Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Active Comparator: Valves plus cells
Bronchoscopy Five patients will be selected to receive bone-marrow derived mesenchymal stromal cells delivered bronchoscopically right before insertion of one-way endobronchial valves.
|
Bronchoscopic delivery of one-way valves and bone-marrow derived mesenchymal stromal cells.
|
|
Placebo Comparator: Valves plus saline
Bronchoscopy Five patients will be selected for treatment with one-way endobronchial valves only, with saline injected prior to valve insertion.
|
Bronchoscopic delivery of one-way valves and bone-marrow derived mesenchymal stromal cells.
