(medicine/cardiology) a catheter-delivered device that blocks a hole in the wall of a heart. Often the occluder is designed with an umbrella-type design and is folded up until the catheter arrives at the area of the defect in the heart. Once in place the occluder is unfolded on both sides of the defect so that pressure from both sides keeps it in place.
