Abstract
An ultrasonic catheter comprises a catheter body having an interface surface which extends at least partially over a circumferential portion of the catheter body. The interface surface is coupled to an oscillating driver so that axial and/or radial oscillations are radiated into a fluid environment surrounding the catheter body. Optionally, the catheter may be provided with a fluid infusion lumen and/or inflatable balloons on either side of the interface surface in order to deliver treatment fluid within a specific or isolated region in a body lumen.
