An investigation of the reported condition was performed.A device history review revealed no discrepancies that may have contributed to a complaint of this issue.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 device history record (dhr) are reviewed for accuracy prior to product release.One used uvc catheter sample was received for testing and investigation.The sample presents a residue of blood inside the tubing.Additionally the sample was returned inside a generic bag.Under water testing was performed and a leak below the strain relief could be identified in the catheter.However the origin of the leak could not be observed with a naked eye.A magnified picture was taken and clean cut below the strain relief was observed.The device history record (dhr) was reviewed and no deviations related to this issue mode were found.The product sample was returned to the manufacturing site for evaluation.Based on the evaluation and available information, it can be concluded that product was manufactured according to specifications; therefore the most probable root cause can be considered as unintentional misuse; this product was most likely damaged during use caused due to inappropriate manipulation by the user.No harm was report by this complaint, and therefore no corrective or preventive actions are required 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.
