## Abstract

Systems and devices for minimally invasively treating an air leak in a lung comprise the steps of detecting an air leak in a lung; locating an airway in fluid communication with the air leak, introducing a bronchoscope into a patient's airway to a position adjacent the target section and occluding an airway upstream of the air leak for a period of time. The airway occlusion device is preferably removed after the air leak has substantially permanently healed. The occluding device may be a one-way valve. The occluding device may also comprise strut members and anchors that penetrate an airway wall.

## Claims

### Claim 1

A system for use in treating an air leak in a lung, the system comprising:
a balloon catheter configured to occlude an airway and to simultaneously measure a diameter of the airway;
a delivery catheter configured to deliver an obstruction device into an airway of the lung;
at least one occlusion device adapted to occlude airflow in an inspiratory direction while allowing fluid to flow in an expiratory direction;
the occlusion device being configured such that fluid flow in the expiratory direction passes between an airway wall and a portion of the occlusion device; and
the occlusion device further being configured to expand and contract during expansion and contraction of surrounding lung tissue during a respiration cycle.
