Abstract
A method and system for increasing the flow resistance of collateral pathways in the lung by employing aspiration to establish an artificial convective flow current between compartments in the lung in order to entrain and deliver a clogging agent preferentially to the collateral pathways. The method may sometimes be performed after lung has been assessed for the presence of collateral pathways.
