The U.S. Food and Drug Administration 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. The Amplatzer PFO Occluder device is manufactured by St. Jude Medical Inc. based in Plymouth, Minnesota.
