Latest Patents

Sishi Liu holds a patent for a valved vascular prosthesis and its manufacturing method. The invention provides a valved vascular prosthesis that includes an artificial blood vessel and a valve designed for obstruction. The valve is constructed in a skirt state that extends toward the centerline of the artificial blood vessel. It is made by sewing a tubular vascular material onto the artificial blood vessel. One end of the vascular material is connected to the artificial blood vessel radially, while the other end remains free. The entire tubular body of the vascular material is secured to the artificial blood vessel using multiple sutures, which are arranged radially parallel and spaced evenly around the circumference. This prosthesis utilizes a polymer material for sutures, ensuring good biocompatibility when implanted into the human body. The process of manufacturing this prosthesis is simple and easy to mold.
