Abstract
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.
