PROSTHETIC VALVE, BASE MATERIAL FOR FORMING PROSTHETIC VALVE, AND PRODUCTION PROCEDURE OF PROSTHETIC VALVE

摘要

PROBLEM TO BE SOLVED: To provide a prosthetic valve capable of providing a valve element with a quality similar to that of an outer tube part without elongating a time required for production, a base material for forming the prosthetic valve, and a production procedure of the prosthetic valve.SOLUTION: A connective tissue 12 constitutes an outer tube part 4 and a cylindrical valve element 5. The valve element 5 is provided in the interior of the outer tube part 4. The valve element 5 has a shape formed by folding back one end of the outer tube part 4. A plurality of portions of a distal end of the valve element 5 that are provided at some intervals apart from one another in the circumferential direction are fixed to the inner face of the outer tube part 4. The cylindrical valve element 5 comprises a plurality of valve lobes 6 for opening/closing a flow pass X provided in the inside thereof. The valve lobes 6 are bent inward to come into contact with each other and close the valve element 5.
