One catheter with attached monoject 1.5 cc limited volume syringe and two three-way stopcocks was returned for evaluation.A non-edwards contamination shield was located on the catheter body between 92.7 cm and 111 cm proximal from the catheter tip.The contamination shield was removed for evaluation.Two punctures were found on opposite sides of the catheter body, located at 28.8cm from the catheter tip.The size of the punctures were approximately 0.5mm and <0.5mm.Visual examination also found that the catheter body was collapsed at 94.5cm from the catheter tip.Clotted blood was observed inside the thermistor connector.Leakage was observed from both punctures when air was injected into the thermistor lumen and fiber lumen.No other visible damage to the balloon, catheter body, or returned syringe was found.The balloon inflated clear and concentric, and remained inflated for 5minutes without leakage.Distal lumen and proximal injectate lumen were patent without any leakage or occlusion.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.Customer report was confirmed during the analysis.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.Per the reporting clinician, the reporter stated that the most likely cause was that the catheter was inadvertently sutured to the ra during a surgical procedure.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.
