Abstract

An assembly for accessing a body cavity during a surgical procedure. The access assembly includes a compressible body having proximal and distal ends and a substantially hourglass-shaped central portion extending therebetween and includes first and second lumen extending therethrough. The access assembly further includes a translating mechanism operably positioned within the compressible body between the first and second lumen for selectively translating the first and second lumen relative to each other.

Claims

1. An access assembly comprising:

a body having a proximal portion, a distal portion, and a central portion extending therebetween, the body including a first lumen extending therethrough and a second lumen extending therethrough, the first lumen defining a first longitudinal axis, and the second lumen defining a second longitudinal axis; and

a translating mechanism separate from the body and operably positioned within the body, the translating mechanism selectively moves at least a portion of the first lumen relative to at least a portion of the second lumen from a first position where portions of the first and second longitudinal axes have a first distance between them, to a second position where the portions of the first and second longitudinal axes have a second distance between them, wherein the first distance is different than the second distance, and wherein a diameter of the first lumen adjacent the translating mechanism remains unchanged when the first lumen moves from the first position to the second position.

2. The access assembly of claim 1, wherein the translating mechanism includes at least one inflatable member.

3. The access assembly of claim 1, wherein the translating mechanism includes at least two inflatable members.

4. The access assembly of claim 1, wherein the translating mechanism includes a drive shaft and a pair of links.

5. The access assembly of claim 1, further including at least one additional lumen.

6. The access assembly of claim 1, wherein the first lumen and the second lumen are parallel to one another in the first position.

7. The access assembly of claim 6, wherein the first lumen and the second lumen are non-parallel to one another in the second position.

8. The access assembly of claim 1, wherein fluid flow between the proximal portion and the distal portion is always directed through only the first lumen and the second lumen when the first lumen and the second lumen are in the first position and in the second position.

9. The access assembly of claim 1, wherein the first lumen and the second lumen are formed through the body.

10. The access assembly of claim 1, wherein the body always defines a seal between the proximal portion and the distal portion when the first lumen and the second lumen are in the first position and in the second position.

11. The access assembly of claim 1, wherein the first lumen and the second lumen maintain their internal dimensions when moved between the first and second positions.

12. The access assembly of claim 1, wherein the translating mechanism selectively moves at least a portion of the first lumen in a lateral direction.

13. The access assembly of claim 1, wherein the first distance is less than the second distance.

14. The access assembly of claim 1, wherein the translating mechanism is disposed between the first lumen and the second lumen.

15. The access assembly of claim 1, wherein a diameter of the second lumen adjacent the translating mechanism remains unchanged when the first lumen moves from the first position to the second position.

16. The access assembly of claim 1, wherein a diameter of the first lumen remains unchanged along a majority of an entire length of the first lumen when the first lumen moves from the first position to the second position.

17. The access assembly of claim 16, wherein a diameter of the second lumen remains unchanged along a majority of an entire length of the second lumen when the first lumen moves from the first position to the second position.

18. An access assembly comprising:

a body having a proximal portion, a distal portion and a central portion extending therebetween, the body including a first lumen and a second lumen extending therethrough, the first lumen defining a first longitudinal axis and the second lumen defining a second longitudinal axis; and

a translating mechanism including a pair of members, the translating mechanism being operably positioned within the body between the first lumen and the second lumen for selectively moving at least a portion of the first lumen relative to the second lumen from a first position where the first and second longitudinal axes have a first distance between them, to a second position where the first and second longitudinal axes have a second distance between them, wherein the first distance is different than the second distance, and wherein a diameter of the first lumen adjacent the translating mechanism remains unchanged when the first lumen moves from the first position to the second position.

19. The access assembly of claim 18, wherein the translating mechanism includes a drive shaft, and wherein the pair of members includes a pair of links with each link being pivotable about the drive shaft.

20. The access assembly of claim 18, wherein the translating mechanism includes a pair of inflatable members.

21. The access assembly of claim 18, wherein the translating mechanism selectively moves at least a portion of the first lumen in a lateral direction.

22. The access assembly of claim 18, wherein the translating mechanism is separate from the body.

23. The access assembly of claim 18, wherein the first distance is less than the second distance.

24. The access assembly of claim 18, wherein a diameter of the second lumen adjacent the translating mechanism remains unchanged when the first lumen moves from the first position to the second position.

25. The access assembly of claim 18, wherein a diameter of the first lumen remains unchanged along a majority of an entire length of the first lumen when the first lumen moves from the first position to the second position.

26. The access assembly of claim 25, wherein a diameter of the second lumen remains unchanged along a majority of an entire length of the second lumen when the first lumen moves from the first position to the second position.

27. The access assembly of claim 18, wherein fluid flow between the proximal portion and the distal portion is always directed through only the first and second lumens when the first and second lumens are in the first position and in the second position.

28. The access assembly of claim 18, wherein the first and second lumens are formed through the body.

29. The access assembly of claim 18, wherein the body always defines a seal between the proximal portion and the distal portion when the first and second lumens are in the first position and in the second position.
