external holding magnet in an external device located over the overlying skin to magnetically hold the external device against the overlying skin.
