Abstract

A staple cartridge for use with a surgical stapler can comprise a cartridge deck and a plurality of staples at least partially positioned within the cartridge deck. In various embodiments, the staples can comprise legs which extend upwardly from the deck wherein the deck can further include supports, or guides, which are configured to hold the staple legs in a particular alignment. In at least one such embodiment, the staple legs can extend upwardly from the supports into a tissue thickness compensator.

Claims

1-20. -20. (canceled)

21. A staple cartridge assembly for use with a surgical stapling instrument, said staple cartridge assembly comprising:

a plurality of staples comprising at least a first row of staples and a second row of staples, and wherein each said staple comprises a base and at least two legs extending from said base;

an implantable layer; and

a movable cartridge portion, comprising;

a deck surface;

a plurality of apertures defined in said deck surface, wherein said first row of staples are removably stored within said apertures, and wherein relative movement is afforded between said movable cartridge portion and said staples upon an application of a firing actuation to said staple cartridge assembly; and

a plurality of elevated staple guide portions extending higher than said deck surface.

22. A fastener cartridge assembly for use with a surgical fastening instrument, said fastener cartridge assembly comprising:

a plurality of fasteners comprising a first row of fasteners and a second row of fasteners, and wherein each said fastener comprises a base and at least two legs extending from said base;

an implantable layer; and

a movable cartridge body, comprising;

a deck surface;

a plurality of apertures defined in said deck surface, wherein said first row of fasteners are removably stored within said apertures, wherein said movable cartridge body is movable from a first position to a second position such that said movable cartridge body is movable between said first position and said second position upon an application of a firing actuation to said fastener cartridge assembly, and wherein the movement of said moveable cartridge body comprises relative movement between said fasteners and said movable cartridge body; and

a plurality of elevated fastener guide portions extending above said deck surface.

23. A staple cartridge assembly for use with a surgical stapling instrument including an anvil, said staple cartridge assembly comprising:

a staple cartridge;

a plurality of staples, wherein each said staple comprises a base and at least two legs extending from said base, and wherein each said leg comprises a staple tip;

a deck;

a tissue-supporting surface;

an implantable layer;

a plurality of apertures defined in said staple cartridge, wherein said legs of said staples at least partially extend into said apertures, and wherein said tissue-supporting surface is collapsible relative to said tips of said staples between an unfired position and a fired position when said staple legs are deformed by the anvil of the surgical stapling instrument; and

a plurality of staple guides, wherein each said staple guide is configured to slidably receive a said leg of a said staple therein.
