Abstract

The invention provides devices and systems for treating lungs. One aspect of the invention provides a lung device with an expandable member having an open lumen formed therethrough, the expandable (e.g., inflatable and compliant) member having an expanded diameter adapted to contact a circumferential wall portion of a lung air passageway. The device may also include a plug adapted to close the open lumen and a coupler adapted to couple the plug and the expandable member. Another aspect of the invention provides a lung device and delivery system including: an expandable member having an open lumen formed therethrough, the expandable member having an expanded diameter adapted to fit within a lung air passageway; and a delivery catheter adapted to deliver the expandable member to a lung air passageway, the delivery catheter having a coupler adapted to couple the catheter to the expandable member.

CROSS-REFERENCE

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 580,565, filed Jun. 16, 2004, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION

[0002] The primary role of the lung is to perform the function of breathing which assists in the intake of oxygen and removal of carbon dioxide from the body. The oxygen in air is inhaled through the mouth and trachea to the main bronchi. The bronchi divide at the end of the trachea into the left and right main bronchi and these respectively divide into bronchial branches, which “feed” the three lobes of the lung on the right and two on the left. These bronchi continue to subdivide into bronchioles (smaller bronchi), over twenty three times in total. The over 100,000 bronchioles get smaller in diameter and ultimately terminate in over 300 million air sacs, called alveoli. The alveoli, which are clustered like grapes, are approximately 0.3 mm in diameter and provide a huge ...
