Abstract
According to one aspect, heart valve leaflet removal apparatus of the present invention comprises a pair of cooperating cutting elements, a holder and members for manipulating the cutting elements. The cooperating cutting elements are adapted for cutting and removing leaflets from an aortic valve in a patient'"'"'s heart, one of the cutting elements is rotatably coupled the other of the pair of cutting elements. The holder is coupled to one of the cutting elements and is adapted to receive the cut leaflets and the cutting elements and holder are configured for delivery to the valve leaflets through an aortotomy formed in a patient'"'"'s aorta. In one variation, the pair of cooperating cutting elements and holder have a radial dimension and are radially collapsible. Replacement valve delivery apparatus also is provided.

14. A replacement valve delivery system comprising:
-
heart valve prosthesis delivery apparatus for placing an aortic stentless valve prosthesis in a patient'"'"'s heart comprising an aortic stentless valve prosthesis support having a proximal portion and a distal portion and a plurality of fasteners ejectably mounted therein, said distal portion being adapted to be releasably coupled the aortic valve prosthesis, and said valve prosthesis support being configured for delivery to the heart through an aortotomy formed in the patient'"'"'s aorta; and
a balloon adapted to be placed in the valve prosthesis and urge at least a portion of the valve prosthesis against the inner wall of the aorta of the patient so that when adhesive is applied to an exterior portion of the valve prosthesis and the valve prosthesis urged against the inner wall of the aorta said exterior portion can adhere to the inner wall of the aorta - View Dependent Claims (15)

16. A method of repairing an aortic valve comprising:
-
removing aortic leaflets from a patient'"'"'s aortic valve;
providing aortic valve prosthesis on delivery apparatus where the valve prosthesis has an annular portion;
introducing the valve prosthesis through an aortotomy formed in the patient'"'"'s aorta with the delivery apparatus; and
simultaneously ejecting a plurality of self-closing clips from the delivery apparatus through said annular portion and then into the patient'"'"'s aortic root to secure the valve prosthesis to the aortic root of the patient. - View Dependent Claims (17, 18, 19, 20)
