Abstract
Implantable arrangement for mechanical coupling of an output-side driver part of an active or passive hearing system, the driver part having a capacity to be excited to mechanical vibrations, to a preselected coupling site on the ossicular chain, the footplate of the stapes or a membrane which closes the round window or an artificial window in the cochlea, in the vestibulum or in the labyrinth (equilibrium organ), via a coupling arrangement which has a coupling element adapted to be connected to a preselected coupling site. The coupling element is provided with a positioning device for selective movement of the coupling element between an open position in which the coupling element is adapted to be engaged with and disengaged from the coupling site, and a closed position in which the coupling element in the implanted state is joined by force fit and/or form fit to the coupling site.
