Abstract
The sealed package is sterilized with a sterilant gas such as ethylene oxide prior to application of a desiccant pack. The desiccant pack is applied after sterilization and held in place by a metallic foil which is impermeable to moisture. A moisture permeable layer separates the desiccant pack from the plastic tray-like layer in which the surgical instrument is disposed. Absorbable co-polymer staples are maintained moisture-free by virtue of the desiccant pack being located on the opposite side of the moisture permeable layer.
