    • A intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. The tube includes a structural beam extending between first and second ends. The structural beam changes from a first geometry to a second geometry when the tube changes from the un-deployed diameter to the enlarged diameter. The structural beam includes first and second longitudinal elements each extending at least partially between the first and second ends and with a spacing between the first and second elements. Each of said first and second elements changes from the first geometry to the second geometry when the tube changes from the un-deployed diameter to the enlarged diameter for the spacing to remain substantially unchanged as the tube changes from the un-deployed diameter to the enlarged diameter.
    • 管腔内支架包括具有未展开直径并且可扩张至扩大直径的网状管。 管包括在第一和第二端之间延伸的结构梁。 当管从未展开的直径变大到扩大的直径时,结构梁从第一几何变化到第二几何形状。 结构梁包括第一和第二纵向元件,每个第一和第二纵向元件至少部分地在第一和第二端之间延伸并且在第一和第二元件之间具有间隔。 当管从未展开的直径改变到扩大的直径时,所述第一和第二元件中的每一个从第一几何形状变化到第二几何形状,以使间隔保持基本上不变,因为管从未展开的直径变大到扩大的直径 直径。
