A system of heart valves that includes a radially self-expandable cylinder and a valve. The cylindrical body has an inflow end and an outflow end, and the outflow end has a proximal portion and a plurality of beams. The plurality of beams are placed distal to the proximal portion in the outflow direction. In addition, the cylindrical body has struts having peaks and valleys at the inflow end of the cylindrical body, and the proximal portion of the outflow end has the peaks and valleys in the outflow direction. It is installed distally. Further, the cylindrical body is configured such that the inflow end protrudes outward in the radial direction by movement of the proximal portion of the outflow end in the radial direction, and the strut is arranged in the mountain. The trough is configured to project outward in the radial direction by the movement in the radial direction. [Selection] Figure 1心臓弁のシステムで、半径方向に自己拡張可能な筒状体と弁とを含む。前記筒状体は、流入端と流出端を有し、該流出端は、近位部分と複数のビームを有する。該複数のビームは、流出方向に、前記近位部分の遠位に設置される。これに加えて、前記筒状体は、前記筒状体の前記流入端に、山と谷を有するストラットを有し、前記流出端の前記近位部分は、前記流出方向に、前記山と谷の遠位に設置される。さらに、前記筒状体は、前記流出端の前記近位部分の、半径方向の内側の動きによって、前記流入端が半径方向の外側に張り出すように構成され、前記ストラットの配置は、前記山の、半径方向の内側の動きによって、前記谷が半径方向の外側に張り出すように構成される。【選択図】 図１
