Abstract

In various embodiments, an end effector comprising a first jaw, a second jaw, an implantable arrangement, first cavities, and second cavities is disclosed. At least one of the first and second jaws is movable to compress tissue between the first jaw and second jaws. The implantable arrangement comprises a first layer and a second layer. The first layer and the second layer comprise a polymeric composition. The first cavities are defined in the first layer and interconnectedly form a permeable first layer. The first cavities releasably retain a first therapeutic agent configured to induce a first biological response in the tissue. The second cavities are defined in the second layer and interconnectedly form a permeable second layer. The second cavities releasably retain a second therapeutic agent configured to induce a second biological response in the tissue. The first therapeutic agent and the second therapeutic agent are different.
