pressure readings measured according to the BP guidelines.

2. Subject is adhering to a stable drug regimen of at least 3 different classes of
anti-hypertensive medications, including a diuretic (with no changes for a minimum of
2 weeks prior to enrollment) at optimal dose and is expected to be maintained for at
least 6 months.

3. Subject is > 18 and < 85 years of age.

4. Subject agrees to have all study procedures performed, and is competent and willing to
provide written, informed consent to participate in this study.

Key exclusion criteria
1. A secondary cause of hypertension, e.g. "white coat" hypertension (assessed by 24 h
ABPM at physician's discretion), primary aldosteronism, pheochromocytoma, renal artery
stenosis, drug induced-hypertension, Adult Polycystic kidney Disease, renal cell
carcinoma, pyelonephritis, glomerulonephritis, coarctation of the aorta, acromegaly,
Cushing's Syndrome, Conn's (primary hyperaldosteronism), polyarteritis nodosum,
systemic sclerosis, parenchymal kidney disease, obstructive sleep apnoea based on a
workup performed within the 12 months preceding enrollment.

2. Subject has aorto-ilio-femoral artery anatomy not suitable for treatment with the
investigational device(s).

3. Subject has main renal arteries that are < 20 mm in length or < 4 mm in diameter.

4. Subject has a prior history of any renal artery intervention including but not limited
to balloon angioplasty, stenting, renal denervation or surgery.

5. Subject has an estimated glomerular filtration rate (eGFR) of < 45mL/min/1.73m2, using
the MDRD formula.

6. Subject has type 1 diabetes mellitus.

7. Subject has history of Myocardial Infarction, unstable angina pectoris, or a
cerebrovascular accident in the 6 months period prior to enrolment, or documented
widespread atherosclerosis, intravascular thrombosis or unstable plaques.

8. Subject has hemodynamically significant valvular heart disease for which reduction of
blood pressure would be considered hazardous.
