Title (EN) HEART VALVE WITH DISC OCCLUDER
(FR) VALVULE CARDIAQUE A OBTURATEUR A DISQUE
Abstract:
(EN) A heart valve prosthesis (10) which is suited for replacement of the aortic valve or mitral heart valve or any of the four valves in the heart. The invention includes a ring body portion (30) having a fluid flow bore (32) with an elliptical inner wall through which blood flows controlled by a disc occluder (44) supported between proximal and distal support struts (50, 52) having their ends attached to the metallic ring and coinciding with the curvature of the disc. The disc has a thickened outer edge (42) so that the disc allows blood flow through the opening in the ring by rotation and translation of the disc occluder, from a closed position in sealing engagement (35) around the ring body, to an open position wherein the thickened edge of the disc occluder (44) serves as a travel stop for translational movement of the occluder during operation.
(FR) Prothèse (10) de valvule cardiaque adaptée pour remplacer la valvule aortique ou la valvule cardiaque mitrale ou n'importe laquelle des quatre valvules dans le coeur. L'invention comprend une partie (30) de corps annulaire comportant un alésage (32) d'écoulement de fluide doté d'une paroi interne elliptique, au travers duquel s'écoule du sang régulé par un obturateur (44) à disque reposant entre des butées (50, 52) de support proximale et distale, dont les extrémités sont fixées à l'anneau métallique et coïncident avec la courbure du disque. Le disque comporte un bord externe (42) épaissi, de manière à ce que le disque permette à l'écoulement sanguin de passer à travers l'orifice situé dans l'anneau, par rotation et translation de l'obturateur à disque, à partir d'une position fermée en contact étanche (35) autour du corps annulaire jusqu'à une position ouverte dans laquelle le bord épaissi de l'obturateur (44) à disque sert d'arrêt de trajectoire au mouvement de translation de l'obturateur pendant le fonctionnement.
