Device for ablating body tissue A system for ablating tissue comprises an elongate flexible shaft (110) having a proximal portion, a distal portion (112) and a rotation axis; and an ultrasound transducer (114) adjacent the distal end (112) of the elongate flexible shaft (110), wherein the ultrasound transducer (114) is configured to emit a beam of ultrasound energy, The beam of ultrasound energy is configured to ablate target tissue without contact between the ultrasound transducer and the target tissue and forms a continuous lesion in the target tissue while the distal portion (112) of the elongate flexible shaft (110) is moving. |
