摘要： A stent (10) formed from cannula and having flexible segments (11) and high hoop strength segments (12) alternating therealong. Axial tie bars (21, 22) interconnect the segments; minimal length reduction would occur upon expansion. In the high hoop strength segment (12), struts (16) are initially parallel in the unexpanded strut condition, while in the flexible segment (11), struts (14) extend from a respective bight (15) to converge at distal ends when unexpanded. In one embodiment, certain adjacent struts (16) of the hoop segment are spaced apart by a large gap (20) while others are spaced apart by a small gap (18). In another embodiment all the struts (16) of the hoop segment are spaced apart uniformly from each other (or from an axial tie bar) by a small gap (23), resulting in minimizing the occurrence of fatigue of high-stress sites upon expansion/contraction cycles from continuous pulsatile events.

摘要： PROBLEM TO BE SOLVED: To provide a stent having a high strength and flexibility in the radial direction which endures pulsatile expansion/contraction. SOLUTION: The stent is formed from a cannula and has flexible segments 11 and high hoop strength segments 12 alternately. Axial tie bars interconnect the segments, and length reduction upon expansion is minimized. In the unexpanded condition, struts in the high hoop strength segment are parallel while struts in the flexible segment extend from a bent part and converge at the other end. In one embodiment, certain adjacent struts in the hoop segment are spaced apart by a large gap while other struts are spaced apart by a small gap. In another embodiment, struts in the hoop segment are spaced apart uniformly by a medium gap. By this, the occurrence of metal fatigue of high-stress sites is minimized upon expansion/contraction cycles from continuous pulsatile events. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：提供一种具有高径向强度和柔韧性的支架，其支持脉动扩张/收缩。解决方案：支架由插管形成，并且具有交替的柔性段11和高箍强度段12。轴向连接杆互连片段，并且在膨胀时减小长度被最小化。在未膨胀的条件下，高箍筋段中的支柱平行，而柔性段中的支柱从弯曲部分延伸并在另一端收敛。在一个实施例中，环箍段中的某些相邻的支柱间隔开大间隙，而其他支柱间隔开一小间隙。在另一个实施例中，环形段中的支柱通过介质间隙均匀间隔开。由此，在连续脉动事件的膨胀/收缩循环中，高应力部位的金属疲劳的发生被最小化。版权所有（C）2009，JPO＆INPIT

摘要： A radially expandable stent (10) made from a cannula or sheet of biocompatible material that includes at least one longitudinal segment (14) comprised of a series of laterally interconnected closed cells (13). Each closed cell of a longitudinal segment is defined laterally by a pair of longitudinal struts (15, 16) that are interconnected at each end by a circumferentially adjustable member (19, 20). When the stent is expanded using a balloon (47), the opposing circumferentially adjustable members deform to allow circumferential expansion of the longitudinal segment, while the length of the segment, as defined by the longitudinal struts, is maintained. Self-expanding versions of the stent utilize a nickel-titanium alloy. Adjacent longitudinal segments are joined by flexible interconnection segments (21) that permit the stent to bend laterally. The flexible interconnection segment is comprised of curvilinear struts (22, 23) that form a series of serpentine bends (81) that distribute lateral bending forces. In a preferred embodiment, a short strut interconnects longitudinal segments and an adjacent interconnection segment. Each interconnection strut attaches to the longitudinal segment within a region (27) at the end (17) of a longitudinal strut (15) dividing two adjacent closed cells.
