    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: The present invention provides devices and methods for the treatment of atrial fibrillation. In one embodiment method for treatment of atrial fibrillation is provided that includes positioning a sheath catheter having a deflectable distal end segment in the left atrium of a heart, orienting said sheath catheter such that an ablation instrument can be delivered through the sheath catheter to a position proximal to a first pulmonary vein, activating the ablation instrument to form a circumferential lesion around the first pulmonary vein, repositioning the sheath catheter by deflecting the distal end segment to another orientation, and activating the ablation instrument to form a circumferential lesion around at least one additional pulmonary vein.

    摘要: An apparatus and method for treating a cardiac condition with visual inspection of a tissue treatment site includes the step of delivering an expanding member formed on a distal end of a catheter to a position adjacent a tissue treatment area within a patient's heart. The expandable member has an elastic portion configured to conform to the tissue treatment area. The method further includes the steps of expanding the expandable member thereby allowing the elastic portion of the expandable member to conform to the tissue treatment area and positioning an energy emitter at a first location within an inner lumen of the catheter. A visible aiming beam is projected during positioning of the energy emitter and ablative energy is delivered from the energy emitter to the tissue treatment area thereby resulting in a first spot lesion. The ablative energy is coincident with the aiming beam and the aiming beam is in the form of pulsed visible light to allow intermittent visual inspection of the first spot lesion at times when the aiming beam is not projected onto the tissue treatment area, thereby allowing visual inspection of the ablative characteristics and sufficiency of the first spot lesion.
