Abstract: A medical article is heated to a temperature of at least 80 degrees F. Then, the medical article is loaded into a housing. After loading, the medical article may be heated within a sterilization-sealing station, by pressurizing the housing with steam through gas injection pins. The steam is supplied through gas injection pins. A sterilizing gas is also supplied to the medical article within the sterilization-sealing station. A determination is made as to how much time is required for the residual sterilizing gas to dissipate from the housing. The medical article is maintained in a degassing area until residual sterilizing gas dissipates from the housing. The housing may be formed between the first and second webs, which are sealed together after sterilization.
