Unique device identifier (udi): (b)(4).The scalp clip was returned for evaluation: device history record (dhr): no anomalies occurred during the manufacturing process.Failure analysis - in the failure analysis that was performed, the returned unit did not work as intended as the failure analyst determined there was a brown spot/particulate in the packaging.The complaint could be verified through failure analysis.A 6m root cause analysis was performed exploring the areas of man, method, machine, materials, measures and mother nature.In addition, the "fmea" was reviewed to determine potential causes for contaminants present in the packaging.After review of the 6m areas and the "fmea", the likely root cause is related to man or method.Per the "fmea" a likely cause is an error in the supplier manufacturing process, and depending at which step in the process, it is possible that this could have been attributed to operator error.The complaint was confirmed.
