The objective of the study is to evaluate the safety of multi-organ denervation using the Integrated Radio Frequency (iRF) Denervation System. and to understand any potential improvement in hypertension and glycemic control.
This study is a prospective, single-arm, multi-center, sham contollred trial to evaluate the initial safety and performance of multi-organ denervation for the treatment of hypertension and type 2 diabetes.

Myocardial infarction within 6 months of Index Procedure
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 prior to Index Procedure
Documented history of persistent or permanent atrial tachyarrhythmia

Known Primary pulmonary hypertension (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.)
A history of bariatric surgery, baroreflex activation therapy, or liver transplant, or these procedures are planned in the 365 days following Index Procedure
Previous hepatobiliary surgery/intervention that in the opinion of the investigator could preclude the ability to perform denervation of the CHA

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
Pregnant, nursing, or planning to become pregnant (documented negative pregnancy test result required documented within a maximum of 7 days before Index Procedure for all women of childbearing potential)

Subjects will be blinded during the procedure by a combination of the conscious sedation, sensory isolation and sedation and lack of familiarity of the procedural details and duration (i.e., subjects will not know the difference between the renal angiography procedure alone and the renal angiography and denervation procedure).
| Control Procedure | Other | If assigned to the control group, subjects will remain blinded and recieve angiography of the target arteries prior to sheath removal. |
