Summary
Brief summary
This study is a prospective, single-institution trial wherein twenty subjects with refractory hypertension will receive the experimental focused ultrasound renal denervation therapy. Safety will be assessed by incidence and evaluation of serious adverse effects associated with the investigational procedure through 52-week evaluation of bilateral treatment. Clinical utility will also be evaluated by comparison pre and post therapy systolic and diastolic blood pressure and norepinephrine spillover.
