Abstract
A system for ablation with acoustic feedback comprises: a catheter which includes an elongated catheter body; at least one ablation element to ablate a targeted tissue region; and a pulse-echo ultrasonic transducer arranged to emit and receive an acoustic beam along a centroid in a beam direction, at a transducer beam angle of between about 30 degrees and about 60 degrees relative to a distal direction of the longitudinal axis at a location of intersection between the longitudinal axis and the beam direction of the centroid of the acoustic beam of the ultrasonic transducer, wherein the transducer transmits and receives acoustic pulses to provide lesion information in the targeted tissue region; an ablation power subsystem; an ultrasonic transmit and receive subsystem to operate the ultrasonic transducer; a control subsystem to control operation of the ablation power subsystem and the ultrasonic transmit and receive subsystem; and a display.
