American Medical Systems Widens Its Lead in Women's Pelvic Health; Launch of InteXen LP™ Biologic Graft Adds Superior Characteristics to Market-Leading Surgical Solutions

Business Wire, Nov 16, 2005

MINNEAPOLIS -- American Medical Systems Holdings, Inc. (NASDAQ:AMMD) announced today its early feedback from physicians on the clinical use of the recently introduced InteXen LP(TM) product. InteXen LP is a lyophilized porcine dermal matrix graft material for use in pelvic floor reconstructive surgery for stress urinary incontinence and pelvic organ prolapse in women. This latest addition to the AMS product portfolio builds upon AMS' long held strategy of providing a breadth of alternatives to surgeons for their choice in meeting patient needs.

"In my early clinical experience with InteXen LP, I am very encouraged by the healing response in my patients," stated James Chivian Lukban DO, Director of the Division of Urogynecology and Associate Professor of Obstetrics and Gynecology at Eastern Virginia Medical School. "I am extremely impressed with the post-operative results in this regard."

Dr. Lukban added, "Up to now, there has been a general lack of clinical data supporting the use of biologics in graft augmented repairs. The early data does show that the InteXen LP biologic does generate an improved healing response. In addition, AMS is pioneering a prospective clinical trial that will study the long term outcomes of the use of biologics in pelvic floor reconstruction."

Martin J. Emerson, President and Chief Executive Officer, commented, "InteXen LP represents the ninth new product AMS has launched into the women's pelvic health market in the last ten months and it further strengthens our leadership position. I am certainly very pleased with the early results physicians have experienced with InteXen LP, and look forward to the results of our recently announced prospective trial."

Dr. Kurt McCammon, Assistant Professor of Urology at Eastern Virginia Medical School, specializing in pelvic floor reconstruction, noted, "As one of the initial users of InteXen LP, I am impressed with its softness and improved handling characteristics. This makes it not only easier to implant, but more conforming to my patients' natural anatomies. Its handling characteristics are greatly improved by the fact it is pre-attached to products such as BioArc, Apogee and Perigee, saving me significant time in the operating room."

Mr. Emerson reiterated, "AMS remains committed to working closely with physicians to develop innovative new products for the surgical treatment of prolapse and incontinence as well as to partner with hospitals to continuously improve patient outcomes."
