Medtronic Symplicity Spyral Multi-Electrode Renal Denervation RDN System Catheter

The Symplicity Spyral™ renal denervation (RDN) system is used during the Symplicity™ blood pressure procedure for the treatment of hypertension.

During the Symplicity™ blood pressure procedure, an interventionalist uses the Symplicity Spyral™ RDN system to supply precisely controlled and targeted radiofrequency (RF) energy to the renal nerves, safely disrupting the overactive sympathetic signaling between the kidneys and brain to help reduce blood pressure.

Additional Details

• Company Name: Medtronic, Inc.
• FDA Product Code: QYI
• FDA Product Code Name: Ablation catheter, renal denervation
• GMDN Term Code: 58893
• GMDN Term Name: Renal denervation radio-frequency ablation catheter
• GMDN Term Definition: A sterile, steerable, thin, flexible tube containing one or more monopolar electrodes intended to be introduced percutaneously into the renal artery to transmit precisely-focused, low-level, radio-frequency (RF) current, from a connected RF generator, to disrupt renal nerves for therapeutic denervation of the kidney; commonly known as renal denervation (RDN). The device has embedded metallic electrodes and may be available in a variety of forms (e.g., deflectable tip, balloon catheter). This is a single-use device.

Radiofrequency (RF) Ablation is a widely used thermal ablation technique that destroys targeted tissue by delivering high-frequency alternating current through a catheter or probe. The electrical energy creates heat, leading to localized coagulative necrosis and cell death. In cardiology, RF ablation is a cornerstone treatment for arrhythmias like atrial fibrillation, while in oncology, it’s used to treat tumors in the liver, kidney, lung, and other organs. RF ablation is valued for its precision, proven track record, and ability to be performed in a minimally invasive setting, often under imaging guidance.

Medtronic’s former Minimally Invasive Therapies Group (MITG), now part of the Surgical and Endoscopy Operating Units within the Medical Surgical Portfolio, focuses on advanced technologies that support minimally invasive procedures across general, bariatric, colorectal, and thoracic surgery. The portfolio includes a wide range of surgical stapling systems like the Signia and Endo GIA platforms, energy devices such as the LigaSure vessel sealing system and Valleylab electrosurgical generators, as well as a robust line of trocars, sutures, and advanced instrumentation. MITG also includes market-leading solutions in gastrointestinal diagnostics and respiratory monitoring, including the Bravo pH monitoring system and the Puritan Bennett ventilators. Medtronic’s innovations in this space aim to improve surgical precision, reduce complications, and enhance recovery through technology-driven, value-based care.
