1. A positioning system for guiding a catheter to a location where a pulmonary vein extends from an atrium, comprising:
- a transeptal sheath having a distal opening, the transeptal sheath being adapted for traversing an atrial septum;
a first guidewire adapted for slidable advancement through the distal opening in the transeptal sheath, the first guidewire having a deflectable distal portion for steering the first guidewire to a first pulmonary vein; and
a catheter adapted for advancement over the first guidewire and into the atrium the catheter being independently advancable through the sheath distal opening.
