摘要: A mitral valve prosthesis consists of a support housing (stent) with large base ring that bears two stays which substantially extend in the axis direction and are connected by curved walls for securing flexible cusps. The free ends form an inner In order to avoid possible mutual interference between heart functions, (12) has top view closed, non-round shape common longitudinal (15) but transverse half-axis (16, 17) different sizes. (18, 19) lie on transition halves valve. less wall (13) carries (mural) cusp (11) having smaller surface higher angle inclination relative than more (14).
