Abstract
This invention relates to apparatus and methods for providing and using a gel containment structure with an ultrasonic delivery system. The apparatus includes a special bladder, pad or other enclosure means for positioning adjacent the transmitting surface so that the coupling gel is retained adjacent the transmitting surface. The method for delivering ultrasonic energy includes enclosing coupling gel at the transmitting surface, positioning the enclosed coupling gel against the skin or other external location corresponding to the internal injury, and directing ultrasonic waves emitted at the transmitting surface through the enclosed conducting gel to the skin location corresponding to the internal injury.
