摘要： A method of turning a medical device with the assistance of an externally applied magnetic field, in a direction with a component in a plane perpendicular to the direction of the externally applied magnetic field. The method includes applying first torque to the distal end of the medical device by creating magnetic moment at the distal end of the medical device, and applying a second torque to the distal end of the medical device. The second torque may be created by creating a second magnetic moment at the distal end of the device spaced from the first, by using an electrostrictive device, by using a stylette inserted into the device, by using a fluid-driven shaped tube, or otherwise.

摘要： A method of navigating a medical device having a changeable magnetic moment within an operating region within a patient, the method includes applying a navigating magnetic field to the operating region with an external source magnet, and changing the direction of the magnetic moment in the medical device to change the orientation of the medical device in a selected direction within the operating region. The magnet moment of the medical device can be created by one or more electromagnet coils, in which case the magnetic moment can be changed by changing the current to the coil. Alternatively, the magnetic moment of the medical device can be created by one or more permanent magnets, in which case the magnetic moment can be changed by mechanically or magnetically manipulating the permanent magnet.

摘要： A method for forming an ablation pattern to electrically isolate a vessel having an ostium from a chamber formed within a patient for treatment of cardiac arrhythmia. The distal portion of a catheter is navigated to a chamber. An anchor member is deployed from the distal end of the catheter into the chamber, and the distal end is navigated into the ostium of the vessel, and temporarily secured in the vessel. An ablation member is deployed from the distal end of the catheter into the chamber and successively navigated into contact with tissue adjacent the ostium and ablating the tissue in contact with the ablation member to form a line of ablation. At least one of the navigating the distal portion of the catheter, navigating the anchor member and navigating the ablation member is performed by applying an external magnetic field to orient the device being navigated.
