Title (EN) HEART VALVE PROSTHESIS
(FR) PROTHESE DE VALVULE CARDIAQUE
Abstract:
(EN) A bileaflet heart valve prosthesis has two leaflets (2, 3) which are pivotally mounted in an annular housing (1). The leaflets are pivotable between a closed position and an open position in which the flow of blood through the valve is substantially unrestricted. Pivot formations (4, 5) are provided on respective leaflets and are movable, in respective pivot seats (6, 7) provided in the annular housing, in the direction of blood flow. The upstream facing surface defined by the leaflets (2, 3) in their closed position is concave and smoothly curved in two mutually perpendicular directions.
(FR) Prothèse de valvule cardiaque à deux lames (2, 3) montées dans une structure annulaire de façon à pouvoir y pivoter (1). Les deux lames peuvent pivoter entre une position fermée et une position ouverte. Dans cette dernière, le sang afflue librement par la valvule. Des pivots (4, 5) amovibles sont montés sur chaque lame dans des logements (6, 7) ménagés sur la structure annulaire, dans le sens du flux sanguin. La surface côté antérieur délimitée par les lames (2, 3) en position fermée est concave et doucement incurvée en deux directions réciproquement perpendiculaires.
