Abstract: Medical implant which is suitable for implantation in an artificial bone bed surgically made on the outer surface of the mastoid region of the skull, having a hermetically sealed housing in which electronic components and other components or modules are accommodated. The implant housing is provided with at least on bend in at least one plane which is dimensioned such that in a plane perpendicular to the direction of the bend, a tangential line extending from a bottom portion of one housing end forms an angle, preferably an angle between 5° to 25°, with a tangent extending from a bottom portion of another housing end.

Abstract: A fixation element secures to a patient's ear an implantable microphone having a cylindrical housing part with an acoustic inlet membrane after insertion into a hole which crosses a rear bony wall of the patient's auditory canal. The fixation element has a cylindrical sleeve part which surrounds the cylindrical housing part of the microphone and which has projecting, elastic flange parts which can be placed against the side of the wall of the auditory canal which faces the skin of the auditory canal. In use, the elastic flange parts are held in a bent position against an elastic restoring force of the flange parts, before implantation, by applying a holder to the flange parts which allows insertion of the flanges through the hole of the wall of the auditory canal.
