摘要： 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.

摘要： Methods and instruments are disclosed for creating lesions in tissue, especially cardiac tissue, for treatment of arrhythmias and the like, by employing an elastic balloon and an energy emitter, which is independently positionable within the lumen of the instrument and adapted to project a series of spots of ablative energy through a transmissive region of the balloon to a target tissue site. The energy emitter preferably is configured such the spots of energy result in a series of lesions formed in the target tissue region when the emitter is activated, the lesions having an average area ranging from about 5 mm 2 to about 100 mm 2 . In one aspect of the invention, percutaneous ablation instruments are disclosed in the form of catheter bodies having one or more balloon structures at the distal end region of the instrument and an energy emitting element, which is independently positionable and rotatable within a lumen of the instrument and adapted to project ablative energy through a transmissive region of the balloon to a target tissue site in contact with, or proximal to, the balloon surface.
