Abstract

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 one aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit. The system also includes a retention device for securing system elements in position.

Claims

1. A collateral ventilation bypass system comprising:

at least one conduit extending into at least one lung at a predetermined location for removing trapped gases from the at least one lung; and

a fixation device operatively associated with the at least one conduit positioned inside the at least one lung to substantially prevent unnecessary movement of the at least one conduit.

2. The collateral ventilation bypass system according to claim 1, further comprising a sealing device for establishing an airtight seal between the conduit and the lung.

3. The collateral ventilation bypass system according to claim 1, wherein the fixation device comprises at least one balloon operatively associated with the conduit.

4. The collateral ventilation bypass system according to claim 3, wherein the fixation device comprises two balloons operatively associated with the conduit.

5. The collateral ventilation bypass system according to claim 1, wherein the fixation device comprises at least one balloon and at least one retention plate, both operatively associated with the conduits.

6. The collateral ventilation bypass system according to claim 1, wherein the fixation device comprises at least one hinged device operatively associated with the conduit.
