A cutting element (43) capable of cutting the cuttable distal end andthe cuttable support includes a body portion (44) having a proximal end (45),a distal end (46), a side wall (47) therebetween and a passageway (50)therethrough. The distal end (46) of the body portion (44) includes a cuttingedge (48) and a raised distally projecting tapered cutting tooth (51) havingdistally converging edges (52). At least one tooth edge includes a sharp sidewall (55) for cutting the distal end of the plunger and the needle support.
