SYMPLICITY HTN-3 Renal Denervation in Patients With Uncontrolled Hypertension

The Symplicity HTN-3 study is a, multi-center, prospective, single-blind, randomized, controlled study of the safety and effectiveness of renal denervation in subjects with uncontrolled hypertension. Bilateral renal denervation will be performed using the Symplicity Catheter - a percutaneous system that delivers radiofrequency (RF)energy through the luminal surface of the renal artery.

Stanford is currently not accepting patients for this trial.
