System and method for characterization of an organic medium surrounding an electrode

A system for characterization of an organic medium surrounding an electrode, comprising:

• two or more electrodes, wherein at least one electrode of the two or more electrodes is configured to be insertable in tissue;
• and
• an analysis unit connectable to the two or more electrodes and configured to apply a measurement signal to the two or more electrodes, wherein the analysis unit is further configured to determine an impedance between the two or more electrodes based on the measurement signal and characterize the organic medium surrounding the at least one electrode based on an amplitude and/or phase of the impedance;
• and/or wherein the analysis unit is configured to apply a current pulse to at least one electrode and wherein the analysis unit is further configured to characterize the organic medium surrounding the at least one electrode based on the morphology of the applied current pulse.
