Abstract

An access assembly for insertion through a single incision is provided. The access assembly includes a foam body having a proximal end and a distal end and a plurality of lumen extending through the foam body, each of the lumen including a sleeve extending the length of the body.

Claims

1. An access assembly for insertion through tissue, the access assembly comprising:

a foam body having a proximal end and a distal end; and

a plurality of lumen extending through the flexible body, each of the lumen including a sleeve extending at least a portion of the length of the body.

2. The access assembly as recited in claim 1, wherein the body has a central portion and an upper rim at a proximal end of the central portion.

3. The access assembly as recited in claim 2, wherein the body has a lower rim at a distal end of the central portion.

4. The access assembly as recited in claim 2, wherein the upper rim has a diameter greater than a diameter of the central portion.

5. The access assembly as recited in claim 1, including three lumen.

6. The access assembly as recited in claim 1, wherein the sleeves are integrally formed with the body.

7. The access assembly as recited in claim 1, wherein the sleeves are securely affixed with the body.

8. The access assembly as recited in claim 1, wherein the sleeves define a circular cross-section.

9. The access assembly as recited in claim 1, further including one or more cannula assemblies inserted through the plurality of lumen.

10. The access assembly as recited in claim 1, wherein the sleeves are formed from one of polymer and plastic.

11. The access assembly as recited in claim 1, wherein the sleeves include a braided material.

12. The access assembly as recited in claim 1, wherein the body includes a coating that is at least one of parylene, hydrophilic, hydrophobic, bio-agents, anti-infection and analgesic.

13. A method of accessing a body cavity comprising the steps of:

creating an incision through the abdominal wall;

providing an access assembly having a foam body and a plurality of lumen extending through the body, each of the lumen including a sleeve extending the length of the body;

compressing the body such that it may be inserted through the incision;

inserting the compressed body through the incision;

releasing the compressed body to permit the body to return towards an original shape; and

receiving a cannula assembly through one or more of the plurality of lumen.

14. The method of claim 13, further including the step of receiving one or more instruments through the one or more cannula assemblies.

15. The method of claim 13, further including the step of removing the one or more cannula assemblies.

16. The method of claim 15, further including the step of receiving a valve assembly through one of the plurality of lumen.

17. The method of claim 13, wherein the body includes a Parylene coating.
