Bronchoscopic lung volume reduction (BLVR) using endobronchial coil treatment is a widely studied therapeutic option in patients with end-stage chronic obstructive pulmonary disease (COPD) and pulmonary emphysema. However, patient responses were inconsistent, and, from 2020, production discontinuation rendered the treatment unavailable. In the meantime, a next-generation lung tensioning coil (FreeFlow Coil 4; FreeFlow Medical, Inc., Fremont, CA, USA) has been developed by the inventor of the lung volume reduction coil implant technology. This case study presents the first documented successful BLVR using FreeFlow Coils 4.
