Bronchoscopic Thermal Vapor Ablation (BTVA) for Lung Volume Reduction (BTVA)

February 21, 2012 updated by: Uptake Medical Corp

Evaluation Study of Unilateral Bronchoscopic Thermal Vapor Ablation (BTVA) in Patients With Heterogeneous Emphysema and Upper Lobe Predominance

To establish and confirm the safety and clinical utility of BTVA applied unilaterally for lung volume reduction in patients with upper lobe predominate heterogeneous severe emphysema.

Intervention / Treatment

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.
