摘要： A stent graft for transluminal implantation includes a resilient tubular interbraided latticework of metal or polymeric monofilaments, a tubular interbraided sleeve of polymeric multifilament yarns, and an adhesive layer between the sleeve and latticework for bonding them together. The monofilaments and multifilament yarns are arranged in respective sets of axially spaced apart and oppositely directed helices, concentric on a common axis of the stent graft. The respective braid angles of the monofilaments and multifilament yarns are carefully matched to ensure that the latticework and sleeve behave according to substantially the same relationship governing the amount of radial reduction that accompanies a given axial elongation. According to a process for fabricating the stent graft, the latticework and sleeve are braided and thermally set independently, then bonded to one another by a silicone polymer adhesive applied evenly to the latticework in a liquid spray that also incorporates an organic solvent. Especially preferred yarns are composed of essentially untwisted filaments that define non-circular yarn cross sections. Alternative stent graft constructions feature exterior and interior sleeves on opposite sides of the latticework, two or more sleeves axially spaced from one another on the same latticework, a latticework formed of a recovery metal, and a plastically deformable latticework.

摘要： A prothesis for transluminal implantation consists of a flexible tubular three-dimensionally braided structure of metal or polymeric monofilaments, and polymeric multifilament yarns. The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced apart helices, concentric on a common central axis of the prosthesis. The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide one or more layers of sheeting that reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft. An alternative embodiment prosthesis includes elastically and plastically deformable structural strands, selectively plastically deformed by cold working, then three-dimensionally braided to form the prosthesis.

摘要： A stent for placement in a body lumen is fabricated by forming a tube having an un-deployed diameter sized for the tube to be placed on a deployment balloon and advanced through a body lumen to a deployment site. The tube is expandable upon inflation of the balloon to an enlarged diameter sized for the tube to be retained within the lumen at the site upon deflation and withdrawal of the balloon. The tube has a stent axis extending between first and second axial ends of the tube. The tube has an exterior surface and an interior surface. The tube is polished to polish the exterior surface to a smooth surface finish and with at least a portion of the interior surface having a rough surface finish rougher than the surface finish of the exterior surface.

摘要： The present disclosure relates to an intraluminal stent including a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. When the tube is at the un-deployed diameter, the tube has cell-defining portions with opposing surfaces defining an open cell bounded by the cell-defining portions. The cell has a major axis and a minor axis. The cell-defining portions include first and second longitudinal segments each having a longitudinal axis extending parallel to and positioned on opposite sides of the cell major axis. The longitudinal segments have an undulating pattern to define a plurality of peaks and valleys spaced outwardly and inwardly, respectively, from the longitudinal axes. The first and second longitudinal segments are interconnected at opposite ends.

摘要： A bifurcated stent graft implantable in branched internal passageways includes an open-frame stent latticework formed of helically wound structural strands, and a graft sleeve formed of interwoven textile strands. The sleeve is substantially impervious to fluids and is adjustable along with the graft between a nominal state and radially-reduced axially-elongated state, according to substantially the same relationship of radial reduction versus axial elongation. The sleeve and stent are bonded to one another at least at proximal and distal end regions of the stent graft. The sleeve preferably is surrounded by the stent, and incorporates a flow dividing feature in the form of an axially extending seam. The seam brings together portions of the sleeve that otherwise would be circumferentially spaced apart in the tubular sleeve shape. The stent latticework and graft sleeve can be coextensive, the sleeve can extend distally beyond the latticework, or the latticework can extend proximally beyond the sleeve, depending on the intended use. In other alternative embodiments, the sleeve can surround the latticework.

摘要： The expandable stent-graft generally defines a cylindrical lumen made from a stent having a discontinuous wall that is at least substantially covered with an expanded polytetrafluoroethylene material. The expanded polytetrafluoroethylene covering may be a biaxially oriented, expanded polytetrafluoroethylene material having nodules and longitudinal and circumferential fibrils or a uniaxially oriented, expanded polytetrafluoroethylene material. The expandable stent-graft expands and compresses in association with the stent structure as it is contracted and expanded.
