Zusammenfassung:Various embodiments set forth medical devices. In some embodiments, the medical device includes an impedance bridge, an instrument head that includes one or more electrode pairs and a calibration impedance, and one or more wire pairs that couple the impedance bridge to the one or more electrode pairs and the calibration impedance. The disclosed medical devices compensate for impedance caused by extraneous factors arising from manufacturing and materials variances while measuring the impedance of tissue.
