Abstract

A seal is disclosed for installation on a port of a medical device which preferably is a trocar. A seal in accordance with present invention has a first portion which has a bore and a first outer wall of a first thickness. The base of the first portion engages the port. A seal in accordance with the present invention has a second portion with a top and a passage through the top. The second portion has a second outer wall which is integral with the first outer wall and that has a thickness at its juncture with the first outer wall that is less than the thickness of the first outer wall.

Claims

1. A seal for external attachment to a port of a medical device, comprising:

(a) a first portion with a bore, the first portion having a first outer wall of a first thickness and having a base which is formed for engagement with the port; and

(b) a second portion having a top with a passage through the top which is aligned with the bore and having a second outer wall which is integral with the first outer wall , said second outer wall having a thickness at the juncture of the first and second outer walls that is less than the thickness of the first outer wall.

2. The seal of claim 1, wherein the seal is for attachment to an access port at the proximal end of a trocar.

3. The seal of claim 1, wherein the first portion is generally tubular in shape.

4. The seal of claim 1, wherein the top comprises a plurality of spiral-like folds formed therein around said passage.

5. The seal of claim 4, wherein the normal diameter of passage in the seal is approximately 2.0 millimeters.

6. The seal of claim 5, wherein the diameter of the passage in the seal is expandable from approximately 2.0 millimeters to about thirteen millimeters without loss of sealing function.

7. The seal of claim 4, wherein it comprises a pliable material.

8. The seal of claim 7, wherein the pliable material is silicone.

9. The seal of claim 1, wherein the top comprises a plurality of circular folds formed therein, where each of the circular folds is concentric with the passage.

10. The seal of claim 9, wherein the normal diameter of the passage is approximately 2.0 millimeters.

11. The seal of claim 10, wherein the diameter of the passage is expandable from approximately 2.0 millimeters to about thirteen millimeters without loss of sealing function.

12. The seal of claim 11, wherein it comprises a pliable material.

13. The seal of claim 12, wherein the pliable material is silicone.

14. The seal of claim 1, wherein the top comprises a plurality of substantially straight, accordion-like folds which are arranged in a generally circular pattern around passage.

15. The seal of claim 14, wherein the normal diameter of the passage is approximately 2.0 millimeters.

16. The seal of claim 15, wherein the diameter of the passage is expandable from approximately 2.0 millimeters to about thirteen millimeters without loss of sealing function.

17. The seal of claim 14, wherein it comprises a pliable material.

18. The seal of claim 17, wherein the pliable material is silicone.

19. A seal for external attachment to the access port of a trocar, comprising:

(a) a first portion with a bore, the first portion having a first outer wall of a first thickness and having a base formed for engagement with the access port; and

(b) a second portion having a top and a passage through the top with folds formed in the top around the passage and having a second outer wall which is integral with the first outer wall, said second outer wall having a thickness at the juncture of the first and second outer walls that is less than the thickness of the first outer wall.

20. The seal of claim 19, wherein the folds comprise a plurality of spiral folds.

21. The seal of claim 19, wherein the folds comprise a plurality of accordion-like folds.

22. The seal of claim 19, wherein the folds comprise a plurality of circular folds where each of said circular folds is concentric with the passage.

23. A seal for external attachment to an access port at the proximal end of a trocar, comprising:

(a) a lower first portion which is generally tubular in shape with a bore and having a first outer wall with a first thickness and having a base which is formed for engagement with the access port;

(b) a second portion having a top which is generally circular in shape and having folds formed therein that extend downwardly from the top of the seal to form a passage through the top which is aligned with the bore and having a second outer wall which is integral with the first outer wall, where the second outer wall having a thickness at the juncture between the first and second outer walls that is less than the thickness of the first outer wall.

24. The seal of claim 23, wherein the folds comprise a plurality of spiral-like folds which expand downwardly from the top of the seal to the passage.

25. The seal of claim 24, wherein the normal diameter of the passage is approximately 2.0 millimeters.

26. The seal of claim 25, wherein the diameter of the passage is expandable from approximately 2.0 millimeters to about thirteen millimeters without loss of sealing function.

27. The seal of claim 24, wherein it comprises a pliable material.

28. The seal of claim 27, wherein the pliable material is silicone.

29. The seal of claim 23, wherein the folds comprise a plurality of circular folds, where each of said folds is concentric with the passage.

30. The seal of claim 29, wherein the normal diameter of the passage is approximately 2.0 millimeters.

31. The seal of claim 30, wherein the diameter of the passage is expandable from approximately 2.0 millimeters to about thirteen millimeters without loss of sealing function.

32. The seal of claim 31, wherein it comprises a pliable material.

33. The seal of claim 32, wherein the pliable material is silicone.

34. The seal of claim 33, wherein the folds comprise a plurality of substantially straight, accordion-like folds which extend downwardly from the top of the seal to the passage.

35. The seal of claim 34, wherein the normal diameter of the passage is approximately 2.0 millimeters.

36. The seal of claim 35, wherein the diameter of the passage is expandable from approximately 2.0 millimeters to about thirteen millimeters without loss of sealing function.

37. The seal of claim 34, wherein it comprises a pliable material.

38. The seal of claim 37, wherein the pliable material is silicone.
