Cardiac valve prosthesis
First Claim
1. A method of repairing a native aortic valve, the method comprising:
- positioning an aortic valve prosthesis at an implantation site proximate the native aortic valve to be repaired, the aortic valve prosthesis including an armature and a plurality of prosthetic valve leaflets, the armature including first and second annular elements, a plurality of anchor members extending between and connecting the first and second annular elements, and a plurality of valve support members extending from at least one of the first and second annular elements, the plurality of prosthetic valve leaflets being coupled to and supported by the valve support members; and
radially expanding the armature such that each of the anchor members arches radially outward from the first annular element to the second annular element and engages a wall of a respective one of a plurality of native Valsalva sinuses located distal to the native aortic valve so as to enable anchorage of the aortic valve prosthesis at the implantation site.

Abstract
A method of repairing a native cardiac valve such as the aortic valve includes positioning a cardiac valve prosthesis at an implantation site proximate the native cardiac valve to be repaired. The cardiac valve prosthesis includes an armature and a plurality of prosthetic valve leaflets, the armature including first and second annular elements, a plurality of anchor members extending between the first and second annular elements, and a plurality of valve support members extending from at least one of the first and second annular elements, the plurality of prosthetic valve leaflets being coupled to and supported by the valve support members. The method further includes radially expanding the cardiac valve prosthesis such that each of the anchor members arches radially outward from the first annular element to the second annular element and engages a wall of a respective one of a plurality of native Valsalva sinuses located distal to the native cardiac valve so as to enable anchorage of the cardiac valve prosthesis at the implantation site.

14. A method of repairing a native aortic valve, the method comprising:
-
positioning an aortic valve prosthesis in a radially contracted configuration at an implantation site proximate the native aortic valve to be repaired, the cardiac valve prosthesis including an armature and a valve sleeve including a plurality of prosthetic valve leaflets, the armature including first and second annular elements, a plurality of anchor members extending between and connecting the first and second annular elements, and a plurality of valve support members extending between and connected to the first and second annular elements, the valve sleeve being coupled to the armature; and allowing the armature to radially expand such that each of the anchor members arches radially outward from the first annular element to the second annular element and engages a wall of a respective one of a plurality of native Valsalva sinuses located distal to the native aortic valve so as to enable anchorage of the aortic valve prosthesis at the implantation site. - View Dependent Claims (15, 16, 17, 18, 19, 20)
