International First-in-Human Study of the EnligHTN Generation 2 System in Patients With Drug-resistant Uncontrolled Hypertension (EnligHTN III)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this First-in-Human Clinical investigation is to evaluate the safety and performance of the St. Jude Medical EnligHTN™ Generation 2 Renal Denervation System for the treatment of patients with drug-resistant uncontrolled hypertension.
