Abstract: Apparatus for supplying electric energy to biological tissue with a view to supporting different physiological processes, including different phases of healing, growth, modification og pathological states, for example deterioration in blood flow, chronic pain, fluid accumulation in tissue etc., and similarly with a view to influencing viability conditions of, for instance, tumor tissue, the apparatus essentially comprising at least two electrodes connected to a voltage source. One electrode is adapted to be disposed in or on the biological tissue which is to be supported in its physiological or pathophysiological cycle, and the other electrode is adapted to be disposed in spaced-apart relationship from the biological tissue in such a position that electrically conducting circuits exist between the electrodes, the voltage source being arrnaged, via said electrodes, to supply current through the biological tissue.
