Abstract

An apparatus for forming an anastomosis between adjacent intestinal sections is provided. The apparatus includes an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion; and a hub for locating an annular structure between the adjacent intestinal sections. The hub includes a central sleeve defining a lumen for receiving the shaft of the anvil assembly therein. The central sleeve forms a connection portion for engaging a feature on the anastomosis device and connecting the hub to the device. The apparatus further includes an annular structure operatively connected to the sleeve and extending radially outwardly therefrom.

Claims

1. An apparatus for forming an anastomosis between adjacent intestinal sections, the apparatus comprising:

a) an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion; and

b) a hub for locating an annular structure between the adjacent intestinal sections, the hub including a central sleeve defining a lumen for receiving the shaft of the anvil assembly therein, the central sleeve forming a connection portion for engaging a feature on the anastomosis device and connecting the hub to the device, the annular structure operatively connected to the hub and extending radially outwardly therefrom.

2. The apparatus according to claim 1, wherein the hub includes an annular flange monolithically formed with and extending from the central sleeve.

3. The apparatus according to claim 2, wherein the flange extends from a first end of the central sleeve.

4. The apparatus according to claim 1, wherein the central sleeve includes a plurality of longitudinally extending slots formed around a periphery thereof.

5. The apparatus according to claim 4, wherein each elongate slot extends through one end of the central sleeve, the slots being defined by a plurality of flexible fingers.

6. The apparatus according to claim 1, wherein the annular structure is fabricated from at least one of a bioabsorbable and a non-bioabsorbable material.

7. The apparatus according to claim 6, wherein the annular structure comprises a material selected from the group consisting of an adhesive, a sealant, a hemostat, and a medicament.

8. The apparatus according to claim 1, wherein the annular structure includes an outer annular disc defining a central opening having a dimension larger than an outer diameter of the central sleeve, and a web interconnecting the disc to the central sleeve.

9. An assembly for disposing an annular structure between adjacent intestinal sections, the assembly comprising:

a) an annular surgical stapling device, having an anvil assembly and a tubular body portion, the anvil assembly having an anvil member and an anvil shaft, the tubular body portion carrying a plurality of surgical staples in an annular configuration, the tubular body portion having a connection member disposed radially inward of the surgical staples, the anvil shaft of the anvil member being attachable to the connection member of the tubular body; and

b) a hub including a central sleeve defining a lumen therethrough for selectively receiving the anvil shaft therein, and an annular structure radially extending from the central sleeve, wherein when the hub is positioned on the anvil shaft the annular structure is concentrically located with respect to a longitudinal axis of the anvil shaft.

10. The assembly according to claim 9, wherein the hub includes an annular flange monolithically formed with and extending from the central sleeve.

11. The assembly according to claim 10, wherein the flange extends from a first end of the central sleeve.

12. The assembly according to claim 9, wherein the central sleeve includes a plurality of longitudinally extending slots formed around a periphery thereof.

13. The assembly according to claim 12, wherein each elongate slot extends through one end of the central sleeve, the slots being defined by a plurality of flexible fingers.

14. The assembly according to claim 9, wherein the annular structure is fabricated from at least one of a bioabsorbable and a non-bioabsorbable material.

15. The assembly according to claim 14, wherein the annular structure comprises a material selected from the group consisting of an adhesive, a sealant, a hemostat, and a medicament.

16. The assembly according to claim 9, wherein the annular structure includes an outer annular disc defining a central opening having a dimension larger than an outer diameter of the central sleeve, and a web interconnecting the disc to the central sleeve.

17. A method of disposing an annular structure between adjacent tissue sections, the method comprising the steps of:

a) providing a surgical stapling device including an anvil assembly and a body portion, the anvil assembly including an anvil member supported on an anvil shaft and the body portion carrying a plurality of surgical staples and a knife;

b) providing a hub for locating an annular structure between the adjacent tissue sections, the hub including a central sleeve defining a lumen which is configured and adapted for selectively receiving the shaft of the anvil assembly therein, and an annular structure operatively connected to the central sleeve and extending radially outwardly therefrom;

c) inserting the anvil assembly into a first tissue section; and

d) positioning the hub onto the anvil shaft such that the annular structure is concentrically located with respect to a longitudinal axis of the anvil shaft and such that the annular structure is positioned adjacent to the first tissue section.

18. The method according to claim 17, further comprising the steps of:

a) inserting the body portion in a second tissue section;

b) approximating the anvil assembly and body portion with one another so that an end portion of the first tissue section, an end portion of the second tissue section and the annular structure are disposed between the anvil member and the body portion, wherein the annular structure is disposed between the first tissue section and the second tissue section;

c) deploying the staples from the body portion; and

d) cutting the first tissue section, the second tissue section, and the annular structure with the knife.

19. The method according to claim 17, wherein the hub includes an annular flange monolithically formed with and extending from the central sleeve.

20. The method according to claim 19, wherein the flange extends from a first end of the central sleeve.

21. The method according to claim 17, wherein the central sleeve includes a plurality of longitudinally extending slots formed around a periphery thereof.

22. The method according to claim 21, wherein each elongate slot extends through one end of the central sleeve.

23. The method according to claim 17, wherein the annular structure is fabricated from at least one of a bioabsorbable and a non-bioabsorbable material.

24. The method according to claim 23, wherein the annular structure comprises a material selected from the group consisting of an adhesive, a sealant, a hemostat, and a medicament.

25. The method according to claim 17, wherein the annular structure includes an outer annular disc defining a central opening having a dimension larger than an outer diameter of the central sleeve, and a web interconnecting the disc to the central sleeve.
