    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: A method for navigating a medical device to an anatomical surface within a subject to perform electro-anatomical mapping using a magnetic navigation system is provided that includes importing a pre-operative image data set of an anatomical surface in the subject's body into a localization system. One or more control parameters are applied to the magnetic navigation system to drive the medical device to one or more points of tissue contact, from the locations of which a geometric anatomical map can be created and registered with the pre-operative anatomical image. The pre-operative anatomical surface image and a representation of the geometric anatomical map are displayed relative to one another, such that a user may select a location on the displayed pre-operative anatomical image to navigate the medical device towards. The localization system provides the location data to the magnetic navigation system to drive the medical device to the desired location, for enabling further electrophysiology mapping or ablation treatment.

    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.

The guide wire is provided with a magnet on its distal end that can be oriented or oriented and moved by the application of a magnetic field to the magnet. A catheter or other medical device can be advanced over the guide wire. Once the medical device is in its desired position, the magnet can be withdrawn through the lumen of the catheter. Alternatively, a guide wire with a magnet on its distal end can be docked at the distal end of a catheter or medical device and can be oriented, or oriented and moved by the application of a magnetic field.
