Investigation ¿ evaluation: a review of the complaint history, device history record, documentation, instructions for use (ifu), manufacturing instructions, quality control, specifications, and trends of the complaint device were conducted during the investigation.Additionally, a visual inspection of a representative device from a different lot was performed.The visual inspection of the representative device showed no damage.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.The manufacturing documents in place at the time of manufacture were reviewed and it was found that the catheter tubing is quality control checked and no notable gaps in production or processing controls were noted.The risk specification for this product includes difficulty removing the catheter from the guiding cannula and identifies that multiple risk controls are in place to mitigate the risk of the catheter separation.A review of the device history record for lot 7810417 showed no nonconforming events which could contribute to this failure mode.A complaint history search of the manufacturer's database identified this to be the only complaint associated with lot 7810417.The ifu warns that extreme care must be exercised during manipulation and withdrawal of the catheter to prevent the catheter pulling apart.Since the hub separated, the root cause was trended as possible product use or handling related due to the user¿s technique while withdrawing the catheter from the guiding cannula.However, based on the information provided, the examination of the representative product, and the results of our investigation, a definitive root cause could not be determined.The event was confirmed per customer testimony.We have notified the appropriate personnel and will continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.
