Device Approved for Abdominal Aortic Aneurysms

Last Updated: December 21, 2010.

TUESDAY, Dec. 21 (HealthDay News) -- Medtronic's Endurant AAA Stent Graft system, designed to treat abdominal aortic aneurysms, has been approved by the U.S. Food and Drug Administration, the company said Tuesday.

Some 1.2 million people have an abdominal aortic aneurysm, which typically causes no symptoms, Medtronic said in a news release. About 70 percent to 90 percent of such patients die if the aneurysm ruptures, the company added.

The newly approved device is a flexible wire frame sewn into a fabric tube. It's implanted in the weakened portion of the aorta, reducing pressure on the aneurysm and diminishing the risk of rupture.

The device is delivered via catheters that are inserted in blood vessels in the groin, Medtronic said.
