Purpose
This study is to evaluate efficacy and safety of renal denervation in the treatment of uncontrolled hypertension. This study will enroll a minimum of 40 and a maximum of 45 subjects. The study will be conducted at up to 8 actively enrolling investigational sites. The primary endpoint is change in Office Systolic Blood Pressure from baseline to 6 months post-procedure.

| Experimental: Symplicity renal denervation system |
Device: Symplicity renal denervation system
Previous research has shown that disrupting the nerves of the kidney may successfully decrease blood pressure. A less invasive approach to disrupting these nerves is to apply a brief high temperature near the nerves (renal denervation). This can now be done with an experimental medical device called the Symplicity renal denervation system. The System includes a catheter that is inserted into your blood vessels and an RF-generator. |
Detailed Description:
Estimated enrollment Start: May 2013 (estimated 90 day duration) Estimated last follow-up: September 2013 Follow-Up Duration: Subjects in the intent-to-treat population will be followed from enrollment through 6 months ±14 days for the effectiveness and safety endpoints
Eligibility| Ages Eligible for Study: | 18 Years to 80 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Individual is 18 and 80 years old at time of treatment.
- Individual is receiving a stable medication regimen including 3 or more anti-hypertensive medications of different classes, of which one must be a diuretic that is expected to be maintained without changes for at least 6 months.
- Individual has an office systolic blood pressure of 160 mm Hg based on an average of 3 blood pressure readings measured at screening visits
- Individual or legally authorized representative agrees to have all study procedures performed, and is competent and willing to provide written, informed consent to participate in this clinical study.
Exclusion Criteria:
Individual has renal artery anatomy that is ineligible for treatment including:
- Main renal arteries with less than 4 mm diameter or with less than 20 mm treatable length
- Multiple renal arteries where the main renal artery is estimated to supply less than 75 percent of the kidney.
- Renal artery stenosis more than 50 percent or renal artery aneurysm in either renal artery.
- A history of prior renal artery intervention including balloon angioplasty or stenting.
- Individual has an estimated glomerular filtration rate of less than 45mL per min per 1.73m2, using the MDRD calculation.
- Individual has had more than 1 in-patient hospitalization for a hypertensive crisis within the past year.
- Individual has type 1 diabetes mellitus.
- Individual has had 1 or more episodes of symptomatic orthostatic hypotension within the past year or during the screening process.
- Individual requires chronic oxygen support or mechanical ventilation other than nocturnal respiratory support for sleep apnea.
- Individual has primary pulmonary hypertension.
- Individual has known secondary causes of hypertension, such as untreated pheochromocytoma, Cushing's Disease, coarctation of the aorta, hyperthyroidism, or hyperparathyroidism.
- Individual has experienced a myocardial infarction, unstable angina pectoris, syncope, or a cerebrovascular accident within 6 months of the screening period, or has widespread atherosclerosis, with documented intravascular thrombosis or unstable plaques.
- Individual has a scheduled or planned surgery or cardiovascular intervention in the next 6 months.
- Individual has a condition that would prohibit or interfere with ability to obtain an accurate blood pressure measurement using the protocol specified automatic blood pressure monitor
- Individual has severe cardiac valve stenosis for which, in the opinion of the Investigator, a significant reduction of blood pressure is contraindicated.
- Individual has any serious medical condition, which in the opinion of the investigator, may adversely affect the safety and/or effectiveness of the participant or the study
- Individual is pregnant, nursing or planning to be pregnant.
- Individual has a known, unresolved history of drug use or alcohol dependency, lacks the ability to comprehend or follow instructions, or would be unlikely or unable to comply with study follow-up requirements.
- Individual is currently enrolled in another investigational drug or device trial. For the purposes of this protocol, participants involved in extended follow-up trials for products that were investigational but are currently commercially available are not considered enrolled in an investigational trial.
