Compressible adjuncts with different behavioral zones

A compressible adjunct for use with a staple cartridge, the compressible adjunct comprising:

• a non-fibrous adjunct material formed of at least one fused bioabsorbable polymer and configured to be releasably retained on a staple cartridge and configured to be delivered to tissue by deployment of staples in the cartridge, the adjunct material comprising a lattice macrostructure having at least one drug contained therein, the lattice macrostructure being formed of a plurality of unit cells, wherein each unit cell is configured to eject a predetermined amount of drug from the adjunct material and the predetermined amount of the drug being a function of a compression profile of the respective unit cell;
• wherein each unit cell includes a plurality of sub-structures formed therein and configured to control the deformation behavior of the respective unit cell when the adjunct material is being compressed.

A compressible adjunct for use with a staple cartridge, the compressible adjunct comprising:

• a non-fibrous adjunct material formed of at least one fused bioabsorbable polymer and configured to be releasably retained on a staple cartridge 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 drug contained therein, the lattice main structure comprising first sub-structures formed in at least one first portion of the lattice main structure and second sub-structures formed in at least one second portion of the lattice main structure, wherein the first sub-structures and the second sub-structures are configured to control a first release rate and a second release rate, respectively, of the at least one drug from the adjunct material when the adjunct material is compressed and in a tissue deployed state, the first release rate being different than the second release rate.
