Abstract: The invention proposes pre-load a ball joint (4) of an auditory ossicle prosthesis (1) with a disk-shaped pre-loading element (11) in a longitudinal direction of a shaft (7) of the auditory ossicle prosthesis (1), whereby an almost loss-free vibration transmission is achieved.

Abstract: The invention proposes forming an auditory ossicle prosthesis (1) in one piece from sheet metal, like pliers, with two congruent clamps (3), which can be opened and closed with a two-part head element (2), the head parts (4) of which act as pliers handles. The auditory ossicle prosthesis (1) can be clamped onto an auditory ossicle without exerting any force on the auditory ossicle.

Abstract: A length-adjustable ossicular prosthesis, includes a cylindrical pin serving as a connecting element, which connects a foot element to a head element. The head element is intended to be disposed on an inside of an eardrum, and the foot element is intended to be attached to an anvil in a human ear. The head element is designed as an elliptical ring having an opening, which can be closed by closing a locking mechanism comprising a hook. Two guiding and clamping elements project inwardly from the ring, between which, in an open position, the connecting element is displaceably guided, and which secure the head element non-displaceably and non-rotatably on the connecting element when the ring is closed, and as a result the guiding and clamping elements are tensioned against the connecting element.

Abstract: A middle ear prosthesis is made of a stiff deformable material and includes a planar head end with a central portion having a central diameter. The head end is adapted for engagement with a tympanic membrane from the middle ear of an implanted patient. An opposing pair of U-shaped stapes engagement legs bend down from the central portion so that an end distance between ends of the engagement legs is less than the central diameter. The engagement legs are adapted for adjustable length engagement with the stapes in the middle ear of the implanted patient. The head end and the engagement legs are adapted to transmit vibrations from the tympanic membrane to the stapes for perception as sound by the implanted patient.
