An input device for a robotic medical system includes a handle configured to be rotatable about a center axis, and to be longitudinally displaceable along the center axis. The input device also includes a deflection control element disposed on the handle and configured to selectively control deflection of the distal end of a flexible medical instrument electrically coupled to the input device. Longitudinal displacement of the handle may cause or result in a corresponding longitudinal motion or deflection of the flexible medical instrument. Rotation of the handle may cause or result in a corresponding rotation of the deflection plane. Longitudinal displacement and rotation of the handle may be detected or sensed electronically.

1. An input device for a robotic medical system including a medical instrument with a distal end, the input device comprising the following: a handle configured to be rotatable about an axis and to be longitudinally displaceable along the axis;a first sensor configured to detect axial rotation of the handle;a second sensor configured to detect longitudinal displacement of the handle along the axis;a deflection control element disposed on or about the handle and configured to communicate with an electronic control system to selectively control deflection of said distal end of said medical instrument within a deflection plane; andthe electronic control system electrically coupled to the first sensor, the second sensor, and the deflection control element, the electronic control system configured to send control signals to the medical instrument,wherein longitudinal displacement of the handle results in the electronic control unit sending control signals to the medical instrument that result in a corresponding longitudinal motion of said medical instrument and rotation of the handle results in the electronic control unit sending control signals to the medical instrument that result in a corresponding rotation of the deflection plane. 2. The input device of claim 1, wherein said medical instrument includes at least one of a catheter and a sheath, and the input device includes a selection switch configured to permit selective control of the catheter, sheath, or catheter and sheath. 3. The input device of claim 2, further comprising one or more indicators indicating whether the handle is configured to control the catheter, the sheath, or both the catheter and sheath. 4. The input device of claim 1, wherein the input device is configured to return to an initial or centered position after displacement. 5. The input device of claim 1, wherein the electronic control system comprises at least one control parameter. 6. The input device of claim 5, wherein the at least one control parameter comprises a scaling value. 7. The input device of claim 6, wherein the scaling value is 1. 8. The input device of claim 6, wherein the electronic control system is configured to accept a user defined scaling value. 9. The input device of claim 1, wherein the velocity of the displacement of said medical instrument is proportional to the magnitude of the displacement of the at least one sensor. 10. The input device of claim 1, wherein the at least one sensor is at least one of a potentiometer, a motor, and an encoder. 11. The input device of claim 1, further comprising a switch that is configured to prevent unintentional control of said medical instrument. 12. The input device of claim 11, wherein the switch comprises an optical switch or a capacitive switch configured to detect the presence or absence of a portion of a hand in contact with at least a portion of the handle. 13. The input device of claim 1, wherein a first handle having a deflection control element of a first type may be selectively removed and replaced with a second handle having a deflection control element of a second type. 14. The input device of claim 1, further configured to provide haptic feedback to a user. 15. The input device of claim 14, wherein the input device is configured to provide at least one of heat, cold, a vibration or a force to a user through the handle. 16. The input device of claim 14, wherein haptic feedback is indicative of contact of the distal of a catheter or sheath with tissue within a treatment area. 17. The input device of claim 14, wherein haptic feedback is indicative of a physical property of the input device or an associated catheter or sheath. 18. A device for controlling the robotic movement of a catheter, the device comprising the following: a catheter handle control input device including a first sensor configured to detect motion in a first manner and a second sensor configured to detect motion in a second manner; anda control system configured to receive a control signal from the first and second sensors and is configured to relate displacement of the catheter handle control input device in the first manner to a first signal corresponding advancement or retraction of at least one of a catheter and a sheath, and displacement of the catheter handle control input device in the second manner to a second signal corresponding deflection of the distal end of at least one of a catheter and a sheath along a deflection plane, wherein the control system is configured to output the first signal and the second signal to the at least one of the catheter and the sheath. 19. The device of claim 18, further comprising at least one rotary input device, wherein activation of the rotary input device results in a corresponding rotation of the deflection plane. 20. The device of claim 19, wherein rotation of the rotary input device results in a corresponding rotation of a distal end of at least one of a catheter and a sheath.
