A device history record (dhr) review revealed no discrepancies that may have contributed to a complaint of this failure mode.All quality assurance testing performed during manufacturing was acceptable.The quality assurance review of the visual, physical and dimensional evaluation results indicated that the product met specification requirements.In addition, all dhr are reviewed for accuracy prior to product release.The product sample was returned for investigation, it consisted in a mahurkar catheter 11.5fr x 13.5cm that is different to product reported, a marked guide wire, an introducer needle, a dilator 10fr, a dilator 12fr and an original polybag with its respective label.The venous extension showed signs of use and the other components did not show signs of use.Visual inspection was performed and it revealed one cut in the venous extension and the blue adapter was detached from the extension and was not returned.The red adapter was not well placed in the extension.The extensions did not present others marks.Additionally, the clamps were reviewed and as a result no issues or irregularities were found.In the evaluation of the sample the lot number was found.An ishikawa diagram was used to determine the potential causes for this event.Manufacturing performs 100% pressure leak testing.The issue was not identified prior to use and functioned as intended for the reported amount of time.As per the instructions for use (ifu), the customer has to perform a visual inspection before using the device.The sample was received damaged after being in use, this is evidence that the catheter was manipulated; this manipulation could be associated to the damaged found in the extension.The reported condition has been confirmed.The most probable root cause can be considered as misuse.No complaint triggers or trends were identified; further actions are not required.It must be noted that in-process controls such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection, leak testing and visual acceptance sampling are in place to prevent nonconforming product from leaving the manufacturing operations.As per procedure, manufacturing performs 100% leak testing and a 100% visual inspection at the final stage of production, which would identify this issue in the catheter assembly.No additional actions are required.This complaint will be used for tracking and trending purposes.
