Endologix Honors Innovators of Aortic Therapy at VEITHsymposium

Endologix, Inc. ELGX, a developer and marketer of innovative treatments for aortic disorders, today honored four innovators of aortic therapy at the 45^th Annual Symposium on Vascular and Endovascular Issues, Techniques, Horizons (VEITHsymposium®), a meeting of endovascular specialists highlighting developments in the treatment of vascular disease.

At an event called "Learning from the Past to Shape the Future: Evolution of Aortic Therapy," Endologix recognized the surgeons who advanced aortic repair therapy and initiated early randomized controlled trials of endovascular aneurysm repair (EVAR). Prior to the early 1990s, patients who were not eligible for open surgical repair were left untreated until early innovators challenged the status quo and developed endovascular grafts.

"Randomized controlled trials are the gold standard for evaluating any therapy, and several of our honorees led studies that helped set the standard for the entire EVAR category," said Matt Thompson, MD, Chief Medical Officer of Endologix. "These innovators revolutionized the treatment of abdominal aortic aneurysms, and we are proud to recognize the work they are doing to advance the field of vascular surgery. To advance the standard of care, we believe future products must be evaluated for superior outcomes as compared to conventional EVAR grafts."

The distinguished honorees were:

• Jean-Pierre Becquemin, MD, study chair of the ACE trial;
• Jan Blankensteijn, MD, principal investigator of the DREAM trial;
• Roger Greenhalgh, MD, leader of the EVAR-1 trial;
• Frank Veith, MD, leader of the team that performed the first EVAR procedure in the United States in 1992, setting the course for clinical studies and therapeutic advances that would define the EVAR category.

Other physicians acknowledged for their substantial contributions included Ted Diethrich, MD, Roy Greenberg, MD, Frank Lederle, MD, Michael Marin, MD, Juan Parodi, MD, and Nikolai Volodos, MD.

About Endologix, Inc.

Endologix, Inc. develops and manufactures minimally invasive treatments for aortic disorders. The Company's focus is in endovascular stent grafts 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 an 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 80%, making it a leading cause of death in the U.S. For more information, visit www.endologix.com.
