A surgical stapling apparatus includes a staple cartridge and an anvil member. The staple cartridge includes a plurality of surgical fasteners disposed in rows of retention slots. The staple cartridge may have an annular or linear configuration of retention slots. The tissue contacting surface of the staple cartridge may be tapered or stepped. The anvil member has a tissue contacting surface that includes a number of pockets arranged for substantially aligning with the retention slots. In addition, the tissue contacting surface of the anvil member may complement the tissue contacting surface of the staple cartridge.
What is claimed is: 1. A staple cartridge for a surgical stapling apparatus, comprising: a first tissue contacting surface and a second tissue contacting surface, wherein the first tissue contacting surface and the second tissue contacting surface are not co-planar; a third surface extending genera
What is claimed is: 1. A staple cartridge for a surgical stapling apparatus, comprising: a first tissue contacting surface and a second tissue contacting surface, wherein the first tissue contacting surface and the second tissue contacting surface are not co-planar; a third surface extending generally between the first tissue contacting surface and the second tissue contacting surface, an angle being defined between the third surface and at least one of the first or second tissue contacting surfaces; a plurality of first retention slots defined in the first tissue contacting surface and a plurality of second retention slots defined in the second tissue contacting surface, each retention slot configured for housing a staple therein; a first plurality of staples having a first leg length and being disposed in the plurality of first retention slots; and a second plurality of staples having a second leg length and being disposed in the plurality of second retention slots, wherein the second leg length is different from the first leg length. 2. The cartridge of claim 1, wherein the cartridge is releasably attached to a body of the surgical apparatus. 3. The cartridge of claim 1, further including a knife channel extending longitudinally along the cartridge. 4. The cartridge of claim 3, wherein the first tissue contacting surface is adjacent the knife channel. 5. The cartridge of claim 4, wherein the first leg length is smaller than the second leg length. 6. The cartridge of claim 1, wherein the first tissue contacting surface is substantially parallel to the second tissue contacting surface. 7. A surgical stapling apparatus, comprising: a handle portion; a body portion extending distally from the handle portion and defining a longitudinal axis; and a tool assembly at a distal end of the body portion, the tool assembly including a cartridge having: a first tissue contacting surface and a second tissue contacting surface, wherein the first tissue contacting surface and the second tissue contacting surface are not co-planar; a third surface extending generally between the first tissue contacting surface and the second tissue contacting surface, an angle being defined between the third surface and at least one of the first or second tissue contacting surfaces; a plurality of first retention slots defined in the first tissue contacting surface and a plurality of second retention slots defined in the second tissue contacting surface, each retention slot configured for housing a staple therein; a first plurality of staples having a first leg length and being disposed in the plurality of first retention slots; and a second plurality of staples having a second leg length and being disposed in the plurality of second retention slots, wherein the second leg length is different from the first leg length. 8. The surgical stapling apparatus of claim 7, wherein the tool assembly includes an anvil member having a surface for contacting tissue, the surface of the anvil member defining a number of staple forming depressions. 9. The surgical stapling apparatus of claim 8, wherein the surface of the anvil member is disposed in opposition to the first tissue contacting surface and the second tissue contacting surface. 10. The surgical stapling apparatus of claim 8, wherein the surface of the anvil member and the first tissue contacting surface define a first gap, the surface of the anvil member and the second tissue contacting surface define a second gap, the first gap having a different dimension from the second gap. 11. The surgical stapling apparatus of claim 10, wherein the first gap is less than the second gap. 12. The surgical stapling apparatus of claim 11, wherein the first tissue contacting surface is adjacent a centerline of the cartridge. 13. The surgical stapling apparatus of claim 7, wherein the first leg length is smaller than the second leg length. 14. The surgical stapling apparatus of claim 7, wherein the plurality of first retention slots is a longitudinally extending row of retention slots and the plurality of second retention slots is a longitudinally extending row of retention slots.
