Removable anchored lung volume reduction device and methods

A method of treating a portion of 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 the 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;
• deploying the anchoring device such that the anchoring device engages the air passageway and the obstructing member,
• removing the anchoring device;
• and
• removing the obstructing member.

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.

• 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.
