Abstract
An implantable medical device comprises a signal generator for generating a current signal having a frequency in a frequency window slightly less than the β-dispersion frequency of a tissue and applying the signal over the tissue. A signal measurer measures the resulting voltage signal and an impedance parameter is calculated from the applied and measured signal by a parameter determiner. A status monitor monitors the permeability status of cell membranes in the tissue based on this impedance parameter.
