Abstract
A cardiac tissue ablation system includes an elongate catheter configured to deliver a distal end thereof to a patient's heart and an expandable member formed at the distal portion of the catheter. The expandable member has an elastic portion configured to conform to the shape of a target tissue region upon expansion. The expandable member has a plurality of inflation settings that correspond to different levels of inflation of the expandable member. The system also includes a controller for selecting an inflation setting for the expandable member and an energy emitter movably disposed within a lumen of the catheter. The energy emitter is configured to deliver radiant ablative energy to the target tissue region.
