Abstract
Abstract An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and re-collapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by re-collapsing the device and pulling the device proximally through a catheter.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
83 words
1 . A one-way obstruction device configured to permit fluid flow in an expiratory direction through an air passageway in a lung while precluding inhalation air flow through the passageway, the device comprising: a frame defining a generally cylindrical portion, the frame being collapsible for advancement through a lumen into the air passageway; a resilient member at least partially enclosing the frame and configured to contact an inner wall of the passageway to obstruct airflow through the air passageway in an inspiratory direction.
Claim 2
Dependent Claim
83 words
1 . A one-way obstruction device configured to permit fluid flow in an expiratory direction through an air passageway in a lung while precluding inhalation air flow through the passageway, the device comprising: a frame defining a generally cylindrical portion, the frame being collapsible for advancement through a lumen into the air passageway; a resilient member at least partially enclosing the frame and configured to contact an inner wall of the passageway to obstruct airflow through the air passageway in an inspiratory direction.
Claim 3
Dependent Claim
16 words
2 . The obstruction device of claim 1 , wherein frame comprises a serpentine reinforcement rib.
Claim 4
Dependent Claim
26 words
3 . The obstruction device of claim 1 , wherein the valve is configured to allow expiratory air to flow through a center of the frame.
Claim 5
Dependent Claim
17 words
4 . The obstruction device of claim 1 , wherein the frame comprises a resilient self-expanding structure.
Claim 6
Dependent Claim
17 words
5 . The obstruction device of claim 4 , wherein the frame is made of nickel titanium.
Claim 7
Dependent Claim
17 words
6 . The obstruction device of claim 4 , wherein the frame is made of stainless steel.
Claim 8
Dependent Claim
33 words
7 . The obstruction device of any of claim 1 , wherein the frame is configured to seal against an air passageway sufficiently to preclude airflow between the device and the passageway wall.
Claim 9
Dependent Claim
20 words
8 . The one-way obstruction device of claim 1 , wherein the resilient member comprises a membrane overlying the frame.
Claim 10
Dependent Claim
19 words
9 . The one-way obstruction device of claim 1 , wherein the resilient member substantially entirely encloses the frame.
Claim 11
Dependent Claim
90 words
10 . A method of treating a lung comprising: compressing an obstruction device comprising a frame defining a generally cylindrical portion and having a resilient member at least partially enclosing the frame, and delivering the obstruction device through a conduit and into an air passageway of a lung and deploying the obstruction device in the airway such that the obstruction device contacts an inner wall of the passageway and obstructs airflow through the air passageway in an inspiratory direction, while allowing airflow through the air passageway in an expiratory direction.
Claim 12
Dependent Claim
90 words
10 . A method of treating a lung comprising: compressing an obstruction device comprising a frame defining a generally cylindrical portion and having a resilient member at least partially enclosing the frame, and delivering the obstruction device through a conduit and into an air passageway of a lung and deploying the obstruction device in the airway such that the obstruction device contacts an inner wall of the passageway and obstructs airflow through the air passageway in an inspiratory direction, while allowing airflow through the air passageway in an expiratory direction.
Claim 13
Dependent Claim
31 words
11 . The method of claim 10 , wherein delivering the obstruction device through the conduit comprises advancing the obstruction device, in a compressed state, through a lumen of a catheter.
Claim 14
Dependent Claim
27 words
12 . The method of claim 10 , further comprising allowing a portion of the lung distal to the deployed obstruction device to be reduced in volume.
Claim 15
Dependent Claim
29 words
13 . The method of claim 10 , wherein allowing airflow through the air passageway in an expiratory direction comprises allowing airflow through a central portion of the frame.
Claim 16
Dependent Claim
25 words
14 . The method of claim 10 , wherein deploying the obstruction device comprises releasing the obstruction device from a distal end of a catheter.
Claim 17
Dependent Claim
32 words
15 . The method of claim 10 , wherein deploying the obstruction device comprises providing a resilient self-expanding frame and allowing the obstruction device to expand to contact the air passageway walls.
