摘要： A stent (30) formed from cannula and having flexible segments (31) and high hoop strength segments (32) alternating therealong. Longitudinal struts or tie bars (41) interconnect the segments. Minimal length reduction of the strut occurs upon expansion. In the high hoop strength segment (32), struts (37) in a zig-zag configuration (Gianturco Z-stent) are initially parallel in the unexpanded strut condition. In the flexible segment (31), struts (58) extend from a respective C shaped bend (59) to converge at the opposite ends thereof when unexpanded. In one embodiment, certain adjacent struts (39-41) of the hoop segment are spaced apart by elongated openings or gaps (46, 48) interposed therebetween and interconnected at their respective ends (42, 44) to form a T-shaped strut interconnection (45). The selected width (50, 51) of the first and third struts (54, 57) increases toward the ends (47, 48) of the elongated openings (46, 48) adjacent the strut interconnection (45). This strut width increase about one end of the strut significantly reduces the tensile strain exhibited about the opening end when the stent is radially expanded during manufacture. The tip length (52, 55) of the struts about the interconnection (45) is also adjusted (increased) along with the other C-shaped strut interconnections (59, 71) to further distribute the tensile strain developed during radial expansion.
摘要翻译：支架（30）由插管形成并且具有柔性片段（31）和沿其交替的高环箍强度片段（32）。纵向支柱或连杆（41）将这些部分互连。扩张时最小长度减少。在高箍强度段（32）中，呈Z字形构造的支柱（37）（Gianturco Z-支架）最初平行于未膨胀支柱状态。在柔性部分（31）中，当未扩张时，支柱（58）从相应的C形弯曲部（59）延伸以会聚在其相对端处。在一个实施例中，箍段的某些相邻支柱（39-41）由插入其间的细长开口或间隙（46,48）间隔开并且在其相应端部（42,44）处互连以形成T形支柱互连（45）。第一和第三支柱（54,57）的选定宽度（50,51）朝向邻近支柱互连（45）的细长开口（46,48）的端部（47,48）增大。当支架在制造期间径向膨胀时，围绕支杆的一端的该支杆宽度增加显着减小了关于开口端所展现的拉伸应变。围绕互连（45）的支柱的尖端长度（52,55）也与其他C形支柱互连（59,71）一起被调整（增大），以进一步分布在径向膨胀期间产生的拉伸应变。 p>
