Abstract

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.

Claims

1. A stapling assembly for use with a stapler, said stapling assembly comprising:

an anvil comprising a plurality of forming surfaces;

a fastener cartridge comprising a plurality of fasteners stored therein, wherein said fasteners are formable against said forming surfaces;

a tissue thickness compensator attached to said anvil, wherein said tissue thickness compensator comprises;

a body portion comprising a porous material; and

a plurality of cavities defined in said body portion, wherein said cavities are aligned with said forming surfaces such that said fasteners are configured to at least one of puncture said cavities when said fasteners are ejected from said fastener cartridge or capture said cavities and compress said cavities within said tissue thickness compensator when said fasteners are ejected from said fastener cartridge and formed by said forming surfaces; and

at least one medicament positioned within each said cavity prior to firing the stapler, wherein said medicament is different than said porous material,

wherein said plurality of cavities comprises a plurality of bubbles,

wherein said tissue thickness compensator comprises a first layer and a second layer, and wherein said bubbles are defined between said first layer and said second layer.

2. A stapling assembly for use with a stapler comprising an anvil, wherein the anvil includes a forming surface configured to deform a staple, said stapling assembly comprising:

a releasing material configured to be at least partially captured by a plurality of staples, said releasing material comprising;

a body portion comprising a porous material; and

a cavity defined in said body portion, wherein said cavity is configured to be aligned with the forming surface of the anvil such that the staple is configured to puncture said cavity when the staple is ejected from a staple cartridge or capture said cavity and compress said cavity within said releasing material when the staple is ejected from the staple cartridge and formed by the forming surface;

a medicament positioned within said cavity, wherein said medicament is different than said porous material; and

an attachment portion configured to be attached to the anvil to attach said releasing material to the anvil,

wherein said cavity is defined by a sidewall, wherein said releasing material comprises a first layer and a second layer, and wherein portions of said first layer are connected to said second layer to define said sidewall.
