The Next Generation EnligHTNTM Renal Denervation System

As a physician who has frequent contact with patients suffering from therapy-resistant hypertension, you play an important role in identifying and treating individuals who may benefit from renal denervation. With the EnligHTN multi-electrode renal denervation system, you can offer a promising solution to patients unable to achieve safe blood pressure levels through a standard pharmacological regimen.

The EnligHTN system elevates the standard of patient care by leveraging the latest advances in cardiac ablation technology and applying them to the process of renal denervation. Developed through cutting-edge research in partnership with leading physicians worldwide, this flexible, cost-effective solution supports the effective treatment of patients suffering from uncontrolled hypertension.

A Promising Treatment

The role of the renal nerves in resistant hypertension

Catheter-based renal denervation offers you a promising treatment for resistant hypertension. Renal sympathetic nerves that surround the right and left renal arteries have been shown to play a role in regulating blood pressure. Patients with resistant hypertension have increased renal sympathetic nerve activity, which contributes to the pathophysiology of their hypertension.10-14 

The EnligHTNTM multi-electrode renal denervation system from St. Jude Medical delivers a predetermined, predictable ablation pattern to the renal artery using a single catheter, so you can offer patients with resistant hypertension an effective means for controlling high blood pressure.15 Minimal catheter manipulations minimize procedure time, and your patients should see fast results after a short recovery time.

Proven Clinical Solutions

Our clinical studies build a body of evidence required to drive change, by proving the long-term safety, effectiveness and cost-savings of our technological innovations.

The EnligHTN renal denervation system is no exception. Our clinical investigations show that this system yields successful results for patients with uncontrolled hypertension, with life-changing implications. We have engineered a safe and effective treatment for drug-resistant hypertension backed by extensive clinical support. Three main clinical studies, EnligHTN I, II and III, provide important clinical findings demonstrating the effectiveness of the system. Our clinical evidence page offers more information about these studies.

The Health and Economic Burden

The International Society of Hypertension estimates 54 percent of stroke, 47 percent of ischemic heart disease, 75 percent of hypertensive disease and 25 percent of other cardiovascular disease worldwide is attributable to hypertension.9 It affects more than 1 billion people worldwide,9 and is a major risk factor for cardiovascular morbidity and mortality.16

The danger grows substantially as a person’s blood pressure rises. In fact, the risk of cardiovascular death from ischemic heart disease, stroke and other vascular diseases doubles for every 20 mmHg systolic or 10 mmHg diastolic increase in blood pressure.6,17-19

Hypertension results in a substantial economic burden worldwide, with $500 billion in hypertension-related costs resulting from heart attack or stroke.20 Treating resistant hypertension will help lower hypertension-related costs.
