The invention comprises a system for treating a medical disorder using transcutaneous electrical stimulation. The system includes an apparatus that supplies voltage to one or more glass electrodes that is shaped to treat a particular tissue or disorder and that is applied to an affected area of the patient's body. Voltage is applied in a range of about 500-2000 volts and a constant frequency in a range of about 10-100 kHz. The electrode may also be used to sterilize the surface of a tissue through the production of ozone. The system may be used to treat a variety of medical disorders including edema and dermatological, neurological, intestinal, vascular, and orthopedic disorders. In addition, the system may be used to improve drug delivery to specific sites by locally increasing blood circulation.
