Abstract: Medical devices and method for making and using medical devices are disclosed. An example method for treating a blood vessel may include disposing a medical device within the blood vessel at a position adjacent to a lesion. The medical device may include an elongate shaft having a distal end region, a balloon coupled to the distal end region, and a cavitation member disposed within the balloon. The method may also include inflating the balloon to a first pressure, activating the cavitation member, and inflating the balloon to a second pressure greater than the first pressure.

Abstract: 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.
