Abstract:
Embodiments of the present invention are directed to an implantable hearing implant, such as cochlear implants. The implantable hearing implant includes an implant device containing signal processing circuitry configured to receive an implant communications signal transmitted from an external transmitting coil. The implantable hearing implant further includes an implant magnet 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. The implant magnet has a north magnetic pole, a south magnetic pole, and as a whole has an overall magnetic dipole moment that is parallel to or at an angle of 30° or less with respect to the outermost surface. The implant magnet has a north end portion and a south end portion, each having an individual magnetic dipole moment that is inclined with respect to the overall magnetic dipole moment.
