An apparatus for performing medical procedures on an anatomical body includes an extension with an element near its distal end to be extended into the body, and a driver that moves the extension axially into the body, and that causes flexure of the distal end of the extension. The movement and flexure of the extension is driven by the driver from the proximal end of the extension, and an electronic controller directs the operation of the driver.

1. A system for manipulating a medical catheter instrument, comprising: a user input device; anda driver configured for removably coupling with a handle of a medical catheter instrument, and for interfacing with a control element that is externally movably coupled to the catheter handle to thereby move the control element relative to the handle to mechanically manipulate a distal end of the catheter instrument in response to user control signals generated by user actuation of the user input device. 2. The system of claim 1, wherein the user input device comprises one or more of a joystick, wheel, or dial. 3. The system of claim 1, wherein the distal end of the catheter instrument comprises one or more sensing elements. 4. The system of claim 1, wherein the distal end of the catheter instrument comprises one or more energy transmitting elements. 5. The system of claim 1, wherein the control element is rotatably coupled to the catheter handle, and wherein the instrument driver includes a drive mechanism configured to rotate the control element relative to the catheter handle in response to the user control signals. 6. The system of claim 1, wherein movement of the control element relative to the handle causes a corresponding movement of one or more control wires extending through the catheter instrument to thereby cause flexure of the distal end. 7. The system of claim 6, wherein the flexure is bi-directional in a single plane. 8. The system of claim 1, wherein the driver is further configured for axially translating the catheter instrument in response to user control signals generated by user actuation of the user input device. 9. The system of claim 1, wherein the driver is further configured for rotating the catheter instrument in response to user control signals generated by user actuation of the user input device. 10. The system of claim 1, wherein the control element is configured for being manually manipulated by a user. 11. The system of claim 1, wherein the driver is configured for both axially translating and rotating the catheter instrument in response to user control signals generated by user actuation of the user input device. 12. The system of claim 11, wherein the catheter handle has first and second control elements, and wherein the driver comprises first and second drive mechanisms configured for engaging and moving the respective first and second control elements. 13. The system of claim 11, wherein the first and second control elements are configured for being manually manipulated by a user to mechanically manipulate the distal end of the catheter instrument. 14. The system of claim 11, wherein the user input device comprises one or more of a joystick, wheel, or dial. 15. The system of claim 1, wherein the distal end of the catheter instrument comprises one or more electrophysiology elements. 16. A medical system, comprising: a catheter instrument including a handle and a flexible elongated body coupled to the handle, with one or more electrophysiology electrodes carried on a distal end of the elongated body;a user input device configured for generating user signals in response to a user actuation of the user input device;a controller configured for generating control signals in response to user signals generated by the user input device; andan automated driver removably coupled to a handle of the catheter instrument and configured for axially translating the elongated catheter body and for interfacing with a control element that is externally movably coupled to the catheter handle to thereby move the control element relative to the handle and cause flexing of the distal end of the elongated body in response to the control signals generated by the controller. 17. The medical system of claim 16, wherein the driver is further configured for rotating the elongated body about a longitudinal axis in response to control signals generated by the electrical controller. 18. The medical system of claim 16, wherein the driver is configured for bi-directionally flexing the distal end of the elongate body in a single plane. 19. The medical system of claim 16, wherein the driver is configured for flexing the distal end of the elongated body in orthogonal planes. 20. The medical system of claim 16, wherein the driver includes a first drive mechanism configured for axially translating the elongated body, a second drive mechanism configured for flexing the distal end of the elongated body. 21. The medical system of claim 20, the driver further including a third drive mechanism for rotating the elongated body about a longitudinal axis. 22. The system of claim 1, wherein the control element is configured for touch by a user.
