Title
(EN) PROSTHETIC HEART VALVE WITH PARAVALVULAR LEAK MITIGATION FEATURES
(FR) VALVULE CARDIAQUE PROTHÉTIQUE DONT LA CARACTÉRISTIQUES EST LA LIMITATION DE FUITES PARAVALVULAIRES
Abstract
(EN)
A prosthetic heart valve includes a collapsible and expandable stent (302, 402) and a valve assembly (140). A first cuff (306) is positioned on the lumenal or ablumenal surface of the stent. A second cuff (350, 550, 650) is positioned radially outward of the stent and the first cuff. The second cuff (650) may include apertures (653) that allow blood to pass through the second cuff into the spaces between the first and second cuffs. The second cuff (550, 550') may include a proximal edge (552) with notches (553, 553') that may be closed to create puckered areas (555, 555') in the second cuff to facilitate the movement of blood in the spaces between the first and second cuffs. The stent (402) may include struts (412c, 412d) adjacent the second cuff that bow inwardly to create space for blood to flow in the spaces between the two cuffs.
(FR)
L'invention porte sur une valvule cardiaque prothétique comprenant une endoprothèse pliable et extensible (302, 402) et sur un ensemble valvule (140). Un premier manchon (306) est situé sur la surface luminale ou abluminale de l'endoprothèse. Un second manchon (350, 550, 650) est radiale vers l'extérieur par rapport à l'endoprothèse et au premier manchon. Le second manchon (650) peut comprendre des ouvertures (653) qui permettent au sang de passer à travers le second manchon dans les espaces situés entre les premier et second manchons. Le second manchon (550, 550') peut comprendre un bord proximal (552) avec des encoches (553, 553') qui peuvent être fermées pour créer des zones froncées (555, 555') dans le second manchon pour faciliter le mouvement du sang dans les espaces situés entre les premier et second manchons. L'endoprothèse (402) peut comprendre des entretoises (412c,412d), adjacentes au second manchon, qui se penchent vers l'intérieur et créent un espace pour que le sang s'écoule dans les espaces entre les deux manchons.
