Apparatus and method for heart valve repair
First Claim
1. A device for repair of a heart valve leaflet, the device comprising:
- an elongated body having a proximal end and a distal end;
a jaw mechanism on the distal end of the elongated body, the jaw mechanism including a first jaw and a second jaw operable to pivot relative to one another between an open position and a closed position, the jaw mechanism in the open position defining a receiving space between the first jaw and the second jaw, the second jaw including a slot forming a forked edge at a distal end of the second jaw and at least one sharpened structure projecting laterally from the second jaw configure to provide traction for the jaw mechanism when the jaw mechanism is rotated against the tissue of the heart valve leaflet; and
a rivet mounted to the first jaw and movable from a stored position to an application position, the rivet in the application position projecting away from the first jaw toward the second jaw, the rivet having a sharp free end adapted to pierce the heart valve leaflet,wherein movement of the jaw mechanism from the open position to the closed position with the heart valve leaflet in the receiving space and the rivet in the application position causes the rivet to pierce the heart valve leaflet, the slot being sized to receive the sharp free end of the rivet between the forked edge when the rivet is in the application position and the second jaw is in the closed position.

Abstract
A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.
