Abstract
Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves incorporating a piston comprising slit along an upper piston section for accommodating fluid flow. The slit is closed by the relative geometry of the piston and the valve housing, which acts to terminate fluid flow from between the inlet and outlet of the valve assembly.
