Abstract
A closure device for an arteriotomy includes an elongate tube having a distal opening, a staple disposed within the tube, and a frangible cap mounted across the distal opening to guard the staple tips against contact with the tissue track. The frangible cap is pierced, fractured or torn when the staple is advanced through the distal opening. A portion of the torn frangible cap may be implanted with the staple as a pledget. The staple may be carried within the elongate tube by a stapler comprising an elongate hollow shaft and an elongate driver slidably disposed therein. A pair of opposing actuation tips is disposed at a distal end of the hollow shaft to define an open-sided staple chamber there between. An anvil is fixedly disposed within the staple chamber, which holds at least a proximal portion of the staple.
