The present invention concerns ultrasonic methods and devices for altering activity of layers of natural--or of artificial tissues and organs, and for altering activity of particular components within said layers, while minimizing alterations in neighboring layers located deeper to—or outer to—treated layer. It is carried out by focused or non focused irradiation at certain angles and preferably via cooling medium, so to at least partially create surface waves propagating in the appropriate layers, and altering their activity, while leaving the other layers essentially intact. System can allow also monitoring of beam location and of effect. The device can be constructed for either superficial treatment, or minimal invasive treatment, or layered tissues and organs. It can be used as stand alone or add on device in cosmetic and clinical applications. |
