Circumferential Ultrasonic Renal Denervation Targeting Main Renal Arteries and Branches

Year: 2026

Type: article

Abstract: This study assessed the feasibility and safety of ultrasound renal denervation (uRDN) targeting both main and branch renal arteries to treat uncontrolled hypertension. A circumferential uRDN system was evaluated in a porcine model (n = 6) and a first-in-human study (n = 5). Endpoints included the incidence of device-related adverse events and changes in blood pressure. Preclinical studies revealed a favorable safety profile and >97% reduction in renal norepinephrine levels. In the human study, all procedures were technically successful without device-related adverse events. At 2 and 6 months, 24-hour ambulatory systolic/diastolic blood pressure decreased by 8.8 (95% CI: 0.98-16.62)/4.6 (95% CI: -1.83 to 11.03) mm Hg and 16 (95% CI: 1.18-30.82)/8 (95% CI: 0.76-15.24) mm Hg , respectively. These preliminary findings support the feasibility and safety of this circumferential uRDN approach for uncontrolled hypertension.
