Cleaning system for imaging devices

1. An apparatus, comprising:

a first tubular structure having a proximal end, a distal end, and a body extending between the proximal and distal ends, wherein the body includes a lumen for housing at least a part of an imaging device, wherein the first tubular structure is configured for attachment to a distal end of a second tubular structure, wherein the distal end of the first tubular structure includes a first opening through an outer wall of the first tubular structure, wherein the first opening is configured to drain fluid from an interior of the first tubular structure to an exterior of the first tubular structure;

a retractor that is slidable relative to the lumen;

a fluid delivery channel that is fixed in position relative to the body; and

a second opening that is in fluid communication with the fluid delivery channel;

wherein the fluid delivery channel has a first portion, and a second portion that forms an angle with an axis of the first portion; and

wherein the first opening through the outer wall of the first tubular structure and the second portion of the fluid delivery channel are aligned in a straight line and are separated by the interior of the first tubular structure.

2. The apparatus of claim 1 , wherein the retractor is configured to engage with a vessel.

3. The apparatus of claim 1 , wherein the second tubular structure is a part of a vessel harvesting device.

4. The apparatus of claim 1 , wherein the second opening is for delivering fluid towards the lumen where the imaging device is or will be located.

5. The apparatus of claim 1 , wherein the distal end of the first tubular structure has a cut-out section.

6. The apparatus of claim 1 , wherein the first tubular structure is integrally formed to include the fluid delivery channel and the second opening, wherein the second opening is located on an interior surface of the first tubular structure.

7. The apparatus of claim 6 , wherein the distal end of the first tubular structure has a cut-out section.

8. The apparatus of claim 7 , wherein the first opening is adjacent to the cut-out section.

9. An apparatus, comprising:

a first tubular structure having a proximal end, a distal end, and a body extending between the proximal and distal ends, wherein the body includes a lumen for housing at least a part of an imaging device, wherein the first tubular structure is configured for attachment to a distal end of a second tubular structure, wherein the distal end of the first tubular structure includes a first opening through an outer wall of the first tubular structure, wherein the first opening is configured to drain fluid from an interior of the first tubular structure to an exterior of the first tubular structure;

a fluid delivery channel that is fixed in position relative to the body;

a second opening that is in fluid communication with the fluid delivery channel; and

a first tissue manipulator and a second tissue manipulator that are at least partially housed within the first tubular structure, wherein the first and second tissue manipulators are not in a way of a fluid path that extends from the second opening;

wherein the fluid delivery channel has a first portion, and a second portion that forms an angle with an axis of the first portion; and

wherein the first opening through the outer wall of the first tubular structure and the second portion of the fluid delivery channel are aligned in a straight line and are separated by the interior of the first tubular structure.

10. The apparatus of claim 9 , wherein the first tissue manipulator comprises a device for cutting tissue, and the second tissue manipulator comprises a retractor.

11. The apparatus of claim 10 , wherein the device for cutting tissue comprises a first jaw and a second jaw.

12. The apparatus of claim 11 , wherein the first jaw comprises an electrically insulating material extending along a length of the first jaw, the electrically insulating material forming a lateral protrusion on the first jaw, the lateral protrusion configured for abutting and positioning a main vessel away from a portion of an adjoining branch vessel grasped between the first and second jaws.

13. The apparatus of claim 11 , wherein each of the first and second jaws comprise an electrically insulating material extending along a length of each of the first and second jaws, the electrically insulating material forming on each of the first and second jaws a lateral protrusion, the lateral protrusions configured for abutting and positioning a main vessel away from a portion of an adjoining branch vessel grasped between the first and second jaws.

14. The apparatus of claim 9 , wherein the lumen, the first tissue manipulator, and the second tissue manipulator are aligned in a straight line.

15. The apparatus of claim 9 , wherein the first tubular structure is integrally formed to include the fluid delivery channel and the second opening, wherein the second opening is located on an interior surface of the first tubular structure.

16. The apparatus of claim 15 , wherein the distal end of the first tubular structure has a cut-out section.

17. The apparatus of claim 16 , wherein the first opening is adjacent to the cut-out section.

18. The apparatus of claim 15 , wherein the first tissue manipulator comprises a device for cutting tissue, and the second tissue manipulator comprises a retractor,

wherein the device for cutting tissue comprises a first jaw and a second jaw.

19. The apparatus of claim 18 , wherein the first jaw comprises an electrically insulating material extending along a length of the first jaw, the electrically insulating material forming a lateral protrusion on the first jaw, the lateral protrusion configured for abutting and positioning a main vessel away from a portion of an adjoining branch vessel grasped between the first and second jaws.

20. The apparatus of claim 18 , wherein each of the first and second jaws comprise an electrically insulating material extending along a length of each of the first and second jaws, the electrically insulating material forming on each of the first and second jaws a lateral protrusion, the lateral protrusions configured for abutting and positioning a main vessel away from a portion of an adjoining branch vessel grasped between the first and second jaws.
