Removable anchored lung volume reduction device and methods
First Claim
1. A method of treating a lung, the method including the steps of:
- providing an intra-bronchial device comprising an obstructing member which is so dimensioned when deployed in an air passageway communicating with a portion of the lung to preclude air from being inhaled, and a barbed anchoring device that anchors the obstructing member in the air passageway by engaging the obstructing member and the wall of the air passageway when the anchoring device is deployed;
placing the obstructing member in the air passageway;
separately placing the anchoring device in the air passageway; and
deploying the anchoring device such that the anchoring device engages the air passageway and the obstructing member.

Abstract
An intra-bronchial device may be placed in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member that prevents air from being inhaled into the lung portion to collapse the lung portion, and an anchoring device that anchors the obstructing member in the air passageway by engaging the obstructing member and the air passageway wall. The anchoring device may frictionally engage the obstructing member and the air passageway, or engage both by piercing. The engagement provided by the anchoring device may be releasable for removal of the obstructing member. The anchoring device may be balloon expandable from a first shape to a second shape that engages the obstructing member and the air passageway. The obstructing member may be a one-way valve.

9. A method of treating a lung, the method comprising:
-
providing an intra-bronchial device comprising an obstructing member which is so dimensioned when deployed in an air passageway communicating with a portion of the lung to substantially preclude air from being inhaled, and an anchoring device that anchors the obstructing member in the air passageway by engaging the obstructing member and the wall of the air passageway when the anchoring device is deployed;
placing the obstructing member in the air passageway;
placing the anchoring device in the air passageway, the entire anchoring device being spaced from the obstructing member; and
moving the anchoring device along the air passageway and into engagement with the obstructing member, and then deploying the anchoring device. - View Dependent Claims (10)

13. A method of treating a lung, the method comprising:
-
providing an intra-bronchial device comprising an obstructing member which is so dimensioned when deployed in an air passageway communicating with a portion of the lung to substantially preclude air from being inhaled, and a barbed anchoring device that anchors the obstructing member in the air passageway;
placing the obstructing member in the air passageway;
separately placing the anchoring device in the air passageway, the entire anchoring device being spaced from the obstructing member; and
deploying the anchoring device such that the barbs pierce and pass through the obstructing member when the anchoring device and obstructing member are within the air passageway. - View Dependent Claims (14)
