The Symplicity™ Renal Denervation procedure is a minimally invasive treatment designed for individuals with high blood pressure (hypertension) that is difficult to control with medications and/or lifestyle changes alone.
High blood pressure is one of the most common causes of heart disease, stroke and kidney conditions. While most people can keep it under control, some can experience resistant hypertension.
The Symplicity Renal Denervation procedure offers an additional option for eligible patients. It is performed using a thin, flexible catheter without requiring surgery or an implant to gently reduce nerve activity in the arteries leading to the kidneys. This helps the body naturally regulate blood pressure more effectively over time.
This innovative therapy targets the overactive nerves surrounding the kidneys, called renal nerves, which influence blood pressure regulation. By calming these nerves, the Symplicity procedure can help reduce the signals that raise blood pressure, leading to a healthier and more stable cardiovascular system.
How the Procedure Works
Kidneys play an essential role in controlling blood pressure. They communicate with the brain through a network of nerves that can sometimes become overactive and send signals that keep blood pressure high.
The Symplicity procedure works by interrupting these signals in a safe, controlled way by:
- Accessing the arteries by making a small incision near the upper leg or groin. A catheter is then guided through a blood vessel to the renal arteries.
- Delivering mild radiofrequency energy to specific spots along the artery wall to calm the surrounding nerves, without damaging the artery itself.
- Restoring balance by controlling nerve activity to help the body better control blood pressure levels.
The treatment usually takes about an hour, and most patients go home the same day or after a short observation period. Patients can also return to normal activities within a few days.
Who Can Benefit
The Symplicity Renal Denervation procedure may be appropriate for adults who:
- Have high blood pressure that remains elevated despite taking multiple medications.
- Cannot tolerate certain blood pressure medications.
A comprehensive evaluation, including imaging of the renal arteries and review of medical history, will help determine if this treatment is suitable.
Clinical studies have shown that renal denervation can:
- Lower systolic and diastolic blood pressure.
- Support long-term blood pressure stability.
- Reduce the need for multiple medications in some patients.
- Provide a safe, minimally invasive treatment with no permanent implant.
Risks & Considerations
The Symplicity procedure is considered safe and well-tolerated for most patients. As with any medical procedure, there is a small risk of temporary discomfort or bruising where the catheter is inserted. Rarely, minor changes in the treated artery can occur, which can be monitored and managed by a comprehensive care team.
Your physician will review all potential risks and ensure this procedure is appropriate for your health needs.
What to Expect After the Procedure
After treatment, patients are monitored to ensure blood pressure and kidney function remain stable. Patients will receive ongoing care, including regular blood pressure checks, continued use of prescribed medications and follow-up visits to monitor results.
The Symplicity procedure is designed to work alongside any current treatment plans, to offer another way to help maintain healthy blood pressure levels and reduce the risk of long-term cardiovascular disease.
