One exemplary surgical apparatus may include at least one carrier, staples fixed to a corresponding carrier, and a feeder belt to which at least one carrier is frangibly connected. Another exemplary surgical apparatus may include a staple holder, an anvil movably connected to the staple holder, a feeder belt, where at least part of the feeder belt extends into the staple holder, and staples fixed to and frangibly separable from the feeder belt; where the staples are organized into at least two groups spaced apart from one another; and where at least one staple is deployable to a different closed shape than at least one other staple. Another exemplary surgical apparatus may include a feeder belt, a first plurality of staples fixed directly to and frangibly separable from the feeder belt; a plurality of extension arms extending at least partially in the lateral direction away from the feeder belt; and a second plurality of staples each fixed to an extension arm at a location spaced laterally apart from the feeder belt.
