A fastener cartridge for use with a surgical instrument. The cartridge may include a cartridge body that has a series of staple pockets therein. A driver is movably supported in each staple pocket and is configured to operably support at least one surgical staple thereon. In one arrangement, at least some of the drivers may be formed with one or more laterally extending features that are configured to be received in correspondingly-shaped grooves in the cartridge body to provide lateral support to the driver as it is operably moved within the staple pocket. In other arrangements, at least one inwardly-extending features is formed in the inner wall surface of the pocket and is configured to be movably supported within correspondingly-shaped groove in the driver.
1. A fastener cartridge for use with a surgical instrument, wherein the fastener cartridge comprises: a cartridge body comprising a deck and at least one staple pocket, wherein each said staple pocket comprises an opening in said deck and defines an inner pocket surface; anda driver movably position
1. A fastener cartridge for use with a surgical instrument, wherein the fastener cartridge comprises: a cartridge body comprising a deck and at least one staple pocket, wherein each said staple pocket comprises an opening in said deck and defines an inner pocket surface; anda driver movably positioned in at least one said staple pocket and supporting a surgical fastener thereon, said driver comprising: a driver body including an outer surface portion that confronts said inner pocket surface of said staple pocket in which said driver body is movably positioned; andat least one feature extending laterally from said outer surface portion and being movably positioned against said inner pocket surface;wherein said driver body further comprises a first driver portion comprising: a first proximal driver portion including a first proximal outer surface portion; anda first distal driver portion including a first distal outer surface portion and wherein said at least one laterally extending feature comprises a first proximal support column extending laterally from said first proximal outer surface portion and a first distal support column extending laterally from said first distal outer surface portion. 2. The fastener cartridge of claim 1, wherein said first proximal driver portion includes another first proximal outer surface portion and wherein said first distal driver portion includes another first distal outer surface portion and wherein said fastener cartridge further comprises another first proximal support column extending laterally from said another first proximal outer surface portion and another first distal support column extending laterally from said another first distal outer surface portion. 3. The fastener cartridge of claim 2, wherein said another first proximal support column is movably received within a correspondingly-shaped first proximal groove in said inner pocket surface. 4. The fastener cartridge of claim 1, wherein said driver body further comprises a second driver portion coupled to said first driver portion and wherein said second driver portion comprises: a second proximal driver portion; anda second distal driver portion and wherein said at least one laterally extending feature further comprises at least one second support column extending laterally from each of said second proximal and second distal driver portions. 5. The fastener cartridge of claim 4, wherein at least two of said second support columns are formed on said second distal driver portion and at least two other of said second support columns are formed on said second proximal driver portion. 6. The fastener cartridge of claim 5, wherein each said second support column is movably received within a correspondingly-shaped second groove in said inner pocket surface. 7. The fastener cartridge of claim 4, wherein each said second support column is movably received within a correspondingly-shaped second groove in said inner pocket surface. 8. The fastener cartridge of claim 1, wherein each said first proximal support column is movably received within a correspondingly-shaped first groove in said inner pocket surface. 9. The fastener cartridge of claim 1, wherein said first proximal driver portion comprises: a first proximal body portion including first proximal lateral sides, said first proximal body portion including a first proximal body width; anda first proximal end portion including a first proximal end width that is less than said first proximal body width and wherein said first distal driver portion comprises:a first distal body portion including first distal lateral sides, said first distal body portion including a first distal body width; anda first distal end portion including a first distal end width that is less than said first distal body width. 10. A fastener cartridge for use with a surgical instrument, wherein the fastener cartridge comprises: a cartridge body comprising a deck and at least one staple pocket, wherein each said staple pocket comprises an opening in said deck and defines an inner pocket surface; anda driver movably positioned in at least one said staple pocket and supporting a surgical fastener thereon, said driver comprising: a driver body including an outer surface portion that confronts said inner pocket surface of said staple pocket in which said driver body is movably positioned; andat least one feature extending laterally from said outer surface portion and being movably positioned against said inner pocket surface, wherein each of said at least one laterally extending features is movably received within a correspondingly-shaped groove in said inner pocket surface. 11. A fastener cartridge for use with a surgical instrument, wherein the fastener cartridge comprises: a cartridge body comprising a deck and at least one staple pocket, wherein said staple pocket comprises an opening in said deck and defines an inner pocket surface;a driver movably positioned in said staple pocket and supporting a surgical fastener thereon; andat least one feature extending inwardly from said inner pocket surface to be movably received within a correspondingly-shaped groove in said driver. 12. The fastener cartridge of claim 11, wherein said inner pocket surface comprises a pair of opposed inner pocket surface portions and wherein each said inner pocket surface portion includes at least one of said inwardly extending features that is movably received within said correspondingly-shaped groove in said driver. 13. The fastener cartridge of claim 12, wherein each said inner pocket surface includes two of said inwardly extending features configured to be received within said correspondingly-shaped grooves in said driver. 14. A fastener cartridge for use with a surgical instrument, wherein the fastener cartridge comprises: a cartridge body comprising a deck with a plurality of staple pockets formed therein; anda plurality of drivers wherein each said staple pocket has a corresponding one of said drivers movably supported therein, each said driver supporting at least one surgical fastener thereon, at least some of said drivers including at least one laterally extending feature that is configured to be movably received within a correspondingly-shaped groove formed in a wall of said staple pocket in which is said driver is movably supported. 15. The fastener cartridge of claim 14, wherein at least some, but not all, of said drivers include at least one laterally extending feature. 16. The fastener cartridge of claim 15, wherein said cartridge body further comprises an elongate slot and wherein said plurality of staple pockets comprises: first, second and third rows of first staple pockets on a first side of said elongate slot, wherein said third row of said first staple pockets is further away from said elongate slot than said first and second rows; andfourth, fifth and sixth rows of second staple pockets on a second side of said elongate slot, wherein said sixth row of said second staple pockets is further away from said elongate slot than said fourth and fifth rows and wherein only those said drivers in said third row of said first staple pockets and said drivers in said sixth row of said second staple pockets include said at least one laterally extending feature. 17.
