Pulmonary Hypertension
Conditions
Brief summary
Characterize the impact of pulmonary artery denervation on the quality of life in Heart Failure Patients with Group 2 Pulmonary Hypertension
Detailed description
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.
