Abstract

A fastener cartridge can comprise a cartridge body including a plurality of cavities arranged in longitudinal rows. Some of the cavities can have fasteners removably stored therein. Other cavities can have deployable tissue engaging members stored therein which are movable from an undeployed position to a deployed position to engage tissue. In some instances, the fastener cartridge can include at least one longitudinal row of cavities which each include a deployable tissue engaging member. Such rows of cavities can comprise the outer-most rows of cavities in the fastener cartridge.

Claims

1. A fastener cartridge for use with a fastening instrument to fasten tissue, said fastener cartridge comprising:

a cartridge body including a deck and a plurality of cavities;

fasteners removably stored in said cavities, wherein said fasteners are deployable from said cavities during a firing stroke of the fastening instrument; and

a deployable tissue engaging member movably positioned in one of said cavities, wherein said tissue engaging member is movable between an undeployed position and a deployed position to engage the tissue during the firing stroke of the fastening instrument.

2. The fastener cartridge of claim 1, wherein said cartridge body comprises a longitudinal slot configured to receive a cutting element, wherein said fastener cavities are arranged in an inner longitudinal row of cavities and an outer longitudinal row of cavities, wherein said inner longitudinal row of cavities is adjacent said longitudinal slot, and wherein said deployable tissue engaging member is positioned in a cavity in said outer longitudinal row of cavities.

3. The fastener cartridge of claim 2, wherein said deployable tissue engaging member is part of a plurality of tissue engaging members, wherein each said tissue engaging member is positioned in a said cavity in said outer longitudinal row of cavities, and wherein each said tissue engaging member is movable between an undeployed position and a deployed position to engage the tissue during the firing stroke of the fastening instrument.

4. The fastener cartridge of claim 3, wherein a said deployable tissue engaging member is positioned in every cavity in said outer longitudinal row of cavities.

5. The fastener cartridge of claim 1, further comprising a sled configured to eject said fasteners from said cartridge body during the firing stroke of the fastening instrument, wherein said sled is also configured to deploy said tissue engaging member during the firing stoke of the fastening instrument.

6. The fastener cartridge of claim 5, wherein said sled comprises a first ramp configured to lift said fasteners and a second ramp configured to lift said tissue engaging member.

7. The fastener cartridge of claim 6, further comprising fastener drivers, wherein each said fastener driver is movable between an unfired position and a fired position to eject said fasteners from said fastener cavities, and wherein said first ramp is configured to slide under said fastener drivers to lift said fastener drivers toward said deck.

8. A fastener cartridge for use with a fastening instrument to fasten tissue, said fastener cartridge comprising:

a cartridge body, including;

a deck;

a plurality of fastener cavities; and

a member cavity;

fasteners removably stored in said fastener cavities, wherein said fasteners are deployable from said fastener cavities during a firing stroke of the fastening instrument, and wherein said fasteners are not stored in said member cavity; and

a deployable tissue flow control member movably positioned in said member cavity, wherein said tissue flow control member is movable between an undeployed position and a deployed position to engage the tissue during the firing stroke of the fastening instrument.

9. The fastener cartridge of claim 8, wherein said cartridge body comprises a longitudinal slot configured to receive a cutting element, wherein said fastener cavities are arranged in an inner longitudinal row of cavities and an outer longitudinal row of cavities, wherein said inner longitudinal row of cavities is adjacent said longitudinal slot, and wherein said member cavity is in said outer longitudinal row of cavities.

10. The fastener cartridge of claim 9, wherein said deployable tissue flow control member is part of a plurality of tissue flow control members, wherein said member cavity is part of a plurality of member cavities positioned in said outer longitudinal row of cavities, and wherein each said tissue flow control member is movable between an undeployed position and a deployed position to engage the tissue during the firing stroke of the fastening instrument.

11. The fastener cartridge of claim 8, further comprising a sled configured to eject said fasteners from said cartridge body during the firing stroke of the fastening instrument, wherein said sled is also configured to deploy said tissue flow control member during the firing stoke of the fastening instrument.

12. The fastener cartridge of claim 11, wherein said sled comprises a first ramp configured to lift said fasteners and a second ramp configured to lift said tissue flow control member.

13. The fastener cartridge of claim 12, further comprising fastener drivers, wherein each said fastener driver is movable between an unfired position and a fired position to eject said fasteners from said fastener cavities, and wherein said first ramp is configured to slide under said fastener drivers to lift said fastener drivers toward said deck.

14. A fastener cartridge for use with a fastening instrument to fasten tissue, said fastener cartridge comprising:

a cartridge body, including;

a deck;

a longitudinal slot defined in said deck configured to receive a cutting element therein;

an inner longitudinal row of fastener cavities adjacent said longitudinal slot;

an intermediate longitudinal row of fastener cavities adjacent said inner longitudinal row of fastener cavities;

an outer longitudinal row of member cavities adjacent said intermediate longitudinal row of fastener cavities;

fasteners removably stored in said fastener cavities, wherein said fasteners are deployable from said fastener cavities during a firing stroke of the fastening instrument, and

deployable tissue engaging members movably positioned in said member cavities, wherein said tissue engaging members are movable between an undeployed position and a deployed position to engage the tissue during the firing stroke of the fastening instrument.
