Northgate technologies, inc.(nti) received a device for evaluation with an alleged complaint of "one of the ports is arcing electrical.", the complaint was coded by the distributor as no known impact or consequence to patient.Initial evaluation of the device indicated, the unit had signs of fluid invasion within the front panel and the unit was received with the fuses removed from the power module.The nature of the fluid contamination could not be determined.When the unit was powered on with new fuses, the display, spark gaps within the unit, and hv trigger board led were flashing involuntarily without connection to any external sources attached to the unit which is abnormal (the device is designed such that the spark gaps should only activate upon activation of the attached foot pedal accessory).There was no actual arcing or firing noted within the unit or outside the unit however given that the spark gaps were observed to be flashing this indicates that power could / was being transferred to the bulkhead connector without any activation.The device is designed with a bulkhead connector which is connected to a reusable extender cable which is then connected to disposable bipolar ehl probe to allow the energy propagation from the ehl generator to the tip of the probe.An extender cable nor probe were connected to the bulkhead while the display and spark gaps were flashing independently so transference of energy in this state was not confirmed.The hv trigger board seems to have been damaged with the fluid invasion.
