    摘要： A stent comprises a plurality of connected serpentine circumferential bands. Adjacent serpentine circumferential bands are connected via a plurality of longitudinal connectors extending between peaks on one serpentine circumferential band and troughs on the serpentine circumferential band adjacent thereto. The struts of the serpentine bands are arranged such that on expansion of the stent, peaks and troughs which are substantially circumferentially aligned with one another, but not connected with one another, on adjacent serpentine circumferential bands are circumferentially displaced from one another.

    摘要： In at least one embodiment, a stent comprises a plurality of serpentine bands and a plurality of connector struts. Adjacent serpentine bands are connected by at least one connector strut. Each serpentine band comprises a plurality of alternating straight band struts and turns. Each connector strut is connected at one end to a turn of one serpentine band and connected at the other end to a turn of another serpentine band. The turns of a serpentine band comprise connected turns that connect to a connector strut and unconnected turns that do not connect to a connector strut. At least one of the serpentine bands comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed.

    摘要： A multi-section filamentary stent comprises a braided section, which is a cylindrical mesh of a first set of filaments, connected to at least one wound section comprising a second set of one or more filaments having a repeating configuration with a bent portion. The two sections are preferably connected by at least one continuous filament extending into both sections. The two sections may be connected by a weld, a suture, a common graft, an overlapping portion of the two sections, or one or more filaments of one section looping through portions of the other section. The stent may comprise a first section, having a braided first stent architecture with a first flexibility and a first radial force, and a second section, having a non-braided second stent architecture with a second flexibility less than the first flexibility and a second radial force greater than the first radial force, in which at least one continuous filament is integral to both the first and second sections. The stent may have a radially compressed configuration and a radially expanded configuration, in which the first section has a first shortening ratio, and the second section has a second shortening ratio less than the first shortening ratio. Such multi-section stents may comprise modular components of a modular stent, such as a bifurcated modular stent, adapted for joining together in situ. The multi-section stent may comprise a first section having a first percentage of open area and a second section having a second percentage of open area. The stent may also comprise a first section having a first stent architecture with an end effect wherein the radial strength at the end is less than elsewhere in the stent, and a second section having a second stent architecture to counteract the end effect. Methods for treating body lumen by implanting the stents as described herein are also disclosed, as is a method for counteracting a stent architecture end effect.

    摘要： An introducer deploys an endoluminal device in a distal location from a proximal location. The introducer comprises a retrograde portion, an anterograde portion axially moveable relative to the retrograde portion, a shaft having a distal tip and an anterograde sheath attached to the distal tip, and anchoring means in at least one of the retrograde portion or the anterograde portion for anchoring the device during deployment from its proximal end to its distal end. An inner sheath may be mounted concentrically over the shaft with the endoluminal device mounted concentrically over the inner sheath. The anchoring device may comprise an inflatable balloon mounted radially inside the retrograde portion, a tether, or an extended portion of the endoluminal device confined by a notch in the interface of two sheaths in the retrograde portion of the introducer, or may comprise a holder in the anterograde portion.
