摘要:
A modular stent comprises at least one stent module including an intermediate segment consisting of one of either a closed-cell segment or a Z-segment and a pair of end segments connected to respective longitudinal ends of said intermediate segment, each end segment consisting of the other of said closed-cell segment or Z-segment, each closed-cell segment consisting solely of at least one annular closed-cell ring and each Z-segment consisting solely of at least one annular Z-ring. A method of manufacturing a stent from a small diameter tube includes laser-cutting the small diameter tube to define a plurality of longitudinally adjacent Z-rings, providing interconnector portions of said tube integrally joining facing aligned or offset Z-rings, expanding the small diameter tube, and removing predetermined interconnector portions from the expanded tube to provide the predetermined desired arrangement of interconnected closed-cell rings and Z-rings
