About

The purpose of the Spyral InSight Early Clinical Feasibility Study is to characterize the physiological response to renal nerve stimulation (RNS) in humans prior to and post renal denervation.

Full description

This study is exploratory in nature and an early-stage clinical assessment that will evaluate procedural and long-term safety of renal nerve stimulation (RNS) when performed prior to and post renal artery denervation (RDN) with the Symplicity Spyral system, with follow-up at 1, 3, 6 and 12 months.

There is no pre-specified primary endpoint. However, the objectives of the Spyral InSight ECF study are as follows:

• To assess safety of RNS when performed prior to and post RDN.
• To characterize and quantify the physiological response to renal nerve stimulation in humans undergoing renal denervation per approved labeling.
