Abstract
A tissue segmentation device, controller, and methods therefore are disclosed. The device has an active electrode, a return electrode, a mechanical force application mechanism, voltage and current sensors, and a controller. The controller has a processing component, configured to assign a circuit status to a circuit comprising the at least one electrode. IF (PF≈0) and ((Vrms/Irms)≥T), THEN the circuit status is “open”. IF (PF≈0) and ((Vrms/Irms)<T), THEN the circuit status is “short”. PF is a power factor of power applied to the electrosurgical device. T is a threshold value.
