1. A surgical system, comprising:
an adjunct comprising:
a first bioabsorbable polymer configured to degrade at a first rate in a body of the patient, the first bioabsorbable polymer being located at a first spatial area of the adjunct; and
a second bioabsorbable polymer configured to degrade at a second rate in the body of the patient, the second bioabsorbable polymer being different from the first bioabsorbable polymer, the second rate being different from the first rate, the second bioabsorbable polymer being located at a second spatial area of the adjunct that is different form the first spatial area of the adjunct, the first and second bioabsorbable polymers forming a plurality of coatings; and
a medicant configured to facilitate healing of wounded tissue of a patient having the adjunct stapled thereto, the medicant being retained within a plurality of reservoirs formed within the adjunct, the reservoirs being sealed, pre-degradation, by at least one of the plurality of coatings,
wherein the first and second bioabsorbable polymers are configured to, pre-degradation, prevent the medicant from contacting fluid in the body of the patient,
wherein the medicant is releasable to the wounded tissue in a predetermined spatial aspect defined by the locations of the first and second bioabsorbable polymers, and
wherein degradation of the plurality of coatings is configured to cause the medicant to be released to the wounded tissue differently based on which of the plurality of coatings seals the reservoir.
