Title
(EN) TRANSCATHETER PULMONARY BALL VALVE ASSEMBLY
(FR) ENSEMBLE VALVULE À BILLE PULMONAIRE PAR TRANS-CATHÉTER
Abstract
(EN)
A heart valve assembly has a frame comprising an anchoring section, a generally cylindrical leaflet support section, and a neck section that transitions between the anchoring section and the valve support section. The anchoring section has a ball- shaped configuration defined by a plurality of wires that extend from the leaflet support section, with each wire extending radially outwardly to a vertex area where the diameter of the anchoring section is at its greatest, and then extending radially inwardly to a hub. A plurality of leaflets are stitched to the leaflet support section. The heart valve assembly is delivered to the location of a native pulmonary trunk, the vertex area of the anchoring section is deployed into the native pulmonary arteries such that the vertex area is retained in the pulmonary arteries, and then the leaflet support section is deployed in the pulmonary trunk.

L'invention concerne un ensemble valvule cardiaque qui possède un cadre comportant une section d'ancrage, une section de support de feuillet généralement cylindrique, et une section de col qui effectue une transition entre la section d'ancrage et la section de support de valvule. La configuration de la section d'ancrage est une forme de bille définie par une pluralité de fils qui s'étendent depuis la section de support de feuillet, chaque fil s'étendant radialement vers l'extérieur vers une zone de sommet où le diamètre de la section d'ancrage est à son maximum, puis s'étendant radialement vers l'intérieur vers un moyeu. Une pluralité de feuillets sont cousus à la section de support de feuillet. L'ensemble valvule cardiaque est posé à l'emplacement d'un tronc pulmonaire natif, la zone de sommet de la section d'ancrage est déployée dans les artères pulmonaires natives, de telle sorte que la zone de sommet est retenue dans les artères pulmonaires, puis la section de support de feuillet est déployée dans le tronc pulmonaire.
