A closure device for an arteriotomy includes an elongate tube having a distal opening. The elongate tube has least two opposing longitudinal slots and a pair of opposing corners defined where each slot meets the distal opening. A staple is disposed within the tube, the staple having at least two opposing legs aligned with the at least two slots. Each slot is pinched together adjacent the distal opening such that the opposing corners of each slot converge to cover the tip of the respective staple leg to guard the staple tips against contact with the tissue track. The corners of each slot are separable to permit the respective staple leg to pass there between.
