Sterilization Processes for Medical Devices - ISO 11135, ISO 11137, ISO 17665 and ISO 17664

Manufacturers of nearly all medical devices must ensure that their products are free from bacteria and other substances that could transmit infectious diseases to patients and healthcare workers. This requirement applies to single-use medical devices and certain device types that are reusable after suitable reprocessing. Industrial sterilization procedures can involve using various chemicals and techniques, including gamma irradiation, moist heat, and ethylene oxide. However, all sterilization processes must be controlled and validated to ensure the effectiveness of the sterilization process. The same situation applies to reusable medical devices concerning their instructions for reprocessing.

 Sterilization Practices Control and Validation for Medical DevicesRequirements for the development, validation, and routine control of sterilization processes for medical devices and other healthcare products are described within the international standards ISO 11135 (for ethylene oxide), ISO 11137 (for radiation), and ISO 17665 (for moist heat). In summary, an effective sterilization process includes comprehensive documentation of a manufacturer’s validation protocols and reports, along with related laboratory compliance data. For sterilization procedures involving reprocessing (ISO 17664), a comprehensive risk management assessment must be completed. This documentation becomes part of the product dossier or technical documentation, which is generally required for medical device approvals worldwide and placement on the market.

Medical device manufacturers often face several issues in implementing and maintaining appropriate sterilization processes and controls. The science of sterilization is complex and requires expertise in microbiology, chemistry, and engineering. Standards applicable to the control and validation of industrial sterilization processes are extensive and can be difficult to determine how a given standard’s requirements will be interpreted by regulatory authorities during the conformity assessment process. In addition, regulatory requirements applicable to sterilization processes and validation can change in light of new scientific information. These and other issues can slow the regulatory review and approval process for medical device manufacturers.
