Medtronic has received US FDA approval for the Symplicity Spyral™ renal denervation (RDN) system, also known as the Symplicity™ blood pressure procedure, for the treatment of hypertension.
The Medtronic Symplicity blood pressure procedure is an innovative, minimally invasive procedure that delivers radiofrequency energy to nerves near the kidneys that can become overactive and contribute to high blood pressure. After sedation, the doctor inserts a single thin tube (known as a catheter) into the artery leading to the kidney. Once the tube is in place, the doctor administers energy to the system to calm the excessive activity of the nerves connected to the kidney. The tube is removed, leaving no implant behind.
Patient preference and shared decision making have been identified as critical components of developing a hypertension care plan including the Symplicity blood pressure procedure. According to results from a Medtronic-led patient preference study, when presented with an interventional treatment with blood pressure reduction and potential risks in line with those of the Symplicity blood pressure procedure, approximately one third of patients were likely to choose the interventional treatment.
The Symplicity blood pressure procedure is safe and effective, providing significant ‘always on’ blood pressure reductions for patients. This landmark approval is the culmination of rigorous scientific study and clinical trials, including long-term, sham-controlled studies in the presence and absence of medication, and the largest real-world study,” said David Kandzari, M.D., chief, Piedmont Heart Institute and Cardiovascular Service and co-principal investigator of the SPYRAL clinical program.
The Medtronic SPYRAL HTN Global Clinical Program is the most comprehensive clinical program studying RDN and is backed by experience in more than 25,000 patients treated globally, studied in the presence and absence of medication, and in patients with high baseline cardiovascular risk. Although currently limited for investigational use in Japan, China and Canada, the Symplicity Spyral Renal Denervation System is approved for commercial use in more than 70 countries around the world.
