There was no patient involvement.Livanova deutschland manufactures the centrifugal pump system with tubing clamp.The incident occurred in (b)(6).A review of the dhr could not identify any deviations or nonconformities relevant to the issue.The scp panel was requested for further investigation.A visual inspection, a functional test and an hardware analysis were performed without detecting deviations: the unit worked as expected and within specification.No hardware failures were detected.Based on all the above facts, it cannot be ruled out that an intermittent connection between the motor control board and the hall sensor / pump control panel, contributed to the reported malfunction.It is likely that some mechanical change like temperature, vibration and / or physical stress of the panel led to the intermittent connections.
