Abstract: An endovenous valve transfer stent (10) has an elongated tubular open-work body (12) having a network of longitudinally extending ribs (13) interconnected by laterally extending zigzag struts (14). The struts define a plurality of barbs (15, 17) in opposing longitudinal directions. The body (12) has a first end and a second end, and includes a longitudinal cut through the struts (14) from the first end to the second end. A seam (19) is defined between adjacent cut ends of each strut. The body (12) is adapted, in use, to vary in its diameter to receive a donor valve containing vein segment (20) longitudinally therethrough.
