Abstract
A medical valve has an open mode that permits fluid flow, and a closed mode that prevents fluid flow. The valve has a housing having an inlet and an outlet, and a valving mechanism within the housing to alternatively fluidly connect the inlet and the outlet. The valve is in the open mode when the inlet and outlet fluidly connect. Insertion of a medical implement into the inlet produces a positive fluid displacement at the outlet. In addition, withdrawal of the medical implement as the valve transitions from the open mode to the closed mode produces a substantially neutral fluid displacement at the outlet.
