Abstract

An assembly for joining tissue is provided and includes an anvil assembly and a body portion juxtaposed with respect to one another along a shaft and arranged so as to be approximated with respect to one another; and an applicator supported on the anvil assembly and configured for retaining a wound treatment material therein and for dispensing the wound treatment material therefrom. A method for joining tissue is provided and includes the steps of dispensing the wound treatment material from the applicator so as to distribute wound treatment material onto at least one of a first tissue section and a second tissue section; and approximating the anvil assembly and the body portion to one another so that the first tissue section and the second tissue section are in contact with one another with the dispensed wound treatment material interposed there between.

Claims

1. 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; and

an applicator disposed between the body portion and anvil assembly, the applicator including a manifold and a sleeve fixedly supported on the shaft wherein a fluid wound treatment material is retained within and dispensed from the sleeve, the manifold having channels arranged for dispensing the fluid wound treatment material therefrom onto an interface between the tissue portions disposed between the anvil assembly and the body portion,

wherein each of the channels is in fluid communication with the sleeve and an ampoule disposed in the sleeve; and

,

wherein the shaft and the sleeve form a plunger for compressing the ampoule and dispensing the fluid wound treatment material.

2. The assembly according to claim 1, wherein the fluid wound treatment material is at least one of an adhesive, a sealant, a hemostat, and a medicament.

3. The assembly according to claim 1, wherein the manifold extends radially outward from the shaft and wherein each channel is formed therein and radially outwardly directs a flow of the fluid wound closure material.

4. The assembly according to claim 1, wherein the applicator includes a seal interposed between the sleeve and the ampoule.

5. The assembly according to claim 1, wherein the sleeve includes a portion through which the interior of the sleeve is visible.

6. The assembly according to claim 5, wherein the portion of the sleeve comprises an aperture.

7. The assembly according to claim 5, wherein the portion of the sleeve comprises a window.

8. The assembly according to claim 5, wherein the ampoule comprises a cartridge for containing the fluid wound treatment material.

9. The assembly according to claim 8, wherein the cartridge is arranged to direct the fluid wound treatment material in a distal direction.

10. 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.

11. The assembly according to claim 10, wherein the fluid wound treatment material is at least one of an adhesive, a sealant, a hemostat, and a medicament.

12. The assembly according to claim 11, wherein the fluid wound treatment material is retained within and dispensed from the sleeve.

13. The assembly according to claim 10, wherein the manifold extends radially outward from the shaft and each channel radially outwardly directs the flow of the fluid wound treatment material.

14. The assembly according to claim 10, wherein the applicator includes a seal interposed between the sleeve and the ampoule.

15. The assembly according to claim 10, wherein the applicator and the shaft are complementarily configured to form a releasable connection therebetween.

16. The assembly according to claim 10, wherein the body portion carries a plurality of surgical staples in an annular configuration, the surgical staples being deployable against an anvil of the anvil assembly.

17. The assembly according to claim 16, further comprising an annular knife disposed radially inwardly of the surgical staples.
