## Abstract

Methods of treating COPD, including bronchoscopically positioning a lung anchor in lung tissue, positioning an outer implant member in pleural space proximate the lung anchor, and coupling the lung anchor to the outer implant member and thereby compressing lung tissue.

## Claims

### Claim 1

A method of treating COPD, comprising:
bronchoscopically positioning a lung anchor in lung tissue;
positioning an outer implant member in pleural space proximate the lung anchor; and
coupling the lung anchor to the outer implant member and thereby compressing lung tissue.

### Claim 2 (depends on 1)

The method of claim 1, wherein coupling the lung anchor to the outer implant member comprises magnetically coupling the lung anchor to the outer implant member.

### Claim 3 (depends on 1)

The method of claim 1, wherein bronchoscopically positioning a lung anchor in lung tissue comprises bronchoscopically positioning a lung anchor with a tether extending proximally from the lung anchor.

### Claim 4 (depends on 3)

The method of claim 3, wherein the lung anchor is a first lung anchor, the method further comprising bronchoscopically delivering a second anchor in the lung tissue, proximal to the first lung anchor, where the tether line extends from the proximal anchor.

### Claim 5 (depends on 4)

The method of claim 4, further comprising securing the second anchor in the lung tissue, and wherein the coupling step occurs before securing the second anchor in the lung tissue.

### Claim 6 (depends on 5)

The method of claim 5, further comprising tensioning the tether line and securing the tether line to the second anchor, the tensioning step occurring after the coupling step.

### Claim 7 (depends on 4)

The method of claim 4, further comprising securing the second anchor in the lung tissue, and wherein the coupling step occurs after securing the second anchor in the lung tissue.

### Claim 8 (depends on 7)

The method of claim 7, further comprising tensioning the tether line and securing the tether line to the second anchor, the tensioning step occurring before the coupling step

### Claim 9 (depends on 1)

The method of claim 1 wherein positioning an outer implant member in pleural space proximate the lung anchor comprises advancing a pleural delivery catheter into the pleural space.

### Claim 10 (depends on 9)

The method of claim 9, wherein advancing a pleural delivery catheter into the pleural space comprises introducing the pleural delivery catheter via a thoracostomy.

### Claim 11 (depends on 9)

The method of claim 9, wherein the coupling step comprises moving at least a portion of the outer implant member closer to the lung anchor.

### Claim 12 (depends on 11)

The method of claim 11, wherein moving at least a portion of the outer implant member comprises deflecting the pleural delivery catheter.

### Claim 13 (depends on 1)

The method of claim 1, wherein the coupling step comprises magnetically coupling the lung anchor to the outer implant member from a magnetic attraction between magnetic coupling elements provided in the lung anchor and outer implant member.
