Abstract (en)
[origin: WO0035351A1] The present invention is directed to apparatus, and methods for producing homogenous cavitation. An ultrasound souce comprising an ultrasound transmitting element (20) having an axis (5), and a cross section along the axis is disclosed. The ultrasound transmitting element also has a first axial end (1), and a second axial end (2) operable to produce ultrasonic waves. The cross section has an area having a maximum value at the first axial end, and a minimum value at the second axial end. A method for producing homogenous cavitation at an area of skin comprises creating a volume of fluid having a uniformly dispersed concentration of cavitation nuclei adjacent the area of skin. Ultrasound is then applied to the volume of fluid, and causes cavitation at the cavitation nuclei.
