The device history record (dhr) was reviewed and no deviations related to this failure mode were found.There were no non-conformances related to the reported issue.The product sample was received inside a generic plastic bag.The catheter presented signs of use (remains of blood).After visual inspection, one cut in the venous extension in the area where the hub connector meets the silicon extension was found.This cut looks irregular.As per the instructions for use (ifu), it is necessary to perform a visual inspection prior to using the device.Do not use the catheter if it is crushed, cracked, cut or otherwise damaged.Clamping the catheter repeatedly in the same spot could weaken the tubing.Exercise caution when using sharp instruments near the catheter.Catheter tubing can tear when subjected to excessive force or rough edges.Inspect the catheter frequently for nicks scrapes, cuts, etc., which could impair its performance.The defect was not identified prior to use, this kind of defect would be detected during leak test.Based on the available information and the result 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 the reported 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; the reported condition was more likely caused due to the improper use of sharp objects, repeated clamping or other similar damage.The evidence provided is enough to discard the manufacturing process as a potential cause.No complaints triggers or trends were identified; therefore corrective or preventive actions are not 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, leak testing and visual acceptance sampling) are in place to prevent nonconforming product from leaving the manufacturing operations.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.
