Description of intervention(s) / exposure
Treatment: Devices - Symplicity Spyral™ multi-electrode renal denervation system
Treatment: Surgery - Sham Procedure

Experimental: Renal Denervation - Renal angiography and Renal Denervation (Symplicity Spyral™ multi-electrode renal denervation system)

Sham comparator: Sham Procedure - Renal angiography


Treatment: Devices: 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.

Treatment: Surgery: 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.
