Abstract: A high power ultrasound application device (1) is provided which comprises a hand-held applicator (3). The applicator comprises a converter element (5) for converting electric signals into ultrasound waves; a treatment head (6) configured to apply ultrasound waves from the converter element to a subject to be treated; a handle (8) for holding and manipulating the applicator; and an oscillator circuit (9) arranged in the applicator and comprising one or more electronic components (10A, 10B) configured to be energized by a power source and to generate an output signal to drive the converter element. The oscillator circuit is in thermal contact with the handle, and the handle comprises a heat conductivity and thermal coefficient such that, when manually held by an operator in normal use, a heat conductive channel is provided between at least a portion of the circuit and the operator.

Abstract: An ultrasound treatment head for an apparatus for treating a patient with ultrasound comprises at least one active element for converting an electric signal into ultrasound and a vacuum cup having an upper part and a lower part. The active element is mounted in the upper part and the vacuum cup provides a vacuum chamber with a holding space for a gel pad. The upper part is adapted to act as a spring suspension for the active element to lower the active element into the lower part. The active element is provided with a positioning ring protruding with respect to the active element. This positioning ring determines the location of the gel pad within the holding space.
