Event Description

Livanova received report that dashes were displayed in the rpm menu with/without rotating the speed knob of a s5 mast roller pump.Reportedly, the pump was not spinning when rotating the set knob.The issue occurred during priming.There was no patient involvement.

Manufacturer Narrative

There was no patient involvement.Livanova (b)(4) manufactures the s5 mast roller pump.The incident occurred in (b)(6).The motor controller board was suspected to be defective.If any additional information pertinent to the reported event is received, it will be provided in a supplemental report.

Manufacturer Narrative

Through follow-up communication livanova learned that the distributor engineer troubleshooted the issue at the customer site without detecting deviations.The unit was found to be working according to specifications.In addition, it was learned that the issue occurred only once and the pump was put back in service after having been checked by the distributor engineer.No further issues occurred.The serial read-out of the involved pump (real time device parameters and setting recording file) was analyzed.Results confirmed the reported event.An error code was found to be stored in the pump micro-controller.Based on the investigation performed for similar cases, the most likely root causes of the identified error code are: - defective resolver located in the pump head - defective motor control board taking into account that no hardware malfunctions were detected during the checks performed by the distributor engineer on site, that no components were replaced and that the issue did not recur, it is reasonable to assess that the reported event was caused by a temporary loose connection between the resolver and the motor control board, re-established with the restart of the pump.
