One catheter with attached monoject 1.5 cc limited volume syringe and a pressure tubing set was returned for evaluation.Proximal injectate lumen hub with a non-edwards stop cock was also returned.A non-edwards contamination shield with introducer was located on the catheter body between 0.5 cm and 76 cm proximal from the catheter tip.Clotted blood was observed inside the catheter.Contamination shield with introducer was removed for evaluation.Proximal injectate lumen hub was completely detached from the extension tube.The cross-surface at the extension tube was rough and blood was observed inside the extension tube.The cross-surface at the hub was smooth and even.The proximal injectate lumen was occluded with clotted blood and it was not able to remove the blood with warm water or a guidewire.The pa distal lumen was patent without any leakage or occlusion.Catheter body was found collapsed at 5.5 cm proximal from the catheter tip.The balloon inflated clear, concentric and remained inflated for more than 5 minutes without leakage.No visible damage or abnormality to the balloon or returned syringe was observed.Balloon inflation test was performed using returned syringe with 1.5 cc air.Visual examination was performed under microscope at 20x magnification and with the unaided eyes.A device history record review was completed and documented that device met all specifications upon distribution.Customer report of proximal injectate lumen hub detachment was confirmed during the evaluation as the proximal injectate lumen hub was completely detached from the extension tube.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint and implement any necessary corrective actions.Invasive procedures involve some patient risks.Although serious complications are relatively uncommon, the physician is advised, before deciding to insert or use the catheter, to consider the potential benefits in relation to the possible complications.The techniques for insertion, methods of using the catheter to obtain patient data information, and the occurrence of complications is well described in the literature.It is common clinical practice to inspect all products before usage.These products are used by highly trained clinicians, experienced in identifying and mitigating any hazards that arise during use.The catheter can be exchanged for another one, causing a minor delay in treatment or monitoring.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.(b)(4).
