Abstract
One embodiment of the present invention includes advancing a transducer device through a passageway of a patient's body to a target location inside the body. The transducer device includes a piezoelectric element and an ultrasonic lens. The ultrasonic lens includes an inner surface defining a passage extending along a reference axis. The piezoelectric element is received in this passage and is acoustically coupled to the inner surface of the lens. The ultrasonic lens includes an outer surface opposite the inner surface, the outer surface defines a shape with a concave profile. While positioned at the target location, the transducer device generates ultrasonic energy and ablates tissue along at least a portion of a circumference around the transducer device at the target location by focusing the ultrasonic energy with the lens.
