Intervention

Device:
• Symplicity Spyral™ multi-electrode renal denervation system
After a renal angiography according to standard procedures, subjects remain blinded and are immediately treated with the renal denervation procedure after randomization.

Procedure:
• Sham Procedure
After a renal angiography according to standard procedures, subjects remain blinded and remain on the catheterization lab table for at least 20 minutes prior to introducer sheath removal.
