Abstract
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 patient's 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
1 . A collateral ventilation bypass trap system comprising: a containment vessel for collecting discharge from one or more lungs of a patient; at least one conduit having a first end connected to the containment vessel and a second end passing through the thoracic wall and lung of a patient at a predetermined site, thereby establishing fluid communication between the containment vessel and the inner volume of the lung; and a sealing device for establishing a fluid tight seal between the at least one conduit and the thoracic wall and between the at least one conduit and the lung.
Claim 2
Dependent Claim
99 words
1 . A collateral ventilation bypass trap system comprising: a containment vessel for collecting discharge from one or more lungs of a patient; at least one conduit having a first end connected to the containment vessel and a second end passing through the thoracic wall and lung of a patient at a predetermined site, thereby establishing fluid communication between the containment vessel and the inner volume of the lung; and a sealing device for establishing a fluid tight seal between the at least one conduit and the thoracic wall and between the at least one conduit and the lung.
Claim 3
Dependent Claim
112 words
2 . A collateral ventilation bypass trap system comprising: a containment vessel for collecting discharge from one or more lungs of a patient; a filter/one-way valve connected to the containment vessel; at least one conduit having a first end connected to the containment vessel through the filter one-way valve and a second end passing through the thoracic wall and lung of a patient at a predetermined site, thereby establishing fluid communication between the containment vessel and the inner volume of the lung; and a sealing device for establishing a fluid tight seal between the at least one conduit and the thoracic wall and between the at least one conduit and the lung.
Claim 4
Dependent Claim
112 words
2 . A collateral ventilation bypass trap system comprising: a containment vessel for collecting discharge from one or more lungs of a patient; a filter/one-way valve connected to the containment vessel; at least one conduit having a first end connected to the containment vessel through the filter one-way valve and a second end passing through the thoracic wall and lung of a patient at a predetermined site, thereby establishing fluid communication between the containment vessel and the inner volume of the lung; and a sealing device for establishing a fluid tight seal between the at least one conduit and the thoracic wall and between the at least one conduit and the lung.
Claim 5
Dependent Claim
112 words
3 . A method for increasing the expiratory flow from a diseased lung, the method comprising: creating an anastomotic opening extending from the thoracic wall and into the inner volume of the lung at a site determined to have a high degree of collateral ventilation; establishing a fluid communication link between the inner volume of the lung at the site determined to have a high degree of collateral ventilation and a containment vessel through a conduit extending from the containment vessel to the lung through the anastomotic opening such that air in the lung flows into the containment vessel; and establishing a fluid tight seal between the anastomotic opening and the conduit.
Claim 6
Dependent Claim
112 words
