MEDICAMENT DELIVERY DEVICES FOR ADMINISTRATION OF A MEDICAMENT WITHIN A PREFILLED SYRINGE

Abstract: an apparatus includes a housing, a medicament container and a movable member. the medicament container is movable within the housing between a first position and a second position in response to a force produced by an energy storage member. a proximal end portion of the medicament container includes a flange and has a plunger disposed therein. a first shoulder of the movable member exerts the force on the flange to move the medicament container from the first position to the second position. a portion of the first shoulder deforms when the medicament container is in the second position such that at least a portion of the force is exerted upon the plunger. a second shoulder of the movable member exerts a retraction force on the flange to move the medicament container from the second position towards the first position.
