First Claim
Patent Images
1. A method for compressing the volume of a portion of a lung, the method comprising:
- anchoring a first anchor at a first position in the lung;
anchoring a second anchor at a second position in the lung, the first position being distant from the second position;
reducing the distance between the anchored first anchor and the anchored second anchor; and
preventing the reduced distance from substantially increasing.

Abstract
A method and assembly for reducing the volume of a lung. A plurality of anchors are anchored at different positions in the lung. A cord is attached to each of the anchors. The anchors are drawn towards one another via the cords to cause the lung to collapse, thus compressing the tissue in the lung and establishing a reduction in lung volume.

8. A method for compressing the volume of a portion of a lung, the method comprising:
-
anchoring in a portion of a lung an anchor having a cord attached thereto; and
pulling the cord to cause the anchor to pull on the portion of the lung to compress the volume of the portion of the lung. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
pulling the second cord attached to the second anchor to cause the second anchor to pull on the second portion of the lung.

-
10. The method according to claim 9, further comprising cutting the first cord and a second cord to decrease a length of the first cord and the second cord.
-
11. The method according to claim 9, further comprising passing the first cord and the second cord through a self-locking device, wherein the pulling of the first cord and the pulling of the second cord are performed by pulling the first cord and the second cord through the self-locking device.
-
12. The method according to claim 8, wherein the anchor is anchored to a bronchial passageway.
-
13. The method according to claim 9, further comprising connecting the first cord to the second cord.
-
14. The method according to claim 9, wherein the pulling of at least one of the first cord and the second cord causes relative motion between the first anchor and the second anchor in a direction towards each other.
-
15. The method according to claim 9, wherein the first cord is pulled before the second cord is pulled.
-
16. The method according to claim 9, wherein the first cord and the second cord are pulled simultaneously.
-
17. The method according to claim 9, wherein the first cord has a first cord length measured between the anchor and a point of connection, the second cord has a second cord length measured between the anchor and the point of connection, wherein the tensioning of the first cord and the second cord are performed by decreasing the first cord length and the second cord length.
-
18. The method according to claim 8, further comprising located the anchor in the lung by inserting into a bronchial passageway of the lung a bronchoscope having the anchor therein, and then releasing the anchor from the bronchoscope at the portion of the lung to anchor the anchor in the lung.
-
19. The method according to claim 9, wherein the pulling of at least one of the first cord and the second cord causes an anchor length LAD to decrease.
