Title
(EN) MECHANICAL HEART VALVE PROSTHESIS FOR THE RIGHT VENTRICLE
(FR) PROTHÈSE DE VALVULE CARDIAQUE MÉCANIQUE POUR LE VENTRICULE DROIT
Abstract
(EN)
A prosthetic heart valve (11) having a pair of cooperating leaflets (15) mounted in a valve body (13) to alternate between an open position where the flow of blood in a downstream direction is permitted and a closed position where the flow of blood in the reverse direction is counteracted. Pivot member sets at diametrically opposite sides of each leaflet guide the leaflets moving between the open and closed positions, each set including an ear (41) or a recess (141) cooperating with an associated cavity (25) or knob (125) of an interior surface of the valve body. Each ear or recess bounds at least one leaflet passageway (76, 77, 176) through that ear or recess and located spaced from upstream and downstream ends of the ear for allowing flow through that ear and the associated cavity, or through that recess, when the leaflets are in the closed positions.
(FR)
Valvule cardiaque prothétique (11) comportant une paire de feuillets (15) coopérants montés dans un corps de valvule (13) pour alterner entre une position ouverte dans laquelle l'écoulement de sang dans une direction aval est permis et une position fermée dans laquelle l'écoulement de sang dans la direction inverse est contrecarré. Des ensembles d'éléments de pivotement au niveau de côtés diamétralement opposés de chaque feuillet guident le déplacement entre les positions ouverte et fermée, chaque ensemble comprenant une oreille (41) ou un évidement (141) coopérant avec une cavité (25) ou une saillie (125) associées d'une surface intérieure du corps de valvule. Chaque oreille ou évidement délimite au moins un passage (76, 77, 176) de feuillet à travers cette oreille ou cet évidement et est situé à une certaine distance des extrémités amont et aval de l'oreille pour permettre un écoulement à travers cette oreille et la cavité associée, ou à travers cet évidement, lorsque les feuillets sont dans la position fermée.
