Patients with heterogenous emphysema benefits from endoscopic lung volume reduction. Until now the technique is limited to one lobe. In case of collateral ventilation patients show no improvement. Between upper and middle lobe exists the highest collateral flow. The trial examine the hypothesis, that sequential ELVR help especially those patients, which have no benefit after lobar exclusion.

Condition Intervention Phase

Intervention Details:
    Device: Zephyr endobronchial valve
    Endobronchial valve system to redirect the airflow within the bronchial system
