Descriptive Information
Brief Title  ICMJE SPYRAL PIVOTAL - SPYRAL HTN-OFF MED Study
Official Title  ICMJE Global Clinical Study of Renal Denervation With the Symplicity Spyral™ Multi-electrode Renal Denervation System in Patients With Uncontrolled Hypertension in the Absence of Antihypertensive Medications (SPYRAL PIVOTAL - SPYRAL HTN-OFF MED)
Brief Summary The purpose of this study is to test the hypothesis that renal denervation decreases blood pressure and is safe when studied in the absence of antihypertensive medications.
