Abstract

The apparatus of one embodiment of the present invention is comprised of a flexible sheath instrument, a flexible guide instrument, and a tool. The flexible sheath instrument comprises a first instrument base removably coupleable to an instrument driver and defines a sheath instrument working lumen. The flexible guide instrument comprises a second instrument base removably coupleable to the instrument driver and is threaded through the sheath instrument working lumen. The guide instrument also defines a guide instrument working lumen. The tool is threaded through the guide instrument working lumen. For this embodiment of the apparatus, the sheath instrument and guide instrument are independently controllable relative to each other.

Claims

1. An apparatus comprising:

a flexible sheath instrument comprising a first instrument base removably coupleable to an instrument driver, said sheath instrument defining a sheath instrument working lumen;

a flexible guide instrument comprising a second instrument base removably coupleable to the instrument driver, said guide instrument positioned in the sheath instrument working lumen, and wherein said guide instrument defines a guide instrument working lumen; and

a tool positioned in said guide instrument working lumen;

wherein each of said sheath instrument, guide instrument, and tool are independently controllable relative to each other.

2. The apparatus of claim 1, wherein said tool is independently movable relative to said guide instrument such that a distal end of said tool may be extended out of, and retracted back into, a distal portion of said guide instrument lumen.

3. The apparatus of claim 1, wherein said tool comprises an electrode.

5. The apparatus of claim 1, wherein said tool comprises a grasper.

6. The apparatus of claim 1, wherein said tool comprises a scissor.

7. The apparatus of claim 1, wherein said tool comprises a needle.

8. The apparatus of claim 7, wherein said needle is retractable.

9. The apparatus of claim 1, wherein said tool comprises a collapsible basket.

10. The apparatus of claim 1, wherein said tool comprises an expandable balloon.

11. The apparatus of claim 1, wherein said tool comprises a staple applier.

12. The apparatus of claim 1, wherein said tool comprises a laser emitting element.

13. The apparatus of claim 1, wherein said tool comprises an ultrasound transducer.

14. The apparatus of claim 1, wherein said tool comprises a cryogenic cooling element.

15. The apparatus of claim 1, wherein said tool can be actuated to mechanically manipulate internal body tissue at an interventional procedure site.

17. The apparatus of claim 1, wherein said tool may be electromechanically actuated.

18. The apparatus of claim 1, wherein a distal tip of said sheath instrument comprises a localization sensor.

19. The apparatus of claim 1, wherein a distal tip of said guide instrument comprises a localization sensor.

20. The apparatus of claim 1, wherein:

said sheath instrument carries a localization sensor on a distal portion thereof; and

said guide instrument carries a localization sensor on a distal portion thereof.

21. The apparatus of claim 1, wherein said sheath instrument is robotically controlled by the instrument driver via said first instrument base.

22. The apparatus of claim 1, wherein said guide instrument is robotically controlled by the instrument driver via said second instrument base.

24. The apparatus of claim 1, wherein the instrument driver robotically controls both of said sheath instrument and said guide instrument.
