1. A fluid delivery device comprising:

  • a cartridge comprising a housing and a stopper, the housing defining a fluid chamber, the stopper being positioned within the fluid chamber and comprising a proximal surface; and

    a syringe comprising an outer body, an inner core, and a needle, the outer body and the inner core cooperating to define a cavity configured to receive at least a portion of the housing of the cartridge, the needle defining a lumen and comprising a proximal tip;

    whereinwhen the fluid delivery device is in a first configuration, at least a portion of the cartridge is positioned within the syringe, the stopper of the cartridge is connected to the inner core, and the proximal tip of the needle is positioned distal of the proximal surface of the stopper;

    when the fluid delivery device is in a second configuration, the proximal tip of the needle extends through the proximal surface of the stopper such that the lumen defined by the needle is in fluid communication with the fluid chamber, wherein the inner core and the stopper are movable distally relative to the outer body and the needle as the fluid delivery device is transitioned from the first configuration to the second configuration; and

    when the fluid delivery device is in a third configuration, the cartridge and the syringe cooperate to prevent relative axial movement between the cartridge and the syringe such that the fluid delivery device is disabled.
