Abstract
A heart valve and tissue repair device for independently, selectively and sequentially grasping heart valve leaflets and independently, selectively and sequentially applying one or more fasteners thereto is disclosed. The device includes a leaflet engaging tip having one or more graspers capable of individually and sequentially grasping leaflets, and one or more deployable fasteners capable of fastening the leaflets. An actuation system for the device individually and selectively controls the graspers and deploys the one or more fasteners. Vacuum pressure from an external vacuum source can be used to grasp the leaflets via a selector system that controls the actuation system so as to individually and sequentially apply vacuum force to the graspers.
