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.COPYRIGHT: (C)2015,JPO&INPIT【課題】弁体についても、生産に要する時間を長くすることなく、外管部と同程度の品質を得ることのできる人工弁、人工弁形成用基材、及び人工弁の生産方法の提供。【解決手段】結合組織12で外管部4と筒状の弁体5とを構成する。弁体5を外管部4の内側に設ける。弁体5を外管部4の一端を内側に折り返した形状とする。弁体5の先端部のうちの周方向に間隔をあけた複数箇所を外管部4の内面に止着する。筒状の弁体5がその内側の流路Xを開閉する複数の弁葉6を構成する。弁葉6が内側に撓むことにより、互いに接触して弁体5を閉じる。【選択図】 図1
