<p>A prosthetic valve (20) and an associated method of implanting the valve within a blood vein utilize a valve support ring (22) and a pair of leaflet members (24) hingedly connected to the ring which are positionable within a radial plane of the blood vessel for permitting substantially unidirectional flow through the blood vein. The support ring is not required to be sutured within a blood vein and instead includes an outer surface (28) defining a radially outwardly-directed annular groove (36) so that the valve can be secured within the blood vein by means of a cord (72) tied around of the blood vein and in a tightened condition within the annular groove so that the support ring is held in position along the length of the blood vein as the blood vein is held between the support ring outer surface and the cord.</p> |
