Abstract
Devices, compositions, and methods for achieving non-surgical lung volume reduction (e.g., bronchoscopic lung volume reduction (BLVR)) are described. BLVR can be carried out by collapsing a region of the lung, adhering one portion of the collapsed region to another, and promoting fibrosis in or around the adherent tissue.
Claims32
A method of reducing lung volume in a patient, the method comprising:
- (a) advancing a bronchoscope into a region of the lung targeted for reduction;
- and
- (b) introducing biological or biochemical material into the targeted region through the bronchoscope to reduce the volume of the targeted region by inducing collapse of the targeted region;
- promoting adhesion between one portion of the collapsed lung and another;
- and promoting fibrosis in or around the collapsed region of the lung.

- (a) advancing a bronchoscope into a region of the lung targeted for reduction;
- and
- (b) introducing biological or biochemical material into the targeted region through the bronchoscope to reduce the volume of the targeted region,
- wherein the biological or biochemical material introduced through the bronchoscope induces collapse of the targeted region;
- and promotes adhesion between one collapsed portion of the lung and another.

A non-surgical method for performing lung volume reduction, the method comprising:
- (a) collapsing a region of the lung;
- (b) adhering one portion of the collapsed region to another;
- and
- (c) promoting fibrosis in or around the collapsed region of the lung, wherein promoting fibrosis in or around the collapsed region of the lung is achieved by administering a polypeptide growth factor.
