A staple cartridge assembly is disclosed comprising one or more wire staples and one or more staples formed from a sheet of material.
Claims20
A staple cartridge assembly, comprising:
- a cartridge body, comprising:
- a deck comprising a proximal end, a distal end, and a longitudinal cartridge axis;
- a longitudinal slot defined in said deck, wherein said longitudinal slot is configured to receive a firing member;
- a first longitudinal row of staple cavities;
- and
- a second longitudinal row of staple cavities;
- a sled movable toward said distal end by the firing member during a firing stroke;
- a plurality of first staples removably stored in said first longitudinal row of staple cavities, wherein each said first staple comprises a first geometry;
- a plurality of staple drivers configured to support said first staples, wherein said sled is configured to engage said staple drivers to eject said first staples from said first longitudinal row of staple cavities during the firing stroke;
- and
- a plurality of second staples removably stored in said second longitudinal row of staple cavities, wherein each said second staple comprises an integrally-formed driver and comprises a second geometry and bowed shape when at least viewed from the top of said deck, wherein each said second staple comprises a second geometry, wherein said second geometry is different than said first geometry, and wherein said sled is configured to directly engage said integrally-formed drivers of said second staples and eject said second staples from said second longitudinal row of staple cavities during the firing stroke.

A staple cartridge assembly, comprising:
- a cutting member;
- a cartridge body, comprising:
- a deck comprising a proximal end, a distal end, and a longitudinal axis;
- a longitudinal slot defined in said deck, wherein said longitudinal slot is configured to receive said cutting member;
- a first longitudinal row of staple cavities;
- and
- a second longitudinal row of staple cavities;
- a sled movable toward said distal end by said cutting member during a firing stroke;
- a plurality of first staples removably stored in said first longitudinal row of staple cavities, wherein each said first staple comprises a first form;
- a plurality of staple drivers configured to support said first staples, wherein said sled is configured to engage said staple drivers to eject said first staples from said first longitudinal row of staple cavities during said firing stroke;
- and
- a plurality of second staples removably stored in said second longitudinal row of staple cavities, wherein said second staples comprise a bowed shape when at least viewed from the top of said deck and a second form different than the first form, and wherein said sled is configured to directly engage said second staples and eject said second staples from said second longitudinal row of staple cavities during said firing stroke.
