<P>PROBLEM TO BE SOLVED: To provide venous valve replacement and, in particular, replacement venous valves to lower extremities and a therapeutic method of treating venous circulartory disorders, although the venous system and venous disease were not considered an arena for stent application. <P>SOLUTION: A stent portion 51 and a valve device 43 comprises a functionally unitary mesh-type construction. The stent portion 51 accommodates the inner lumen of venous portion 10 sufficient to allow valve portion 55 sufficient diameter to properly function as an artificial venous valve. The stent is manufactured from a suitable biocompatible material, and preferably, is percutaneously disposed in the vascular system. <P>COPYRIGHT: (C)2010,JPO&INPIT |
