(FR) FEUILLETS PLIANTS DESTINÉS À DES VALVULES CARDIAQUES PROTHÉTIQUES
Abstract
(EN)
A prosthetic heart valve may include an expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets disposed within an interior region of the stent and attached to at least one of the cuff or the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a primary leaflet material, as well as features that reinforce specific regions of the leaflet.

Une valvule cardiaque prothétique peut comprendre un stent expansible, un manchon fixé à une partie annulaire du stent et une pluralité de feuillets disposés à l'intérieur d'une région interne du stent et fixés au manchon, au stent ou aux deux. Le stent peut avoir une pluralité de cellules reliées les unes aux autres dans une pluralité de rangées annulaires autour du stent. Les feuillets peuvent avoir ensemble une position de coaptation occluant la région interne du stent et une position ouverte dans laquelle la région interne n'est pas occluse. Chaque feuillet peut comprendre un matériau de feuillet primaire, ainsi que des caractéristiques qui renforcent des régions particulières du feuillet.
