A system of heart valves that includes a radially self-expandable tubular body, a valve, and a tubular fabric. The cylindrical body has an inflow end and an outflow end. The valve is connected to the tubular body and includes a plurality of leaflets. The valve leaflets are supported by only two of the plurality of beams, and a connecting portion connects the inflow end of the cylindrical body and the plurality of beams. The number of connecting parts is equal to the number of leaflets. In addition, each of the plurality of beams is directly connected to an adjacent beam so that the plurality of beams reach the entire length of the outer periphery of the cylindrical body at the outflow end. [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、筒状布とを含む。前記筒状体は、流入端と流出端を有する。前記弁は、前記筒状体と連結され、複数の弁尖を含む。該弁尖は、前記複数のビームのうち、２つのビームのみによって支えられ、連結部が前記筒状体の前記流入端と前記複数のビームとを連結する。連結部の数は、前記弁尖の数と等しい。これに加えて、前記複数のビームの各ビームは、前記複数のビームが前記流出端において、前記筒状体の外周の全長に及ぶように、隣接するビームと直接連結される。【選択図】 図１
