Abstract
A technique and apparatus therefor adapted to treat in situ a malignant tumor, use being made of a working electrode and a counterelectrode implanted in the tumor at spaced positions. Applied across the electrodes is a voltage causing a direct current to flow through the tumor producing an electrochemical reaction yielding multiple reaction products, some of which are cytotoxic agents destructive of cancer cells. Coupled to the electrodes is a control unit which acts to regulate the voltage applied thereto so as to optimize the yield of those cytotoxic agents having the greatest efficacy.
