Symplicity Spyral

Company Ref: 

Medtronic Inc.'s CE-marked in Europe and Therapeutic Goods Administration (TGA) listing flexible 4 Fr multi-electrode Symplicity Spyral catheter and Symplicity G3 radio frequency (RF) generator are designed to significantly reduce ablation time and provide ease of deliverability during renal denervation procedures for patients with uncontrolled hypertension. The multi-electrode Spyral system leverages the proprietary Symplicity treatment algorithm and Symplicity helical ablation pattern responsible for the clinical success and safety profile of the single-electrode Symplicity renal denervation system. The Symplicity renal denervation system is available for investigational use only in the United States.  The Symplicity Spyral catheter features four electrodes that are able to deliver simultaneous or selective RF energy into the renal artery wall to disrupt the output of overactive sympathetic nerves. The new 4 Fr catheter is compatible with a 6 Fr guide catheter and is delivered over a 0.014-inch guide wire via a rapid exchange system. The Symplicity Spyral catheter is highly conformable to artery shape and size and accommodates vessel diameters of 3-8 mm. Its non-occlusive design ensures the catheter will not obstruct renal blood flow during the procedure. The Symplicity Spyral catheter is powered by a new RF generator that leverages the benefits of Medtronic’s proprietary Symplicity treatment algorithm with its built-in safety features. The system uniquely offers physicians control and flexibility with the ability to turn specific electrodes on and off to accommodate different anatomies. The G3 generator includes a new touch screen user interface compatible with the single-electrode Symplicity catheter. For more information: www.medtronic.com
