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 compressible body having proximal and distal ends and a substantially hourglass-shaped central portion extending therebetween and including first and second lumens extending therethrough, the first lumen defining a first central longitudinal axis and the second lumen defining a second central longitudinal axis; and

a translating mechanism, separate from the compressible body and operably positioned within the compressible body between the first and second lumens for selectively translating at least one of the first and second lumens relative to each other in a lateral direction between a first position where the first and second central longitudinal axes have a first distance between them and a second position where the first and second central longitudinal axes have a second distance between them, wherein the first distance is less than the second distance.

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

3. The access assembly of claim 2, wherein the translating mechanism includes a pair of 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 one or more additional lumen.

6. The access assembly of claim 1, wherein the first central longitudinal axis is spaced the first distance from the second central longitudinal axis when the translating mechanism is in a first configuration.

7. The access assembly of claim 1, wherein the first central longitudinal axis is spaced the second distance from the second central longitudinal axis when the translating mechanism is in a second configuration.

8. The access assembly of claim 1, wherein the first and second lumens are parallel to one another.

9. The access assembly of claim 1, wherein the first lumen is at an angle with respect to the second lumen.

10. The access assembly of claim 1, wherein fluid flow between the proximal and distal ends is directed through only the first and second lumens when the first and second lumens are in the first position and the second position.

11. The access assembly of claim 1, wherein the first and second lumens are formed through the compressible body.

12. The access assembly of claim 1, wherein the compressible body defines a seal between the proximal and distal ends when the lumens are in the first position and in the second position.

13. The access assembly of claim 1, wherein the first and second lumens maintain their internal dimensions when translated between the first and second positions.

14. An access assembly comprising:

a compressible body having proximal and distal ends and a substantially hourglass-shaped central portion extending therebetween and including first and second lumens extending therethrough, the first lumen defining a first central longitudinal axis and the second lumen defining a second central longitudinal axis; and

a translating mechanism, including a pair of members, operably positioned within the compressible body between the first and second lumens for selectively translating at least one of the first and second lumens relative to each other in a lateral direction between a first position where the first and second central longitudinal axes have a first distance between them and a second position where the first and second central longitudinal axes have a second distance between them, wherein the first distance is less than the second distance.

15. The access assembly of claim 14, wherein the translating mechanism includes a drive shaft and the pair of members is a pair of links pivotable about the drive shaft.
