Tw # (b)(4).The device was returned to the factory for evaluation on 12/21/2023.An investigation was conducted on 01/02/2024.A visual inspection was conducted.Signs of clinical use and evidence of blood and charred material were observed on the device.The heater wire and clear silicone insulation of the jaws were observed to be intact with no visual defects.An electrical evaluation was conducted.A pre-cautery test was performed per the instruction for use (ifu) with a reference cable, adapter, and reference power supply vh-3010 at level 3.0.The device passed the pre-cautery test.It produced visible steam and heat during ten (10) 3-second activations and shut off when the toggle was released with no excessive smoke observed.A tone was audible from the power supply upon activation.To evaluate the safety shut down system, a polyfuse activation test was performed 5 times over 10 minutes.The device shut off after the period of sustained activation and reactivated after the 10-second cooling period with no incident each time.The jaws were gently cleaned of debris and char with a saline and gauze pad as indicated in the direction for use (cv000008979).An activation and transection capability test was performed over four (4) repetitions using "max life test method stm2048073 rev aa.The device successfully transected tissue four (4) times.A temperature and resistance test was conducted to evaluate the device function per hemopro 2 final test 90523436 rev w.The resistance value was measured at.688 ohms which is within specification.The device passed the temperature measurements test.The displayed temperature increased and turned green within the 2 second specified timeframe.The displayed temperature decreased once the toggle swivel was released.Based on the returned condition of the device, the reported failure "electrical/electronic property problem" was not confirmed.The lot # 3000346932 history record review was completed.There were no ncmrs, rework, or deviations documented for the reported lot number.Based on the dhr/lhr review results, it was determined that there is no relation between the batch manufacturing process and the reported failure.
