Abstract
Embodiments of luer-type needle-free valve devices are disclosed. One of the novel aspects of the invention is its ability to transform from an open state to a closed state. The open position eliminates the potential for a differential pressure to exist between the volume connected to the inlet and outlet of the valve fitting. The closed position enables the device to maintain a differential pressure between the volume connected to the inlet and outlet of the valve fitting. The invention is useful in manufacturing sterile medical devices by allowing all surfaces to communicate with the sterilizing agent when the valve is in an open configuration when it is in a closed position.
