26 Mar 2008TL;DR: In this article, a flexible sheath instrument, a flexible guide instrument, and a tool are described, and the tool is threaded through the guide instrument working lumen, while the sheath and guide instruments are independently controllable relative to each other.
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.

03 Jul 2006TL;DR: In this paper, an elongate guide instrument has a base, distal end, and a working lumen, wherein the guide instrument base is operatively coupled to the interface.
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.

03 Jul 2002TL;DR: In this paper, a catheter is used to induce a temperature rise in an annulus of tissue surrounding the leaflets of a valve or in the chordae tendineae sufficient to cause shrinkage, thereby causing the valves to close more tightly.
Abstract: Apparatus and methods are provided for thermally and/or mechanically treating tissue, such as valvular structures, to reconfigure or shrink the tissue in a controlled manner. The apparatus comprises a catheter in communication with an end effector which induces a temperature rise in an annulus of tissue surrounding the leaflets of a valve or in the chordae tendineae sufficient to cause shrinkage, thereby causing the valves to close more tightly. Mechanical clips can also be implanted over the valve either alone or after the thermal treatment. The clips are delivered by a catheter and may be configured to traverse directly over the valve itself or to lie partially over the periphery of the valve to prevent obstruction of the valve channel. The clips can be coated with drugs or a radiopaque coating. The catheter can also incorporate sensors or energy delivery devices, e.g., transducers, on its distal end.

17 Nov 2003TL;DR: In this paper, a robotically controlled surgical instrument includes a first jaw and a second jaw used to grasp an item, and a drive mechanism that increases the force applied to the item grasped.
Abstract: A robotically controlled surgical instrument includes a first jaw and a second jaw used to grasp an item, and a drive mechanism that increases the force applied to the item grasped. The drive mechanism and the jaws can be provided with an accommodating mechanism that allows continued movement of the drive mechanism towards a locked position even after the jaws contact a larger item so that the drive mechanism can move to the locked position when grasping items of different sizes.

06 Jul 2005TL;DR: In this paper, a robotic catheter system is used to perform a procedure on a patient, which includes generating a control signal corresponding to movement of a master input device, and moving a plurality of drive elements of an instrument driver in response to the control signal.
Abstract: A methods using a robotic catheter system to perform a procedure on a patient includes generating a control signal corresponding to movement of a master input device, and moving a plurality of drive elements of an instrument driver in response to the control signal, the drive elements operatively coupled to a corresponding plurality of control elements of an elongate guide instrument, the control elements secured to a distal end of the guide instrument and moveable axially relative to the guide instrument such that movement of the drive elements causes a corresponding movement of the guide instrument distal end.
