    • A serpentine coiled ladder stent is provided, in which the coil is formed from a wound strip of cells, wherein the sides of the cells are serpentine. Thus, the stent is comprised of a strip helically wound into a series of coiled windings, wherein the strip is formed of at least two side bands connected to each other, for example by a series of cross struts. Each side band is formed in a serpentine pattern comprising a series of bends, wherein upon expansion of the stent, the bends of the side bands open to increase the length of each of the individual cells in the helical direction, thereby lengthening the strip in the helical direction to allow the stent to expand without any significant unwinding of the strip.
    • 提供了蛇形盘绕的梯形支架,其中线圈由伤口的细胞条形成,其中细胞的侧面是蛇形的。 因此,支架由螺旋形地卷绕成一系列线圈绕组的带组成,其中条带由至少两个彼此连接的侧带形成,例如通过一系列交叉支柱。 每个边带以包括一系列弯曲部的蛇形图案形成,其中在支架膨胀时,侧带的弯曲部被打开以增加每个单个细胞在螺旋方向上的长度,从而使条带在 螺旋方向以允许支架膨胀而没有带的任何显着的退绕。
