FDA Approves Device to Maintain Blood Flow During Artery Bypass Brain Surgery
Date:3/10/2011

SILVER SPRING, Md., March 10, 2011 /PRNewswire-USNewswire/ -- The U.S. Food and Drug Administration today approved a surgical kit that allows neurosurgeons to reroute blood flow around an aneurysm or a tumor in the brains of patients at greater risk of stroke during standard bypass surgery.

The ELANA (Excimer Laser Assisted Non-Occlusive Anastamosis) Surgical Kit allows neurosurgeons to create a bypass without shutting off the blood flow. It consists of a small platinum ring and a hand piece connected to a surgical laser and suction tubing.

Standard bypass surgery in the brain requires clipping the artery to halt blood flow during the procedure. The surgery is not considered safe for about 1,000 patients annually in the United States because temporarily shutting off their blood flow would put them at high risk of stroke. The group  includes patients ages 13 and older who have an enlarged, weak area in a brain artery (cerebral aneurysm), tumors at the base of the skull that could impact blood flow in brain arteries, or other issues that could complicate conventional surgery.

"The ELANA Surgical Kit may help those with a rare condition for whom there previously was no treatment option," said Jeffrey Shuren, M.D., director of the FDA's Center for Devices and Radiological Health.

To create the bypass, a surgeon sutures the ring and a section of replacement blood vessel onto the surface of the affected artery. Once attached, the surgeon tunnels the tip of the laser handpiece down the open end of the replacement blood vessel until the tip of the laser touches the ring.

The laser then cuts a circular hole in the affected artery, and suction removes the cut tissue. The process is repeated with a second replacement blood vessel. Once both replacement blood vessels are in place, the open ends of the t
