Amedica Corporation announced in a press release that it has been granted United States Patent No. 7,666,229 for its novel ceramic-on-ceramic bearings for articulating joints used for total joint replacement and spinal disc applications. Currently under development, Amedica’s new advance bearing surfaces covered under this and other pending patents will be used as ultra-low-wear bearing components for motion preserving implants.

“The combination of high strength and toughness of our silicon nitride ceramics provides us with a unique and versatile surface-bearing technology, which offers surgeons wider design choices and better anatomic fit and function compared to currently available alternate bearing options,” stated Ashok Khandkar, PhD., vice chairman and chief science and technology officer of Amedica Corporation, in the release.

“The bearing technology and range of applications covered by this patent and other issued and pending patents represent a major advance in orthopedic implants and other applications,” Ben Shappley, CEO, president and director for Amedica Corporation, noted. “With this bearing technology, we expect to bring significant benefit to both patients and surgeons alike.
