Abstract:
1. An ultrasonic medical treatment device comprising: a probe having a plurality of wave-generating elements each for focusing ultrasonic pressure waves at a respective linear locus of focal points extending in at least one dimension, the loci of focal points being different and spaced from each other, said wave-generating elements being translationally and rotationally stationary relative to one another, said wave-generating elements including ultrasonic electromechanical transducer elements for vibrating at least one surface to generate ultrasonic pressure waves focused along the respective loci, said wave generating elements having wave-generating surfaces of different fixed geometric shapes configured to focus ultrasonic waves along the respective loci and having longitudinal axes parallel to and spaced from the respective wave generating-surfaces, the loci of focal points of the different wave-generating surfaces being parallel to the respective longitudinal axes, said transducer elements of different ones of said wave-generating elements being independently energizable to focus ultrasonic waveform energy selectively along said different loci.
