(b)(4).The device was returned to the factory for evaluation.A visual inspection was conducted.Signs of clinical use and evidence of blood were observed on the tool jaws.Charred tissue was evident on the jaws.It was observed that a portion of the silicone insulation on the hot jaw was peeled and detached at the distal end, which left the metal part exposed.The detached portion of the insulation was not returned to the factory.The insulation that remained attached to the hot jaw looked cracked and charred due to its ash like appearance.The heater wire on the hot jaw was flexed but remained attached to the jaw.The insulation on the cold jaw appeared intact.An electrical evaluation was conducted.A pre-cautery test was performed per the instruction for use with a reference cable and reference power supply vh-3010 at level 2.5.The device passed the pre-cautery test; it produced visible steam and audible sound during several activations over a period of 10 minutes and shut off when the toggle was released.The pre-cautery test was repeated 10 times with no observed failure.The tool handle was opened to evaluate the internal components.No visible defects were observed to the toggle.Microscopic inspection showed no residue or contamination on the inner switch mechanism.Based on the returned condition of the device and the evaluation results, the reported failure "device remains activated" was not confirmed.The analyzed failures "thermal decomposition of device," "material twisted/bent" and "peeled" were all confirmed.
