    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 ablation instrument capable of removing blood from a treatment area is provided. The instrument includes a catheter configured to deliver a distal end thereof to a patient's heart. The instrument can also include an expandable element coupled to the distal end of the catheter wherein the expandable member is configured to be positioned adjacent a target area thereby defining a treatment area between the expandable member and the target area. Further, the instrument can include an irrigation mechanism configured to dispense an irrigation fluid from the catheter thereby displacing blood from the treatment area. Additionally, the instrument includes an energy emitter configured to deliver energy to tissue within the treatment area. The instrument can also include a contact sensor configured to determine the presence of such blood within the treatment area. Methods for ablating tissue are also provided.
