Abstract
A system, method and device for monitoring the condition of an internal organ, such as a brain, by providing an internal electrode. The internal electrode is operatively connected to at least one surface, external, electrode, and a system handler. A signal is generated between the electrodes such that the electrical properties, including conductivity and impedance among others, can be measured at and across the electrodes. The electrode arrangement allows for continuous monitoring of an internal organ and, where desired, mapping of the electrical properties thereof. The system obtains pressure readings, nodal conductivity and/or electrode impedance to monitor, map and report the condition of the internal organ. A correlation procedure is provided for generating a graphical representation of the condition of an internal organ from the gathered data. A medical treatment method is also provided for monitoring the status of the brain, and includes providing an internal electrode for measuring electrical properties of the internal organ.
