Cinenses Lung Volume Reduction Reverser System First-in-man Study Treating Patients With Severe Emphysema
Cinenses Lung Volume Reduction Reverser System First-in-man Study Treating Patients With Severe Emphysema
The study is designed as a prospective, nonrandomized, exploratory, single center,
 first-in-man study. The objective of this study is to evaluate its safety and feasibility of
 the CinensesTM Lung Volume Reduction Reverser System in patients with severe emphysema. The
 study will also collect clinical data up to 6-month follow-up to explore its safety and
 effectiveness.
