Brief Summary:
This study will look at outcomes between Endobronchial Coil Treatment and Control groups in patients with severe heterogeneous and or homogeneous emphysema.

Condition or disease Intervention/treatment Phase
Emphysema Device: Endobronchial Coils Not Applicable

Detailed Description:
This will be a prospective, multicenter, randomized, controlled study comparing outcomes between the Endobronchial Coil and Control Groups. Subjects will be block randomized in a Treatment to Control ratio of 2:1. The randomization will be stratified by site and homogeneous versus heterogeneous emphysema, to support a balance of patients with differing heterogeneity in both the Treatment and Control Groups
