(JA) ステント
Abstract:
(EN) Provided is a stent which can be smoothly removed from the body and has bridge parts that are less likely to kink. This stent 10 has strut parts 30 and bridge parts 40. All peaks 35 of the strut parts are joined to the bridge parts 40, and the bridge parts 40 bundle multiple peaks 35 together and join the peaks 35 and valleys 37 of strut parts 30 adjacent thereto on one side. The bridge parts 40 have bonding parts 50 formed as a result of the bridge parts 40 being bundled into a single bundle midway towards the one side. The bonding parts 50 are joined to valleys 37 of strut parts 30 adjacent on the one side, and have two curved parts 51, 53 which are curved in one circumferential direction and the other circumferential direction of the stent. The curved parts are formed such that all peaks 52, 54 thereof are directed to the other side.
(FR) L'invention concerne une endoprothèse vasculaire qui peut être retirée sans à-coups du corps et comporte des pièces de liaison qui sont moins susceptibles de se plier. L'endoprothèse vasculaire (10) selon l'invention comporte des pièces de type entretoise (30) et des pièces de liaison (40). Tous les sommets (35) des pièces de type entretoise sont reliés aux pièces de liaison (40), et les pièces de liaison (40) rassemblent de multiples sommets (35) et relient les sommets (35) et les creux (37) de pièces de type entretoise (30) adjacentes à celles-ci d'un côté. Les pièces de liaison (40) comportent des pièces d'assemblage (50) formées du fait du rassemblement des pièces de liaison (40) en un seul faisceau à mi-chemin en direction dudit côté. Les pièces d'assemblage (50) sont reliées à des creux (37) de pièces de type entretoise (30) adjacentes dudit côté, et comportent deux pièces incurvées (51, 53) qui sont incurvées dans une direction circonférentielle et l'autre direction circonférentielle de l'endoprothèse vasculaire. Les pièces incurvées sont formées de telle sorte que tous les sommets 52, 54 de celles-ci sont dirigés vers l'autre côté.
(JA) ステントを体内からスムーズに抜き出し可能で、ブリッジ部がキンクしにくい、ステントを提供する。このステント10は、ストラット部30とブリッジ部40とを有し、各ストラット部の山部35が、全てブリッジ部40に連結され、かつ、ブリッジ部40により複数束ねられて、一端側に隣接するストラット部30の谷部37に連結され、ブリッジ部40は、一端側に向かう途中で一本に束ねられてなる結束部50を有し、この結束部50が、一端側に隣接するストラット部30の谷部37に連結され、結束部50は、ステントの周方向一方向及び周方向他方向に屈曲する、2つの屈曲部51,53を有しており、各屈曲部の全ての頂部52,54が他端側に向くように構成されている。
