A fastener cartridge assembly for an end effector of a surgical instrument can comprise a cartridge body, a deformable tube, and a fastener moveable between an initial position and a fired position. The deformable tube can be longitudinally positioned along a length of the cartridge body. When the fastener is moved to the fired position, the fastener can compress a portion of the deformable tube. The deformable tube can comprise a resilient material such that deformation of the deformable tube generates a restoring force. The deformable tube can comprise a lattice of strands woven together to form a tube wall. Further, the deformable tube can be bioabsorbable and can hold a therapeutic agent. The fastener cartridge assembly can comprise multiple, substantially parallel deformable tubes positioned side-by-side and/or within each other.

The fastener cartridge assembly of claim 6, further comprising a third deformable tube, wherein said third deformable tube is positioned within said second deformable tube. 8. The fastener cartridge assembly of claim 5, further comprising a third deformable tube, wherein said first deformable tube is aligned with a longitudinal axis defined by said cartridge body, wherein said second deformable tube is positioned on a first side of said first deformable tube, and wherein said third deformable tube is positioned on a second side of said first deformable tube. 9. The fastener cartridge assembly of claim 5, wherein said first deformable tube and said second deformable tube are coextruded with an adjoining portion to form a single piece. 10. The fastener cartridge assembly of claim 1, wherein said deformable tube comprises a lattice of strands woven together to form a tube wall. 11. The fastener cartridge assembly of claim 10, wherein said lattice of strands comprises tubular strands. 12. The fastener cartridge assembly of claim 10, wherein said lattice of strands comprises bioabsorbable strands. 13. The fastener cartridge assembly of claim 10, wherein said deformable tube further comprises a non-porous tube positioned one of outside and inside said lattice of strands, and wherein said non-porous tube is coextruded with said lattice of strands. 14. The fastener cartridge assembly of claim 13, wherein said lattice of strands is at least partially filled with a therapeutic agent to treat tissue. 15. 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; anda channel intermediate said top wall and said bottom wall, wherein said top wall and said bottom wall are positioned above said cartridge body; andfasteners 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. 16. The fastener cartridge of claim 15, wherein said resilient lattice comprises a first resilient lattice, wherein said fastener cartridge further comprises a second plurality of strands woven into a second resilient lattice, wherein said second resilient lattice is substantially parallel to said longitudinal axis, and wherein at least one of said first plurality of strands and said second plurality of strands comprises tubular strands. 17. 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; andfasteners 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; anda 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; anda 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. 18.
