Abstract: A method of delivering a liquid sterilant to a sterilizer involves piercing a cell of a cassette with a first needle having a first lumen, flowing a gas into the cell to pressurize the cell relative to a pressure within the first lumen and drive the liquid sterilant out of the cell through the first lumen. The liquid sterilant travels from the lumen to a vaporizer in the sterilizer.

Abstract: A laminated package comprising two panels of a moisture impervious material such as aluminum foil coated on adjacent interior surfaces with a heat sealable resin such as polypropylene, and peripherally heat sealed at the edge margins with a continuous and substantially bubble free seal to enclose a moisture sensitive suture within the package. The package is highly resistant to penetration by water vapor, and moisture sensitive sutures thus packaged are well protected against degradation by atmospheric moisture diffusing into the package through the heat seal layer during storage.
