Tissue thickness compensator comprising a reservoir
First Claim
1. A staple cartridge assembly, comprising:
- a cartridge body comprising a plurality of staple cavities;
a plurality of staples, wherein said staples are at least partially positioned in said staple cavities, and wherein each said staple is movable between an unfired position and a fired position;
a compressible tissue thickness compensator, wherein said staples are configured to at least partially capture said tissue thickness compensator when said staples are moved between their unfired positions and their fired positions; and
a plurality of medicament capsules positioned within said tissue thickness compensator, wherein each said medicament capsule comprises a shell defining an enclosed void, wherein said enclosed void contains a medicament therein, wherein each said medicament capsule is positioned over a said staple cavity, and wherein said staple cavities and said staples are configured and arranged such that said medicament capsules are crushed within said staples when said staples are moved between their unfired positions and their fired positions.

Abstract
In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.
