LUNG REDUCTION SYSTEM
First Claim
1. A method for reducing the volume of a hyperinflated portion of a lung of a patient comprising:
- determining a site of hyprinflation in a patient'"'"'s lung;
allowing air from the hyperinflated portion of the lung to vent through a device to the ambient environment; and
wherein the allowing step includes;
a. positioning a sealing device to establish an airtight seal between at least one first implantable member and the lung; and
b. positioning the at least the one first implantable member in fluid communication, at the predetermined site, within a lung of a patient, the at least one implantable member passing through a lung via a passage created therethrough; and
c. positioning a second member connected to the at least one first implantable member, the second member being secured external of the lung.

Abstract
A long term oxygen therapy system having an oxygen supply directly linked with a patient'"'"'s lung or lungs may be utilized to more efficiently treat hypoxia caused by chronic obstructive pulmonary disease such as emphysema and chronic bronchitis. The system includes an oxygen source, one or more valves and fluid carrying conduits. The fluid carrying conduits link the oxygen source to diseased sites within the patients lungs. A collateral ventilation bypass trap system directly linked with a patient'"'"'s lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating another aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit. In various embodiments, the system may be intrathoracic, extrathoracic or a combination thereof. A pulmonary decompression device may also be utilized to remove trapped air in the lung or lungs, thereby reducing the volume of diseased lung tissue. A lung reduction device may passively decompress the lung or lungs. In order for the system to be effective, an airtight seal between the parietal and visceral pleurae is required. Chemical pleurodesis is utilized for creating the seal.
