| Research Abstract |
Chronic obstructive pulmonary disease is characterized by the over inflation and loss of elastic recoil of the lung. We designed an elastic mesh to cover the lung to restore the elastic recoil. We clarified the lung volume reduction effect of the mesh by the the 3-D CT scan after the implantation. The mechanical properties were measured before and after the mesh implantation. The static and the dynamic pressure-volume loops are determined. A rightward shift of the pressure volume loop was observed, which shows increasing of the lung elastic recoil. The elastic energy stored during the inspiration showed 20% of augmentation. The elastic mesh coverage to the lung proved to increase the elasticity of the lung.
