Brief Summary
The purpose of the SPYRAL GEMINI Pilot Study is to evaluate that multi-organ denervation with the Gemini System is safe and provide evidence of blood pressure reduction when studied in an uncontrolled hypertensive population with and without high cardiovascular risk.

EXPERIMENTALInterventions
After angiography according to standard procedures, subjects are treated with renal denervation followed by hepatic denervation.
Eligibility Criteria
