Abstract
A valve delivery device and method of use is provided. In one embodiment, a method for attaching a valve prosthesis to a target tissue includes providing a ring having a portion defining a groove and a plurality of fasteners coupled to the ring. A portion of the valve prosthesis is placed in the groove on the ring. The valve prosthesis portion in the groove is then secured to the ring. The ring is mounted on a delivery device and the delivery device is positioned so that the fasteners will engage the target tissue when the fasteners are deployed. A shaped plunger member may then deployed through an interior of the ring to swing said fasteners from a first position to a second tissue engagement position.
