Investigation - evaluation: a review of the complaint history, drawings, dimensional verification, device history record, instructions for use (ifu), manufacturing instructions, specifications, quality control, and visual inspection of the returned device was conducted during the investigation.We received only one small portion of the kopans breast localization needle back for investigation.Visual examination confirms damage to the surface of the needle.The distal loop appears to be in a damaged condition.Both proximal and distal areas exiting out of the noted cannula appears to be in a damaged condition.The proximal separated end appears to be elongated, twisted, and deformed.No biological matter is present throughout the length of the device.A document-based investigation was performed.There is no evidence to suggest the finished product was not made to specifications.Review of the device history record of the finished product shows no nonconforming events that could contribute to this failure mode.A complaint history search revealed that there were no other reported complaints for this lot number.Based on the information provided, examination of the returned product, and the results of our investigation, a definite root cause could not be determined.
