PROBLEM TO BE SOLVED: To provide a prosthetic valve that can be transplanted to a site having short flowing-directional length such as a part between cardiac chambers, a base material for forming the prosthetic valve, and a production procedure of the prosthetic valve.SOLUTION: The prosthetic valve includes a cylindrical valve element 5 consisting of a connective tissue. A base end of the valve element 5 is defined as a fixing part 6. A string-like chorda tendinea 7 is extended from the tip end of the valve element 5. The fixing part 6 of the valve element 5 is fixed to a transplantation side. The tip end of the valve element 5 is fastened by the chorda tendinea 7. A fluid flowing to the tip end side pushingly expands the valve element 5 from the inside to open the valve element. The fluid flowing to the base end side smashes the valve element 5 from the outside to close the valve element.COPYRIGHT: (C)2015,JPO&INPIT【課題】心臓の室間など、流れ方向長さの短い部位に移植す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】結合組織からなる筒状の弁体5を備える。弁体5の基端部を止着部6とする。弁体5の先端部から紐状の腱索7を延設する。弁体5の止着部6を移植部位に止着する。弁体5の先端部を腱索7で留める。先端側に流れようとする流体が弁体5を内側から押し広げて開弁する。基端側に流れようとする流体が弁体5を外側から押し潰して閉弁する。【選択図】 図1
