An apparatus and method are provided for generating ultrasonic energy from a non-contact distance from the surface of the wound; and delivering the generated ultrasonic energy to the wound through a gaseous medium. The generated ultrasonic energy has a significantly large amplitude such that the ultrasonic energy has an intensity capable of penetrating the wound tissue to a beneficial depth to provide a therapeutic effect for decreasing the healing time for the wound.
