1. A surgical system, comprising:
an adjunct configured to be released from an end effector of a surgical stapler and stapled to tissue of a patient, the adjunct including an upper outer wall, a lower outer wall, and a plurality of heterogeneous fiber lattice sections, wherein
each of the fiber lattice sections is formed from a plurality of fibers that extend between and interconnect the upper outer wall and the lower outer wall,
each of the upper and lower outer walls are formed from a synthetic material, and
each adjacent pair of the fiber lattice sections defines a reservoir therebetween such that the adjunct includes one or more reservoirs; and
a hemostatic agent configured to promote hemostasis, wherein
the hemostatic agent is disposed in each of the one or more reservoirs, and
the upper and lower outer walls are configured to degrade in the patient from a first state, in which the upper and lower outer walls prevent the hemostatic agent from being released from the one or more reservoirs, to a second state, in which the upper and lower outer walls allow the hemostatic agent to be released from the one or more reservoirs and into contact with the tissue.
