1. A remote control catheterization system comprising: a propelling device, which controllably inserts a flexible, elongate probe into the body of a patient; anda control unit, in communication with the propelling device, and comprising user controls which are operated by a user of the system remote from the patient to control insertion of the probe into the body by the propelling device,wherein the user controls include an intuitive user interface comprising a handle that can be moved longitudinally, forward and back along a single longitudinal axis, and also can be moved rotationally, in rotation around the longitudinal axis;the intuitive user interface comprising motion sensors that detect longitudinal motion and rotational motion of the handle and convert them to signals; and signal communication circuitry that communicates the signals to the control unit for commanding the propelling device to move the probe; in the same direction and distance as the handle,the intuitive user interface including a fail-safe mechanism that, when activated, allows communication between the intuitive user interface and the control console and that, when deactivated, prevents the communication, andwherein, the handle is a longitudinal member being horizontal in an operative position and being in a non-horizontal orientation in a non-operative position, the handle being operatively connected to a first contact that moves with the handle as the handle is moved from a horizontal to a non-horizontal orientation, the fail-safe mechanism including a second contact that does not move with the handle as the handle is moved from a horizontal to a non-horizontal orientation, the fail safe mechanism being implemented as two contacts in the handle that are activated when brought into contact, as the handle is moved from a horizontal to a non-horizontal position. 2. The system of claim 1 wherein the intuitive user interface is further provided with positioners that move the handle longitudinally, forward and back along its longitudinal axis, and move it rotationally, in rotation around its longitudinal axis, and wherein: the remote control catheterization system includes at least one sensor that detects forces acting longitudinally or rotationally upon the probe and communicates this feedback information to a control console;the control console is adapted to convert the feedback to commands for the positioners and send the commands to the signal communication circuits; andthe signal communication circuits are adapted to receive the commands from the processing device and send them to the positioners, which apply longitudinal or rotational forces upon the handle that replicate the longitudinal or rotational forces experienced by the probe. 3. The system of claim 2 wherein the intuitive user interface is further equipped with operator-controlled amplification circuitry that can adjust the ratio of handle movement command sent to the probe and the force feedback from the probe to the handle. 4. The system of claim 1 wherein the fail-safe mechanism is implemented as a switch that is activated when the handle is lifted up. 5. The system of claim 1 wherein the intuitive user interface is further equipped with a support base, the second contact being fixed relative to the support base, the handle and first contact being operatively pivoted to the base about a pivot. 6. The system of claim 1 wherein the intuitive user interface is further equipped with operator-controlled switches that move the handle in precise, operator-defined steps. 7. The system of claim 1 wherein the intuitive user interface is further equipped with operator-controlled switches for controlling the handle's stiffness. 8. The system of claim 1 wherein the intuitive user interface is further equipped with operator-controlled switches for controlling the ratio of handle speed to catheter speed. 9. The system of claim 1 wherein the intuitive user interface is further equipped with operator-controlled switches that send control signals via the signal communication circuits to command probe operations, including: inflating a balloon;injecting contrast agent; anddeploying a stent. 10. The system of claim 1 wherein the elongated probe is a catheter. 11. The system of claim 1 wherein the elongate probe is a stent delivery device. 12. The system of claim 1 wherein the elongate probe is an angioplasty insertion and inflation device. 13. The system of claim 1 wherein the elongate probe is a guide wire insertion device and the handle is horizontal and has a cylindrical shape. 14. A remote control catheterization system comprising: a propelling device, which controllably inserts a flexible, elongate probe into the body of a patient; anda control unit, in communication with the propelling device, and comprising user controls which are operated by a user of the system remote from the patient to control insertion of the probe into the body by the propelling devicewherein the user controls include an intuitive user interface comprising a handle that can be moved longitudinally, forward and back along a single longitudinal axis, and also can be moved rotationally, in rotation around the longitudinal axis;the intuitive user interface comprising motion sensors that detect longitudinal motion and rotational motion of the handle and convert them to signals; and signal communication circuitry that communicates the signals to the control unit for commanding the propelling device to move the probe; in the same direction and distance as the handle; anda return mechanism that, upon operator release of the handle, returns the handle to an initial longitudinal and rotational position, wherein the probe remains-fixed when the handle returns to the initial longitudinal and rotation position. 15. The system of claim 14 where the return mechanism may be selectively engaged by operator-controlled switching to determine whether the probe moves as the handle returns to its original longitudinal and rotational position. 16. A method for catheterization comprising: inserting an elongate, flexible probe into a body passage; feeding a portion of the probe outside the body into a propelling device, which advances the probe through the body passage; and controlling the propelling device to advance the probe from a location remote from the body, wherein: controlling the propelling device comprises operating an intuitive user interface comprising a handle that is moved longitudinally, forward and back along a single longitudinal axis, and also moved rotationally, in rotation around the longitudinal axis; anddetecting via motion sensors longitudinal and rotational positions of the handle and converting them to position signals;communicating the position signals to a control console, via communication circuitry, thereby commanding the propelling device to move the probe the same direction and distance as the handle was moved; andreturning, upon operator release of the handle, the handle to its original longitudinal and rotational position, and providing a control for a user to determine whether the probe moves as the handle returns to its original longitudinal and rotational position. 17.
