The study was prematurely discontinued due to the low rate of enrollment.

The purpose of this study is to document safety and efficacy of renal sympathetic denervation treatment in subjects with uncontrolled hypertension by using Iberis renal denervation system.

This study is a prospective, multi-center, single-arm, non-interventional and open-label registry to collect descriptive data from patients who receive renal sympathetic denervation treatment in accordance with routine hospital practice using Iberis system.

This registry will collect data prospectively from patients that receive renal sympathetic denervation treatment with use of Iberis renal denervation system and treatment will be applied according to the routine hospital practice. No additional tests are required specific to this registry. The registry will serve as a tool to collect clinical data in order to expand the knowledge base of safety, efficacy and functionality of the Iberis system in patients with resistant hypertension.

A minimum of 30 patients will be enrolled in Europe

Inclusion Criteria:

• Age ≥18 years or minimum age as required by local regulations.

• Patient has been thoroughly informed about this registry and signed Informed Consent Form.

  • Office systolic BP higher than 160 or 150mmHg in case of type 2 diabetes
  • Ambulatory BP with average BP>130mmHg or mean daytime>135mmHg in more than 70% of the measurements.

• Patients should be on stable hypertension therapy for at least 8 weeks before procedure, including spironolactone if they are supposed to be respondent as indicated by the specialized center/excellence unit on hypertension.

Exclusion Criteria:

• Previous renal artery intervention (balloon angioplasty or stenting).
• Evidence of renal artery atherosclerosis (defined as a renal artery stenosis >50%).
• Main renal arteries of less than 4mm diameter or less than 20mm in length.
• Presence of multiple main renal arteries in either kidney.
• Estimated glomerular filtration rate <45ml/min per 1,73m2
• Recent myocardial infarction, unstable angina pectoris or cerebrovascular accident within the past 3-6 months.

Patients with uncontrolled hypertension entitled to receive renal sympathetic denervation treatment per routine hospital practice and according to relevant international, or country specific guidelines
