Abstract
Methods and devices are disclosed for treating vascular stenosis using ultrasound vibrational energy from inside and outside of the balloon device into a treatment region of a patient's body. The vibrational energy is of a type and in an amount sufficient to remodel and alter compliance of the plaque at the treatment region and augment delivery therapeutic drugs to the treatment area.

1-16. (canceled)
A medical device comprising:
- a balloon catheter having a guidewire lumen and a balloon;
- an ultrasound energy transducer located outside the balloon catheter;
- an ultrasound emitting member having a proximal portion attached to the ultrasound energy transducer, and a distal portion extending longitudinally through the guidewire lumen, wherein the ultrasound emitting member delivers ultrasound energy from within the guidewire lumen and across the balloon when the balloon is inflated;
- wherein the guidewire lumen and balloon material comprise polymers having acoustic impedance less than 6.0×106 Rayl, wherein the ultrasound energy has a frequency range of 1 kHz-1 MHz, and wherein the ultrasound emitting member is freely positioned within the guidewire lumen and irrigation is provided inside the guidewire lumen during ultrasound delivery.
