Walter Baumgartner: Artificial intervertebral disk member. SULZER Medizinaltechnik, Townsend and Townsend Khourie and Crew, December 6, 1994: US05370697 (687 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 ...

Otto Frey, Rudolf Koch, Heinrich M F Planck: Joint endoprosthesis. Sulzer Brothers, Kenyon & Kenyon, June 12, 1990: US04932969 (446 worldwide citation)

The joint endoprosthesis is formed of a compressible elastic hollow body which is disposed between two anchoring elements. The hollow body defines a closed cavity which is filled with an incompressible fluid medium. Compressive loadings near the edges of the endoprosthesis cause a displacement of th ...

Otto Frey, Rudolf Koch: Intervertebral prosthesis. Sulzer Brothers, Kenyon & Kenyon, April 17, 1990: US04917704 (349 worldwide citation)

The intervertebral prosthesis provides a replacement for a damaged disk. The prosthesis is formed as a solid body of kidney-shape and is provided with a metal mesh covering for the ingrowth of tissue. Raised parts are formed on the opposite surfaces of the kidney-shaped body impart lateral stability ...
