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