Abstract: A middle ear prosthesis (40) is provided for mounting in the middle ear (4). The middle ear prosthesis comprises a shaft (42) having a distal end configured for the introduction into the inner ear (8) through an aperture (30) formed in a footplate (23) of a stapes bone and in a membrane of an oval window of the inner ear, by moving the shaft in an introduction direction, the shaft being configured for transmitting sound wave vibrations to the inner ear. The prosthesis further comprises a coupling portion (46), for coupling, the shaft to at least one of the ossicles (17) so as to allow transmitting thereby sound wave vibrations from the ossicles to the shaft; and a stop member (48) spaced from the distal end of the shaft and configured for bearing against the remaining portions thereby limiting the movement of the shaft in the introduction direction.
