Zusammenfassung:	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 is configured to control a power output of the segmentation device. The controller has a processing component, responsive to the sensors, configured to execute the following: (a) derive a power factor of power applied to the at least one electrode; and (b) responsive to the deriving a power factor, 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 the power factor. T is a threshold value.
