First Claim
Patent Images
1. An intra-annular mounting frame for a valve having a radius, diameter and circumference, comprising:
- a plurality of curvatures, each of the curvatures curved in a first plane and curved in a second plane with the center of each of the curvatures below the ends of each of the curvatures, with each curvature corresponding to a valve'"'"'s three-dimensional geometry about a cusp of the valve; and
a plurality of points interconnecting the ends of each of the curvatures to form an interior area with each point corresponding to a valve'"'"'s three-dimensional geometry about a commissure of the valve.

25. A method of repairing an aortic valve having an aortic wall, cusps and commissures, comprising:
-
a) providing an intra-annular mounting frame comprising, a plurality of curvatures, each of the curvatures curved in a first plane and curved in a second plane with the center of each of the curvatures below the ends of each of the curvatures, with each curvature corresponding to a valve'"'"'s three-dimensional geometry about a cusp of the valve; and a plurality of points interconnecting the ends of each of the curvatures to form an interior area with each point corresponding to a valve'"'"'s three-dimensional geometry about a commissure of the valve; b) inserting the intra-annular mounting frame directly into the aortic valve annulus with the intra-annular mounting frame positioned up under the cusps; and c) suturing the intra-annular mounting frame into the aortic valve with the sutures passing through the aortic wall and passing both above and below the cusps. - View Dependent Claims (26, 27, 28, 29, 30, 31)

32. A method of repairing an aortic valve having an aortic wall, cusps and commissures, comprising the steps of:
-
a) providing an intra-annular mounting frame comprising, a plurality of curvatures, each of the curvatures curved in a first plane and curved in a second plane with the center of each of the curvatures below the ends of each of the curvatures, with each curvature corresponding to a valve'"'"'s three-dimensional geometry about a cusp of the valve; and a plurality of points interconnecting the ends of each of the curvatures to form an interior area with each point corresponding to a valve'"'"'s three-dimensional geometry about a commissure of the valve; b) inserting the intra-annular mounting frame directly into the aortic valve annulus with the intra-annular mounting frame positioned up under the cusps; and c) employing a plurality of support arcs similar in shape to the curvatures of the intra-annular mounting frame above the cusps of the aortic valve; and d) passing sutures through the aortic wall and between the intra-annular mounting frame and the plurality of support arcs. - View Dependent Claims (33, 34)
