  • Artificial vascular valves
    Patent number: 6126686
    Abstract: A method for preparing vascular valves from submucosal tissue is described. Both bicuspid and tricuspid valve constructs are described. The bicuspid constructs can be formed with or without a supporting stent. The tricuspid constructs are formed by fixing submucosal tissue to a supporting stent, folding the submucosal tissue, and forming the valve commissures from the folded submucosal tissue by cutting along the folds. The artificial vascular valves are useful for replacing damaged or diseased valves of a warm-blooded vertebrate.
