10. The medication delivery device of claim 5, wherein the linear drive component comprises an electronic actuator and wherein the user input is in electrical communication with the electronic actuator and is operable to cause the electronic actuator to move axially through the housing.

11. The medication delivery device of claim 1, wherein the radial opening comprises a length at least long enough to receive a length of the disposable portion and a width at least wide enough to receive a width of the disposable portion.

12. The medication delivery device of claim 1, wherein the radial opening is uncovered.

13. The medication delivery device of claim 1, wherein the carrier includes a pair of horizontal protrusions, and wherein a pair of horizontal recesses in the guide accepts the pair of horizontal protrusions in a radial direction to removably couple the carrier with the guide.

14. The medication delivery device of claim 1, wherein the actuator assembly further comprises a lock assembly that rotates axially to unlock the medication delivery device and extends the disposable portion towards a basecap at the distal end of the housing that decouples a shield from the needle.

15. The medication delivery device of claim 14, wherein when a user input is actuated, the actuator assembly axially rotates and advances the disposable portion towards the distal end of the housing to the deployed state.

16. The medication delivery device of claim 15, wherein the actuator assembly is configured to retract when the user input is actuated for a second time and the disposable portion retracts towards the proximal end of the housing to the retracted state.

17. The medication delivery device of claim 1, wherein: the syringe is entirely visible through the radial opening of the housing in the stowed state and the retracted state; andthe syringe is partially visible through the radial opening of the housing in the deployed state.

18-25. (canceled)

26. A syringe assembly for a reusable assembly that when combined is capable of delivery of medication, comprising: a syringe comprising a barrel configured to contain a medication, a piston positioned within the barrel, a needle positioned at a distal end of the barrel,a carrier coupled to a proximal end of the barrel, wherein the carrier includes a pair of protrusions extending radially outward and configured to be removably coupled with a linear shuttle system of a reusable assembly, and when coupled, the proximal end of the barrel is sized to receive a plunger drive of the reusable assembly,and the carrier is moved radially from the linear syringe system to decouple the carrier from the linear syringe system.
