Biological replacement valve assembly

摘要

A prosthesis device for percutaneous implantation that includes an expandable stent and a biological venous valvular replacement for a defective valve mounted inside the expanded stent. The wall thickness of the vein is reduced to a diameter that is about equal to the inside diameter of the expanded stent and is sutured to the inside of the expanded stent so that the vein is supported in a fully opened circular configuration.
