Claim:
A surgical stapling apparatus, comprising: a body portion; an actuation assembly operatively supported at a proximal end of the body portion; a staple pusher member operatively disposed at a distal end of the body portion and being operatively connected to the actuation assembly for expelling an annular array of staples from the body portion; an anvil assembly movably mounted at the distal end of the body portion for movement toward and away from the staple pusher member; an approximation assembly extending between the body portion and the anvil assembly for moving the anvil toward and away from the tubular body portion; and a wound treatment material dispersion system for delivering wound treatment material to a target surgical site, the wound treatment material being at least one of an adhesive, a sealant, a hemostat, and a medicament, the dispersion system including: an aperture formed in the anvil assembly oriented to dispense wound treatment material in an outward direction; a source of wound treatment material in fluid communication with the aperture of the anvil assembly; and a plurality of tubular members supported within a lumen of a stem of the anvil assembly, wherein the tubular members define the source of wound treatment material, and wherein the tubular members have an undeployed condition in which the tubular members are disposed within the lumen of the stem, and a deployed condition in which the tubular members project from windows formed in the stem of the anvil assembly.
