This report is being sent as follow-up no.1 to update section d9, section h3, and to provide the completed investigation results.The actual device has been returned for evaluation.One tr band and inflator were returned to terumo medical corporation for assessment.The sample was subject to visual analysis.No damage or deformities were noted on the inflator or band.There is 14ml left in the balloon assembly.The sample was subject to functional testing.The inflator tip was inserted into the check valve to check the seal.There were no issues with inserting or connecting the inflator to the check valve.The inflator was used to inflate the tr band.There were no issues inflating the tr band with the returned inflator.The complaint cannot be confirmed for inflation difficulties because the failure mode could not be replicated, and the inflator was able to inflate and deflate the band without issue.The exact root cause cannot be determined.It is possible the inflator tip was not fully inserted into the check valve initially, leading to insufficient inflation.Review of device history record (dhr) cannot be completed due to the unknown lot number.Currently no action is recommended since this risk evaluation is within the predetermined limits in the design failure mode & effects analysis (dfmea).
