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. An end effector, comprising:

a first jaw;

a second jaw comprising an anvil, wherein at least one of said first jaw and said second jaw is movable to compress tissue between said first jaw and said second jaw;

a staple cartridge assembly, comprising;

a staple cartridge;

an implantable cartridge layer assembly adhesively secured to said staple cartridge, wherein said cartridge layer assembly comprises;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material wherein said film layer of said cartridge layer assembly at least partially wraps around said at least one fibrous layer and said polyglycolic acid material of said cartridge layer assembly; and

an implantable anvil layer assembly adhesively secured to said anvil, wherein said anvil layer assembly comprises;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material.

2. The end effector of claim 1, wherein said staple cartridge comprises a plurality of staple cavities, and wherein a plurality of staples are positioned in said staple cavities when said staples are in an unfired position.

3. The end effector of claim 2, wherein each of said staples comprises one or more deformable legs, and wherein said film layer comprises a plurality of holes configured to receive the deformable legs of said staples.

4. An end effector, comprising:

a first jaw;

a second jaw comprising an anvil, wherein at least one of said first jaw and said second jaw is movable to compress tissue between said first jaw and said second jaw;

a staple cartridge assembly, comprising;

a staple cartridge;

wherein said staple cartridge comprises a plurality of staples;

an implantable cartridge layer assembly adhesively secured to said staple cartridge, wherein said cartridge layer assembly comprises;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material, wherein said staples are at least partially positioned within said cartridge layer assembly when said staples are in an unfired position; and

an implantable anvil layer assembly adhesively secured to said anvil, wherein said anvil layer assembly comprises;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material.

5. The end effector of claim 4, wherein each of said staples comprises one or more deformable legs, and wherein said film layer comprises a plurality of holes configured to receive the deformable legs of said staples.

6. An end effector, comprising:

a first jaw comprising a staple cartridge channel;

a second jaw comprising an anvil, wherein at least one of said first jaw and said second jaw is movable to compress tissue between said first jaw and said second jaw;

a staple cartridge positioned in said staple cartridge channel, wherein said staple cartridge comprises;

an implantable cartridge layer assembly, comprising;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material, wherein said film layer of said cartridge layer assembly at least partially wraps around said at least one fibrous layer and said polyglycolic acid material of said cartridge layer assembly; and

an implantable anvil layer assembly detachably secured to said anvil, comprising;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material.

7. An end effector, comprising:

a first jaw comprising a staple cartridge channel;

a second jaw comprising an anvil, wherein at least one of said first jaw and said second jaw is movable to compress tissue between said first jaw and said second jaw;

a staple cartridge positioned in said staple cartridge channel, wherein said staple cartridge comprises;

an implantable cartridge layer assembly, comprising;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material, wherein said staple cartridge further comprises a plurality of staples, and wherein said staples are at least partially positioned within said cartridge layer assembly when said staples are in an unfired position; and

an implantable anvil layer assembly detachably secured to said anvil, comprising;

at least one fibrous layer;

a film layer; and

a polyglycolic acid material.

8. The end effector of claim 7, wherein each of said staples comprises one or more deformable legs, and wherein said film layer comprises a plurality of holes configured to receive the deformable legs of said staples.
