Arm | Intervention/treatment |
---|---|
Experimental: Ultrasound Renal Denervation
Subjects in the TRIO or SOLO cohorts that are randomized to treatment, will receive renal denervation following a renal angiogram
|
Device: The Paradise® Renal Denervation Ultrasound System
Randomization will occur following the diagnostic renal angiogram. Blinded patients randomized to treatment will receive the renal denervation procedure using the Paradise System to deliver ultrasound energy to thermally ablate and disrupt the renal sympathetic nerves while sparing the renal arterial wall.
Other Name: renal denervation |
Sham Comparator: Sham Procedure
For subjects in TRIO or SOLO cohorts that randomize to the sham procedure, the diagnostic renal angiogram intervention will be considered the sham procedure.

Device: Sham Procedure
Randomization will occur following the diagnostic renal angiogram. For blinded patients randomized to control, the diagnostic renal angiogram will be considered the sham procedure.
