The U.S. Food and Drug Administration today approved the Amplatzer PFO Occluder device. The PFO Occluder reduces the risk of a stroke in patients who previously had a stroke believed to be caused by a blood clot that passed through a small hole in the heart, called a patent foramen ovale (PFO), and then traveled to the brain.
