Abstract (en)

[origin: WO2004016311A2] The invention relates to an assembly for improving the cavitation characteristics of layers of liquid that are close to the surface and to a flexible, adaptable, deformable ultrasonic applicator for treatment purposes. Cavitation processes in a zone close to a surface are difficult to control and maintain at a constant level during the treatment of biological systems. The efficacy of a cavitation in layers of liquid that are close to the surface can be improved by the use of a gas-enriched cavitation medium (6) and preferably an ultrasonic applicator with a film structure (10), for ultrasound in the frequency range 20 - 100 kHz, said applicator moulding particularly well to the surfaces (11) and consisting of bonded PVDF films. The inventive device and applicator are suitable for treating biological systems in the life sciences field.
