Patent Number: 6,309,372

Title: Integrated mixing and dispensing apparatus

Abstract: A syringe apparatus for mixing and delivering a two-part material has (i) a syringe barrel and a plunger. The apparatus also has a paddle slidably coupled to the plunger. A distal insertion end of the plunger has a slot therein. A proximal end of the paddle is slidably coupled within the slot. The paddle is movable between an extended position and a contracted position with respect to the plunger. Upon placing material into the barrel, such as through an opening in the wall of the barrel, the paddle can be employed to mix the material. After such mixing, the plunger is pressed further into the barrel without removing the paddle, thereby expressing the mixed material from the barrel and compressing the paddle into the slot of the plunger.
