Patent number: 9730789Abstract: A passive ossicular prosthesis has a sound-conducting prosthesis body with a first coupling element for mechanical connection to the incus, malleus, or an actuator end piece of an active hearing aid at one end. The bight is made of a strip-shaped metallic material, partially open toward the outside via a gap-type opening and is intraoperatively crimped in the middle ear for permanent attachment. There is a second coupling element at the other end of the prosthesis body for connection to a further component of the ossicular chain or directly to the inner ear. The bight includes elongated perforations with longitudinal axes extending, in the implanted state, along a curved trajectory at a right angle or slant relative to an axis parallel to the longitudinal axis (a) of the enclosed object to reduce spring action and stiffness and markedly reduce the force to be applied for the crimping.Type: GrantFiled: March 27, 2015Date of Patent: August 15, 2017Assignee: Heinz Kurz GmbH MedizintechnikInventors: Jack M. Kartush, Uwe Steinhardt, Heinz Kurz

Patent number: 9259311Abstract: An ossicular prosthesis formed as a sound-conducting, elongated prosthesis body has a first coupling element designed as a tympanic membrane top plate or a clip or a connecting piece to an actuator end piece of an active hearing implant and a second coupling element provided with an access opening into a receiving space designed as a bell or a clip for a mechanical connection of the prosthesis to the head of the stapes. The second coupling element has a backing section on an inner surface of the receiving space as an axial extension of the prosthesis body. The backing section protrudes from the prosthesis body into the receiving space. In an implanted state, the backing section bears against a head of the stapes and prevents a formation of a hollow space between the stapes and an inner surface of the receiving space in an axial extension of the elongated prosthesis body.Type: GrantFiled: April 7, 2014Date of Patent: February 16, 2016Assignee: Heinz Kurz GmbH MedizintechnikInventors: Uwe Steinhardt, Seilesh Babu, Heinz Kurz
