During the visit on site, the serial readout (real time device parameters and setting recording file) of the pump was collected.The analysis of the serial read-out revealed that the error code 458 (timeout_motor) was stored on the date of the events.Based on the investigation performed for similar cases, the stored error codes can be due to (i) disconnection of the motor from the motor control board and/or (ii) defective motor and stage board (hmf) and, in particular, to its dc/dc converter.Field service technician dispatched to the facility solved the issue by replacing the hms board.Complaints database analysis revealed no similar event since unit installation in 2021.Based on the error message displayed, the analysis of log and the service activity, the most likely root cause is an hms board defective.The risk is in the acceptable region.No specific action was currently deemed necessary.Livanova will keep monitoring the market.This report was due on november 30, 2023; however, due to a network disruption at livanova, the ability to submit mdrs was lost on november 19, 2023, before this report was ready to submit.The report was prepared and submitted immediately following restoration of the livanova systems.
