    Abstract: An apparatus and method for the application of ultrasound to a locations within the body are provided. The apparatus can advantageously operate at a pulse duration below about 100 milliseconds, in the range 0.1 milliseconds to 100 milliseconds, a pulse repetition period below about 1 second, and in the range of 1 millisecond to 1 second. The apparatus includes a therapeutic focused ultrasound transducer (110), activated by an electrical signal from a signal generator (120).

    Abstract: An ultrasonic treatment system and method for utilizing ultrasound to treat intravascular conditions, such as stenotic and occluded regions of blood vessels, are provided. The ultrasonic treatment system includes an ultrasonic probe (100), having a proximal and distal end. A guide catheter and guidewire may also be provided and the probe (100) can be slidably disposed within the guide catheter's inner lumen. The probe can include a horn (125) at the proximal end, a transmission member (B, C, D, E) with a proximal and a distal end connected to the horn at the transmission member proximal end (B), and a distal tip (150) connected at the transmission member's distal end. The transmission member may include one or more transmission wires (C, E), having proximal and distal ends connected serially or in parallel.

    Abstract: A control system for a probe, including a transmission member, comprises a power source for supplying a constant power to a transmission member and a transducer for coupling the constant power to the transmission member and for providing a mechanical output to the transmission member at a frequency. A frequency measuring device is also provided for constantly measuring the frequency of the mechanical output of the transducer. A current monitoring device for measuring current forwarded to the transducer which monitors the current while the frequency of said mechanical output is varied until it is determined at what frequency the current is at a maximum is also provided. A method for implementing this apparatus is also provided.
