The present embodiments provide a stent comprising a plurality of interconnected strut segments that enable expansion of the stent from a delivery state to a deployed state. A first strut segment and a second strut segment, of the plurality of strut segments, each comprise frontal surfaces facing radially inward in the deployed state and rear surfaces facing radially outward in the deployed state. The frontal surface of the first strut segment is at least partially stacked behind the rear surface of the second strut segment in the delivery state. A first barb coupled to at least a portion of the first strut segment. A sharpened tip of the first barb is aligned at least partially circumferentially behind at least one strut segment in the delivery state such that the sharpened tip is not radially exposed.
