Abstract

An apparatus for the repair of a cardiovascular valve has leaflets comprising a grasper capable of grabbing and co-apting the leaflets of the valve. In a preferred embodiment the grasper has jaws that grasp and immobilize the leaflets, and then a fastener is inserted to co-apt the leaflets. The apparatus is particularly useful for repairing mitral valves to cure mitral regurgitation.
