    • A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.
    • 公开了一种包括多个间隔开的带状元件和相交连接件的可径向扩张的支架。 带状元件具有大致蛇形结构,以向每个带状元件提供大致正弦曲线的连续波。 波的特征在于沿着圆柱体大致纵向方向的多个峰和谷,使得当支架从第一直径扩展到第二直径时,带状元件中的波浪打开。 交叉连接件基本上为U形并终止在第一和第二柄部中。 链节的第一柄从带状元件上的峰和谷之间的区域发出,并且链节的第二柄从相邻带状元件上的峰和谷之间的区域发出。

    • The present invention is directed toward a stent having a plurality of axially spaced serpentine bands, each serpentine band having an axis circumferentially oriented around the longitudinal axis of the stent. The serpentine bands have a plurality of struts spaced along the axis of the serpentine band forming alternating peaks and troughs. The serpentine bands are interconnected via a plurality of interconnecting struts to form a plurality of cells defined by axially adjacent serpentine bands and circumferentially adjacent interconnecting struts. When the stent is in its unexpanded state, each serpentine comprises a plurality of slits, each slit being non-linear and continuous from a first end to a second end and being formed in at least a portion of each of three consecutively connected struts. Upon expansion of the stent to its expanded state, each of the slits expands in size to form an intra-columnar cell (ICC).
    • 本发明涉及具有多个轴向间隔的蛇形带的支架,每个蛇形带具有围绕支架的纵向轴线周向取向的轴线。 蛇形带具有沿着蛇形带的轴线间隔开的多个支柱,形成交替的峰谷。 蛇形带通过多个相互连接的支柱互连,以形成由轴向相邻的蛇形带和周向相邻的互连支柱限定的多个电池。 当支架处于其未膨胀状态时,每个蛇形管包括多个狭缝,每个狭缝从第一端到第二端是非线性的并且连续的,并且形成在三个连续连接的支柱中的每一个的至少一部分中。 在将支架膨胀到其膨胀状态时,每个狭缝的尺寸都扩大以形成柱内电池(ICC)。
