  • Method for external sterilization of drug delivery device
    Patent number: 12233177
    Abstract: A method of externally sterilizing a drug delivery device utilizing Nitrogen Dioxide (NO2) is provided, including placing the drug delivery device in a sterilization chamber, introducing into the chamber a dose of NO2 having a concentration of between about 2 and 20 milligrams per Liter by applying a vacuum level of between about 10 and 600 Torr and holding the vacuum level for a dwell time of between about 2 and 20 minutes, repeating the step of introducing into the chamber a dose of NO2 for a number of pulses between about 1 and 24, purging the sterilization chamber of at least substantially all of the NO2, and aerating the sterilization chamber.

  • STOPPER PLACEMENT IN A SYRINGE
    Publication number: 20250009976
    Abstract: A method of placing a plunger into a syringe barrel filled with a drug product. The method includes aligning a stopper with a longitudinal axis of a syringe barrel. The syringe barrel includes a proximal end, a distal end, and a reservoir. The drug product is disposed in the reservoir at the distal end. The method includes applying a vacuum pressure to the reservoir of the syringe barrel. The method includes pushing the stopper with a plunger rod into the reservoir of the syringe barrel to a first depth. The method includes removing the plunger rod from the reservoir of the syringe barrel after pushing the stopper to the first depth. The stopper migrates to a second depth that is different than the first depth in response to a pressure differential in the reservoir of the syringe barrel.
