A surgical stapling apparatus having a housing with an actuator and an elongated member extending from the housing. An end effector is disposed on one end of the elongated member. The end effector houses a plurality of fasteners that are opera tively coupled to a plurality of pusher members. An actuation mechanism is operatively coupled to the actuator; the actuation mechanism includes a longitudinally translatable drive member and an actuation sled. The actuation sled is configured for engaging the plurality of pusher members. A pressure responsive element is also disposed in one of the jaws. The pressure responsive element communicates a signal to a controller. The signal is representative of pressure applied to the pressure responsive element. The controller is configured to activate a feedback response.
