ABSTRACT:
A medical valve has an open mode that permits fluid flow, and a closed mode that prevents fluid flow. Among other things, the medical valve includes a housing forming an interior having a fluid chamber, and a valve mechanism within the interior. The valve mechanism has a movable member that includes a needle (e.g., a hypetube). The needle may extend into the fluid chamber when the valve is in the open mode.
