    Abstract: A drug delivery device may include a housing having an opening, a drug storage container, a plunger rod, and a drive mechanism. The drug storage container may have an inner surface at least partially defining a drug storage chamber and an outer surface defining an outer diameter. The drug storage container may further include a plunger stopper and a delivery member having an insertion end configured to extend at least partially through the opening during a delivery state. The drive mechanism may be activatable to drive the plunger stopper in a distal direction to expel a drug from the drug storage container through the delivery member. The drive mechanism may have an inner surface with an inner diameter greater than the outer diameter of the outer surface of the drug storage container.

    Abstract: A drug delivery device includes an injector and an accessory grip. The injector includes an injector housing defining a housing body having a proximal end, a distal end, and a longitudinal axis extending therebetween, a needle assembly at least partially disposed within the injector housing at the proximal end, and a drive assembly at least partially disposed within the housing. The needle assembly includes a syringe barrel containing a medicament and a needle or a cannula. The drive assembly urges the medicament through the needle or cannula. The accessory grip defines a grip shell having proximal and distal ends, and a body extending therebetween. The proximal end includes a first opening dimensioned to receive a first portion of the injector housing, and the distal end of the grip shell includes a second opening that receives a second opening dimensioned to receive a second portion of the injector housing.
