  • Patent number: 11826480
    Abstract: A drug delivery sterilization system includes a housing defining at least one receptacle, a container assembly having first and second ends, an elongated portion extending therebetween, and an electron beam or x-ray generator disposed near the housing. The container assembly includes a container having a container contact region at the second end and an inner volume to contain a medicament, a seal member having a seal member contact region to form a sealing interface with the container contact region, and a coupling device adapted to sealingly couple the seal member to the container. The container assembly is at least partially disposed in the receptacle such that the second end of the container is exposed through the housing. The electron beam or x-ray generator generates a sterilizing beam that penetrates the seal member to sterilize the sealing interface.

  • Patent number: 11813426
    Abstract: Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a housing, a container, a trigger member, and an interlock assembly. The trigger member may be selectively moveable relative to the housing to activate operation of at least one activatable element of the drug delivery device. The interlock assembly may include a lever mounted rotatably relative to the housing, a proximity sensor moveable between a first position extending beyond an exterior surface of the housing and a second position retracted toward the housing, and a rotational biasing member operably connected to the proximity sensor via the lever. When the proximity sensor is in the first position, the interlock assembly may limit movement of the trigger member relative to the housing. The rotational biasing member may be configured to exert a torque biasing the proximity sensor toward the first sensor position.
