Abstract
A surgical stapler includes first and second tissue clamping members and a knife member. The first tissue clamping member is configured to receive a plurality of staples. The second tissue clamping member comprises an anvil configured to form the staples. A tissue treatment member is positionable between the first and second tissue clamping members. The tissue treatment member comprises a rupturable pouch or baffle that is configured to receive a medical fluid including at least one tissue cell. The tissue treatment member may have a spiral shape, an annular disc shape, or an elongate sleeve shape. The tissue treatment member may also include outwardly extending tabs. The tissue treatment member may also include an injection port. In use, the staples and/or the knife pierce the tissue treatment member to release at least a portion of the medical fluid held by the tissue treatment member.
