Abstract
A tissue thickness compensator comprising at least one woven lattice can be positioned in the end effector of a surgical instrument. A fastener cartridge that is positioned in the end effector can comprise at least one cavity configured to receive a fastener. The fastener can be moveable between an initial position, wherein the fastener is at least partially position in a cavity, and a fired position, wherein the fastener is configured to compress a woven lattice of the tissue thickness compensator. The woven lattice can comprise a resilient material such that compression of the woven lattice generates a restoring force. The woven lattice can also comprise an axis that can laterally traverse the fastener cartridge, diagonally traverse the fastener cartridge, or intersect a deck surface of the fastener cartridge. The woven lattice can comprise a hydrophilic substance, which can expand when the woven lattice is severed by a cutting element.
