One catheter with attached monoject 1.5 cc limited volume syringe, 2 three-way stop cocks and a non-edwards plug were returned for evaluation.A non-edwards contamination shield was located on the catheter body between 47cm and 93 cm proximal from the catheter tip.No packaging or introducer was returned.Blood was observed from the optical module connector.The attached non-edwards contamination shield was removed for evaluation.The catheter was found to have an interlumen leakage in the catheter body at 103 cm proximal from the catheter tip between the proximal injectate and optical fiber lumens.The distal lumen was patent without any leakage or occlusion.No visible damage to the catheter body, balloon, or returned syringe was observed.The balloon inflated clear, concentric and remained inflated for more than 5 minutes without leakage.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.The 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.

It was reported that aortic valve replacement (avr) and coronary artery bypass grafting (cabg) was performed.After anesthesia induction, the catheter was inserted.After an hour of use, blood was noted at the connection between the om-2 cable and the optical module connector.The blood was removed, but it appeared again after few minutes of use.The catheter was replaced and then the problem was solved.There were no problems with om-2 connector.There were no patient complications reported by the customer.
