In various embodiments, an end effector for use with a surgical instrument is disclosed. The end effector comprises a first jaw and a second jaw moveable relative to the first jaw, wherein one of the first jaw and the second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, and wherein at least one curved staple cavity row extends along a path. The path comprises a first curved portion comprising a first longitudinal vector component and a second curved portion comprising a second longitudinal vector component, wherein the second longitudinal vector component is opposite of the first longitudinal vector component. The end effector further comprises a firing member comprising a laterally-offset cutting edge, a first camming surface configured to engage the first jaw, and a second camming surface configured to engage the second jaw.
1. An end effector for use with a surgical instrument, the end effector comprising: a first jaw;a second jaw moveable relative to said first jaw, wherein one of said first jaw and said second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, wherein a
1. An end effector for use with a surgical instrument, the end effector comprising: a first jaw;a second jaw moveable relative to said first jaw, wherein one of said first jaw and said second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, wherein at least one curved staple cavity row extends along a path, and wherein said path comprises: a first curved portion comprising a first longitudinal vector component; anda second curved portion comprising a second longitudinal vector component, wherein said second longitudinal vector component is opposite of said first longitudinal vector component; anda firing member comprising: a laterally-offset cutting edge;a first camming surface configured to engage said first jaw; anda second camming surface configured to engage said second jaw. 2. The end effector of claim 1, wherein said first longitudinal vector component comprises a distal vector component, and wherein said second longitudinal vector component comprises a proximal vector component. 3. The end effector of claim 1, wherein said first curved portion is distal relative to said second curved portion. 4. The end effector of claim 1, wherein said first curved portion and said second curved portion comprise a third vector component, and wherein said third vector component is perpendicular to said first and second longitudinal vector components. 5. The end effector of claim 1, further comprising a plurality of staples removably positioned in said staple cavities. 6. The end effector of claim 5, further comprising: a cutting element structured to travel along a curved slot between two curved staple cavity rows of said plurality of curved staple cavity rows; anda sled structured to move said cutting element along the curved slot, wherein said sled is structured to progressively deploy said staples from said staple cavities. 7. The end effector of claim 6, wherein said cutting element comprises: a proximal end;a central axis extending distally from said proximal end; anda distal end laterally offset from said central axis. 8. The end effector of claim 7, wherein said cutting element is asymmetrical relative to said central axis. 9. The end effector of claim 6, wherein said cutting element comprises: a cutting element body comprising a proximal end and a distal end; andsaid laterally-offset cutting edge extending from said distal end, wherein said laterally-offset cutting edge is non-centered relative to said proximal end. 10. The end effector of claim 6, wherein the curved slot curves in a first direction, and wherein said cutting element is pre-biased toward the first direction. 11. The end effector of claim 10, wherein said cutting element comprises means for leading said cutting element in a predisposed direction, and wherein the predisposed direction corresponds to the first direction. 12. An end effector for use with a surgical instrument, the end effector comprising: a first jaw;a second jaw moveable relative to said first jaw, wherein one of said first jaw and said second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, wherein at least one curved staple cavity row extends along an arc defining a subtended angle, and wherein the subtended angle is greater than 90 degrees; anda firing assembly, comprising: a first camming surface configured to engage said first jaw;a second camming surface configured to engage said second jaw; anda cutting element structured to travel along a curved path between two curved staple cavity rows of said plurality of curved staple cavity rows, wherein said cutting element comprises a laterally-offset cutting edge. 13. The end effector of claim 12, wherein the curved path comprises: a proximal curved portion extending distally; anda distal curved portion extending proximally. 14. The end effector of claim 12, further comprising a plurality of progressively-deployable staples positioned in said staple cavities. 15. The end effector of claim 12, wherein said cutting element comprises: a cutting element body comprising a proximal end and a distal end; andsaid laterally-offset cutting edge extending from said distal end, wherein said laterally-offset cutting edge is non-centered relative to said proximal end. 16. The end effector of claim 12, wherein the curved path curves in a first direction, and wherein said cutting element is pre-biased toward the first direction. 17. An end effector for use with a surgical instrument, the end effector comprising: a first jaw;a second jaw moveable relative to said first jaw, wherein one of said first jaw and said second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows;a curved slot positioned between two curved staple cavity rows of said plurality of curved staple cavity rows, wherein said curved slot extends along a curve defining a subtended angle, and wherein the subtended angle is greater than 90 degrees; anda firing assembly comprising: a first camming surface configured to engage said first jaw;a second camming surface configured to engage said second jaw; andmeans for cutting, wherein said means for cutting is structured to travel along said curved slot, and wherein said means for cutting comprises a laterally-offset cutting edge. 18. The end effector of claim 17, further comprising a plurality of staples removably positioned in said staple cavities. 19. The end effector of claim 18, further comprising means for progressively deploying said staples from said staple cavities. 20. The end effector of claim 17, wherein said curved slot curves in a first direction, and wherein said means for cutting is pre-biased toward the first direction.
