Abstract: An endoprosthesis, such as a stent, having anti-migration features. The endoprosthesis includes an expandable tubular framework including a plurality of strut rows and a plurality of connectors extending across interstices between adjacent strut rows and interconnecting adjacent strut rows. The strut rows have an outer diameter in an expanded state and the connectors extend radially outward beyond the outer diameter of the strut rows in the expanded state. The connectors are configured to engage a wall of a body lumen in the expanded state to inhibit migration of the endoprosthesis in the body lumen. The endoprosthesis may include a polymeric cover covering the strut rows and spanning the interstices between adjacent strut rows, while a space between the connectors and the strut rows to which the connectors are interconnected with is devoid of the polymeric cover to permit tissue ingrowth around the connectors.

Abstract: A stent has a first end region, a middle region, and a second end region, each region including a plurality of strut columns. The stent includes at least one barb. Each barb in an expanded state is at an angle relative to the outer surface of the stent.
