1. An apparatus for forming an anastomosis between adjacent sections of tissue, comprising:

  • a body portion;

    an anvil assembly movably mounted at a distal end of the body portion for movement toward and away from the body portion;

    an approximation assembly extending between the body portion and the anvil assembly for moving the anvil assembly toward and away from the body portion; and

    a dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including at least one angled surface defining at least one channel interposed between the anvil assembly and the body portion and being configured to dispense a fluid therefrom, wherein the dispersion assembly includes;

    a manifold having a plurality of ejection ports for dispensing wound treatment material, the channel directing the wound treatment material across the ejection ports, wherein the ejection ports include a first plurality of injection ports and a second plurality of injection ports, the first plurality of injection ports and second plurality of injection ports being directed radially outwardly, a distal end portion of the manifold being tapered at an angle relative to a longitudinal axis of the body portion,the dispersion assembly including a cap operatively connected to a distal end of the manifold in such a manner so as to define the at least one channel between an outer surface of the distal end portion of the manifold and an inner surface of the cap.
