Abstract: The current method and apparatus employs ultrasound beams to precisely monitor in real time the temperature of a specific segment of tissue being treated. Additionally, the current method and apparatus also provides ultrasound thermo-control of aesthetic skin treatment sessions. Such sessions may include one or more aesthetic skin tissue treatments such as sub-dermal fat cells breakdown, lessening of the amount of sub-dermal fat, tightening of loose skin, tightening and firming of body surfaces, reduction of wrinkles in the skin and collagen remodeling.

Abstract: An apparatus for cosmetic RF skin treatment where the RF energy supply is isolated from the patient treated, such that in course of treatment no undesired current flows through the subject body. The apparatus includes an applicator for fractional skin treatment that has a tip with voltage to skin delivering elements, an isolating transformer located in close proximity to the tip and one or more capacitors serially connected with the tip and output coil of the isolating transformer.

Abstract: A method for cosmetic RF skin treatment where the RF energy supply is isolated from the patient treated, such that in course of treatment no undesired current flows through the subject body. The method includes RF energy to the skin using an applicator with a tip populated by at least one voltage to skin delivering element and an isolating transformer located proximate to the tip to reduce ground currents through parasitic capacitance. The impedance of the skin is monitored during an RF treatment pulse, and operating a controller to control the delivery of an amount of energy to the skin, the amount sufficient to cause a desired skin effect. The pulse energy is increased if the skin impedance is lower than a predetermined impedance threshold; cutting off RF energy supply if the skin impedance is below a predetermined skin impedance value; and preventing pain by cutting-off RF pulses above a predetermined skin impedance value.

Abstract: An apparatus and method of a fluid containing microorganisms purification, comprising a stack of sheets each having patterns of ribs protruding from its surfaces and an embedded conductive foil connectable to a voltage source. In-between the stacked sheets the ribs engage to form fluid passageways in which electric field is generated by connecting said foils to a voltage source. The protrusions of some ribs from the sheet surface is smaller than others and they are shaped to locally amplify the electric field, thereby gate zones are formed along said passageways where the intensity of the electric field is effective for destruction of microorganisms in the fluid flow. The gate zones also deflect the fluid flow generating localized turbulence such that the time the fluid is residing along the passageway is extended and the microorganisms destruction action by the amplified electrical field is further enhanced.

Abstract: A system and method for treating skin. The System comprises one or more ultrasound transducers and one or more pairs of RF electrodes. The ultrasound transducers are adapted to focus ultrasound energy at one or more focal volumes in the skin. The RF electrodes are adapted to deliver RF energy to the one or more focal volumes.
