1. A catheter 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 catheter having a distal end navigable to the chamber, an anchor member telescopingly deployable from the distal end of the catheter and having a member for temporarily securing the anchor member in a vessel, and an ablation member telescopingly deployable from the distal end of the catheter, wherein the end of the catheter is held is place by the anchor member, and the portion of the ablation member extending from the distal end of the catheter is magnetically navigable and is capable of being pivotally oriented about the distal end of the catheter being held, to facilitate magnetic navigation of the ablation member to contact a point on the tissue surrounding the ostium of the vessel in which the anchor member is secured.
