One catheter with attached monoject 1.5 cc limited volume syringe was returned for evaluation.A non-edwards contamination shield was located on the catheter body between 48 cm and 100 cm proximal from the catheter tip.No packaging or introducer was returned.As received, blood was observed from the optical module connector and from the strain relief.A puncture, <0.5 mm long, and a scratch mark, approximately 0.5 mm long, were found on the catheter body at 32 cm proximal from the catheter tip.The puncture entered into the distal and optical fiber lumens.No leakage was observed from the thermistor connector.Proximal injectate lumen was 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 or returned syringe was found.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 blood leakage 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.
