Abstract
A method of sterilizing a cartridge that has a side wall and a medicant in the cartridge. The cartridge is placed within an outer sleeve and the outer sleeve is sealed to the side wall of the cartridge with a wiper seal to form a hermetic microbial barrier. A breathable microbial membrane is provided over one end of the sleeve. The cartridge and the outer sleeve are subjected to gas sterilization in a sterilization chamber. Any sterilizing gas remaining after sterilization is removed.
