Surgical stapling apparatus are disclosed including an anvil having a working surface with a shaped topography; and a staple cartridge, in juxtaposition with the anvil. The staple cartridge includes a working surface with shaped topography which is complementary to the shaped topography of the working surface of the shaped anvil. When the anvil and the staple cartridge are approximated with or toward one another, at least a portion of the working surface of the anvil cooperates with at least a portion of the working surface of the staple cartridge to enhance alignment of the staple cartridge and the anvil in at least one of a transverse and longitudinal direction.
What is claimed is: 1. A surgical stapling apparatus, comprising: an anvil having a working surface including a plurality of staple forming depressions formed therein, the working surface of the anvil including a pair of inclined wall portions extending along a length thereof and having a non-plana
What is claimed is: 1. A surgical stapling apparatus, comprising: an anvil having a working surface including a plurality of staple forming depressions formed therein, the working surface of the anvil including a pair of inclined wall portions extending along a length thereof and having a non-planar cross-sectional shape; and a staple cartridge having a working surface in juxtaposition to the working surface of the anvil and including a plurality of staple retention slots formed therein, the working surface of the staple cartridge including a pair of inclined wall portions extending longitudinally along a length thereof and having a shape which complements the shape of the working surface of the anvil, such that as the anvil and staple cartridge are approximated relative to one another with tissue therebetween, the working surface of the anvil cooperates with the working surface of the staple cartridge to help align the plurality of staple forming depressions with the plurality of staple retention slots. 2. A surgical stapling apparatus, comprising: an anvil having a working surface with a shaped topography, the working surface including a pair of inclined wall portions extending along a length thereof and; and a staple cartridge having a working surface in juxtaposition with the anvil, the working surface of the staple cartridge including a pair of inclined wall portions extending longitudinally along a length thereof and having a shaped topography which is complementary to the shaped topography of the working surface of the shaped anvil, such that as the anvil and the staple cartridge are approximated with one another with tissue therebetween, cooperation of at least a portion of the working surface of the anvil with at least a portion of the working surface of the staple cartridge enhances alignment of the staple cartridge and the anvil in at least one of a transverse and longitudinal direction. 3. A surgical stapling apparatus, comprising: an anvil having a working surface including a plurality of staple forming depressions formed therein, the working surface of the anvil including a pair of inclined wall portions extending along a length thereof and having a non-planar cross-sectional shape; and a staple cartridge having a working surface in juxtaposition to the working surface of the anvil and including a plurality of staple retention slots formed therein, the working surface of the staple cartridge including a pair of inclined wall portions extending longitudinally along a length thereof and having a shape which complements the shape of the working surface of the anvil, such that when the anvil and staple cartridge are approximated relative to one another the working surface of the anvil cooperates with the working surface of the staple cartridge to help align the plurality of staple forming depressions with the plurality of staple retention slots. 4. The surgical stapling apparatus according to claim 3, wherein each inclined wall portion of the staple cartridge has an inner longitudinal edge and an outer longitudinal edge, wherein the inner longitudinal edges of the pair of inclined wall portions are recessed with respect to a plane defined by the outer longitudinal edges. 5. The surgical stapling apparatus according to claim 4, wherein each inclined wall portion of the staple cartridge has an outer longitudinal edge and an inner longitudinal edge, and the inner longitudinal edges are parallel and spaced apart from one another, recessed with respect to a plane defined by the outer longitudinal edges, and define a knife track. 6. The surgical stapling apparatus according to claim 3, wherein the staple cartridge includes first and second side walls, parallel to and spaced apart from one another, and wherein a first inclined wall portion of the staple cartridge extends from the first side wall of the staple cartridge at an angle which is less than 90째 relative to the first side wall and a second inclined wall portion of the staple cartridge extends from the second side wall of the staple cartridge at an angle which is less than 90째 relative to the second side wall. 7. The surgical stapling apparatus according to claim 3, wherein each inclined wall portion of the anvil has an inner longitudinal edge and an outer longitudinal edge, wherein the inner longitudinal edge of the pair of inclined wall portions is elevated with respect to a plane defined by the outer longitudinal edges. 8. The surgical stapling apparatus according to claim 7, wherein each inclined wall portion of the staple cartridge has an outer longitudinal edge and an inner longitudinal edge, and the inner longitudinal edges are parallel and spaced apart from each other, recessed with respect to a plane defined by the outer longitudinal edges, and define a knife track. 9. The surgical stapling apparatus according to claim 3, wherein the anvil includes first and second side walls, parallel to and spread apart from one another, and wherein a first inclined wall portion of the anvil extends from the first side wall of the anvil at an angle which is greater than 90째 and less than 180째 relative to the first side wall and a second inclined wall portion of the staple cartridge extends from the second side wall of the anvil at an angle which is greater than 90째 and less than 180째 relative to the second side wall. 10. The surgical stapling apparatus according to claim 3, wherein at least one of the staple cartridge and the anvil includes a longitudinally running channel extending along the length thereof.
