The EDA classifies variations into minor, major, and significant categories, each with distinct submission requirements. Proper classification is essential for regulatory compliance, approval timelines, fees, and risk management.
Types of Variations
Minor Variations Administrative updates (labeling corrections, company contact info)
Often submitted as notifications, with faster processing
Major Variations Affect device safety, efficacy, or performance
Examples: design changes, sterilization process updates, site changes
Typically require prior approval and full dossier submission
Regulatory Implications
Determines submission pathway and fees Influences approval timelines Identifies whether Scientific Committee review is required
Compliance Tips
Assess each variation carefully Document classification rationale Plan submissions strategically Example: Changing sterilization method of a sterile accessory is a major variation; adding a second importer may be minor.
