1. An automated system for navigating a medical device through the lumens and cavities in an operating region in a patient, the system comprising:

  • an elongate medical device, having a proximal end and a distal end adapted to be introduced into the operating region;

    an imaging system for displaying an image of the operating region, including a representation of the distal end of the medical device in the operating region;

    a localization system for determining the position of the medical device in a frame of reference translatable to the displayed image of the imaging system;

    a magnetic navigation system for orienting the medical device in a selected direction in the operating region through the interaction of magnetic fields associated with the medical device inside the operating region and at least one external source magnet outside the patient'"'"'s body;

    an advancer acting on the proximal end of the medical device for selectively advancing the distal end of the medical device;

    an input device for receiving at least a destination for the distal end of the device input by the user using the displayed image of the imaging system;

    and a controller, responsive to the destination input by the user, for operating the magnetic navigation system to orient the distal end of the medical device in the proper orientation to reach the selected destination, and once the distal end of the medical device is in the proper orientation, operating the advancer to advance the distal end of the medical device to the destination input by the user.
