The reported event of cco measurement issue was not able to be confirmed during evaluation.No fault messages showed up on the lab hemosphere monitor when the catheter was connected.The thermistor was found to read 37.0 c when submerged into a 37.0 c water bath.Thermistor temperature reading accuracy is plus negative 0.3 c per hemosphere manual.The catheter ran cco in 37.0 c water bath on hemosphere monitor for 5 mins.Without error.Thermistor and thermal filament circuit were continuous, there were no open or intermittent conditions.No visible inconsistence was observed on eeprom data.Resistance value of thermal filament circuit was measured 40.11 ohms, which was in specification per drawing (b)(4) rev y.Specification is 37.26 plus minus 3.64 ohms.Both thermistor and thermal filament connectors were opened and found no visible inconsistencies.As received, distal heater bonding was torn, and blood was observed in heater shrink wrapping.Torn edges were not able to match up.2 indentations were observed on catheter body at 41.8 cm and 42.5 proximal from catheter tip, where the connection area of non ew introducer and contamination shield adapters located.No other visible damage or inconsistency was observed from catheter body, balloon or returned syringe.All through lumens were patent without any leakage or occlusion.The balloon inflated clear, concentric and remained inflated for more than 5 mins.Without leakage.Further evaluation regarding supplier related quality issues is under investigation.The lot number was not provided thus a device history record was not reviewed.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 a part of the monthly review.
