| titleOfInvention | Two leaflet prosthetic heart valve |
| abstract | A double-wing heart valve prosthesis has an essentially circular valve ring (20), the inner circumference (21) of which delimits a flow channel (24) for blood flow, and two essentially half-moon-shaped valve wings (50, 70), both of which can be pivoted independently of one another common axis (90) are articulated. Depending on the direction of blood flow, these two flap wings (50, 70) can assume an open position substantially vertical to the flap ring plane (44) or a closed position essentially in the direction of the flap ring plane (44), in which both flap wings (50, 70) close the flow channel (24) almost completely with their combined surfaces. In order to offer the surgeon an additional possibility for influencing the flow conditions, it is provided that the axis (90) is arranged eccentrically, that is to say parallel and at a distance from a circle diameter on the valve ring (20), and the one valve wing (70) has a larger one Has surface than the other flap wing (50). Preferably, the larger-area flap wing (70) can close about 55 to 80% of the flow channel cross-section (25), and the smaller-area flap wing (50) can close about 45 to 20% of the flow channel cross-section (25). |
