摘要: A stent-graft comprising a stent and a graft having a supported portion lining or covering at least a portion of the stent, and an unsupported portion extending proximally beyond the proximal end of the stent. The stent-graft may have a length corresponding to at least a mean standard length from a standard incision point to a distal-most portion of a standard lumen into which the distal end of the stent is adapted to be deployed, with the unsupported portion of the graft extending beyond the mean standard length by an amount equal to at least two, if not three or more, standard deviations of the mean standard length. A method for deploying the stent-graft comprises making an incision in a wall of the lumen, introducing and deploying the stent-graft in the lumen so that the proximal end extends beyond the incision, and attaching the graft to a lumen by anastamosis.

摘要: A stent and method for making the stent are provided. The stent comprises regions of differing numbers of braided filaments to provide a stent with different dimensions and/or properties in different regions along the stent length. A preferred stent (10) comprises a first (11) and second plurality (12) of braided filaments each braided together. The second plurality of braided filaments is braided into the first plurality of braided filaments to form a region of different properties than the first. A preferred embodiment is a stent (100) having a narrower diameter along a more flexible region (110) and a broader diameter along a more rigid region (120). Also included is a method of constructing a braided stent in accordance with the above. The method comprises the steps of braiding a first plurality of filaments to form the flexible portion, combining a second plurality of filaments to the first plurality of filaments, and then braiding the second plurality of filaments with the first plurality of filaments to form the more rigid region from the combination of the first and second plurality of filaments, wherein the second plurality of filaments are braided only in the rigid region.
