The Trevo devices were first cleared in 2012 to help people who could not be given the clot-busting drug t-PA. The devices, when fully expanded to up to six millimeters in diameter, allow doctors to grip a blood clot inside a vessel and remove it via catheter or sheath, the FDA said in a news release.
The new approval expands the devices' use to include a broader group of patients, the agency said.
Stroke kills some 130,000 people in the United States annually, making it the 5th-leading cause of death, according to the U.S. Centers for Disease Control and Prevention.
Potential risks of the devices include failure to retrieve a clot, device breakage and blood vessel damage.
The devices are manufactured by Concentric Medical, based in Mountain View, Calif.
