This is the turning point in hypertension care

Lifestyle changes and medications have defined hypertension care — until now. See how the Symplicity Spyral RDN system complements existing hypertension treatment protocols, review clinical evidence, and sign up to receive resources directly through email.



Introducing the Symplicity Spyral RDN system

Current hypertension care strategies are not always enough to help patients achieve blood pressure control. The Symplicity Spyral RDN system is used during the Symplicity™ blood pressure procedure — the first catheter-based approach using radiofrequency (RF) energy that complements medications and lifestyle modifications to help reduce blood pressure.

Watch a short video to see why we’ve spent the last 10 years dedicated to developing an alternative solution to manage this disease.

Evidence showing safety and efficacy

The Symplicity Spyral RDN system is proven to achieve significant, safe, and sustained blood pressure reductions in the presence and absence of medications in multiple clinical trials and a real-world patient registry.1–4


> 9


mean reduction in office systolic blood pressure (SBP) in patients on and off medications at primary endpoint follow-up in multiple clinical trials*1,2


< 0.4%

major adverse events at composite endpoint including zero incidents of renal artery stenosis2




mean reduction in office SBP real-world patients at three years with the Spyral catheter, n = 267*5

How the system works

The Symplicity Spyral RDN system is comprised of the Symplicity Spyral multi-electrode renal denervation catheter and the Symplicity G3™ renal denervation RF generator.

Patients whose blood pressure is difficult to control may have an overactive sympathetic nervous system. The Symplicity procedure aims to suppress this inappropriately elevated sympathetic drive. The Symplicity Spyral system offers a versatile, simple, and minimally invasive method to perform renal denervation.6

The procedure is performed by interventionalists due to its similarity to other procedures they perform every day.


Patient selection considerations

Understanding which patients could benefit from the Symplicity procedure is an important step when considering this therapy.

Your patients may benefit if they:

Have uncontrolled

Consider patients where lifestyle modifications and antihypertensive medications haven’t adequately controlled blood pressure.

Are willing to undergo
an interventional procedure

Consider patients who opt for the Symplicity procedure following shared decision-making and an attempt at lifestyle modifications and medical therapy.
