Abstract:
1. An ultrasonic transducer device comprising: a first piezoelectric transducer; a power unit enabling an ultrasonic power beam for tissue ablation in a tissue ablation region; wherein said first piezoelectric transducer is mounted onto a base via only a preselected number of conductive mounting points; wherein electrical communication between said transducer and said bas is carried out via said conductive mounting points; wherein said mounting points are spaced apart from each other for providing at least a portion of a surface of said piezoelectric transducer with a relatively low level of damping; wherein said damping is low enough to allow vibrations to mount up so as to be suitable for increasing power transmission efficiency; and wherein said mounting points are heat conductive for transferring heat generated in said transducer.
