Tissue thickness compensator comprising structure to produce a resilient load

A fastener cartridge for a surgical instrument, the fastener cartridge comprising:

• a cartridge body defining a longitudinal axis;
• a first plurality of strands woven into a resilient lattice, wherein said resilient lattice is substantially parallel to said longitudinal axis, and wherein said resilient lattice comprises:
• a top wall;
• a bottom wall;
• and
• a channel intermediate said top wall and said bottom wall, wherein said top wall and said bottom wall are positioned above said cartridge body;
• and
• fasteners moveable between an initial position and a fired position, wherein at least one said fastener is configured to compress a portion of said resilient lattice when said at least one fastener is moved to said fired position.

An end effector assembly for a surgical instrument, the end effector assembly comprising:

• an anvil;
• a fastener cartridge, comprising:
• at least one row of fastener cavities;
• and
• fasteners moveable between an initial position and a fired position, wherein each said fastener is positioned in a said fastener cavity when each said fastener is in said initial position;
• and
• a tube, wherein said tube comprises a resilient material, wherein said tube is substantially parallel to said at least one row of fastener cavities, and wherein said tube comprises:
• a top portion;
• a bottom portion;
• and
• a tubular passage intermediate said top portion and said bottom portion, wherein said top portion and said bottom portion are positioned between said anvil and said fastener cartridge;
• wherein at least one said fastener, when moved to said fired position, is configured to deform a portion of said tube.
