Integra LifeSciences Announces CE Mark for DuraGen Plus(TM) Adhesion Barrier Matrix

PLAINSBORO, N.J., Oct. 18, 2004 (PRIMEZONE) -- Integra LifeSciences Holdings Corporation (Nasdaq:IART) today announced that it has received CE Mark Certification for the DuraGen Plus(TM) Adhesion Barrier Matrix. The product is approved as a barrier against adhesions following spinal and cranial surgery and for restoration of the dura mater. Integra is introducing the DuraGen Plus(TM) Adhesion Barrier Matrix to international physicians at the 54th Annual Meeting of the Congress of Neurological Surgeons in San Francisco this week. Integra will launch the product outside the United States during the fourth quarter through its direct sales force and international distributor network.

Spinal adhesions are a frequent consequence of spine surgery and are associated with post-operative pain and disability. A significant portion of laminectomy and discectomy patients require re-operation for severe pain. DuraGen Plus Adhesion Barrier Matrix provides a treatment option for prophylactic adhesion prevention. Integra estimates that the total available worldwide market for treatment of spinal adhesions is in excess of $300 million, and the worldwide market for duraplasty is approximately $110 million. Both markets are addressed by DuraGen Plus Adhesion Barrier Matrix.

"Our application for CE Mark certification for these expanded indications was supported by clinical studies demonstrating that application of DuraGen Plus matrix provides an effective method for preventing dural adhesions following spinal and cranial surgical procedures," said Simon Archibald, Ph.D., Vice President of Clinical Affairs. "Since it was launched in the U.S., DuraGen Plus has proven to be a highly effective dural grafting system. This recent CE Mark approval, as an adhesion barrier matrix, is another significant milestone for this family of products."

The outcomes of a clinical study of the application of the DuraGen matrix to prevent spinal adhesions will be summarized at the CNS meeting in a poster entitled, "Dural graft matrix as an adhesion barrier," presented by Doctors Inaki Arrotegui and J. Luis Llombart of Valencia, Spain. The investigators concluded that application of the DuraGen matrix resulted in reduced post-operative patient pain, lower incidence of adhesions as assessed by MRI, and an overall decrease in the incidence of pain-related re-operation.

Integra previously launched the DuraGen Plus Dural Graft Matrix, its next-generation onlay dural graft, to the U.S. market in October, at the 2003 CNS meeting. The DuraGen Plus Adhesion Barrier Matrix, with expanded adhesion barrier indications, is not available or cleared for sale within the United States.
