What to do about Device

Fresenius Medical Care Renal Therapies Group, LLC — The manufacturer or the FDA identified a problem with this device. The model, lot and catalogue numbers are what define the scope.

  1. Match the model, catalogue, lot and serial numbers on your device against the identifiers on this page.
  2. Ask the supplier or clinic that provided it what the remedy is in your case.
  3. If you are a facility, quarantine affected stock and log the correction.
  4. Report device problems to the FDA through MedWatch.

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.
