Next-generation EnligHTN system for treating hypertension reduces total
ablation time from approximately 24 minutes to four minutes
The next-generation EnligHTN(TM) Renal Denervation System delivers simultaneous ablations via a multi-electrode catheter, reducing ablation times from approximately 24 minutes to four minutes. Image courtesy of
“The new EnligHTN system improves the procedure by significantly reducing ablation time and providing optimized ablation monitoring feedback,” said Thomas LÜscher, professor and chairman of Cardiology, at the Cardiovascular Center at the
Renal denervation is a catheter-based ablation procedure used to treat patients with drug-resistant hypertension (high blood pressure). The EnligHTN system delivers radiofrequency (RF) energy from an ablation catheter to create lesions (tiny scars) along the renal nerves – a network of nerves in the walls of the renal arteries thought to help control blood pressure. The intentional disruption of the nerve supply has been clinically found to help reduce systolic and diastolic blood pressure. The system catheter has a unique, non-occlusive basket design, helping physicians deliver a predictable treatment pattern while allowing for continuous blood flow to the kidney throughout the procedure.
Blood pressure reduction is quickly achieved by simultaneously administering 60 second ablations from all four catheter electrodes, which is typically performed two times in each renal artery. The advanced generator also has an icon-based touch screen interface that allows physicians to easily view and record procedure information.
