Amedica Receives Patent for Ceramic-on-Ceramic Bearings

March 16, 2010
Amedica Corp. has been granted a patent covering its ceramic-on-ceramic bearings for articulating joints used for total joint replacement and spinal disc applications.

Amedica Corp., a spinal and orthopedic implant and instrument company focused on silicon nitride ceramic technologies, has been granted United States Patent No. 7,666,229, covering the company’s ceramic-on-ceramic bearings for articulating joints used for total joint replacement and spinal disc applications. Currently under development, the new 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,” said Ashok Khandkar, Ph.D., vice chairman and chief science and technology officer.

“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,” said Ben Shappley, CEO, president and director. “With this bearing technology, we expect to bring significant benefit to both patients and surgeons alike. We believe we can help surgeons achieve more successful outcomes in restoring patient function and more rapid healing for patients.”
