METHOD FOR MANUFACTURING ARTIFICIAL VALVED CONDUIT AND ARTIFICIAL VALVED CONDUIT THEREBY

摘要

PURPOSE: A method for manufacturing an artificial valve conduit and an artificial valve conduit manufactured thereby are provided to improve the lifetime and function of an artificial valve conduit by forming a valve in a gore-tex artificial blood vessel. CONSTITUTION: A method for manufacturing an artificial valve conduit is as follows. Inner circumference of a conduit section(110) facing the outside is surrounded with a valve part(120). The long side(122) of the valve part is welded to the opening edge of the conduit section. Three valve leaflets(130) are formed by welding the plane(124) of the valve part to three spots of the conduit section in the axial direction of the conduit section. The conduit section is flipped again so that the outer circumference thereof can face the outside.
