About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
