Arrangement for mechanical coupling of a driver to a coupling site of the ossicular chain

Implantable arrangement for mechanical coupling of a mechanically vibratable output-side driver part of a hearing system to a preselected coupling site selected from the group consisting of the ossicle chain, the, footplate of the stapes the membrane which closes the round window, an artificial window in the cochlea, in the vestibulum and in the labyrinth of a patient via a coupling arrangement, said coupling arrangement being connectable to said preselected coupling site and comprising, at least two coupling elements connected in a predetermined, spaced apart position relative to each other when disengaged from the preselected coupling site and an actuating device for selective movement of at least one of the coupling elements relative to the other coupling element between an open position in which the coupling arrangement is engageable on and disengageable from the preselected coupling site, and a closed position in which the coupling arrangement, in an implanted state, is joined to the preselected coupling site.
