    摘要: An implantable stent and stent-graft for treating a patient having a relatively healthy first aorta portion upstream from a renal artery branch, and a diseased aorta portion downstream from the renal artery branch. One embodiment of the device includes a fixation section, a renal artery branch section and a diseased aorta section, all of which can be tubular, radially compressible and self-expandable structures formed from a plurality of filaments which are helically wound in a braided configuration. When the device is implanted and in its expanded state, the fixation section engages the first aorta portion upstream from a renal artery branch to provide substantial anchoring support. The diseased aorta section engages the portion of the aorta downstream from the renal artery branch and extends across the diseased portion of the aorta for purposes of treatment. The renal artery branch section extends across the renal artery branch and connects the diseased aorta section to the fixation section while allowing blood flow between the aorta and renal artery branch.

    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: In at least one embodiment, a stent comprises a plurality of serpentine bands and a plurality of connector columns. Each serpentine band comprises a plurality of alternating straight band struts and turns. Adjacent serpentine bands are connected across a connector column by a plurality of connector struts. 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 serpentine band comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. At least one serpentine band comprises a repeating pattern of three band struts and then one band strut extending between connected turns as the serpentine band is traversed.

    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.
