Title (EN) HEART VALVE PROSTHESIS
(FR) PROTHÈSE DE VALVULE CARDIAQUE
(ZH) 一种心脏瓣膜假体
Abstract:
(EN) Provided is a heart valve prosthesis (100, 200, 300, 400) comprising a stent (110, 210, 310, 410) and a prosthetic valve (120, 220, 420). The stent (110, 210, 310, 410) comprises an atrial segment (111, 211, 311, 411) and a valve sewn segment (112, 212, 312, 412). The prosthetic valve (120, 220, 420) is fixedly attached to the valve sewn segment (112, 212, 312, 412). A skeleton of a distal portion of the valve sewn segment (112, 212, 312, 412) extends to form a supporting segment (113, 213, 313, 413). The supporting segment (113, 213, 313, 413) is integrally formed with the valve sewn segment (112, 212, 312, 412), and one end of the atrium segment (111, 211, 311, 411) is connected to a distal portion of the supporting segment, the other end of the atrial segment (111, 211, 311, 411) is free, and in a cross-section perpendicular to an axis of the prosthetic valve (120, 220, 420), a valve sewing segment (112, 212, 312, 412) is located in the support segment (113, 213, 313, 413), and a center of the valve sewing segment (112, 212, 312, 412) does not coincide with the center of the supporting segment (113, 213, 313, 413). A cross-sectional area of the supporting segment (113, 213, 313, 413) is greater than the cross-sectional area of the valve sewing segment (112, 212, 312, 412). The cross-sectional area of the atrial segment (111, 211, 311, 411) is greater than the cross-sectional area of the supporting segment (113, 213, 313, 413). The cross-sectional area of the valve sewing segment (112, 212, 312, 412) is less than the cross-sectional area of a patient's autogenous valve annulus. The supporting segment (113, 213, 313, 413), in a free state, is at least partially positioned between the patient's autogenous valve annulus (280).
(FR) L'invention concerne une prothèse de valvule cardiaque (100, 200, 300, 400) comprenant un stent (110, 210, 310, 410) et une valve prothétique (120, 220, 420). Le stent (110, 210, 310, 410) comprend un segment auriculaire (111, 211, 311, 411) et un segment de suture de valve (112, 212, 312 412). La valve prothétique (120, 220, 420) est fixée de manière fixe au segment de suture de valve (112, 212, 312 412). Un squelette d'une partie distale du segment de suture de valve (112, 212, 312, 412) s'étend pour former un segment de support (113, 213, 313, 413). Le segment de support (113, 213, 313, 413) est formé d'un seul tenant avec le segment de suture de valve (112, 212, 312, 412), et une extrémité du segment auriculaire (111, 211, 311, 411) est reliée à une partie distale du segment de support, l'autre extrémité du segment auriculaire (111, 211, 311, 411) est libre, et dans une section transversale perpendiculaire à un axe de la valve prothétique (120, 220, 420), un segment de suture de valve (112, 212, 312, 412) est situé dans le segment de support (113, 213, 313, 413), et un centre du segment de suture de valve (112, 212, 312, 412) ne coïncide pas avec le centre du segment de support (113, 213, 313, 413). Une surface de section transversale du segment de support (113, 213, 313, 413) est plus grande à la surface de section transversale du segment de couture de soupape (112, 212, 312, 412). La surface de section transversale du segment auriculaire (111, 211, 311 411) est plus grande à la surface de section transversale du segment de support (113, 213, 313, 413). La surface de section transversale de couture de valve (112, 212, 312, 412) est inférieure à la surface de section transversale de l'anneau de valve autogène du patient. Le segment de support (113, 213, 313, 413), dans un état libre, est au moins partiellement positionné entre l'anneau de valve autogène du patient (280).
