CRYOLIFE AND ENDOLOGIX SIGN DEVELOPMENT AGREEMENT FOR BIOFOAM

Endologix to develop CryoLife’s innovative, self-expanding sealant as a filling agent for aortic aneurysms

ATLANTA, Ga. and IRVINE, Calif. (January 10, 2005) – CryoLife, Inc. (NYSE: CRY) and Endologix, Inc. (Nasdaq: ELGX) today announced the signing of a development and marketing agreement for the percutaneous or endovascular delivery of CryoLife’s BioFoam™ as a self-expanding sealant for endovascular aortic aneurysm grafts. Under the agreement, Endologix will be responsible for preclinical, clinical, and regulatory activities and costs, and CryoLife will manufacture BioFoam for clinical use and commercial sale and receive a royalty on potential future product sales.

BioFoam is a protein hydrogel adhesive in preclinical development. The product contains an expansion agent, which has the potential to rapidly fill and seal internal body cavities, such as aneurysm sacs, and provide hemostasis in penetrating wounds and severe trauma. BioFoam is based on the same platform technology as CryoLife’s BioGlue®, which is FDA approved to control bleeding as an adjunct to sutures and staples in the open surgical repair of large vessels. BioGlue is CE marked in the European Community and approved in Canada for use in soft tissue repair.

“BioFoam represents an outstanding business opportunity for Endologix, using a well-described and often-used predicate in open surgical procedures in a market that Endologix currently serves,” said Paul McCormick, Endologix president and chief executive officer. “Endoleaks, or blood flow into an excluded aneurysm sac, are a significant factor for mid- and long-term failure of endovascular aneurysm repair. Our near-term focus will be on developing BioFoam as an effective agent for percutaneous treatment of endoleaks, irrespective of stent graft manufacturer, while longer-term, BioFoam has the potential to make minimally invasive treatment of abdominal aortic aneurysms (AAA) a more durable procedure.”

“BioFoam is an innovative and versatile product that should prove effective in multiple medical applications,” said Steven G. Anderson, CryoLife president and chief executive officer. “Through agreements with companies with specialized skills and market access, such as Endologix, we expect to improve the value of this asset with application-specific development and to receive a royalty on product sales and earn a manufacturing margin. We are delighted to enter into this agreement with Endologix, and look forward to moving BioFoam into clinical development.”

Endologix intends to begin preclinical development of BioFoam during the first quarter of 2005, and to start clinical testing for the treatment of type 2 endoleaks in mid-year 2006.

“With our Powerlink® System, we are addressing the failings of first-generation endoluminal stent grafts (ELG), and with BioFoam, we are addressing the entirety of the ELG procedure to make this approach the standard of care,” added Mr. McCormick. “We are pleased to further establish our position of industry leadership and product innovation.”

CryoLife’s BioGlue Surgical Adhesive is FDA approved as an adjunct to sutures and staples for use in adult patients in open surgical repair of large vessels and is CE marked in the European Community and approved in Canada for use in soft tissue repair and approved in Australia for use in vascular and pulmonary sealing and repair.

About Endologix
Endologix, Inc. develops and manufactures minimally invasive treatments for vascular diseases. Endologix's Powerlink System is an endoluminal stent graft for treating abdominal aortic aneurysms (AAA). AAA is a weakening of the wall of the aorta, the largest artery in the body, resulting in a balloon-like enlargement. Once AAA develops, it continues to enlarge and, if left untreated, becomes increasingly susceptible to rupture. The overall patient mortality rate for ruptured AAA is approximately 75%, making it the thirteenth leading cause of death in the United States. In October 2004, Endologix received approval to market the Powerlink in the U.S. Additional information can be found on Endologix’s web site at www.endologix.com.
