High blood pressure causes illness and death worldwide. Treatment of high blood pressure is usually based on lifestyle modification and blood pressure-lowering drugs. Renal denervation represents a minimally invasive approach to lower blood pressure by interrupting the nerves surrounding the renal arteries. These nerves are involved in the body's fight-or-flight and rest-and-digest systems, the so-called autonomous nervous system. The Spyral™ catheter system uses radio frequency energy to modulate renal nerve activity. Trials have consistently shown that renal denervation is safe. The first-generation catheter was a monoelectrode catheter called Symplicity Flex™ and several points in the renal artery had to be treated. The second-generation device called the Symplicity Spyral™ catheter, on the other hand, has a multielectrode design and consequently fewer ablation points are sufficient for complete denervation. Caused by the positive effects on blood pressure and the consistent safety reports, renal denervation is considered by current guidelines as an alternative and additive treatment approach in patients with high blood pressure.
