One catheter with attached monoject 1.5 cc limited volume syringe and two three-way stopcocks was returned for evaluation.A non-edwards introducer with contamination shield was located on the catheter body from tip to 87.5 cm proximal from tip.Blood was visible on catheter body.As received, the thermal filament and the cover was damaged at approximately 21.9 cm from the catheter tip.The size of the damaged area was 1.5 mm x 2.0 mm.The edges of the thermal filament appeared to match up, however, the edges of thermal filament cover were uneven and folded, thus it was not able to check if the edges matched up.The catheter was connected to vigilance ii monitor and "check thermal filament connection" error message was shown.An intermittent condition was confirmed on the thermal filament.After removing the thermal filament and the cover, the catheter body was also found to be damaged.The damage on the catheter body did not enter any lumens.The thermistor was found to read 37.0 c when submerged into a 37.0 c water bath.The thermistor circuit was continuous and there were no open or intermittent conditions observed.No visible inconsistency was observed on eeprom data.Thermal filament connector was opened with no visible abnormalities.All through lumens were patent without any leakage or occlusion.The balloon inflated clear, concentric and remained inflated for more than 5 minutes without leakage.No visible damage to the balloon, returned syringe or connectors was found.Balloon inflation test was performed using returned syringe with 1.5 cc air.Visual examination was performed under microscope at 10x 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 cco measurement issue was confirmed.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.With any hemodynamic monitoring, patient parameters can change quickly and dramatically.Patient parameters should correlate with the patient¿s clinical manifestations.In this case it is unknown whether any user or procedural factors may have contributed to the stated event.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.
