A medical valve has a translating member that enlarges the volume of the interior of the valve when the valve is in an open mode (permitting fluid flow), and decreases the volume of the interior when the valve is in a closed mode (preventing fluid flow). This varying volume should substantially eliminate drawback into the valve. To that end, the valve includes a housing having an inlet and an outlet, and a fluid channel extending between the inlet and the outlet. The fluid channel includes a variable volume region. The valve further includes the above noted translating member, which is secured to the housing and at least partly bounds the variable volume region. The translating member has at least a portion that moves distally when the valve transitions from the closed mode to the open mode. The distal movement of the translating member enlarges the volume on the variable volume region.
