Abstract
A system and method for electrical stimulation of the human body, and in particular, to systems and methods for electrode systems and signal delivery used in electrical-stimulation treatment, testing and monitoring of vision problems of a patient, analyzing the results of the treatments, and monitoring to determine, for example, whether a medical treatment for the patient needs to be continued and/or altered, wherein the design and placement of the electrode systems and adjustment of signals delivered to the electrodes facilitate adjustment of the geometry of signal flow through the tissues of the patient.
Claims21
An apparatus comprising:
- an electrode system for use in electrical-stimulation treatment, testing and monitoring of vision problems of eyes of a patient, the electrode system including:
- one or more eyelid electrodes configured to be applied to one or more eyelids of the patient, and
- a plurality of skin-contact return-electrode areas on a single, unitary insulating polymer substrate, wherein the plurality of return-electrode areas is configured to be applied to a rear portion of the patient's head;
- and
- an electrical controller operatively coupled to the one or more eyelid electrodes and to the plurality of skin-contact return-electrode areas, and configured to control electrical currents applied through each one of the one or more eyelid electrodes and to the skin-contact return-electrode areas so as to selectively alter a geometry of electric fields through the eyes of the patient.
A method for treating eyes of a patient, the method comprising:
- providing an electrode system that includes:
- one or more eyelid electrodes, and
- a plurality of skin-contact return-electrode areas on a single, unitary insulating polymer substrate;
- applying the one or more eyelid electrodes to one or more eyelids of the patient;
- applying the plurality of skin-contact return-electrode areas to a rear portion of the patient's head;
- and
- controlling electrical currents applied through each of one of the one or more eyelid electrodes and to the plurality of skin-contact return-electrode areas in order to alter a geometry of electric fields through the eyes of the patient.
An apparatus comprising:
- an electrode system for use in electrical-stimulation treatment, testing and monitoring of vision problems of eyes of a patient, the electrode system including:
- one or more eyelid electrodes configured to be applied to one or more eyelids of the patient, and
- a plurality of skin-contact return-electrode areas on a single, unitary insulating polymer substrate, wherein the plurality of return-electrode areas is configured to be applied to a location on the patient's skin other than the one or more eyelids of the patient;
- and
- one or more electrical controllers operatively coupled to the one or more eyelid electrodes and to the plurality of skin-contact return-electrode areas, and configured to control electrical currents applied through each one of the one or more eyelid electrodes and to the skin-contact return-electrode areas so as to selectively alter a geometry of electric fields through the eyes of the patient.
