<p>A probe for ultrasonic tissue treatment includes a longitudinally extending body for transmitting ultrasonic vibrations. A surface of the body includes a plurality of openings configured and arranged to decrease the mass of the body in a distal direction to provide velocity amplification of the ultrasonic vibrations. The openings increase in size in a distal direction by varying in shape from round to oval. The openings can be arranged equally spaced, offset, or in a spiral.</p> |
