It was reported that the physician ran diagnostics on the patient's vns and it was stated that it looked like there were lead issues.High impedance was observed on the patient's m102 vns generator when using the physician's m3000 v1.5.2.1 vns programming system with a dcdc code of 4.However, diagnostics with a motion vns programming tablet revealed that the high impedance reading was false.This issue was duplicated with in-house testing.For model 102/102r generators programmed to output currents greater than 1.00 ma , it was observed that system diagnostics using m3000 v1.0 and m250 software would display ok lead impedance while system diagnostics using m3000 v1.5 software would display a false high impedance.It was determined that the cause of this false high impedance message was a software error on m3000 v1.5.2.1 software; when system diagnostics were performed by the user with m3000 v1.5.2.1 software on m102/102r generators (normal mode output current;0 ma), normal mode diagnostics would actually be performed instead.The execution of normal diagnostics instead of system diagnostics is not apparent to the user, and the returned dcdc code was being compared against system diagnostic thresholds.No additional relevant information has been received to date.
