1. A medical device comprising:

  • an impedance measurement circuit comprising at least three measurement electrodes, configured to interact in vivo with intracorporeal tissue of a patient said at least three measurement electrodes of said impedance measurement circuit being configurable into at least two different measurement electrode configurations;

    said impedance measurement circuit being configured to apply a measurement signal, selected from the group consisting of a measurement current and a measurement voltage, to each of said at least two different electrode configurations and to measure and calculate an impedance of the tissue therefrom, impedance measurement circuit being configured to measure said impedance of said tissue using each of said at least two different measurement electrode configurations and to calculate said impedance values from respective impedance measurements obtained with said at least three measurement electrodes in said at least two different measurement electrode configurations, respectively;

    a storage unit connected to said impedance measurement circuit in which a plurality of respective impedance values, respectively representing impedance measured over time by said impedance measurement circuit, are stored; and

    an analyzing unit, having access to said storage unit configured to calculate an amount of visceral fat in said tissue by comparing the respective impedance measurements obtained with said at least two electrode configurations to each other, wherein said at least two different measurement electrode configurations include one configuration wherein the impedance is essentially not influenced by visceral fat of said tissue.
