A stent formed in a tubular member, comprising a plurality of annular members (1) longitudinally arranged to hold an organic lumen in a patent state and one or a plurality of connection elements (2) connecting longitudinally adjacent annular members (1) and (1) to each other. Each of the annular members (1) further comprises a plurality of first annular member elements (11) and second annular member elements (12) continued to each other in the circumferential direction, and is extendable in the radial direction. Since the stent is soft, excellent in the follow-up capability to the lumen, and accordingly allowed to pass through the three-dimensionally meandering lumen, a shortening is not substantially produced and, in addition, a lateral hole can be formed.
L'invention concerne un stent formé dans un élément tubulaire et comprenant une pluralité d'éléments annulaires (1) disposés de manière longitudinale, afin de supporter une lumière organique dans un état persistant, et un ou plusieurs éléments de connexion (2) reliant de manière longitudinale des éléments annulaires adjacents (1 et 1) l'un à l'autre. Chaque élément annulaire (1) comprend également une pluralité de premiers éléments (11) et de seconds éléments (12) en continu les uns avec les autres dans le sens circonférentiel et est extensible dans le sens radial. Etant donné que le stent est lisse, possède une excellente capacité de suivi vers la lumière et, par conséquent, peut passer à travers la lumière méandrique tridimensionnelle, un raccourcissement n'est pas sensiblement produit et, de plus, un trou latéral peut être formé.
