ROTATING CURVE OF ARTIFICIAL HEART VALVE (OPTIONS) AND ARTIFICIAL HEART VALVE (OPTIONS)

摘要

The present invention relates to an improved tricuspid artificial heart valve (100) and an improved sash (110) for use in such a valve. The valve (100) and the flap (110) of the present invention provide improved flow parameters, minimize blood coagulation behind the valves and provide more natural opening and closing intervals. The valve includes a valve body (105), which contains a swivel hinge mechanism (130, 200 and 300), which provides rotation and retention of the valves (110). The valve body (105) also has windows or openings (125), which provide complete flushing of the swivel hinge mechanism (130, 200, and 300), as well as the flaps (110). The new flaps (110) are similar to an aerodynamic profile that has a complex S-shaped curvature of its outer surface. This new geometry in combination with the location of the axis of rotation ensures that the flap (110) tends to turn to the closed position. Thus, the flap (110) begins to close earlier than the conventional mechanical flap, and closes before changing the direction of flow, similar to the work of a natural valve. The international application was published along with an international search report.
