ABSTRACT:
An apparatus for removing atherosclerotic plaque includes a probe attachable to an ultrasound transducer and a catheter surrounding a transmission part of the probe for conveying liquid to the working part of the probe. Preferably, the catheter is made from a material having a negligible coefficient of friction relative to the liquid so that oscillation of the probe is not damped by surrounding tissue or by the catheter. The catheter is arranged so that the liquid wets the entire working part of the probe even when the working part is extended deep inside a vessel.
