An endoprosthesis may include an expandable tubular framework expandable from a compressed state to an expanded state and include a plurality of strut rows, wherein adjacent strut rows define interstices spacing the adjacent strut rows apart, and a plurality of connectors extending across the interstices and interconnecting adjacent strut rows, at least some of the plurality of connectors defining a flexible hinge portion. The lengths of the interstices between adjacent strut rows may vary along the length of the expandable tubular framework. The plurality of connectors extend radially outward beyond an outer diameter of the plurality of strut rows in the expanded state. The plurality of connectors are configured to engage a wall of a body lumen in the expanded state to inhibit migration of the endoprosthesis subsequent implanting the endoprosthesis in the body lumen.
