Brief Summary:
Use of the Chartis® Assessment System prior to EBV Treatment

Condition or disease Intervention/treatment Phase
Emphysema Device: Chartis System Device: Endobronchial Valve (EBV) Treatment Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Chartis System-EBV Treatment
Subjects with heterogeneous emphysema, had their collateral ventilation status in the target treatment lobe assessed using the Chartis System (CV- or CV+) and underwent endobronchial lung volume reduction (ELVR) with endobronchial valves (EBV).
Device: Chartis System
The Chartis System provides a value that represents the quantification of the average resistance to airflow through collateral airways.

Device: Endobronchial Valve (EBV) Treatment
The endobronchial valve is designed to induce target lobe volume reduction.

Primary Outcome Measures :
  1. Lung Volume Change [ Time Frame: 30 Days ]
