摘要：
A system for ablating tissue, said system comprising: an elongated steerable flexible shaft having a proximal portion and a distal portion an ultrasound transducer (68 124 64) coupled to the distal portion of the elongate flexible shaft, wherein the ultrasound transducer (68 124 64) emits a beam (52) of ultrasound energy to ablate target tissue (48), and wherein the beam (52) of ultrasonic energy is adapted to form a continuous lesion (162 172 174) on the target (48) tissue without contact between the ultrasound transducer (68 124 64 ) and the target tissue (48) a housing (16) coupled to the distal portion of the elongate flexible shaft dirigible, wherein the ultrasound transducer (68 124 64) is disposed adjacent the housing (16) a barrier disposed between the ultrasonic transducer (68 124 64) and tissue or adjacent blood, wherein the barrier allows the beam (52) of ultrasound energy ablation of the target (48) tissue without contact between the ultrasound transducer (68 124 64) and the objective (48) tissue, and wherein the barrier comprises a fluid flow through the housing (16) and passing the ultrasound transducer (68 124 64) to prevent blood to clot therein a handle (24) coupled to the proximal portion of the elongate flexible shaft a drive mechanism operatively coupled with the handle (24) to direct the distal portion of the elongate flexible shaft, and wherein the distal portion of the elongate flexible shaft is movable to form the continuous lesion (162 172 174) module and a catheter (30 202) having a plurality of actuators to assist movement and control of the flexible shaft elongated dirigible, module catheter (30 202) is coupled releasably to the handle (24), and wherein the module catheter (30 202) is electrically and mechanically coupled to the handle (24).Un sistema para ablación de tejido, dicho sistema comprende: un tronco flexible alargado dirigible que tiene una parte proximal y una parte distal un transductor de ultrasonidos (68 124 64) acoplado co
