Patent ID: 7901388

Claim:
A method comprising the steps of: a. vibrating an ultrasonic horn in resonance at a frequency of approximately 16 kHz or greater comprising: i. a proximal surface; ii. a radiation surface; iii. at least one radial surface extending between the proximal end and the radiation surface; iv. an internal chamber containing: 1. a back wall; 2. a front wall; 3. at least one side wall extending between the back wall and the front wall; and 4. an ultrasonic lens within the back wall; v. at least one channel originating in a surface other than the radiation surface and opening into the internal chamber; and vi. a channel originating in the front wall of the internal chamber and terminating in the radiation surface; b. passing at least two different materials through the chamber; c. mixing the materials passing through the chamber with ultrasonic vibrations eminating from the lens within the back wall of the chamber; and d. spraying the materials onto an area of the body.
