Abstract

A system for extending the visual capabilities and working channel of a bronchoscope including a probe having optic and/or tracking capabilities at a distal tip thereof and capable of being advanced through the working channel of a standard bronchoscope. The probe also includes a working channel through which various diagnostic and treatment tools may be advanced.

Claims

1. A probe for use through a working channel of a bronchoscope comprising:

a catheter body having a proximal end and a distal end, said body having an outside diameter of less than 2.65 mm such that it may pass through a working channel of a bronchoscope;

a tool lumen extending through said catheter body;

an optical assembly, usable to communicate visual imagery data to a monitor of an optical scope system;

a tool passable through said tool lumen and extendable from the distal end of the catheter body.

2. The probe of claim 1 further comprising a location sensor in said catheter body distal end, said location sensor usable in combination with a location system for determining a location and orientation of said probe distal end.

3. The probe of claim 1 wherein said location sensor comprises an active sensor.

4. The probe of claim 1 wherein said location sensor comprises a passive sensor.

5. The probe of claim 3 wherein said active sensor comprises a magnetic field generator.

6. The probe of claim 4 wherein said passive sensor comprises at least one coil responsive to a magnetic field.

7. The probe of claim 1 wherein said location sensor comprises a 6 degree of freedom sensor.

8. The probe of claim 1 wherein said optical assembly comprises an objective lens.

9. The probe of claim 8 wherein said optical assembly further comprises at least one light source.

10. The probe of claim 8 wherein said optical assembly further comprises a sealed optic window.

11. The probe of claim 1 wherein said optical assembly comprises an optical assembly that operates within the visible spectrum.

12. The probe of claim 1 wherein said optical assembly comprises an infrared optical system.

13. The probe of claim 10 wherein said optic window is flush with a distal end of said probe.

14. The probe of claim 10 wherein said optic window is convex and said objective lens protrudes from a distal end of said probe.

15. The probe of claim 8 wherein said objective lens comprises a CMOS lens.

16. The probe of claim 8 wherein said objective lens comprises a fiberscope.

17. The probe of claim 8 wherein said objective lens comprises a microvideo lens.

18. The probe of claim 8 wherein said objective lens comprises a hybrid between a fiberscope and a video lens.

19. The probe of claim 1 wherein said optical assembly comprises a plurality of light sources.

20. The probe of claim 19 wherein said plurality of light sources comprises a plurality of light fibers.

21. The probe of claim 20 wherein said light fibers terminate at a floor of said optical assembly.

22. The probe of claim 1 wherein said optical assembly comprises an optical window and a floor spaced apart from said optical window.

23. The probe of claim 22 wherein said optical assembly further comprises walls extending between said floor and said optical window.

24. The probe of claim 23 wherein said walls comprise reflective material.

25. The probe of claim 1 further comprising an optic cleaning system.

26. The probe of claim 25 wherein said optic cleaning system comprises a nozzle directed toward said optical assembly.

27. The probe of claim 26 wherein said optic cleaning system comprises a reservoir located near a proximal end of said probe, in fluid communication with said nozzle.

28. The probe of claim 1 further comprising a tool, extendable from said distal end.
