Walter Baumgartner: Artificial intervertebral disk member. SULZER Medizinaltechnik, Townsend and Townsend Khourie and Crew, December 6, 1994: US05370697 (676 worldwide citation)

The artificial intervertebral disk member (1) consists of an upper (2) and a lower (3) support, which are attached in the adjacent vertebrae (32, 33), and of an elastic separator (4). The separator is constructed as a separate insert part (5), which can be inserted from outside into the final positi ...

Walter Baumgartner: Intervertebral prosthesis. Sulzer Brothers, Kenyon & Kenyon, December 15, 1992: US05171280 (444 worldwide citation)

The prosthesis has a valve at one end formed of a fixed base and a coiler body which is able to rotate on the base. A flexible elastic body defining a hollow chamber extends from the coiler body and is able to receive filling medium via the valve. A compact strand extends from the free end of the el ...
