Abstract: The invention relates to a golf putter with a club head (1), a shaft (2) attached in the club head (2) and a handle and is characterized in that the club head (1) is formed of a transparent material. The transparency is present between the hitting side (3) of the club head (1) and the rear side (4) of the club head (1), which is opposite to the hitting side.

Abstract: An auditory ossicle prosthesis (10) which is fastened to the limb of incus (20) of the human ossicular chain and to the stapes, or is inserted directly into the inner ear, whereby the auditory ossicle prosthesis (10) is made of an elastic material or a material having at least one hinged connection, and whereby the auditory ossicle prosthesis (10), starting at its articulation on the limb of incus (20), largely traces the course of the natural limb of incus (20) to its end or past it, and, angled downward in the region of the level of the natural end of the limb of incus (20), extends to the other endpoint of the auditory ossicle prosthesis (10) on the stapes or at/in the inner ear.

Abstract: An auditory ossicles prosthesis mountable with its one end on a hammer grip of a human auditory ossicies chain and with its another end on a raising bracket of the human auditory ossicles chain or insertable directly into an inner ear, wherein the auditory ossicles prosthesis has a prosthesis element, and an at least one joint integrated in the prosthesis element.

Abstract: The hearing aid comprises a external microphone, amplifier and battery assembly transmitting its signals to a transducer structure arranged on the squama temporalis. A transducer in the transducer structure generates oscillating motions that are transferred to a vibration transmitter arranged in a groove extending along the bony external auditory canal wall. A clip at the distal end of the vibration transmitter is coupled to the long process of the incus. The hearing aid is easy to implant and provides efficient coupling of the mechanical oscillations to the ossicles of the middle ear.
