    Abstract: A stent includes an elongated tubular member expandable from a radially collapsed configuration to a radially expanded configuration, the elongate tubular member including a first plurality of filaments extending in a first helical direction and a second plurality of filaments extending in a second helical direction, the first plurality of filaments extending in the first helical direction and the second plurality of filaments extending in the second helical direction overlapping to form a plurality of cells arranged in rows extending circumferentially about the elongated tubular member. At least some of the cells within one or more rows are adapted to provide increased flexibility to the stent.

    Abstract: An endoprosthesis configured to shift between a collapsed configuration and an expanded configuration may include a tubular scaffold formed from a single filament knitted about a central longitudinal axis and defining a length from a proximal end to a distal end, the tubular scaffold including a plurality of rows of loops and a plurality of rows of rungs arranged around the central longitudinal axis in an alternating fashion; and a polymeric covering extending along the tubular scaffold. Each row of loops and each row of rungs extends longitudinally along the tubular scaffold between the proximal end and the distal end. The tubular scaffold includes a first cutout region extending along a majority of the length of the tubular scaffold and a second cutout region extending along a majority of the length of the tubular scaffold. The polymeric covering is uninterrupted along the first cutout region and the second cutout region.

    Abstract: An endoprosthesis for implantation within a vessel lumen may include a tubular scaffold formed of one or more interwoven filaments, wherein the tubular scaffold is configured to shift between a radially collapsed configuration and a radially expanded configuration, a polymeric covering secured to the tubular scaffold, and an anti-migration element extending radially outward from the tubular scaffold. The anti-migration element extends helically along at least a portion of the length of the tubular scaffold in a first helical direction. The anti-migration element may include a wire extending along an outer surface of the tubular scaffold. The anti-migration element may include a second polymeric covering disposed over the wire.
