A dual lumen syringe (10) includes a body (12) having a pair of elongate cavities or lumens (14, 16) formed therein. A directional valve (24, 32) is associated with each lumen. The valve is alternated between the first position wherein the lumen is communicably connected to a fluid inlet (28, 36) and a second position wherein the lumen is connected with a fluid outlet (26, 34). There are a pair of elongate plungers (102, 108), which are fixedly interconnected by a handle (114). Each plunger is received and longitudinally slidable in a reciprocating manner through a respective lumen. The valves are switched to a first position wherein the lumens are interconnected with the fluid inlets and the plunger is retracted to aspirate fluids through the respective inlets and into the lumens. The valves are then switched to a second position to communicably interconnect the lumens with the outlets. The plungers are then simultaneously driven inwardly through the respective lumens to drive the fluids simultaneously through the outlets to a dispensing tip (50) permanently connected to the body and in communication with the outlets.
