摘要：
An ultrasound catheter may be adapted for placement within a blood vessel having a vessel wall for treating a vascular lesion within or adjacent the vessel wall. The ultrasound catheter includes an elongate shaft extending from a distal region to a proximal region and an ultrasound transducer that is disposed relative to the distal region of the elongate shaft and is adapted to impart near-field acoustic pressure waves upon the vascular lesion in order to mechanically modify the vascular lesion. An inflatable balloon is disposed about the ultrasound transducer and is coupled to the elongate shaft, the inflatable balloon having a collapsed configuration suitable for advancing the ultrasound catheter through a patient's vasculature and an expanded configuration suitable for anchoring the ultrasound catheter in position relative to a treatment site.
