12. The staple cartridge of claim 7 , wherein said inner staple is positioned proximally with respect to said intermediate staple, and wherein said intermediate staple is positioned proximally with respect to said outer staple.

13. A staple cartridge, comprising:

a cartridge body, comprising:

a proximal end;

a distal end;

a deck;

a longitudinal slot defined in said deck, wherein said longitudinal slot extends from said proximal end toward said distal end;

staple cavities defined in said deck, wherein said staple cavities comprise:

an inner row of staple cavities extending alongside said longitudinal slot;

an intermediate row of staple cavities extending alongside said inner staple cavity row; and

an outer row of staple cavities extending alongside said intermediate staple cavity row;

staples removably stored in said staple cavities, wherein said staples comprise an unformed height;

a proximal double staple driver configured to eject two staples from said staple cavities;

intermediate tri-staple drivers, wherein each said intermediate tri-staple driver is configured to eject an inner staple from said inner row, an intermediate staple from said intermediate row, and an outer staple from said outer row, and wherein said intermediate tri-staple drivers are positioned distally with respect to at least a portion of said proximal double staple driver; and

distal single staple drivers configured to each eject a staple from said staple cavities, wherein said distal single staple drivers move independently of said intermediate tri-staple drivers, and wherein said distal single staple drivers are positioned distally with respect to at least a portion of said intermediate tri-staple drivers.

14. The staple cartridge of claim 13 , wherein said staples comprise the same unformed height.

15. The staple cartridge of claim 13 , wherein said staples comprise different formed heights.

16. The staple cartridge of claim 13 , wherein said intermediate tri-staple drivers are arranged in a repeating pattern in between said proximal double staple driver and said distal single staple drivers.
