| 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. |
