Beschreibung
Zusammenfassung:	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.
