Device for electromechanical stimulation and testing of the hearing, including an electromechanical transducer for producing mechanical vibrations, a mechanical coupling element for transmitting mechanical stimulation vibrations from the electromechanical transducer without surgery through the external auditory canal to the umbo, and thus, to the manubrium malleli of the ossicular chain, a positioning device for positioning the coupling element with reference to the umbo, and a fixing device for secure, play-free linkage of the positioning device to human body, especially the human skull. An intermediate element is provided between the positioning device and the electromechanical transducer, said intermediate element being designed and dimensioned such that the intermediate element transmits quasi-steady-state positioning adjustments from the positioning device to the transducer, but reduces transmission of at least dynamic forces from the positioning device to the coupling element at least to such an extent that the risk of middle or inner ear damage is substantially reduced.

Device for electromechanical stimulation and testing of hearing

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&deg; to 25&deg;, with a tangent extending from a bottom portion of another housing end.

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. After the microphone assembly has been inserted through the hole, the holder (which can be, for example, thread or a cap) is removed allowing the elastic flange parts to spring into a position in which they project essentially radially away from the cylindrical sleeve part between the wall of the auditory canal which faces skin of the auditory canal and the skin of the auditory canal.
