  1. Match the model, catalogue, lot and serial numbers on your device against the identifiers on this page.
  2. If the device is implanted or you depend on it daily, speak to your clinician before changing how you use it.

  4. If you are a facility, quarantine affected stock and log the correction.

Who pays for a device recall

The manufacturer funds the remedy. The practical question is usually which link in the chain executes it.

  • If a clinic fitted or supplied the device, start there — they hold the serial-number records the manufacturer needs.
  • Ask for written confirmation that the remedy was applied to your serial number. That is what an insurer or a future clinician will want to see.
  • If you bought it yourself online or from a pharmacy, go to the manufacturer’s recall page rather than the retailer; device claims are handled centrally.
  • Where the remedy is a software update, there is nothing to claim, but do confirm the version changed afterwards.
