Abstract

See full text

An apparatus and method for achieving low temperature vapor sterilization of objects which may involve objects having a lumen. Following evacuation of the sterilization chamber and the introduction of a vaporous or gaseous sterilant, the volume of the chamber is changed by actuation of a movable boundary in the chamber to increase and decrease the pressure in the chamber thus driving the sterilant into and out of such lumens.
