Abstract

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

Claims

1. A staple cartridge for use with a surgical stapler, said staple cartridge comprising:

a cartridge body, comprising;

a deck; and

a plurality of staple cavities defined within said deck, wherein each said staple cavity comprises an opening in said deck;

a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, and wherein said plurality of staples comprises a first group of staples and a second group of staples; and

an implantable compressible portion comprising a first portion and a second portion, wherein said first portion is removably attached to said second portion, and wherein said first portion is configured to be captured within said first group of staples and said second portion is configured to be captured within said second group of staples.

2. The staple cartridge of claim 1, wherein said compressible portion comprises at least one perforation between said first portion and said second portion.

3. The staple cartridge of claim 1, further comprising a first fastener releasably holding said first portion to said deck and a second fastener releasably holding said second portion to said deck.

4. The staple cartridge of claim 3, further comprising a proximal end and a distal end, wherein the surgical stapler comprises a cutting member movable between said proximal end and said distal end, and wherein said cutting member is configured to incise said first fastener and said second fastener.

5. The staple cartridge of claim 3, wherein the surgical stapler comprises a cutting member configured to incise said first fastener when the staples of said first group of staples are being moved from said unfired position to said fired position and to incise said second fastener when the staples of said second group of staples are being moved from said unfired position to said fired position.

6. The staple cartridge of claim 1, wherein said plurality of staples comprises a third group of staples, wherein said compressible portion comprises a third portion removably attached to said second portion, and wherein third portion is configured to be captured within said third group of staples.

7. A staple cartridge for use with a surgical stapler, said staple cartridge comprising:

a cartridge body, comprising;

a deck; and

a cartridge body, comprising;

a deck; and

a plurality of staple cavities defined within said deck, wherein each said staple cavity comprises an opening in said deck;

a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, and wherein said plurality of staples comprises a first group of staples and a second group of staples; and
