Ultrasound-enhanced stenosis therapy
First Claim
1. A method for treating stenosis or inhibiting restenosis in an artery by delivering a therapeutic agent into the artery and enhancing absorption of the therapeutic agent into a wall of the artery using ultrasound energy, the method comprising:
- emitting ultrasound energy from the ultrasound catheter, anddelivering a stenosis inhibiting therapeutic agent into the artery from the ultrasound catheter.

Abstract
Apparatus and methods are disclosed for vascular stenosis therapy, including enhancing permeability of the vessel wall using ultrasound energy and delivering a therapeutic agent into the arterial wall. Ultrasound energy may also be delivered using transcutaneous techniques and endovascular methods. In some embodiments, ultrasound energy and therapeutic agent application may be combined with angioplasty techniques and with blood flow protection devices to prevent dissipation of the therapeutic agent from the treatment site.
