The reported event of leakage issue was confirmed.3 punctures were found on the catheter body.Puncture a was 1.0 mm, puncture b was less than 0.5 mm, and puncture c was 1.5 mm in length.The thermistor, thermal filament and optical module connector extension tube were cut in half just distal of the connector for leak testing.Leakage was observed from the puncture a and c when air was injected into the pa distal lumen, proximal injectate lumen and optical module lumen.No leakage was observed from other through lumens, thermistor lumen and thermal filament lumen.Puncture b did not appear to enter any lumens.As received, the blood stain was observed inside of strain relief of optical module connector.Optical module connector was opened and the blood was observed inside of the connector.The balloon inflated clear, concentric and remained inflated for more than 5 mins.Without leakage.Distal thermal filament cover bonding site was torn.The torn edges appeared to match up.No other visible damage or abnormality was found from balloon and returned syringe.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.
