摘要：
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.
