<p>A vein valve, preferably for the common femoral vein, is described. The valve may be of a monocusp or bicuspid construction. The valve is constructed from the patient's own vein wall tissue, in which case it is necessary to repair the opening made in the vein wall with a precisely shaped, minimally thrombogenic vein wall patch, which may be, and is preferably, synthetic. The synthetic patch may be both heparin and antibiotic bonded and thus confer special advantages.</p> |
