A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied without the need to use different sizes of staples.

The surgical staple cartridge of claim 1 wherein all of the first and second surgical staples have substantially the same unformed size and shape. 11. A surgical staple cartridge for use with a surgical stapling instrument that includes an anvil that includes at least one tissue stop portion thereon, the surgical staple cartridge comprising: a cartridge body configured to be operably seated in a cartridge supporting portion of the surgical stapling instrument to confront a staple forming surface on the anvil when the anvil is moved to a closed position, the cartridge body including an elongate slot for receiving a cutting portion of the surgical stapling instrument;a plurality of first staple drivers operably supported in said cartridge body and configured to eject surgical staples into forming contact with the staple forming surface on the anvil in at least two linear rows located on at least one lateral side of the elongate slot such that at least a portion of a proximal-most surgical staple in each said linear row is located proximal to a distal end of at least one of the tissue stop portions on the anvil when the surgical staples are ejected into forming contact with the staple forming surface on the anvil; anda plurality of second staple drivers movably supported in said cartridge body and configured to eject other surgical staples in another linear row located on said at least one lateral side of the elongate slot into forming contact with the staple forming surface on the anvil such that a proximal-most other surgical staple in said another linear row is distal to the distal end of the at least one tissue stop portion and wherein the other surgical staples ejected by the second staple drivers have a formed staple height that differs from a formed staple height of the surgical staples in at least one said linear row of surgical staples ejected by said first staple drivers. 12. The surgical staple cartridge of claim 11 wherein each said first staple driver operably supports two said surgical staples. 13. The surgical staple cartridge of claim 11 wherein the formed heights of the surgical staples in one said linear row of said at least two linear rows differs from other formed heights of the surgical staples in the other said linear row of said at least two linear rows of staples on a same lateral side of the elongate slot. 14. The surgical staple cartridge of claim 13 wherein a formed height of each of the surgical staples in each said linear row differs from the formed heights of the staples in the other said linear rows on a same side of the elongate slot. 15. The surgical staple cartridge of claim 11 wherein the at least two linear rows of surgical staples configured to be ejected by said plurality of first staple drivers on one side of said elongate slot are closer to the elongate slot than the other said linear row of other surgical staples configured to be ejected by said plurality of second staple drivers on a same side of the elongate slot. 16. The surgical staple cartridge of claim 11 wherein all of the surgical staples and other surgical staples have substantially the same unformed size and shape. 17.
