Clinical Trial Summary

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.

Description:

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.
