Title (EN) STENT DESIGN WITH STRUTS OF VARIOUS ANGLES AND STIFFNESS
(FR) MODÈLE DE STENT AVEC DES ENTRETOISES PRÉSENTANT DES ANGLES ET UNE RIGIDITÉ DIFFÉRENTS
Abstract:
(EN) The present invention is directed to stent that has a plurality of axially spaced serpentine bands. Each serpentine band comprises a plurality of struts, wherein adjacent struts are connected to each other forming a plurality of peaks and valleys the plurality of struts comprise a plurality of adjacent pairs of struts, wherein each adjacent pair of struts comprises a first strut and a second strut and wherein the first and second struts have a first end, a second end and a length and a plurality of interconnecting struts axially connect the serpentine bands. The stent further includes a plurality of a connector nodes, wherein a plurality of first and second struts that are associated with a connector node have a greater stiffness than a plurality of struts that are not associated with a connector node.
(FR) La présente invention concerne un stent possédant une pluralité de bandes ondulées espacées dans la direction axiale. Chaque bande ondulée comprend une pluralité d'entretoises, les entretoises adjacentes étant raccordées les unes aux autres formant une pluralité de pics et de vallées ; la pluralité d'entretoises comprend une pluralité de paires adjacentes d'entretoises, chaque paire adjacente d'entretoises comprenant une première entretoise et une seconde entretoise et les première et seconde entretoises ayant une première extrémité, une seconde extrémité et une longueur et une pluralité d'entretoises d'interconnexion raccordant dans la direction axiale les bandes ondulées. Le stent comprend, en outre, une pluralité de nœuds de connexion, une pluralité de première et de seconde entretoises associées à un nœud de connexion ayant une rigidité supérieure à celle d'une pluralité d'entretoises qui ne sont pas associées à un nœud de connexion.
