Brief Summary
This study is a prospective, multi-center trial wherein each included subject will receive the experimental externally focused ultrasound renal denervation therapy. It will be conducted on a maximum of fifty patients who meet the inclusion and exclusion criteria and have signed the informed consent form. Safety is the primary endpoint of this study and will be assessed by incidence and evaluation of any serious adverse effects associated with the investigational procedure through the 52-week evaluation. Clinical utility is the secondary endpoint of this study and will be evaluated by assessing pre and post therapy systolic and diastolic blood pressure.

Outcome Measures
Primary Outcomes (1)
Safety: Incidence of Adverse Events through 52 week follow-up
Safety will be assessed by incidence and evaluation of any serious adverse effects associated with the investigational procedure through the 52-week evaluation of bilateral treatment. Included in this assessment will be the proportion of subjects with any of the following outcomes: (1) death, or (2) medical morbidity, including but not limited to renal artery aneurysm, stenosis, significant deterioration of renal function, fistulae or ureteral stenosis.

- Subject has renal stenosis greater than 50% based on baseline MRA.
- Subject has a renal stent or other implant in the region.
- Subject has kidney stones which are symptomatic and/or greater than 1cm or in the discretion of the investigator may interfere with treatment.
- Subject has a history of abdominal surgery within the past six months.
- Subject has heterogeneities in the kidney such as large cysts or tumors which in the discretion of the investigator may interfere with treatment.
