ABSTRACT:
Transfer of substances through the skin at a treatment site is promoted by the combined effects of ultrasonic energy and positive and negative pressure. A device having a cup-shaped body is pressed against the skin; the treating substance is supplied to an interior chamber of the body, and is subjected to pressure and ultrasonic vibrational energy therewithin, while a vacuum is drawn thereabout through a surrounding annular chamber.
