Abstract

The present disclosure provides annular support structures for use in conjunction with stapling devices. These annular support structures may be suitable for reducing occurrences of leaking, bleeding and/or stricture, as well as anastomotic tension, when anastomosing various body structures.

Claims

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

a) an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion, wherein the tubular body portion includes at least one annular row of staples operatively disposed therein; and

b) a disk having an outer terminal portion, an inner portion aligned with the annular row of staples, and a substantially centrally located aperture, the disk being impregnated with an adhesive material at the outer terminal portion, wherein the outer terminal portion of the disk extends radially outward beyond an outer-most row of the at least one annular row of staples to adhesively attach the tissue sections together radially outward of the at least one annular row of staples and form a rim of adhered tissue around the annular row of deployed staples.

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

3. The apparatus according to claim 2, wherein the disk comprises a material selected from the group consisting of an adhesive, a sealant, a hemostat, and a medicament.

4. The apparatus according to claim 1, wherein the outer ring includes the adhesive material to adhesively attach the tissue sections together radially outward of the at least one annular row of staples.

5. The apparatus according to claim 1, wherein the disk reduces the tension exhibited on the outer-most row of the at least one annular row of staples when the adjacent tissue sections are pulled away from one another.

6. The apparatus according to claim 1, wherein the adhesive material is dispersed throughout the disk.

7. The apparatus according to claim 1, wherein the inner portion of the disk is a mesh.

8. A method of performing an anastomotic procedure on first and second annular ends of tissue, 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 arranged in an annular row and a knife;

b) deploying the annular row of staples through the first and second ends of tissue; and

c) providing a rim of adhered tissue around the annular row of deployed staples, by disposing a disk between the first and second ends of tissue prior to stapling, the disk having an outer terminal portion impregnated with an adhesive material, the outer terminal portion of adhesive disk extends radially outward beyond the annular row of staples.

9. The method according to claim 8, wherein the disk is fabricated from at least one of a bioabsorbable and a non-bioabsorbable material.

10. The method according to claim 9, wherein the disk comprises a material selected from the group consisting of an adhesive, a sealant, a hemostat, and a medicament.

11. The method according to claim 8, wherein the disk adheres the adjacent tissue sections to one another at least at a location radially outward of the outer-most row of the at least one annular row of staples.

12. The method according to claim 8, wherein the disk reduces the tension exhibited on the outer-most row of the at least one annular row of staples when the adjacent tissue sections are pulled away from one another.

13. A method of joining adjacent tissue sections, the method comprising the steps of:

a) providing a surgical stapling device including an anvil assembly having an anvil shaft, and a body portion carrying a plurality of surgical staples arranged in an annular row and a knife;

b) providing a disk having an outer terminal portion which extends radially outward beyond an outer-most row of the at least one annular row of staples, the disk being impregnated with an adhesive material at the outer terminal portion;

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

d) inserting the body portion into a second tissue section;

e) disposing the disk between the first tissue section and the second tissue section;

f) approximating the anvil assembly and body portion with one another so that the first tissue section, the second tissue section and the disk are disposed between the anvil assembly and the body portion, wherein the disk is interposed between the first tissue section and the second tissue section, and wherein the outer terminal portion of the disk extends radially outward beyond the outer-most row of the at least one annular row of staples;

g) deploying the staples from the body portion;

h) forming a rim of adhered tissue around the annular row of deployed staples; and

i) cutting the first tissue section, the second tissue section, and the disk with the knife.

14. The method according to claim 13, wherein the disk adheres the first and second tissue sections to one another.

15. The method according to claim 13, wherein the disk is fabricated from at least one of a bioabsorbable and a non-bioabsorbable material.

16. The method according to claim 15, wherein the disk comprises a material selected from the group consisting of an adhesive, a sealant, a hemostat, and a medicament.

17. The method according to claim 13, wherein the disk adheres the adjacent tissue sections to one another at least at a location radially outward of the outer-most row of the at least one annular row of staples.

18. The method according to claim 13, wherein the disk reduces the tension exhibited on the outer-most row of the at least one annular row of staples when the adjacent tissue sections are pulled away from one another.

19. The method according to claim 13, wherein the adhesive material is dispersed throughout the disk.
