Including a conduit extending from the outlet end to the inlet end along a central axis and having a central axis, a valve body, extends to the conductor tube from the body, a curved portion connecting the body defining each, will be disclosed, including flexible valve three leaves and (130), polymer heart valve (100) at least. Each, each pair of leaflets defines a commissure portion located proximal to the body. Full open position biased towards leaving the antegrade blood flow during along part open position at rest, in the direction of the outlet end from the inlet end, from the central axis, and leaflets of 3 pieces, the inflow end from the outlet end at least defining the closed position biased towards towards retrograde blood flow during along the direction to the center axis.中心軸を有し、かつ該中心軸に沿って流入端から流出端まで延在する導管を含む、弁本体と、該本体から該導管内へと延在し、該本体との連結湾曲部を各々規定する、少なくとも3枚の屈曲性弁葉(130)とを含む、ポリマー心臓弁(100)を開示する。弁葉のそれぞれの対は、各々、該本体の近位に位置する交連部を規定する。少なくとも3枚の弁葉は、静止時の部分開口位置、流入端から流出端への方向に沿う順行血流時の、中心軸から離れる方に偏った完全開口位置、および流出端から流入端への方向に沿う逆行血流時の、中心軸に向かう方に偏った閉口位置を規定する。
