Electrochemical Treatment of Biological Processes    

Techniques and devices for electrical, chemical, electrochemical, and/or photochemical control of biological and biotechnological processes, e.g., treatment of cancer, benign tumors, etc.


The issued patents describe electrochemical techniques and devices to treat in situ a tissue, and specifically a malignant tumor, in order to destroy it with a minimal damage to the healthy tissues. The devices use at least one working electrode and one counter electrode placed in the vicinity of the tissue being treated and a control unit which regulates the applied voltage. The resulting electrochemical reactions yield various reaction products, some of them being cytotoxic agents destructive of cancer cells. The feedback mechanism optimizes the yields of those cytotoxic agents based on sensors measuring conditions prevailing in the tissue being treated. By an appropriate choice of signal parameters, the process can result in apoptosis (programmed cell death) rather than in tissue necrosis.

For a combined electrochemical and chemotherapy approach, hollow electrodes with multiple ports connected to a chemotherapy source can be used for in situ delivery of drugs or medication. Similar electrodes with internal fiber optics coupled to a light source can be used for photochemically activated drugs. Several other approaches, utilizing properties of the material of the electrodes to create cytotoxic agents, are also claimed.

In the pending patent application (CIP) the disclosure defines electronic delivery systems and methods with feedback, incorporating the electrochemical treatment of tissues described in the three issued patents, as well as methods for diagnosis and treatment.

Primary Application of the Technology

-Electrochemical treatment to destroy unwanted tissue, e.g., benign tumor
-Electrical stimulation
-Electrodes, e.g., for combined electrical or electrochemical treatment and in situ drug delivery
-Medical devices
-Control systems
