    摘要： A system of navigating a magnetic medical device within that part of a patient located within an operating region of the system, the system comprising magnets, and preferably electromagnets, arranged to provide a magnetic field sufficient to navigate the magnetic medical device within the operating region. There are preferably three magnetic coils arranged in mutually perpendicular planes such that their axes intersect in the operating region. The magnetic coils are sized and arranged so that a patient can easily access the operating region to allow virtually any portion of the patient to be positioned within the operating region. The openness of the magnetic system allows access to the operating region by a bi-planer imaging system.

    摘要： 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. In a second embodiment, where points on the current path and the desired path are identified, the desired angle of deflection is determined, and the direction of the magnetic field is set to lead this desired angle of deflection by 90° to over torque the end of the catheter, and the intensity of the field is determined from a table of experimentally determined field intensities for given angles of deflection. The apparatus for navigating a magnet-tipped medical device through the body in accordance with the invention includes a magnet system for applying a magnetic field to the magnet-tipped distal end of the medical device to orient the distal end of the medical device; a computer for controlling the magnet system to generate a specified magnetic field in the body part; first and second imaging devices connected to the computer, for providing bi-planar images of the body part through which the medical device is being navigated; first and second displays for displaying the images from the image devices; and an input device for inputting points identifying the desired path of the medical device on each of the displays. The computer is programmed to determine the magnetic field necessary to control orient the medical device on the path input on the displays.

    摘要： A guide for controlling the orientation of a medical device includes a cannula having a lumen therein for the medical device, and a guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement. The guide member can be magnetically responsive to an externally applied magnetic field, or can be magnetically responsive to an externally applied magnetic field when a magnetic medical device is in the passage, and/or it can be mechanically responsive.
