Suture Biological Indicator for the Narrow Channels of Medical Instruments

Recently using an endoscope with a narrow channel has become very popular in surgery or invasive examination in clinical settings. In healthcare service, it is essential to supply those reusable critical items with high sterility assurance quality. However, most of the flexible endoscopes are not sterilisable with steam. Thus, the need of low temperature sterilisation has been increased for equipments that are easily affected by heat . For sterilising narrow channels, low temperature hydrogen peroxide vapor sterilization is one of the most useful and reasonable ways. In ISO 14937 2009, it is mentioned that any change in product, its package, or the presentation of product for sterilization shall be assessed for the effect on the appropriateness of the sterilization process. However, the validating method for the narrow channel has not been well-established yet.
