Abstract
A medical valve includes a housing having an interior forming an inlet and an outlet. A longitudinally movable member is secured within the interior of the housing. External to the movable member and within the interior is a fluid path. Movement of the movable member controls fluid flow between the inlet and the outlet via the fluid path. The outlet produces no greater than a negligible drawback or positive push during withdrawal of a nozzle.
