Abstract: A method of navigating a magnet-tipped distal end of an elongate medical device through the body includes providing an image display of the part of the body through which the medical device is being navigated and using the display to input the desired path of the medical device by identifying points on the desired path on the display. The magnetic field needed to orient the end of the medical device in the direction of the desired path as indicated on the display is then determined. In one embodiment where only points on the desired path are identified, the field direction is the direction indicated by the points on the desired path.

Abstract: A magnetically navigable endoscope system includes an endoscope having a proximal end and a distal end, the distal end having a magnetic body; a component which transmits an image, associated with the distal end; a display component for displaying the image; a magnetic field generating apparatus for generating a magnetic field to orient the magnetic body and thus the distal end of the endoscope; and a controller coordinated with the display for controlling the magnetic field generating apparatus to selectively change the magnetic field to change the orientation of the magnetic body and thus the distal end of the endoscope.

Abstract: A device and method for specifying the orientation of a magnetic field produced in a patient to aid surgical procedures involving an implanted magnet. The device includes a processor, a pointing device, a magnet assembly generating a magnetic field, a display, and a medical imaging device that provides three-dimensional imaging of an operating region of a patient during surgery. Fluoroscopic images of an operating region of the patient in which the magnetic delivery vehicle is implanted are shown on a screen, each image representing a projection in space of the operating region. The pointing device is operated to move a cursor from a projection of a present location of the magnetic delivery vehicle to a projection of a desired future location of the magnetic delivery vehicle.
