Unilateral Bronchoscopic Thermal Vapor Ablation for Lung Volume Reduction

Detailed Description:

All subjects meeting the eligibility criteria and who provide written informed consent will be enrolled. Up to 3 segments in either the right or left upper lobe will be treated with a vapor dose of 10 calories per gram of lung tissue (10 cal/g). Targeted lobe for treatment will be based on lobar disease severity.
