The combined data from 3 studies outside the Unites States investigating the Lung Volume Reduction Coil system (RePneu LVRC) showed statistically significant improvements in pulmonary function, exercise capacity and quality of life at both 6-Months and 12-Months post treatment. 24 months post treatment the improved pulmonary function and exercise capacity are slightly decreasing. Retreating the patient with the LVR coil system in other parts of the lung could potentially lead to new improvements in lung function, dyspnea, exercise capacity and quality of life and may reduce the rate of decline.
