Patent ID: 8333737

Claim:
A syringe system, including a barrel, plunger and piston, comprising: a plastic needle coupled to an end of the barrel, the needle including a proximal taper at a proximal end of the needle, tapering from a proximal first end to a proximal second end toward a longitudinal axis of the needle from a first diameter of the needle to a second diameter of the needle less than the first diameter, the needle further including a distal taper at a distal tip of the needle, tapering from a distal first end to a distal second end toward the longitudinal axis from the second diameter to a third diameter of the needle less than the second diameter, the distal first end separated from the proximal second end; and a cannula assembly including a cannula and cannula hub, the cannula hub having an internal first mating surface that contacts the proximal taper of the needle and an internal second mating surface that contacts the distal taper of the needle, the cannula assembly removably coupled to the plastic needle.
