    Abstract: A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, the plurality of cells defining an elongated tube with a lumen running therethrough. The elongated tube has first, second, and third sections, the first section having a substantially first diameter and the third section having a substantially constant second diameter that is larger than the substantially constant first diameter of the first section, wherein the diameter of the second section transitions from the first diameter to the second diameter. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second and third sections. In the second section, the plurality of intersecting elongated members includes a plurality of pairs of elongated members, wherein each pair of elongated members includes two adjacent elongated members twisted axially around each other.

    Abstract: A delivery system for a stent graft may include a stent graft having a proximal end, a distal end, an internal lumen between the proximal end and the distal end, a graft material tube, a graft material sidewall and a plurality of longitudinally spaced apart self-expanding stents attached to the graft material sidewall; a guidewire catheter extending longitudinally through the lumen of the stent graft; and a wire extending longitudinally along only a first side of the graft material tube in an undulating pattern of successive curves in alternate directions, the wire repeatedly extending through the graft material sidewall from inside the graft material tube to outside the graft material tube such that a portion of the wire extends over the guidewire catheter along a longitudinal length of the guidewire catheter to secure the guidewire catheter at least partially to an internal wall of the stent graft.

    Abstract: The disclosure is directed to a continuous stitch wire routing and delivery system. The system includes a transitional stitching on a tube of a stent graft. The transitional stitching includes a distal portion stitching and a proximal portion stitching. A portion of each stitch loop of the stitches of the transitional stitching is disposed outside the tube and having a string passing through the stitch loop. A distal portion of the string passes through stitch loops of the distal portion stitching, a middle portion of the string is circumferentially around the tube, and a proximal portion of the string passes through stitch loops of the proximal portion stitching. The stent graft is in a compressed state when a tension of the string is above a high-tension threshold. The stent graft is in an expanded state when the tension is below a low-tension threshold.

    Abstract: A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, which define an elongated tube with a lumen. The elongated tube has first and second sections, the first section having a substantially constant first diameter, the second section having a substantially constant second diameter that is larger than the first diameter. The elongated tube also has a transition section between the first and second sections, the transition section having a concave curvature extending proximally from the first section and a convex curvature extending proximally from the concave curvature to the second portion. A proximal end of the second section has a plurality of rounded ends formed by the plurality of intersecting elongated members. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second section.
