Abstract

See full text

A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet and an outlet, a rigid member movably mounted within the housing, and a resilient member with a sealing portion. The housing also has at least one relief zone that is in fluid communication with the outlet when the valve is in the closed mode. The rigid member may have a proximal end, a distal end, and a flow channel. The relief zone may be radially outward from the sealing portion. The sealing portion may seal the valve and prevent fluid from passing through the valve when in the closed mode.
