Abstract

An injector (100) may include a container (102) having a wall (110) with an interior surface (112) and a seal assembly (140) with an interior surface (142), the interior surfaces (110) of the wall (110) and the seal assembly (140) defining a closed sterile reservoir (150) filled with a drug product. The injector (100) may also include a fluid delivery system comprising a clean, unsheathed, rigid container needle (180) having a point (182) disposed only partially through the seal assembly (140) in a storage state, and disposed through the interior surface (142) of the seal assembly (140) into the sterile reservoir (150) in a delivery state. Further, the injection may include an actuator (106) that is adapted to move the container needle from the storage state to the delivery state.
