The SymplicityTM Renal Denervation System

Medtronic offers a novel and innovative therapy for uncontrolled hypertension. The Symplicity renal denervation system is specifically designed to deliver low-level radio frequency (RF) energy through the wall of the renal artery to achieve renal denervation (RDN).

The Symplicity renal denervation system consists of a proprietary generator and the choice of a single or multi-electrode catheter. The catheter and generator work in concert to deliver the optimal energy required to achieve blood pressure reduction for patients suffering from uncontrolled hypertension.

SymplicityTM Catheter

The Symplicity catheter delivers low-level radio frequency (RF) energy through the wall of the renal artery to achieve renal denervation. The catheter is placed in the vasculature adjacent to the target neural site using standard interventional catheter techniques. RF energy is then delivered through the catheter to the target nerves.

The Symplicity™ RDN signature helical ablation pattern is achieved with the Symplicity Flex renal denervation catheter. The energy ablation pattern of the multi-electrode design of the Symplicity Spyral renal denervation catheter is derived from the same Symplicity RDN helical signature but provides the physician with a more efficient device for energy delivery.

Symplicity Flex Renal Denervation Catheter

Symplicity FlexTM Renal Denervation Catheter

  • 6F guide-compatible steerable catheter
  • Proven safe, targeted therapy delivery
  • Self-orienting tip for confident, atraumatic vessel contact
Symplicity Spyral Multi-electrode Renal Denervation Catheter

Symplicity SpyralTM Multi-electrode Renal Denervation Catheter

  • Helical multi-electrode design delivers consistent four quadrant ablation pattern
  • Fast 60 second ablation time and simultaneous-firing electrodes
  • Self expanding design conforms to a wide range of artery shapes and sizes 3–8 mm in diameter
  • 4 F profile catheter with exceptional deliverability over a standard 0.014" guidewire

SymplicityTM Generator

Medtronic is proud to offer two distinct versions of the generator, both of which deliver precisely controlled RF energy treatments using the Symplicity catheter. The generator delivers RF energy via a dynamic algorithm that continually monitors and adjusts the powers input, taking into account impedance and temperature measurements and ensuring the delivered energy is safe and efficacious.
