ABSTRACT:
An apparatus for the in situ generation of an electrical current in a biological environment characterized by including an electrolytic fluid. The apparatus comprises first and second electrodes of differing electrochemical potentials separated by an insulator. The apparatus is adapted to be implanted in the environment. The presence of the electrolytic fluid and formation of a current path by hyperplastic cells bridging the electrodes enables electrolysis to occur and a direct current to pass through the current path to impede hyperplastic cell growth.
