    Abstract: A magnetic arrangement is described for an implantable system for a recipient patient. A planar coil housing contains a signal coil for transcutaneous communication of an implant communication signal. A first attachment magnet is located within the plane of the coil housing and rotatable therein, and has a magnetic dipole parallel to the plane of the coil housing for transcutaneous magnetic interaction with a corresponding second attachment magnet.

    Abstract: An implantable magnet that can freely turn in response to an external magnetic field, thus avoiding torque and demagnetization on the implantable magnet. The implantable magnet can be combined with an electric switching function depending on the orientation of an external magnetic field, thus protecting an implanted coil and/or implant electronics against induction of over-voltage or performing an electric switching function for other various purposes. The magnetic switch may further include, for example, a first switching contact and a second switching contact. A magnetically soft body that includes an electrically conductive surface is shiftable between a first position where the body is in simultaneous contact with the first and second switching contacts, and a second position where the body is out of contact with at least one of the first and second switching contacts. The body and the implantable magnet are positioned such that the body is shifted to one of the first position and the second position as a function of the external magnetic field resulting in a magnetic force between the magnet and the magnetically soft body.

    Abstract: A surgical tool lifts an overlying layer of skin away from underlying bone to prepare the bone to accommodate a convex element of an implantable device. The tool includes a lifting shell for insertion between the skin and the bone so as to lift the skin away from bone. A tool base supports the lifting shell and is supported by the bone. A drill template opening in the tool base provides access for preparing the bone to accommodate the convex element.

    Abstract: An electromagnetic transducer includes a housing. At least one coil is associated with the housing. A spherical magnet within the housing is capable of turning in any direction and of moving along an axis. A first keeper and a second keeper are positioned on opposite sides of the magnet, both the first keeper and the second keeper including magnetically soft material and free to move along the axis. A first biasing member holds the first keeper along the axis, and a second biasing element that holds the second keeper along the axis. The first keeper and the second keeper are attracted by magnetic poles of the magnet in the absence of an external magnetic field, such that opposing magnetic poles of the magnet are aligned parallel to the axis. Alternating current flowing through the at least one coil causes a vibration of the magnet, the vibration transferred to the housing.
