Event or Problem Description
An error message was received stating the output current may not be deliverable due to impedance or battery voltage.The message was seen when the patient's generator was being programmed back on after being disabled.The vns was disabled due to testing being done on the patient's other implanted device.Information was received stating the programming system was using 1.6 software.The message was noted to resolve by turning off the tablet and re-interrogating or running system diagnostics.Internal testing and data review identified that false low output current messages can occur when m3000 v1.6 software programs a m103-106 generator after a specific programming sequence occurs.When m3000 v1.6 tablets initiate a programming session with a m103-106 generator, where its output current is programmed off (0 ma), and then the output current is programmed back on to ma, a low output current message would be seen when an in-session interrogation is performed.This would persist upon multiple in-session interrogations and if diagnostics weren't performed during the session, show on the session report.Running system diagnostics or ending and restarting the session will confirm functionality of the device, and resolve the ¿output current low¿ error message.The low output current messages in these cases are false and do not impact generator function.Based on the reported programming sequence that occurred that day, it was consistent with the false low output current mechanism described above.Therefore, the patient's generator is expected to be able to deliver therapy as programmed.No further relevant information has been received to date.
