Amedica Receives Patents for Disc Implant

September 27, 2010

Amedica Corp. has been granted two U.S. patents for its total disc replacement (TDR) technology, which features the use of silicon nitride in the construction of the complete implant. U.S. patent nos. 7,758,646 B2 and 7,771,481 B2 cover the disc’s design and the use of the silicon nitride ceramic materials in its construction.

The TDR is created exclusively from silicon nitride; no other materials are used in the design. A motion-preserving total disc replacement implant, the TDR is designed to maintain a full range of natural motion following implantation while providing resistance to extreme rotation of the spine. Its construction features a polished bearing surface on one side and a porous bio-in-growth surface on the reverse side for solid endplate attachment.

The exclusive use of silicon nitride technology in the development of the TDR furthers the benefits of silicon nitride to both surgeons and patients and reinforces the increasing importance of the technology in the growing spine and reconstructive implant orthopaedics market, according to Ben Shappley, CEO, president and director.

“Using silicon nitride technology in the construction of the entire implant is a major breakthrough for spinal devices,” said Shappley. “With the use of silicon nitride and its remarkable strength and wear characteristics, surgeons are able to avoid the problems and degenerative conditions associated with implant devices using older technologies. This allows surgeons to achieve more successful outcomes in restoring patient function and provides patients with lifetime relief that returns them to an active lifestyle.”
