Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Device: Renal denervation (Symplicity Catheter System)
  • Diagnostic Test: Renal angiogram
