Abstract
A mechanical coupling for an output-side driver of an active or passive implantable hearing system. The driver is adapted to vibrate a preselected coupling site on an ossicular chain via a first coupling which has a coupling rod which can be caused to vibrate mechanically by the driver and a coupling element which can be connected to the preselected coupling site. The coupling rod and the coupling element are interconnected by at least one coupling. A first coupling half of the coupling has an approximately spherical outside contour which can be accommodated in the inside contour of a second coupling half, i.e. a contour which is at least partially complementary to the outside contour. The is adapted to reversibly swivel and/or turn against friction forces, but is essentially rigid under the dynamic forces which occur in the implanted state.
