Pulmonary Artery DenerVation Clinical Study Using the Gradient Denervation System in Heart Failure Patients With Pulmonary Hypertension Group 2 (PreVail-PH2 OUS Study)
The Gradient Denervation System delivers ultrasound ablation to planned locations in the pulmonary artery to down-regulate the sympathetic nervous drive. The system includes a sterile, single-use catheter that is designed to centrally position the transducer within the arterial target zone for consistency of ablation.
