IRVINE, Calif., Oct. 13 /PRNewswire-FirstCall/ -- Endologix, Inc. (Nasdaq: ELGX - News), developer of minimally invasive treatments for aortic disorders, announced today that it has conducted further evaluation of the patent infringement lawsuit filed against the company last week by Cook Medical, and of the patents asserted in the lawsuit. Based upon this evaluation, Endologix believes that the alleged infringement is without merit and the company intends to vigorously defend its position.

John McDermott, Endologix President and Chief Executive Officer, said, "We are pleased that our initial evaluation of these claims, which Cook Medical waited for years to assert, has already yielded support for numerous promising defenses."

About Endologix, Inc.

Endologix, Inc. develops and manufactures minimally invasive treatments for aortic disorders. The Company's flagship product is the Powerlink® System, which is an endovascular stent graft for the treatment of 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. Additional information can be found on Endologix's Web site at www.endologix.com
