H3, h6: the real intelligence foot pedal, part number rob10026, serial number (b)(6), used for treatment was not returned for evaluation, therefore a device analysis was unable to be performed.The software files were downloaded from the device and provided for investigation.When the foot pedal is connected a voltage spike is generated, the log files show a voltage above the normal which results in a error.The symptoms relating to the problem can be compared to bug 1973.A complaint history review for similar reported/confirmed complaints has identified prior events.A review of manufacturing records indicate the device met all specifications upon release into distribution.The real intelligence cori for knee arthroplasty user manual (500230 rev d) provides guidelines for recovering to a fully manual procedure in the "recovery procedure guidelines, appendix d".The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still within the product risk profile.A historical review concluded that no prior escalation actions are applicable to the scope of the reported complaint.The most likely cause of this event is associated with a software bug.Based on the investigation, the need for a corrective action is not recommended or required at this time.Should any additional information be received the complaint will be reopened.The failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.
