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.
