An end effector for a surgical clip applier includes an elongate body, a clip forming system positioned within the body and arranged to receive an unformed surgical clip, and an actuation mechanism operatively coupled to the clip forming system to actuate the clip forming system and thereby bend the unformed surgical clip into a tissue-ready surgical clip. First and second jaw members are positioned at a distal end of the body and arranged to receive the tissue-ready surgical clip for crimping.
