Abstract
A method of and system for sterilizing the internal surfaces of one or more elongate relatively narrow passages of interest contained in a device of interest, said passages having end openings and being susceptible of sustaining flow therealong by inducing a positive flow of sterilizing gas through each passage of interest in a selected direction. Gas flow through a device of interest is caused by a passive two-chamber device which generates a transient pressure gradient between the ends of the lumens of the device in response to externally imposed variations of pressure. Sterilant gas is provided from outside the two chamber systems.
