A Study of the Use of Chartis System to Optimize Subject Selection for Endobronchial Lung Volume Reduction (ELVR)

A Study of the Use of Chartis System to Optimize Subject Selection for Endobronchial Lung Volume Reduction (ELVR) in Subjects With Heterogeneous Emphysema

Use of the Chartis® Assessment System prior to EBV Treatment

This is a multi-center study which will enroll up to 120 patients. Subjects will undergo a Chartis Assessment prior to EBV treatment. The Chartis assessment will determine the presence or absence of collateral ventilation, a potential determining factor in the success of EBV therapy. This study is not randomized; all subjects are eligible to receive EBV Treatment, regardless of Chartis Assessment outcome. Follow-up data will only be collected on those patients that meet the Chartis inclusion criteria.

Inclusion Criteria:

• Heterogeneous emphysema
• Able to obtain a Chartis value during Assessment

Exclusion Criteria:

• Any co-existing major medical problems that would not make it possible for the subject to tolerate a bronchoscopic procedure.
