A devices history record (dhr) review revealed no discrepancies that may have contributed to a complaint of this type of condition.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 received for analysis and investigation; it consisted in one unused uvc catheter, which came inside a pouch in a generic plastic bag.Visually the catheter did not show a defect.Under water testing was performed and there was no leak observed in the catheter.The sample evaluation revealed that the reported condition could not be confirmed.Based on this information the most probable cause was that the clinician confused blood residue with leaking.Blood residues could be caused by the treatment or other condition in the patient.With the available information this is the most possible root cause for this event.Additionally based on the event description, the condition was noticed during use, after priming the catheter.Based on the available information, it can be concluded that product was manufactured according to specifications and the device functioned as intended for an undetermined amount of time; therefore the most probable root cause can be considered as customer perception (blood residues were confused with leaking).There are no trends or triggers found for the reported condition, therefore, a corrective or preventive action is not deemed necessary at this time.It must be noted that in-process controls such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection and visual acceptance sampling are in place to prevent nonconforming product from leaving the manufacturing operations.This complaint will be used for tracking and trending purposes.If information is provided in the future, a supplemental report will be issued.
