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.In addition, all dhrs are reviewed for accuracy prior to product release.The physical sample involved in the reported incident was not returned for evaluation.Two photos were provided by the customer.The picture showed a catheter inside the patient with blood leaking from the venous extension.The instructions for use (ifu) state the customer must perform a visual inspection before using the device and that clamping the catheter repeatedly in the same spot could weaken the tubing.It also states to caution when using sharp instruments near the catheter because the catheter tubing can tear when subjected to excessive force or rough edges.The reported condition has been confirmed.Based on pictures provided by customer, it can be concluded that the most probable root cause can be considered as damaged during use caused by the use of strong cleaning agents, sharp objects, excessive force, or repeated clamping.No trends or triggers have been found.Therefore, no action is deemed necessary at this time.If information is provided in the future, a supplemental report will be issued.
