Summary

On February 7, 2024, the FDA held the third in a series of medical device sterilization town halls to:

• Understand FDA expectations for initial premarket submissions based on the 510(k) Sterility Guidance, including recent guidance changes, sterilization modality categories, and what to include in a submission.
• Understand additional device and submission considerations for sterility that impact FDA review.

Background

Sterilization is a critical step in the manufacturing process for certain medical devices. Sterilization of medical devices help prevent serious infections. Inadequate sterilization can lead to life-threatening infections.

Medical devices are sterilized in a variety of ways including using moist heat (steam), dry heat, radiation, ethylene oxide (EtO) gas, vaporized hydrogen peroxide, and other sterilization methods (for example, chlorine dioxide gas, vaporized peracetic acid, and nitrogen dioxide).

Ethylene oxide is the most commonly used method to sterilize medical devices in the United States, and it is widely used by medical device manufacturers and contract sterilizers worldwide. End of
Translation Other existing sterilization modalities cannot currently replace the use of EtO for many devices. While some novel technologies hold promise, innovative alternative sterilization methods are still in early phases of research and development.

The FDA is committed to reducing reliance on EtO sterilization use while ensuring the integrity of the supply chain so that patients and providers have continued access to the sterile devices they need. To meet this goal, FDA continues to take a multipronged approach, including regulatory flexibilities, supply chain analysis and mitigation, collaboration, innovation, and communication, including this regular series of town halls.
