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 dhrs are reviewed for accuracy prior to product release.The sample was received for analysis and investigation.Visual inspection was performed and it revealed that the catheter presented signs of use.Additionally, the clamps were reviewed and as a result irregularities were not found.The arterial extension presented marks, as if there was the use of an instrument.In order to confirm the reported condition functional testing was required.An ishikawa diagram was used to determine the potential causes for this event.The reported condition has been confirmed.Based on the available information and the results of the dhr review that showed no deviations, it can be concluded that product was manufactured according to specifications and the device functioned as intended for an undetermined amount of time.Moreover, 100% devices are inspected for leaks or cuts in the extensions per procedure.Therefore, the most probable root cause can be considered as misuse.This issue was more likely damaged caused during use due to the use of strong cleaning agents, excessive force during of use, repeated clamping or other similar damage.The evidence provided is enough to discard the manufacturing process as a potential cause.No trends or trigger were identified.No harm was reported for this complaint and this is not a manufacturing/supplier related event, therefore, no further corrective or preventive actions are not deemed necessary at this time.It must be noted that in-process controls, such as personnel training, incoming quality acceptance testing for (b)(4) 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 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.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
