Abstract
Devices for providing polymeric layers on the interior surface of body lumens and spaces are disclosed. The devices can include proximal and distal occlusion elements to define the treatment space and an optical emitter to provide light for a photopolymerization procedure. The devices may include a molding member for providing a thick polymeric gel. Alternatively, devices without a molding member may be used to carry out an interfacial polymerization procedure.
