terminal sterilization
Final sterilization of medical devices in their final packaging before distribution or use.
Full Definition
Terminal sterilization refers to the sterilization process applied to medical devices in their final packaging, ensuring sterility is maintained until the package is opened for use. This approach contrasts with sterilization of items that are subsequently packaged or assembled under aseptic conditions. Terminal sterilization is considered the gold standard for medical device sterilization because it eliminates the risk of contamination during packaging and handling. The process must be validated to ensure that sterilizing agents can penetrate all packaging materials and reach all surfaces of the device while maintaining package integrity.
Usage
Usage note: Distinguish from 'final sterilization' when emphasizing the in-package aspect.
