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.

Abstract: A robotic catheter system includes a controller with a master input device. An instrument driver is in communication with the controller and has a guide instrument interface including a plurality of guide instrument drive elements responsive to control signals generated, at least in part, by the master input device. An elongate guide instrument has a base, distal end, and a working lumen, wherein the guide instrument base is operatively coupled to the guide instrument interface. The guide instrument includes a plurality of guide instrument control elements operatively coupled to respective guide drive elements and secured to the distal end of the guide instrument. The guide instrument control elements are axially moveable relative to the guide instrument such that movement of the guide instrument distal end may be controlled by the master input device.

Abstract: A robotic medical system comprises an operator control station having a master input device, a catheter instrument, and an instrument driver in communication with the operator control station. The catheter instrument includes an elongate flexible catheter member, a flexible control element extending within the catheter member, and a proximal drivable assembly configured to axially move the control element relative to the catheter member to perform a kinematic function at a distal end of the catheter member. The instrument driver is configured to operate the drivable assembly to axially move the control element in response to control signals generated, at least in part, by the master input device. The drivable assembly is mounted to the instrument driver, thereby providing mechanically close relationship between the drivable assembly and the instrument driver.

Abstract: A robotic catheter system includes a controller with a master input device, and an instrument driver in communication with the controller, the instrument driver configured for independently controlling each of number of desired motions of a flexible, elongate guide instrument in a body of a patient in response to control signals generated by the controller, the desired motions selected from the group comprising axial advancement, axial retraction, axial rotation, and radial bending. Integrated haptics capability may be provided, in which one or more motors provide tactile feedback to an operator through the master input device.
