A system for forming linear lesions in tissue, the system comprising a control unit having an ultrasound vibration driving section, and an ultrasonic applicator operatively connected to the control unit. The ultrasonic applicator comprises an ultrasonic transducer having an acoustic window, and an ultrasonic vibratory element, the ultrasonic vibratory element having a convergent shape with a focus located in the direction of the acoustic window. An air gap is adjacent to the ultrasonic vibratory element in an opposite direction from the focal point. The system further comprises means for controlling the depth of the lesion formed in the tissue.
