Osteotech Receives Its Second FDA Clearance For Its New GraftCage(TM) Product Line, The GraftCage(TM) TLX System

EATONTOWN, N.J., Dec. 20 /PRNewswire-FirstCall/ -- Osteotech, Inc. announced today that the Food and Drug Administration ("FDA") has cleared its 510(k) application for the GraftCage(TM) TLX System, the second approval for Osteotech's GraftCage(TM) Product Line in the last two weeks. The GraftCage(TM) TLX, along with the GraftCage(TM) ACX, is manufactured from Invibio's PEEK-OPTIMA(R) polymer.

Sam Owusu-Akyaw, Osteotech's President and Chief Operating Officer, stated, "We now have FDA clearance to distribute two different products in our GraftCage(TM) Product Line, the GraftCage(TM) ACX and GraftCage(TM) TLX, both of which we anticipate distributing in the first quarter of 2006. These two new products, along with additional GraftCage(TM) Product Line extensions we expect to introduce in 2006, will allow Osteotech to compete in that portion of the spinal interbody market dominated by PEEK products, which in 2005 approximates $221 million."

Mr. Owusu-Akyaw continued, "We have coordinated the design of our GraftCage(TM) Product Line with the design of our Xpanse(TM) Bone Inserts to allow us to have an Xpanse(TM) Bone Insert which can be utilized with each GraftCage(TM) Product configuration. When used together, the GraftCage(TM) Products and the Xpanse(TM) Bone Inserts create a unique vertebral body spacer allowing for maximum endplate contact, structural support, osteoinductivity and osteoconductivity. We believe the use of our Xpanse(TM) Bone Inserts with our GraftCage(TM) PEEK based products gives us a competitive advantage over other spinal implants manufactured from PEEK."

The GraftCage(TM) TLX, like the GraftCage(TM) ACX, is designed for strength and ease of insertion by surgeons, can be implanted utilizing existing Osteotech instrumentation and features titanium markers to facilitate intra-operative and post-operative radiographic assessments. The GraftCage(TM) TLX is intended to replace a collapsed, damaged, or unstable vertebral body in the thoracic or lumbar spine. It is indicated for a partial or total vertebrectomy in cases of tumor or trauma related damage to the vertebral body. The GraftCage(TM) TLX is intended to achieve anterior decompression of the spinal cord and neural tissues and to restore the height of a collapsed vertebral body.
