    • A cylindrical stent (10) for placement in a vessel of a human body. The stent has a longitudinal axis and in its formation includes circumferential arcs (12) and diagonal struts (14) having an intersection angle between the circumferential arcs (12) and the diagonal struts (14) within the range of 10 to 80 degrees when the stent (10) is in its non-deployed state. The diagonal struts (14) are joined by curved sections (18) to the circumferential arcs (12) which collectively form a closed perimeter cell. The closed perimeter cell has two parallel, circumferential arcs (12) located at the longitudinal extremeties of the closed perimeter cell and the circumferential arcs (12) lie generally perpendicular to the stent's longitudinal axis where the stent (10) may be deployed in a manner so that although the length of the stent (10) increases during deployment, at the nominal fully deployed diameter, the deployed stent (10) is substantially the same length as the non-deployed length.
    • 一种用于放置在人体容器中的圆柱形支架(10)。 支架具有纵向轴线,并且其形成包括圆周弧(12)和对角撑杆(14),其在圆周弧(12)和对角撑杆(14)之间具有在10至80度范围内的相交角度 支架(10)处于非展开状态。 对角支柱(14)通过弯曲部分(18)连接到共同形成封闭的周边细胞的周向圆弧(12)。 封闭的周边细胞具有位于封闭的周边细胞的纵向极端处的两个平行的周向圆弧(12),并且周向圆弧(12)大致垂直于支架的纵向轴线,其中支架(10)可以以 使得尽管支架(10)的长度在展开期间增加,但在标称的完全展开直径的情况下,所展开的支架(10)基本上与非展开长度相同的长度。
