Investigation ¿ evaluation: a review of the complaint history, device history record, instructions for use (ifu), manufacturing instructions, quality control, and a visual inspection of the returned device were conducted during the investigation.The visual inspection of the returned device confirmed that the sheath flaring was severely damaged.The diameter was measured to be 6 mm, which is outside specification.Also, the flare had frayed, and some damages/dents were noted.This damage appeared as if it was caused by a tool, and when the complaint sheath was compared with a testing sheath, the most distal part of the flared portion appeared to be cut/removed.However, when a similar test fitting was attached to the complaint sheath, the fitting did not slip the sheath despite the forces which were experienced.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.A review of the device history record showed no nonconforming events which could contribute to this failure mode.It should be noted there were no other reported complaints for this lot number.Based on the information provided, the examination of the returned product, and the results of our investigation, a definitive root cause could not be determined.It is likely, however, that product use, or incorrect handling, is was related to the event.We will continue to monitor for similar complaints.Per the risk assessment, no further action is required.
