Annular adhesive structure

An assembly for joining tissue portions, comprising:

• an anvil assembly and a body portion juxtaposed with respect to one another along a shaft, the shaft being retractable so as to approximate the anvil assembly and body portion with respect to one another;
• an applicator disposed between the body portion and anvil assembly, the applicator defining a chamber for retaining an ampoule of fluid wound treatment material therein, the applicator including a manifold and a sleeve fixedly supported on the shaft, the manifold having channels arranged for dispensing the fluid wound treatment material therefrom, wherein the channels of the manifold are oriented for directing a flow of the fluid wound treatment material onto the interface between the tissue portions, wherein each of the channels is in fluid communication with the sleeve;
• and,
• wherein the shaft and the sleeve form a plunger for compressing the ampoule and dispensing the fluid wound treatment material.
