    • The invention concerns a prosthesis for replacing heart valves comprising a valve ring (10) with a radius (R) in which at least two essentially flat pivoted flaps (12, 14, 16) are rotatably mounted on an axis (18) in the ring plane such that the axes (18), when projecting on the ring plane, are at a distance of 0.5 R to 0.9 R from the centre of the ring plane, and the edges of the inner sections lie flush with the edges of the corresponding sections of the other pivoted flaps (12, 14, 16) and the pivoted flaps (12, 14, 16), when open, in the area (20) facing the direction of flow are provided with a bevel (24) which runs in the direction of flow from the outside inwards, forming an acute breakaway edge (22).
    • 假体置换心脏瓣膜的,与阀环(10)的半径R为其中至少两个基本上拉伸形成翼片(12,14,16)可旋转地由一个躺在环件轴线的平面(18)支撑,其特征在于 轴(18)在投影到环的平面以0.5的R从该环的平面的中心的距离,以0.9 R和与其它翼片的对应部分的(边缘12齐平的向内面对的部分的边缘, 提供14抵接和16),所述襟翼(12,14,16)在其端部指向在打开状态中的流动面积(20的方向),其具有来自外部的流动方向向内延伸,尖撕开边缘(22)形成倒角(24) ,
