First Claim
1. An apparatus, comprising:
- a flexible sheath instrument comprising a sheath instrument base removably coupleable to an instrument driver, said sheath instrument defining a sheath instrument working lumen;
a flexible guide instrument comprising a guide instrument base removably coupleable to the instrument driver, wherein said guide instrument is positionable in the sheath instrument working lumen and defines a guide instrument working lumen;
a tool positionable in said guide instrument working lumen, wherein said tool may be actuated by an actuator operatively coupled to the guide instrument base; and
an instrument driver having a sheath instrument interface configured for removably coupling to the sheath instrument base,wherein said sheath instrument may be robotically controlled by the instrument driver via said sheath instrument interface,wherein said instrument driver further comprises a guide instrument interface configured for removably coupling to the guide instrument base, such that movement of the guide instrument may be robotically controlled by the instrument driver via said guide instrument interface, andwherein the guide instrument interface is translatable relative to the sheath instrument interface, such that the guide instrument is axially translatable relative to the sheath instrument.

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.

17. A robotic medical instrument system, comprising:
-
a master input device; an instrument driver; a flexible sheath instrument comprising a sheath instrument base removably coupled to the instrument driver, the sheath instrument defining a sheath instrument working lumen; a flexible guide instrument comprising a guide instrument base removably coupled to the instrument driver, the guide instrument positioned in the sheath instrument working lumen and defining a guide instrument working lumen; a tool positioned in the guide instrument working lumen, wherein said tool may be actuated by an actuator operatively coupled to the guide instrument base, wherein each of said sheath instrument, guide instrument, and tool are independently controllable by the instrument driver in response to user commands entered through the master input device; and
the instrument driver comprises a sheath instrument interface configured for removably coupling to the sheath instrument base such that movement of the sheath instrument is controlled by the instrument driver via motion actuations transferred across the sheath instrument interface, the instrument driver comprises a guide instrument interface configured for removably coupling to the guide instrument base such that movement of the guide instrument is controlled by the instrument driver via motion actuations transferred across the guide instrument interface, and the guide instrument interface is translatable relative to the sheath instrument interface such that the guide instrument is axially translatable relative to the sheath instrument. - View Dependent Claims (18, 19, 20)
