Title (EN) ADAPTIVE HEART VALVE PROSTHESIS
(FR) PROTHÈSE DE VALVE CARDIAQUE ADAPTABLE
(ZH) 一种自适应的心脏瓣膜假体
Abstract: front page image
(EN) An adaptive heart valve prosthesis (100, 200, 300, 400, 500), comprising a stent (110, 210, 310) and a prosthetic valve (120, 520); the stent comprises a leak-proof ring (111, 211, 311, 411, 511) and a valve seaming section (112, 212, 312, 412, 512, 612), the leak-proof ring (111, 211, 311, 411, 511) and the valve seaming section (112, 212, 312, 412, 512, 612) are connected to each other; the prosthetic valve (120, 520) is fixedly connected to the valve seaming section (112, 212, 312, 412, 512, 612), at least a part of the valve seaming section (112, 212, 312, 412, 512, 612) is positioned between self-body heart valve leaves of a patient, on a cross section perpendicular to a central axis of the prosthetic valve (120, 520); the cross-sectional area of the valve seaming section (112, 212, 312, 412, 512, 612) is smaller than the cross-sectional area of a self-body heart valve ring of the patient, such that the valve seaming section (112, 212, 312, 412, 512, 612) does not directly radially expand the self-body heart valve ring of the patient; in a free state, the cross-sectional area of ​​the leak-proof ring (111, 211, 311, 411, 511) is larger than the cross-sectional area of ​​the self-body heart valve ring of the patient, and the leak-proof ring (111, 211, 311, 411, 511) can conform to the uneven contour of an atrial chamber wall or the self-body heart valve ring of the patient.
(FR) La présente invention concerne une prothèse de valve cardiaque adaptable (100, 200, 300, 400, 500), comprenant un stent (110, 210, 310) et une valve prothétique (120, 520). Le stent comprend un anneau anti-fuites (111, 211, 311, 411, 511) et une section de suture de valve (112, 212, 312, 412, 512, 612), l'anneau anti-fuites (111, 211, 311, 411, 511) et la section de suture de valve (112, 212, 312, 412, 512, 612) étant reliés entre eux. La valve prothétique (120, 520) est reliée à demeure à la section de suture de valve (112, 212, 312, 412, 512, 612), au moins une partie de la section de suture de valve (112, 212, 312, 412, 512, 612) étant positionnée entre des feuilles de valve cardiaque du corps d'un patient, sur une section transversale perpendiculaire à un axe central de la valve prothétique (120, 520). La surface de section transversale de la section de suture de valve (112, 212, 312, 412, 512, 612) est plus petite que la surface de section transversale d'un anneau de valve cardiaque du corps du patient, de sorte que la section de suture de valve (112, 212, 312, 412, 512, 612) ne dilate pas directement radialement l'anneau de valve cardiaque du corps du patient. Dans un état libre, la surface de section transversale de l'anneau anti-fuites (111, 211, 311, 411, 511) est plus grande que la surface de section transversale de l'anneau de valve cardiaque du corps du patient, et l'anneau anti-fuites (111, 211, 311, 411, 511) peut s'adapter au contour irrégulier d'une paroi de cavité auriculaire ou de l'anneau de valve cardiaque du corps du patient.
(ZH) 一种自适应的心脏瓣膜假体(100,200,300,400,500),包括支架(110,210,310)和人工瓣膜(120,520),支架包括防漏环(111,211,311,411,511)和瓣膜缝制段(112,212,312,412,512,612),防漏环(111,211,311,411,511)与瓣膜缝制段(112,212,312,412,512,612)相连,人工瓣膜(120,520)被固定连接在瓣膜缝制段(112,212,312,412,512,612)上,瓣膜缝制段(112,212,312,412,512,612)至少部分位于患者自体瓣叶之间,在垂直于人工瓣膜(120,520)中轴线的横截面上,瓣膜缝制段(112,212,312,412,512,612)的横截面积小于患者自体瓣膜瓣环的横截面积,使得瓣膜缝制段(112,212,312,412,512,612)不会直接径向扩张患者自体瓣膜瓣环,在自由状态下,防漏环(111,211,311,411,511)的横截面积大于患者自体瓣膜瓣环的横截面积,防漏环(111,211,311,411,511)能够顺应心房腔壁或患者自身瓣膜瓣环的不均匀轮廓。
