Adjunct material to promote tissue growth

An end effector for a surgical instrument, comprising:

• a first jaw having a cartridge body removably attached thereto, the cartridge body having on a tissue-facing surface thereof a plurality of staple cavities configured to seat staples therein;
• a second jaw having an anvil with a plurality of staple forming cavities formed on a tissue-facing surface thereof, at least one of the first and second jaws being movable relative to the other;
• a biocompatible adjunct material releasably retained on at least one of the tissue-facing surfaces of the first and second jaws and configured to be delivered to tissue by deployment of the staples in the cartridge body, the adjunct material being in the form of a fiber lattice having at least two distinct heterogeneous fiber lattice sections formed from a plurality of fibers that extend continuously between adjacent ones of the fiber lattice sections, each of the fiber lattice sections of the adjunct material being arranged in a pattern configured to promote organized tissue remodeling in a desired manner, wherein the plurality of fibers includes a first plurality of fibers extending in a first direction and a second plurality of fibers extending in a second direction that is transverse to the first direction, and wherein the first direction extends toward a radial center of the adjunct material releasably retained on the at least one of the tissue-facing surfaces of the first and second jaws, and the second direction extends around the radial center of the adjunct material releasably retained on the at least one of the tissue-facing surfaces of the first and second jaws;
• and
• an effective amount of at least one medicant disposed within and releasable from the adjunct material, each of the at least one medicants being effective to provide a desired effect on tissue in-growth in a predetermined manner, and each of the at least one medicants being releasable from the adjunct material in a homogeneous manner.
