Abstract
Abstract An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
142 words
1 . A method of reducing the size of a lung by collapsing a target section of the lung, the method including the steps of: delivering within a lung air passageway leading to the target section an intra-bronchial one-way valve device having an obstructing member supported on a support structure, the obstructing member being configured to preclude air from being inhaled into the target section, while allowing air to be exhaled from the target section, the one-way valve further comprising at least one anchor member carried by the support structure; and deploying the valve device at a desired location within the air passageway so as to cause the at least one anchor member to move from a delivered state in which the anchor member is spaced from an air passageway wall to an anchored state in which the anchor engages the wall.
Claim 2
Dependent Claim
142 words
1 . A method of reducing the size of a lung by collapsing a target section of the lung, the method including the steps of: delivering within a lung air passageway leading to the target section an intra-bronchial one-way valve device having an obstructing member supported on a support structure, the obstructing member being configured to preclude air from being inhaled into the target section, while allowing air to be exhaled from the target section, the one-way valve further comprising at least one anchor member carried by the support structure; and deploying the valve device at a desired location within the air passageway so as to cause the at least one anchor member to move from a delivered state in which the anchor member is spaced from an air passageway wall to an anchored state in which the anchor engages the wall.
Claim 3
Dependent Claim
30 words
2 . The method of claim 1 , wherein the at least one anchor is releasable from engagement with the air passageway wall for removal of the intra-bronchial device therefrom.
Claim 4
Dependent Claim
31 words
3 . The method of claim 1 , wherein said the step of deploying the valve device comprises removing a restraint configured to hold the anchor members in said delivered state.
Claim 5
Dependent Claim
18 words
4 . The method of claim 1 , further comprising removing the valve device from the desired location.
Claim 6
Dependent Claim
23 words
5 . The method of claim 4 , wherein the step of removing comprises gripping a portion of the valve with intrabronchial forceps.
Claim 7
Dependent Claim
26 words
6 . The method of claim 4 , wherein the step of removing the valve device proximally causes the anchors to release the air passageway walls.
Claim 8
Dependent Claim
120 words
7 . A method of reducing the size of a lung by collapsing a target portion of the lung with a removable device, the method including the steps of: delivering within a lung air passageway leading to the target section an intra-bronchial device comprising a support structure and an obstructing member carried by the support structure, the obstructing member configured to occlude in both directions the air in the passageway, the intra-bronchial device further comprising at least one anchor carried by the support structure, the anchor configured to engage an air passageway wall to resist migration of the obstruction device within the air passageway; deploying the intra-bronchial device in the passageway at a desired location; and removing said intra-bronchial device.
Claim 9
Dependent Claim
120 words
7 . A method of reducing the size of a lung by collapsing a target portion of the lung with a removable device, the method including the steps of: delivering within a lung air passageway leading to the target section an intra-bronchial device comprising a support structure and an obstructing member carried by the support structure, the obstructing member configured to occlude in both directions the air in the passageway, the intra-bronchial device further comprising at least one anchor carried by the support structure, the anchor configured to engage an air passageway wall to resist migration of the obstruction device within the air passageway; deploying the intra-bronchial device in the passageway at a desired location; and removing said intra-bronchial device.
