Patent ID: 7887585

Claim:
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, the delivery catheter further comprising a retractable sheath that is retractable in relation to the obstruction device; 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; the occlusion device further being configured to expand and contract during expansion and contraction of surrounding lung tissue during a respiration cycle; the occlusion device further comprising a central connector rod; and a removal device comprising gripping elements configured to grip the central connector rod for removal of the occlusion device from the airway.
