Corrected data: product code: dqx.Investigation - evaluation: a review of device history record, documentation, quality control documents, manufacturing instructions, complaint history, and specifications was conducted during the investigation.The complaint device was not returned; therefore, device failure analysis and physical examination of the device used in this case could not be performed.The wire guide is manufactured according to specification detailing and verifying the geometry of the wire guide.After assembly of the product, it is independently inspected, including 100% verification for dimensional and visual criteria as part of quality control procedures.In summary, there are adequate controls in place to ensure the product is manufactured as intended.The device history record for lot number 7425022 was reviewed and no related non-conformances were identified.A search of our complaint records indicates that this is the only complaint on the lot number at the time of investigation.It is possible that the wire guide was met with forces beyond its intended use or encountered a tortuous patient anatomy, leading to the failure described.It is also possible that the wire guide was withdrawn through a needle which could have led to the device sheering off in the patient.However, without visual, dimensional, or functional testing of the involved components, a definitive root cause could not be determined.A quality engineering risk assessment was performed to address this failure mode.No further action is required.We will notify the appropriate personnel and continue to monitor for similar complaints.
