Abstract
An implantable prosthetic device includes a coaption portion, paddles, and clasps. The paddles are moveable from a closed position to an open position. The clasps are also moveable from an open position to a closed position. The clasps include a fixed arm and a plurality of movable arms. The implantable prosthetic device can be used to repair a native valve, such as a native mitral valve.
