Clinical Trial Summary

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

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
