Method for manufacturing artificial valve leaflets and artificial valve leaflets and artificial blood vessels with valves

摘要

PROBLEM TO BE SOLVED: To provide an instrument used for reducing hemodynamic stress on a valve leaflet and making it possible to more faithfully reproduce an actual valve behavior. An artificial valve apex instrument 10 has a surface portion corresponding to the shape of an artificial valve apex, and a film is provided along a forming edge of the surface portion in a state where a predetermined membrane body is in contact with the surface portion. A valve leaflet forming mold 11 configured to form an artificial valve leaflet by excising the body, and a valve leaflet mounting guide that functions as a guide for fixing the artificial valve leaflet at a desired position on the inner wall of the blood vessel. It has 12 and. The valve leaflet forming mold 11 has a three-dimensional chevron shape having a curved surface around the top T, and has a joint length corresponding to a portion where the plurality of artificial valve leaflets attached to the inner wall are joined when the valve is closed. The area L is included in the surface portion. The valve leaflet mounting guide 12 includes a base and standing walls that stand up from a plurality of locations on the outer edge side of the base, and a space S having a shape substantially corresponding to the lower region of the artificial valve leaflet is formed between the standing walls. It is formed. [Selection diagram] Fig. 1
