Abstract
Embodiments of passive vent valve devices are disclosed. One of the novel aspects of the invention is its ability to transform from a packaging configuration to a use configuration. The packaging configuration allows sterilization gases to penetrate into the device through standard valve openings as well as through vented mesh openings. Passage of gas into the device, in turn, provides a means of sterilizing all surface areas in the device. Alternatively, when the valve is placed in a use configuration, the passage of gas through the vented mesh is inhibited providing a sealed environment that functions as a valve. The invention is useful in manufacturing sterile medical devices by allowing all surfaces to communicate with the sterilizing agent when the valve is in a packaging configuration or when it is in a use configuration.
