After further review of additional information received the following sections have been updated accordingly: b5, g3, g6, h2, h3, h6, and h10.Complaint conclusion: as reported, there was blood on the hub side of a 6f.070in extra back-up (xb) rca sidehole (sh) 100cm vista brite tip guiding catheter.There were no reports of patient injury.The user tried to use the vista brite tip for percutaneous coronary intervention (pci), but he was not able to use it due to the issue found.A non-sterile unit of catheter 6f.070 xb rca sh 100cm was received for evaluation.During the visual inspection, a kinked/bent condition was observed on the body of the catheter located 69.9 cm from the distal tip.No other damages or anomalies were observed on the returned device when viewed by the naked eye.Inner diameter (id) and outer diameter (od) measurements were taken near the damages and were found within specification.A leakage test was performed on the hub by attaching a syringe and injecting water.A crack was noted on the hub when attaching the syringe.Sem analysis was performed on the cracked hub and presented evidence of fatigue striations and plastic deformation.The reported ¿luer hub - leakage¿ and ¿luer hub-cracked¿ was confirmed since leakage from a cracked hub was noted during the functional test.Plastic deformation and fatigue striations found on the hub are commonly associated with separations caused by material tensile overload.While the exact cause of the crack cannot be conclusively determined during the analysis, it is assumed the hub was induced to a tensile force that exceeded its yield strength prior to cracking.Storage or handling factors may have contributed to the event.Users are trained to inspect for signs of damage prior to and during use.Any product with damage is not to be used.Information for safety is provided in the products labeling with the intent to make the user aware of the risks.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿store in a cool, dark, dry place.Do not use open or damaged packages.Inspect the guiding catheter before use to verify that its size, shape and condition are suitable for the specific procedure.Inspect the guiding catheter upon removal from packaging to verify that it is undamaged.Warning: do not use a guiding catheter that has been damaged in any way.If damage is detected, replace with an undamaged guiding catheter.¿ based on the available information, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
