Abstract
A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the valve has a housing with an inlet and an outlet, and actuator moveable distally within the housing. The medical valve also has a resilient member with an aperture. The distal movement of the actuator opens the aperture within the resilient member, thereby transitioning the medical valve from the open to the closed mode.
