Abstract: Example expandable stent designs are disclosed. An example expandable stent includes a tubular scaffold including an inner surface, an outer surface and a lumen extending therein. The expandable stent also includes an outer layer disposed along the outer surface of the tubular scaffold and a first preformed flap attached to the outer layer. Additionally, the preformed flap is configured to releasably engage a vessel wall when the stent is implanted therein.

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.
