Abstract

A seal element for sealing between tissue lumens includes a first material for allowing tissue ingrowth and a second sealant material.

Claims

1. An assembly for disposing a seal element between tissue lumens comprising:

a circular surgical stapling device comprising an anvil assembly, a tubular body portion, and a circular knife wherein the anvil assembly comprises an anvil member and a first shaft and the tubular body portion comprises a plurality of surgical staples in a circular configuration and a second shaft disposed inwardly of the surgical staples, the first shaft being attachable to the second shaft; and

a seal element disposable between the tissue lumens, the seal element being a disc comprising an inner first material, an outer second material and a center aperture, a diameter of the center aperture being larger than the diameter of the circular knife.

2. The assembly of claim 1 wherein the inner first material is thinner than the outer second material.

3. The assembly of claim 2 wherein the inner first material is about 0.010″

to about 0.020″

thick.

4. The assembly of claim 2 wherein the inner first material comprises pores.

5. The assembly of claim 4 wherein the pores range from about 50 μ

m to about 200 μ

m.

6. The assembly of claim 1 wherein the inner first material is a foam.

7. The assembly of claim 1 wherein the inner first material is a mesh.

8. The assembly of claim 1 wherein the inner first material is a perforated sheet.

9. The assembly of claim 1 wherein the outer second material is compressible.

10. The assembly of claim 1 wherein the outer second material is expandable in response to contact with fluids.

11. The assembly of claim 1 wherein at least one of the inner first material and the outer second material further comprises at least one medically useful substance.

12. The assembly of claim 1 wherein the seal element is attachable to the first shaft or the second shaft by means of a hub.

13. The assembly of claim 1 wherein the diameter of the center aperture is about the size of the first shaft.

14. The assembly of claim 1 wherein the outer second material is connected to the inner first material via adhesive.

15. The assembly of claim 1 wherein the outer second material is connected to the inner first material via an overmold.
