Method and apparatus for non-invasive treatment of hypertension by ultrasound renal denervation

摘要

Treatment area of ​​a mammalian subject, for example, in the region encompassing the renal arteries and inactivate non-invasive nerve conduction. Therapeutic ultrasound transducer (31), the subject's body outside the treatment area, preferably, is engaged with the skin of a subject in proximity to (10) treatment area. The total of (22) a relatively large impact volume or more 1cm ^3, preferably is sufficient to inactivate nerves, at a level that results in insufficient temperature to cause rapid necrosis, treatment to transmit the ultrasound energy is focused soft valid, the converter is activated. Using image processing technologies, the impact volume may be placed in the treatment area. Without having to accurately position and image processing neural individual treatment is applied are possible, for example, may be used to inactivate the renal nerves in the treatment of hypertension.
