The present invention is directed to a needle retention assembly, an injectate delivery system, a needle, and a safety mechanism, all of which are for use with an injection device. The needle retention assembly includes a needle offset nut which is configured to removably attach to a needle retention nut and to provide support to the needle. The injectate delivery system includes an injectate holding compartment, a plunger, and a resilient member. The needle has a sidewall defining a longitudinal channel and includes at least two orifices in the sidewall, but does not include an orifice at a tip of the needle. The safety mechanism includes a dual switch that includes two switch elements that are each positioned on opposing sides of a handle of the injection device. |
