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, and a plurality of struts including at least one motion buffer member are incorporated therein. The valve is connected to the tubular body and includes a plurality of leaflets. The cloth is disposed on an outer surface of the cylindrical body and an outer surface of the operation buffer member. In addition, when the outflow end of the cylindrical body moves inward in the radial direction by the movement of the valve leaflet, the motion buffer member does not move inward in the radial direction together with the outflow end of the cylindrical body. It is configured as follows. [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し、少なくとも1つの動作緩衝部材を含む複数のストラットが組み込まれる。前記弁は、前記筒状体と連結され、複数の弁尖を含む。前記布は、前記筒状体の外表面と前記動作緩衝部材の外表面に配置される。これに加えて、前記動作緩衝部材は、前記筒状体の前記流出端が前記弁尖の動きにより半径方向の内側に動くとき、前記筒状体の前記流出端とともに半径方向の内側に動かないように構成されている。【選択図】 図1
