TISSUE THICKNESS COMPENSATOR COMPRISING A RESERVOIR

摘要

In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsothable 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.

主权项

1. A staple cartridge assembly, comprising:
a cartridge body, comprising:
a first row of staple cavities; anda second row of staple cavities; staples, wherein each said staple is at least partially positionable within a said staple cavity, 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 medicament capsule positioned intermediate said first row of staple cavities and said second row of staple cavities, wherein said staple cavities and said staples are configured and arranged such that said staples do not puncture said medicament capsule when said staples are moved between their unfired positions and their fired positions, and wherein said medicament capsule comprises a shell at least partially comprised of a bioabsorbable material.
