Dynamic annulus heart valve employing preserved porcine valve leaflets
First Claim
1. A prosthetic heart valve, comprising:
- a flexible frame means comprising a plurality of arcuate frame struts joined together at a common point and extending radially from said common point to free ends spaced from one another; and
a plurality of preserved natural heart valve leaflets, each having a first free edge, mounted to said frame means such that said free edges of said leaflets extend between the said free ends of said frame struts wherein said leaflets are each provided with a second edge, having an associated strip of aortic tissue and wherein said strips of aortic tissue are joined to one another to enclose said frame struts.

Abstract
A prosthetic heart valve having a frame comprising a plurality of struts joined together at a common point and extending radially from the common point to free ends spaced from one another and a plurality of preserved tissue valve leaflets, each having a free edge, mounted to said frame means such that said free edges of said leaflets extend between the free ends of said frame struts. Each of the leaflets are provided with an associated strip of aortic tissue and the strips of aortic tissue are joined to one another to enclose the frame struts so that no synthetic materials are exposed to the bloodstream with the exception of suture material used to join the adjacent strips of aortic tissue.
