    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 mm2 to about 100 mm2. 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.

    摘要： A cardiac tissue ablation system according to one embodiment 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 system further includes 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. The system further includes a controller that includes a safety shut-off feature for automatically shutting off power to the energy emitter when a prescribed event occurs resulting in power to the energy emitter being stopped.

    摘要： Methods for conducting an electrophysiology procedure using a programmed machine are described, including methods for managing discrete data capture requests received throughout the course of an electrophysiology procedure and for discretizing the display of independent data capture events that occur during the course of the electrophysiology procedure. These methods enable an operator to review location maps of sites visited during the course of a procedure and to review data from discrete moments in the procedure and to play back data over a sequence of times throughout the procedure, one moment at a time. The invention further includes software constructs that enable data management.
