    摘要： A method of navigating a medical device includes determining the location of a medical device at a point in an operating region in a subject's body, the medical device being responsive to at least one control variable to assume a desired configuration includes storing information representative of the at least one control variable being applied to the medical device at the point, and more preferably storing information representative of the at least one control variable and the device length.

    摘要： The present invention provides a means for guiding a medical device within the body to approach a target destination. The system and method provide a means for determining a predicted length and orientation, navigating the device to an intermediate point less than the predicted length, determining an error between the projected destination and actual target destination, and successively updating a predicted value of a control variable to yield an orientation within a predetermined distance error before advancing the device the remaining distance to the destination. This provides a physician with the capability of verifying the device will be accurately guided to the target destination without trial and error. A method is also provided for intuitive navigation to targets with limited trial and error based on user-applied device orientation adjustments, where the user chooses the magnitude of the adjustments and the system determines the adjustment direction.

    摘要： An automated system for navigating a medical device through the lumens and cavities in an operating region in a patient. The system includes an elongate medical device, having a proximal end and a distal end adapted to be introduced into the operating region. The system also includes 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. The system also includes 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. Finally, the system includes a system for orienting the medical device in a selected direction in the operating region, this system may be, for example, a magnetic navigation system which acts 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.
