    • The invention relates to a stent having a unitary structure and having a principal axis (1a) and a sucession of axially aligned tubular stages (10, 20, 30...), at least some of those stages being defined by a regular pattern having consecutive loops (40, 60, ...) closed on themselves, with a succession of hairpin-shaped apices (3, 4, 5, 6, ...) which are connected consecutively, in pairs, by a branch (15, 17, ...), each branch having two inflexion points (15a, 15b, ...) defining a double inflexion region (19), the loops being arranged in phase from one stage to an adjacent stage and being connected to one another by connecting bars (21) linking the apex region of a loop of a given stage to the region (19) of the inflexion points of a loop corresponding to it axially, in a preceding stage or in a following stage, in an alternating manner on the perimeter of said given stage.
    • 本发明涉及具有整体结构并具有主轴(1a)和轴向对齐的管状台(10,20,30 ...)的成套部件的支架,这些台中的至少一些由具有规则图案 连续的环(40,60,...)闭合在它们自身上,连续的发夹形顶点(3,4,5,6,...)成对地由分支(15, ...),每个分支具有限定双重拐点区域(19)的两个拐点(15a,15b,...),所述环从一个阶段到相邻阶段同相地布置并且彼此连接 通过将连接给定台的环的顶点区域的杆(21)在前一级中或在随后的级中以交替的方式连接到与轴向对应的环的拐点的区域(19) 所述给定阶段的周界。
