摘要：A cardiac ablation device treats atrial fibrillation by directing and focusing
ultrasonic waves into a ring-like ablation region (A). The device desirably is steerable andcan be moved between a normal disposition, in which the ablation region lies parallel tothe wall of the heart for ablating a loop-like lesion, and a canted disposition, in which thering-like focal region is tilted relative to the wall of the heart, to ablate only a short,substantially linear lesion. The ablation device desirably includes a balloon reflectorstructure () and an ultrasonic emitter assembly (), and can be steered and positionedwithout reference to engagement between the device and the pulmonary vein or ostium.A contrast medium (C) can be injected through the ablation device to facilitate imaging,so that the device can be positioned based on observation of the images.
