Abstract

An applicator instrument for dispensing surgical fasteners includes a housing, a firing system disposed in the housing, an actuator coupled with the housing for actuating the firing system, an elongated shaft extending from the housing, the elongated shaft having an outer diameter, and a cap secured to the distal end of the elongated shaft, whereby the cap has a lower distal edge that extends laterally beyond the outer diameter of the elongated shaft. The lower distal edge of the cap has a length that is greater than the outer diameter of the elongated shaft. The cap has a distal end face that slopes upwardly and proximally from the lower distal edge, and the cap has a surgical fastener delivery window formed in the distal end face for dispensing surgical fasteners. The delivery window has a lower end that is spaced from the lower distal edge.
