Improvement of sleep quality in emphysema patients is desirable. Yet, there are no data of patients treated with RePneu coils. This monocenter prospective study investigates the effect on sleep quality of RePneu coils for reduction of dynamic hyperinflation in advanced disease stages of pulmonary emphysema. Patient's sleep will be studied in three Polysomnography measurement nights, one prior to Coil Treatment, one six months after, and one twelve month after. Primary objective is to investigate differences in sleep quality 6 and 12 months after Coil Treatment. Further endpoints are changes in daily activity and sleep (actigraphy), 6MWT, lung function parameters, and questionnaires (SGRQ, mMRC dyspnoe scale).

Sleep efficiency, measured in baseline and 6 and 12 month after coil treatment.
Sleep Efficiency is evaluated by the ratio of WASO (Time "wake after sleep onset") to Sleep Period Time (SPT).
Time frame: 3 times in one year
Quality of life Questionnaire
The St. George Respiratory Questionnaire (SGRQ) is designed to capture the health related quality of life.
Time frame: 3 times in one year
