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: A stent includes an expandable tubular body formed of one or more interwoven wires, and including a plurality of anti-migration features each having a first end fixed to the tubular body and a second end extending radially outward from an outer surface of the tubular body. The anti-migration features may be formed of a closed loop of one or more of the interwoven wires extending from the outer surface of the tubular body. The closed loops may be formed at the first end, the second end and/or along a medial region of the tubular body. In some instances, the base of the loops may be a cross-over point of the wire(s) forming the closed loop. The wire(s) may be welded at the cross-over point.

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.
