There was no patient involvement.Livanova (b)(4) manufactures the s5 roller pump.The incident occurred in (b)(6).The serial read out of the pump has been analyzed.The pump stop could be caused by the level alarm which occurred 2 minutes before the hand-cranking started or by the several cover stop alarms which occurred between the level stop and the hand cranking.Based on these results, it is reasonable to assume that the device was working according to specifications.If any additional information pertinent to the reported event is received, it will be provided in a supplemental report.
