1. A surgical apparatus comprising:

  • a housing including an actuating mechanism;

    an elongate tubular member extending distally from the housing;

    a staple fastening assembly located at a distal end of the elongate tubular member, the staple fastening assembly including a first jaw and a second jaw, the first jaw including a plurality of fasteners and a driving assembly, the second jaw including an anvil, the first jaw including at least one movable member disposed therein, the at least one movable member being selectively actuated for interacting with a portion of a surgical fastener;

    a jaw driving assembly, the jaw driving assembly operatively coupled to the actuating mechanism such that actuation of the actuating mechanism moves one of the first and second jaws towards the other of the first and second jaws; and

    at least one sled assembly, the sled assembly including first and second sleds, the first sled including a longitudinal passage therethrough for slidably receiving the second sled, wherein longitudinal translation of the first sled through the plurality of fasteners sequentially ejects the surgical fasteners and longitudinal translation of the second sled through the plurality of fasteners moves the at least one movable member towards the tissue contacting surface of the first jaw, the at least one movable member moving in a direction that is transverse to a longitudinal axis of the first jaw, and longitudinal translation of the first sled precedes longitudinal translation of the second sled defining a delay.
