Abstract: Methods and devices for at least partially occluding an airway of a lung is disclosed. The method includes deploying a catheter into the airway such that a balloon at a distal end of the catheter is positioned proximate a tissue wall that defines the airway, and inflating the balloon to cause pressure to be applied on a portion of the tissue wall. The method may also include deflating the balloon to cause the portion of the tissue wall to be drawn radially inward to at least partially occlude the airway.
