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.

Tissue thickness compensator comprising layers

In various embodiments, a tissue thickness compensator can comprise one or more capsules and/or pockets comprising at least one medicament therein. In at least one embodiment, staples can be fired through the tissue thickness compensator to rupture the capsules. In certain embodiments, a firing member, or knife, can be advanced through the tissue thickness compensator to rupture the capsules.

Tissue thickness compensator

A stapling assembly comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises a body portion comprising a porous material and a plurality of cavities defined in the body portion, wherein the cavities are aligned with forming surfaces of an anvil such that fasteners of a fastener cartridge are configured to at least one of the cavities when the fasteners are ejected from the fastener cartridge or capture the cavities and compress the cavities within the tissue thickness compensator when the fasteners are ejected from the fastener cartridge and formed by forming surfaces of the anvil. The stapling assembly further comprises at least one medicament positioned within each cavity prior to firing the stapler, wherein the medicament is different than the porous material.

Tissue thickness compensator comprising at least one medicament

A retainer for assembling tissue thickness compensators to a surgical stapler can comprise a grip, a first surface for supporting a first tissue thickness compensator, a second surface for supporting a second tissue thickness compensator, and clips for aligning and attaching the retainer to the surgical stapler. The clips may align and attach the retainer to a staple cartridge of the surgical instrument. The clips may align the retainer with an anvil of the surgical instrument. An insertion tool may be used in combination with the retainer to insert the retainer into the surgical stapler and to push the tissue thickness compensators against the anvil and/or the staple cartridge of the surgical instrument.

Retainer assembly including a tissue thickness compensator

In various embodiments, a tissue thickness compensator can comprise a film body formed from a continuous extruded shape and, in addition, a fibrous medicament core.
