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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An intra-annular mounting frame for a bicuspid aortic valve, comprising:
 two curvatures having ends,   two points interconnecting the ends of the curvatures, and   two posts extending from each of the points;   wherein the curvatures are shaped to be received inside the valve below native cusps of the valve and to reorient the cusps within the valve   
     
     
         2 . The intra-annular mounting frame of  claim 1 , wherein the posts extend from points at an angle of about 0 degrees to about 30 degrees wherein measured from an internal area of a vertical plane of the frame. 
     
     
         3 . The intra-annular mounting frame of  claim 1 , wherein the posts extend from points at an angle of about 1 degree to about 30 degrees wherein measured from an internal area of a vertical plane of the frame. 
     
     
         4 . The intra-annular mounting frame of  claim 1 , wherein the posts extend substantially vertically from the points when measured from an internal area of a latitudinal plane of the frame. 
     
     
         5 . The intra-annular mounting frame of  claim 1 , wherein the length of the post is from about 8 millimeters to about 16 millimeters. 
     
     
         6 . The intra-annular mounting frame of  claim 1 , wherein each post has a length of about 70% to about 130% of the radius of the valve. 
     
     
         7 . The intra-annular mounting frame of  claim 1 , wherein the frame has a diameter that is less than the diameter of the valve. 
     
     
         8 . The intra-annular mounting frame of  claim 1 , wherein the frame has a diameter of about 2 millimeters to about 8 millimeters less than the diameter of the valve. 
     
     
         9 . The intra-annular mounting frame of  claim 1 , wherein the diameter of the frame ranges from about 15 millimeters to about 30 millimeters. 
     
     
         10 . The intra-annular mounting frame of  claim 1 , wherein the length of one of the curvatures is up to about 30% larger the other curvature. 
     
     
         11 . The intra-annular mounting frame of  claim 1 , wherein the length of one of the curvatures is up to about 20% larger the other curvature. 
     
     
         12 . The intra-annular mounting frame of  claim 1 , wherein the length of the curvatures is substantially equal. 
     
     
         13 . The intra-annular mounting frame of  claim 1 , wherein the posts are positioned about 90° to about 180° apart on the circumference of the frame. 
     
     
         14 . The intra-annular mounting frame of  claim 1 , wherein the frame has an elliptical shape having a major axis and a minor axis. 
     
     
         15 . The intra-annular mounting frame of  claim 1 , wherein the ratio of the major axis to the minor axis ranges from about 1 to about 1.8. 
     
     
         16 . The intra-annular mounting frame of  claim 1 , wherein the ratio of the major axis to the minor axis ranges from about 1.1 to about 1.8. 
     
     
         17 . The intra-annular mounting frame of  claim 1 , wherein the ratio of the major axis to the minor axis ranges from about 1.2 to about 1.7. 
     
     
         18 . The intra-annular mounting frame of  claim 1 , wherein the ratio of the major axis to the minor axis ranges is about 1.5. 
     
     
         19 . The intra-annular mounting frame of  claim 1 , wherein the frame has a non-axisymmetric shape. 
     
     
         20 . The intra-annular mounting frame of  claim 1 , wherein the frame comprises metal. 
     
     
         21 . The intra-annular mounting frame of  claim 1 , wherein the frame comprises a material selected from the group consisting of plastics, polymers, metal, thermoplastics, resins, and combinations thereof. 
     
     
         22 . The intra-annular mounting frame of  claim 1 , further comprising a surface covering of a polymer fiber cloth. 
     
     
         23 . The intra-annular mounting frame of  claim 1 , wherein the polymer fiber cloth comprises polyethylene terephthalate.
