ABSTRACT OF THE DISCLOSURE A cuff for restoring competence to an in- competent venous valve comprises a band of biocom- patible implantable material that is not stretchable at blood flow pressures, the band being of sufficient length to encompass the vein at the site of the venous valve, with portions of the band overlapping, the overlapping portions being joinable together to form a cuff of desired circumference small enough to restore competence yet not too tight to decrease blood flow; in particular the band of the cuff may be notched to accommodate application at a venous juncture or may include loop means adjacent an end portion of the band to which the overlapping end portion of the band is joined.
