Investigation ¿ evaluation: a review of the complaint history, device history record, manufacturing instructions, quality control, and a visual inspection of the returned devices were conducted during the investigation.The visual inspection of the returned devices noted no damage on the surface of the sheaths or dilators, except for damage to the distal tip of the sheaths.The inner and outer diameters of both sheaths were measured, and all attributes were within specifications.Additionally, a document-based investigation was performed.There is no evidence to suggest the finished products were not made to specifications.Numerous design verification and validation activities have been performed to ensure that these devices meet design requirements.Review of the device history record of the finished product shows one nonconforming event that could contribute to this failure mode.The affected part was reworked prior to completion of the work order.A complaint history search revealed that there were no other reported complaints for this lot number.Per manufacturing quality control documentation, the sheath distal tip is inspected and confirmed to be sanded and free of rough edges.Based on the information provided, the examination of the returned products, and the results of our investigation, a definitive root cause could not be determined.We will continue to monitor for similar complaints.Per the quality engineering risk assessment, no further action is required.
