The reported complaint that the patient was not cooling using the solex catheter (lot 172888) was not confirmed during functional testing of the returned catheter.No issues or discrepancies were found.No device malfunction was observed during the testing.All the lumens were flushed without resistance and the catheter functioned as intended.Visual inspection of the returned catheter was performed.There were no kinks or physical damage observed on the catheter.Observed blood had accumulated and dried up on the catheter's serpentine balloon and in luered tubings.A functional pressure leak test of the returned catheter was performed.All infusion ports and lumens were flushed without resistance.The catheter was connected to a pressurized inflation device, and the balloons were fully inflated when pressurized up to 100 psi, and no issues were observed.The balloons did not leak during inflation and deflation.In addition, the returned catheter was connected to a known good start-up kit (suk) and ran on a peristaltic pump for 10 minutes at a high-speed rate.No leak or damage was found.The red pinwheel was rotating as normal and the flow of saline was observed during testing, the catheter performed as intended.During further functional testing, the returned catheter was connected to a known good suk and ran on the thermogard console system, running in the max warming mode with a target temperature at 37°c for 60 minutes and running in the max cooling mode with a target temperature at 35°c for 60 minutes.The balloons were properly warming during the warming mode and cooling during the cooling mode.No leak, no damage was found on the catheter, and the catheter performed as intended.The suk red pinwheel and the pump roller were rotating as normal and the flow of saline was observed during testing, the catheter performed as intended.

During patient treatment for fever management, the solex 7 catheter (lot # 172888) was inserted into the internal right jugular vein.The insertion was smooth from the first attempt.After 5 hours of ivtm therapy, the patient was not achieving the target temperature of 33°c.The nurse noted that the flow indicator of the start-up kit (suk) was spinning, however, the patient's temperature was still at 37,8°c.A new icy catheter was placed to continue therapy utilizing the same suk.No alarm on the thermogard system and no leakage of saline fluid was observed.The patient reached the target temperature.No injury or adverse impact was reported.The patient is stable.
