Patent ID: 7896854

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; and 3. at least one side wall extending between the back wall and the front wall; v. at least one channel originating in a surface other than the radiation surface and opening into the internal chamber; vi. a channel originating in the front wall of the internal chamber and terminating in the radiation surface; and vii. at least one protrusion located on a side wall of the chamber and extending into the chamber; b. Passing at least two different materials through the chamber; c. Mixing the materials passing through the chamber with ultrasonic vibrations emanating from the back wall of the chamber; and d. Spraying the materials onto an area of the body.
