  • Publication number: 20200338271
    Abstract: Fill-finish assemblies facilitating the manufacture of a drug delivery device are disclosed. The fill-finish assembly may include a container, an insertion mechanism, a fluid pathway connection assembly disposed between the container and the insertion mechanism, and a carrier. The insertion mechanism may include a delivery member and an insertion mechanism housing. The insertion mechanism may be configured to move the delivery member from a retracted position inside the insertion mechanism housing to a deployed position outside the insertion mechanism housing. The fluid pathway connection assembly may be selectively activatable to establish fluid communication between the container and the delivery member. The carrier may have a hollow interior containing at least a portion of each of the container, the insertion mechanism, and the fluid pathway connection assembly.

  • Publication number: 20200289745
    Abstract: Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a main housing having an exterior surface releasably attachable to a patient, a container disposed in an enclosed space defined by an interior surface of the main housing, and a drive assembly. The container may include a reservoir containing a drug and a stopper. The drive assembly may include drive housing and a tether which slidably engages and is pulled taut against a guide surface of the drive housing. A first end of the tether may be wound around a capstan which is mounted rotatably relative to the drive housing. A second end of the tether may be operably connected to a stopper biasing member. The tether may initially retain the stopper biasing member in an energized state. When released, the stopper biasing member may expand to move the stopper through the reservoir.

  • Publication number: 20190365987
    Abstract: Modular fluid path assemblies are provided that include conduit, coupling, and needle portions of a fluid path fluidly coupled to an outlet of a container. The modular fluid path assemblies further include a needle shield having a tip of the needle embedded therein. So configured, in embodiments, the modular fluid path assemblies can be sterilized, a medicament can be filled in the container, and a stopper inserted in the container so that the pre-sterilized and pre-filled modular fluid path assemblies can have a closed container integrity (CCI) seal.

  • Publication number: 20190060562
    Abstract: An insertion mechanism for a wearable drug delivery device includes a needle hub, a needle coupled to the needle hub, a flexible boot removably coupled to the needle hub, and a cannula coupled to the flexible boot. The needle hub, the needle, the flexible boot, and the cannula are movable between a first position and a second position. Upon moving the needle hub, the needle, the flexible boot, and the cannula from the first position to the second position, the cannula engages a floor member to restrict movement of the cannula and the flexible movement towards the first position.
