Global Pilot Study of rEnal and Hepatic coMbINed denervatIon in Subjects With Uncontrolled Hypertension With and Without High Cardiovascular Risk
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.
