Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
medtronic multi-electrode radiofrequency (rf) renal denervation system
The Medtronic Multi-electrode Radiofrequency Renal Denervation System is comprised of a single-use, disposable catheter and a reusable generator.

Primary Outcomes

Acute safety as measured by procedural complications
time frame: 1 month

Secondary Outcomes

Change in Office Systolic Blood Pressure
time frame: Baseline to 6 months

Eligibility Criteria

Male or female participants from 18 years up to 80 years old.

Inclusion Criteria: - Individual is ≥ 18 and ≤ 80 years old. - Individual has an office systolic blood pressure of 160 mmHG or greater (≥ 150 mmHg for Type 2 diabetics) based on an average of 3 office/clinic blood pressure readings - Individual is adhering to a stable medication regimen including ≥ 3 anti-hypertensive medications(preferred that one is a diuretic) for a minimum of two weeks prior to screening. Exclusion Criteria: - Individual has an estimated glomerular filtration rate (eGFR) of < 45 mL/min/1.73 m2 - Individual has type 1 diabetes mellitus - Individual requires chronic oxygen support or mechanical ventilation (e.g., tracheostomy, CPAP, BiPAP) other than nocturnal respiratory support for sleep apnea. - Individual has primary pulmonary hypertension. - Individual is pregnant, nursing or planning to be pregnant.
