    • A valve prosthesis for controlling the flow of blood through a cardiac opening in which a stent (b) is adapted to be permanently secured to the cardiac tissue around a cardiac opening (a) and the stent (b) forms a cylindrical opening having a preset inside diameter not less than the diameter of the cardiac opening (a) or is slightly larger than the diameter of the cardiac opening (a). A valve member (c) is releasably connected to stent (b) to control the flow of blood through the cardiac opening (a). The valve member (c) may be releasably connected to the stent (b) by means of a set of teeth (3) that are wedged into an inside circumferential groove (2) extending around the stent ring (b') or a thread set (3) can engage a thread (2) on the stent ring (b').
    • 一种用于控制通过心脏开口的血液流动的瓣膜假体,其中支架(b)适于永久固定在心脏开口(a)周围的心脏组织和支架(b)上,形成具有预设的圆柱形开口 内径不小于心脏开口(a)的直径或略大于心脏开口(a)的直径。 阀构件(c)可释放地连接到支架(b),以控制通过心脏开口(a)的血液流动。 阀构件(c)可以通过一组齿(3)可释放地连接到支架(b),齿组件楔入到围绕支架环(b')延伸的内周向槽(2)中或螺纹组 (3)可以接合支架环(b')上的螺纹(2)。
