Prosthetic heart valve and method
First Claim
1. A system for replacing a deficient native aortic valve, comprising:
- an implantable prosthetic valve comprising a self-expandable frame and a valve assembly formed with three valve leaflets, the self-expandable frame including a plurality of support beams, each support beam having a plurality of preformed bores for allowing the valve assembly to be anchored to the frame at least in part by stitching that extends through the leaflets and through the preformed bores of the support beams, wherein each leaflet comprises opposing end portions, each end portion being paired with an adjacent end portion of an adjacent leaflet to form commissures, wherein each support beam comprises a pair of parallel, circumferentially spaced support bars and each commissure extends between the support bars of an adjacent pair of support bars; and
a restriction tube adapted for insertion into a patient'"'"'s body;
wherein the prosthetic valve is capable of being crimped for insertion into the restriction tube and wherein the prosthetic valve is capable of self-expansion upon release from the restriction tube for deployment in the deficient native aortic valve.

Abstract
A system for replacing a deficient native aortic valve includes an implantable prosthetic valve having a self-expandable frame and a valve assembly formed with three valve leaflets. The self-expandable frame includes a plurality of support beams, each support beam having a plurality of preformed bores for allowing the valve assembly to be anchored to the frame at least in part by stitching that extends through the leaflets and through the preformed bores of the support beams. The system also includes a restriction tube adapted for insertion into a patient'"'"'s body. The prosthetic valve is capable of being crimped for insertion into the restriction tube and capable of self-expansion upon release from the restriction tube for deployment in the deficient native aortic valve.

22. A system for replacing a deficient native aortic valve, comprising:
-
an implantable prosthetic valve comprising a self-expandable frame and a valve assembly formed with three valve leaflets, the self-expandable frame including a plurality of support beams positioned along an outlet end portion of the valve assembly, each support beam having a plurality of preformed bores for allowing the valve assembly to be anchored to the frame at least in part by stitching that extends through the leaflets and through the preformed bores of the support beams, wherein the leaflets are connected to the support beams only along the outflow end portion of the valve assembly, wherein each leaflet comprises opposing end portions, each end portion being paired with an adjacent end portion of an adjacent leaflet to form commissures, wherein each support beam comprises a pair of parallel, circumferentially spaced support bars and each commissure extends between the support bars of an adjacent pair of support bars, and wherein the valve assembly further comprising an inner tubular portion secured to an interior surface of the frame with annular stitching extending along an inlet end of the tubular portion and annular stitching extending along an outlet end of the tubular portion; and a restriction tube adapted for insertion into a patient'"'"'s body; wherein the prosthetic valve is capable of being crimped for insertion into the restriction tube and wherein the prosthetic valve is capable of self-expansion upon release from the restriction tube for deployment in the deficient native aortic valve. - View Dependent Claims (23, 24)
