    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 illustrative stent may comprise an elongated tubular member having a longitudinal axis, the elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with intermediate rung portions extending circumferentially between radially adjacent twisted knit stitches. Each twisted knit stitch may be interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The elongated tubular member may be configured to move between a collapsed configuration and an expanded configuration, wherein in the collapsed configuration the series of linked stitches form longitudinal columns and in the expanded configuration the series of linked stitches extend helically around the elongated tubular member.
