1. A compressible adjunct for use with a surgical cartridge, the compressible adjunct comprising:
a biocompatible adjunct material configured to be releasably retained on at least one of a staple cartridge and an anvil and configured to be delivered to tissue by deployment of staples in the cartridge, the adjunct material comprising a lattice main structure having at least one absorbable sub-structure formed in the lattice main structure, the at least one absorbable sub-structure configured to control fluid movement through the adjunct material such that the fluid movement impacts healing of tissue adjacent the adjunct material when the adjunct material is in a tissue deployed state;
wherein the lattice main structure comprises a plurality of unit cells having passageways therethrough, and wherein the at least one absorbable sub-structure comprises at least one microstructure formed in at least one unit cell of the plurality of unit cells for controlling fluid flow through the respective passageway.
