Evaluation of Physiologic Parameters to Study the Mechanism of Action of the Lung Volume Reduction Coil in Subjects With Homogeneous Emphysema

This study has been completed.

The PneumRx Lung Volume Reduction Coil (LVRC) has been shown to effectively improve quality of life, exercise capacity, and static lung volumes, in patients with emphysema. The mechanism of action for these effects is believed to be related to the restoration of elastic recoil to lung parenchyma that has been damaged by emphysema. The objective of this study is to evaluate several physiologic parameters which should provide measures directly related to the mechanism of action by which the coils produce these outcomes.

Primary Outcome Measures:
  • 6 minute walk test (6MWT) [ Time Frame: 6 months ]
    The primary effectiveness endpoint will be the improvement in the 6 minute walk test (6MWT) from Baseline compared to Follow-Up.

Secondary Outcome Measures:
  • Adverse Events [ Time Frame: 6 months ]
    The safety objective of this study is to identify the adverse effects attributed to device.
