Abstract

A tissue thickness compensator may generally comprise a first layer comprising a first medicament, a second layer comprising a second medicament, and a third layer comprising a third medicament. The tissue thickness compensator may comprise a first layer comprising a first medicament, a second layer comprising a second medicament, and a reservoir comprising a third medicament disposed within the reservoir. The medicaments may be independently selected from a haemostatic agent, an anti-inflammatory agent, an antibiotic agent, anti-microbial agent, an anti-adhesion agent, an anti-coagulant agent, a pharmaceutically active agent, a matrix metalloproteinase inhibitor, and combinations thereof. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.
