Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is exploratory in nature and will evaluate procedural and long-term safety of multi-organ denervation (MDN) and provide preliminary efficacy data in two parallel single arm cohorts:

* Gemini Pilot Off Med: MDN for Hypertension Off Anti-hypertensive Meds and,
* Gemini Pilot On Med: MDN for Hypertension and High Cardiovascular Risk On Anti-hypertensive Meds

There is no pre-specified primary endpoint; however, the data will be used for hypothesis generation to be evaluated and confirmed in subsequent clinical investigation(s).
