Sterile Devices

Overview

Class Is devices are medical devices that are supplied in a sterile condition by the manufacturer. Unlike standard Class I devices, Class Is requires notified body involvement specifically for the sterility aspects of the conformity assessment procedure, even though they remain Class I overall.

NB Involvement for Class Is

Under MedDO Annex IV (for the sterility aspects), the manufacturer must engage an NB to assess:

  • The sterilisation process validation
  • The sterile barrier system
  • Transportation and storage maintaining sterility

The NB issues a certificate covering only the sterility aspects. The overall DoC remains the manufacturer's.

Key Standards

  • EN ISO 11135 — Sterilisation of health-care products: ethylene oxide
  • EN ISO 11137 — Sterilisation by radiation
  • EN ISO 11607 — Packaging for terminally sterilised medical devices
  • ISO 17665 — Sterilisation by moist heat (steam)
