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 occlusion device having a support structure and an expandable occlusion element associated with the support structure. The expandable occlusion element is formed of a self-expanding material, such as a hydrogel. A retainer may be provided to hold the expandable occlusion element with respect to the support structure of the occlusion device, within or outside the support structure, and positioned such that expansion of the expandable occlusion element occludes a lumen through the support structure and the occlusion device. Expansion of the expandable occlusion element may be reversible, or the expandable occlusion element may be releasable from the support structure.
