The plunger having a rear tamping knob on one end and an ejection tip on the other end. The rear knob having a matching frusto-conical portion used for tamping the fibrin clot material from the collection chamber into the ejection chamber. The tip of the plunger being insertable into the injection chamber to push the fibrin clot material out of the delivery device.
