One catheter with attached monoject 1.5 cc limited volume syringe and 3 three-way stopcocks was returned for evaluation.A non-edwards contamination shield was located on the catheter body between 82 cm and 112 cm proximal from the catheter tip.No packaging or introducer was returned.Blood was observed from the strain relief of the optical module connector.Catheter body was tied by a suture at around 56 cm proximal from the catheter tip.The attached contamination shield was removed for evaluation.No visible damage to the catheter body, balloon, or returned syringe was observed.Leak testing was performed and all through lumens were patent without any leakage or occlusion.Balloon inflated clear and remained inflated for 5 minutes without leakage.The optical module connector housing was opened and blood was observed around the strain relief and housing bonding section.A cut down of the optical module connector extension tube was performed at 2 cm distal from the strain relief.No blood was found inside the extension tube.Leak testing was performed using a tuohy borst type fitting connected to the cut section of the optical fiber lumen extension tube and no leakage was observed.Additional examination of the catheter found that the catheter had no inter-lumen leaks, cuts or punctures that would account for the blood inside the optic connector and strain relief.No blood was observed inside the optic extension tube or any of the catheter lumens.The connector is located outside the catheter body and if the catheter does not have an inter-lumen leak and there is no catheter body damage, there should be no blood inside the optic connector.No defect was found with the catheter; therefore, the blood may have entered from an external source.Balloon inflation test was performed using returned syringe with 1.5 cc air.Visual examination was performed under microscope at magnification 20x and with the unaided eyes.The customer report of blood leakage was not confirmed.There was no evidence of a manufacturing nonconformance.No further actions will be taken at this time.
