5. Years of T2DM ≤ 10 years
3. Diagnosed hypertension with baseline:
1. Office blood pressure of SBP of ≥ 140 mmHg and ≤ 180 mmHg and DBP ≥ 90 mmHg
2. Mean 24-hour ambulatory SBP of ≥ 130 mmHg and ≤ 170 mmHg with ≥ 75% valid readings
3. On stable oral anti-hypertension drug regimen consisting of up to a maximum of three drugs
4. BMI between 27.5 and 40 kg/m2
5. C-peptide testing: non-fasting random or stimulated C-peptide ≥ 2 ng/mL (660 pmol/L)
6. Vessel diameter of 3 mm to 6.5 mm inclusively with a minimum arterial treatable length of 20 mm in one or more of the following arteries:
* Renal
* Hepatic
Exclusion Criteria:
1. T1DM or poorly controlled T2DM (defined as HbA1c \> 9.0% or use insulin as medication to control glucose level).
2. Office diastolic blood pressure \< 90 mmHg.
3. Current use of \> 3 hypertension medications.
4. Currently on beta blockers or alpha blockers.
5. One or more documented hyperglycemia episodes requiring hospitalization in the 180-day prior to screening date.
6. Prior evidence of hypoglycemia unawareness or serious hypoglycemia with loss of consciousness or confusion sufficient to prevent self-treatment in last 6 months.
7. BMI \> 40 kg/m2.
8. Diagnosed proliferative retinopathy or evidence of peripheral neuropathy.
9. Lack of appropriate treatment site or anatomy precluding the intervention of the target arteries (renal and hepatic artery).
10. History of prior renal or hepatic artery intervention including balloon angioplasty, stenting, etc.
11. Arterial stenosis \>50% of the normal diameter segment (diameter stenosis, compared to the angiographically normal proximal or distal segment).
12. Any abnormality or disease in one or more of the target arteries that, per the physician assessment, precludes the safe insertion of the guiding catheter (including, but not limited to, artery aneurysm, excessive tortuosity, calcification).
13. Occlusive peripheral vascular disease that would preclude percutaneous femoral access for the procedure.
14. Known or suspected secondary hypertension, such as Cushing's disease or Cushing's Syndrome, hyperaldosteronism, pheochromocytoma, thyroid and parathyroid abnormalities, history of pre-eclampsia, onset of hypertension prior to the age of 18.
15. Use of nonsteroidal anti-inflammatory drugs (NSAIDs) for two or more days per week over the month prior to enrollment.
