Abstract
An apparatus for application of surgical clips to body tissue has a handle portion; a body extending distally from the handle portion; a plurality of surgical clips disposed within the body; and a jaw assembly mounted adjacent a distal end portion of the body. The jaw assembly includes first and second jaw portions movable between a spaced-apart and an approximated position. The apparatus also has a wedge plate longitudinally movable between the first and the second jaw portions, a clip pusher configured to individually distally advance a surgical clip to the jaw assembly while the jaw portions are in the spaced apart position; an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion; and a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position.

2. A method of applying surgical fasteners to tissue during a surgical procedure, the method comprising:
-
positioning first and second jaw portions of a surgical fastener applying apparatus in proximity to tissue; moving, in a distal direction, an actuation mechanism of the surgical fastener applying apparatus; engaging a driver of the surgical fastener applying apparatus with the actuation mechanism, thereby distally moving the driver and a slider that is secured to a proximal portion of the driver; and urging the driver into engagement with the first and second jaw portions to approximate the first and second jaw portions and form a surgical fastener about the tissue. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. An apparatus for applying surgical fasteners to tissue, comprising:
-
an elongate body portion; an actuation mechanism configured to move longitudinally through the body portion; a jaw assembly mounted adjacent a distal end of the body portion and including first and second jaw portions, the jaw assembly configured to move between a spaced apart position and an approximated position to form a surgical fastener positioned between the first and second jaw portions; and a camming mechanism coupled to a distal portion of the actuation mechanism and including; a slider slidably disposed within the actuation mechanism; and a driver having a proximal portion fixedly coupled to the slider and a distal portion configured to move the jaw assembly into the approximated position upon distal movement of the driver, wherein the actuation mechanism is configured to move distally relative to the camming mechanism a predetermined longitudinal distance such that the actuation mechanism engages the driver upon movement of the actuation mechanism more than the predetermined longitudinal distance. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
