Document Type and Number:
WIPO Patent Application WO2002022072
Kind Code:
A3
Abstract:
Achieving lung volume reduction includes occluding a lumen of a bronchial tube of a lung to prevent air flow to at least a region of the lung. Bronchial occluders such as polymerizable materials and mechanical devices, such as sutures, staples, clips, clamps, foam, balloons, umbrellas and ball bearings are provided for occluding a bronchial tube. Methods include mixing thickeners or foaming agents with polymerizable compositions and introducing the mixture into a lumen of a bronchial tube. Mechanisms for mixing components and delivering the mixture to a lumen of a bronchial tube are also provided.
