1. A stapling system for stapling tissue, comprising:
a cartridge, comprising:
a deck;
staple cavities defined in said deck; and
staples removably stored in said staple cavities;
an anvil configured to deform said staples; and
a buttress, comprising:
a first layer comprised of a first absorbable polymer, wherein said first layer comprises a first compactness of first fibers;
a first medicament embedded in said first compactness of said first fibers of said first layer;
a second layer comprised of a second absorbable polymer which is different than said first absorbable polymer, wherein said second layer comprises a second compactness of second fibers different than said first compactness of said first fibers, and wherein said second layer co-operates with said first layer; and
a second medicament embedded in said second compactness of second fibers of said second layer which is different than said first medicament, wherein said second medicament co-operates with said first medicament;
wherein said first medicament is released at a first rate as a result of said first compactness of said first fibers, and wherein said second medicament is released at a second rate as a result of said second compactness of said second fibers which is different than said first rate.
