Abstract: A method of treating snoring, includes injecting least one of a monomer composition, a polymer solution and a microparticle solution into a patient's soft palate, optionally with a least one of an additional medicament, bioactive agent, sclerotic agent or stiffening agent. The injected composition, if not already polymerized prior to injection, is allowed to polymerize to form a polymer within the soft palate, thereby stiffening the soft palate, rendering it resistant to palatal flutter.

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.
