Abstract
An intra-annular mounting frame for an aortic valve having native aortic cusps is provided which includes a frame body with native leaflet reorienting curvatures and interconnecting points; the curvatures shaped to be received inside the valve below the native aortic cusps and to reorient the native aortic cusps within the aortic valve, where each of the curvatures extends concavely upward from a reference latitudinal plane tangential to each curvature's base.
Claims23
A method of repairing a bicuspid aortic valve having an aortic wall, native aortic cusps, and commissures, the method comprising:
- a) providing an intra-annular mounting frame comprising:
- two curvatures having ends,
- two points interconnecting the ends of the curvatures, and
- two posts such that a post extends from each point;
- wherein the curvatures are shaped to be received inside the valve below the native cusps and to reorient the cusps within the valve, and
- wherein the posts extend from the points at an angle of 0 to about 30 degrees when measured from an internal area of a vertical plane;
- b) inserting the intra-annular mounting frame into an aortic valve annulus with the curvatures positioned adjacent to where the native aortic cusps connect to the aortic wall;
- and
- c) suturing the intra-annular mounting frame to the aortic valve annulus with the sutures passing through the aortic wall and passing both above and below the native aortic cusps to implant the intra-annular mounting frame into the aortic valve.

- and
- c) suturing the intra-annular mounting frame into the aortic valve annulus with the sutures engaging the intra-annular mounting frame from below the aortic valve and passing through the aortic wall and under the native aortic cusps to above the cusps to implant the intra-annular mounting frame into the aortic valve to reduce the diameter of the aortic valve.
