18-80 years
Phase:
NA
Brief Summary
The objective of the study is to evaluate the safety of renal denervation using the iRF System and to understand any potential improvement in hypertension.
Detailed Description
This study is a prospective, single-arm, multi-center, non-randomized trial to evaluate the initial safety and performance of renal denervation with the iRF system for the treatment of hypertension.
Eligibility Criteria
Inclusion
- Age ≥ 18 and ≤ 80 years old
- Office SBP ≥ 140 and \< 180 mmHg on a stable dose of antihypertensive medication(s) for at least 30 days
- Documented daytime systolic ABP ≥ 135 and \< 170 mmHg
- Waist circumference ≥ 102 cm (male) and ≥ 88 cm (female)
Exclusion
- Renal artery anatomy on either side, ineligible for treatment including the following:
- Main renal artery diameter \< 4.0 mm or \> 7.0 mm
- Main renal artery length \< 20.0 mm
- Only one functioning kidney
- Presence of abnormal kidney tumors
- Renal artery with aneurysm
- Pre-existing renal stent or history of renal artery angioplasty
- Fibromuscular disease of the renal arteries
- Presence of renal artery stenosis of any origin ≥ 30 %
- Individual lacks appropriate renal artery anatomy
- Prior renal denervation procedure
- Iliac/femoral artery stenosis precluding insertion of the iRF Catheter
- Evidence of active infection within 7 days of the Index Procedure
- Type 1 diabetes mellitus
- Documented history of chronic active inflammatory bowel disorders such as Crohn disease or ulcerative colitis
- eGFR \< 45 mL/min per 1.73 m2
- Brachial circumference ≥ 42 cm
- Any history of cerebrovascular event (e.g., stroke, transient ischemic event, and cerebrovascular accident) within 6 months of patient consent
- Myocardial infarction within 6 months of patient consent
- Heart failure (New York Heart Association \[NYHA\] Class III-IV) at time of consent
- Documented confirmed episode(s) of stable or unstable angina within 6 months of patient consent
- Documented history of persistent or permanent atrial tachyarrhythmia
- Chronic oxygen support or mechanical ventilation other than nocturnal respiratory support for sleep apnea
- Night shift workers
- Chronic regular use (e.g., daily use) of NSAIDs for 6 months or greater. Aspirin therapy is allowed.
- Active implantable medical device (e.g., ICD or CRT-D, neuromodulator/spinal stimulator, baroreflex stimulator)
- Primary pulmonary HTN (\> 60 mmHg pulmonary artery or right ventricular systolic pressure)
- Individual has known pheochromocytoma, Cushing syndrome, primary hyperaldosteronism, coarctation of the aorta, untreated hyperthyroidism, untreated hypothyroidism, or primary hyperparathyroidism. (Note: Treated hyperthyroidism and treated hypothyroidism are permissible.)
- Documented contraindication or allergy to contrast medium not amenable to treatment
- Limited life expectancy of \< 1 year at the discretion of the investigator
- Any known, unresolved history of drug use or alcohol dependency, lacks the ability to comprehend or follow instructions, or for any reason in the opinion of the investigator, would be unlikely or unable to comply with study protocol requirements or whose participation may result in data analysis confounders (e.g., night shift workers)
- Pregnant, nursing, or planning to become pregnant (documented negative pregnancy test result required documented within a maximum of 7 days before procedure for all women of childbearing potential)
- Concurrent enrollment in any other investigational drug or device trial (participation in noninterventional registries is acceptable)
