Abstract: A non-invasive electrical stimulator shapes an elongated electric field of effect that can be oriented parallel to a long nerve, such as a vagus nerve in a patient's neck, producing a desired physiological response in the patient. The stimulator comprises a source of electrical power, at least one electrode and a continuous electrically conducting medium in contact with the electrodes. The conducting medium is also in contact with an interface element that may conform to the contour of a target body surface of the patient when the interface element is applied to that surface. When the interface element is made of insulating (dielectric) material, and disclosed stimulation waveforms are used, the power source need not supply high voltage, in order to capacitively stimulate the target nerve.

Abstract: The present invention includes methods and devices for treating hypotension, such as in cases of shock, including septic shock, anaphylactic shock and hypovolemia. The method includes the step of applying at least one electrical impulse to at least one selected region of a parasympathetic nervous system of the patient. The electrical impulse is sufficient to modulate one or more nerves of the parasympathetic nervous system to increase the ratio of blood pressure to heart rate and relieve the condition and/or extend the patient's life.

Abstract: A non-invasive electrical stimulation device shapes an elongated electric field of effect that can be oriented parallel to a long nerve, such as a vagus nerve in a patient's neck, producing a desired physiological response in the patient. The stimulator comprises a source of electrical power, at least one electrode and a continuous electrically conducting medium in which the electrode(s) are in contact. The stimulation device is configured to produce a peak pulse voltage that is sufficient to produce a physiologically effective electric field in the vicinity of a target nerve, but not to substantially stimulate other nerves and muscles that lie between the vicinity of the target nerve and patient's skin. Current is passed through the electrodes in bursts of preferably five sinusoidal pulses, wherein each pulse within a burst has a duration of preferably 200 microseconds, and bursts repeat at preferably at 15-50 bursts per second.

Abstract: Non-invasive electrical nerve stimulation devices and magnetic stimulation devices are disclosed, along with methods of treating medical disorders using energy that is delivered noninvasively by such devices. The disorders comprise migraine and other primary headaches such as cluster headaches, including sinus symptoms that resemble an immune-mediated response (“sinus” headaches), irrespective of whether those symptoms arise from an allergy that is co-morbid with the headache. The disclosed methods may also be used to treat other disorders that may be co-morbid with migraine headaches, such as anxiety disorders. In preferred embodiments of the disclosed methods, one or both of the patient's vagus nerves are stimulated non-invasively. In other embodiments, parts of the sympathetic nervous system and/or the adrenal glands are stimulated.

Abstract: Methods and devices for treating anaphylaxis, anaphylactic shock, bronchial constriction, and/or asthma include providing an electrical impulse to a selected region of the vagus nerve of a patient suffering from anaphylaxis to block and/or modulate nerve signals that would regulate the function of, for example, myocardial tissue, vasodilation/constriction and/or pulmonary tissue.

Abstract: A novel non-invasive magnetic stimulator is used to modulate electrical activity of a patient's vagus nerve. Parameters of the stimulation are selected in such a way as to induce a state of euphoria in the patient. The methods and devices may be used for anesthesia, or to treat insomnia, depression, or premenstrual syndromes. They may be used as substitution withdrawal tools for individuals who otherwise would depend on substances and behaviors to achieve a euphoric state of mind, particularly individuals who abusively consume drugs, alcohol or food, or who exhibit behavioral disorders such as compulsive gambling. The devices and methods may also be used to prevent, manage, or relieve stress.

Abstract: Methods and devices are disclosed for the non-invasive treatment of neurodegenerative diseases through delivery of energy to target nervous tissue, particularly the vagus nerve. The devices include a magnetic stimulator having coils with toroidal windings, which are in contact with an electrically conducting medium that is adapted to conform to the contour of a target body surface of a patient. The coils induce an electric current and/or an electric field within the patient, thereby stimulating nerve fibers within the patient. The stimulation brings about reduction of neuroinflammation in patients suffering from conditions comprising Alzheimer's Disease, Parkinson's Disease, Multiple Sclerosis, postoperative cognitive dysfunction and postoperative delirium.

Abstract: Devices, systems and methods are disclosed for treating bronchial constriction related to asthma, anaphylaxis or chronic obstructive pulmonary disease. The treatment comprises transmitting impulses of energy non-invasively to selected nerve fibers that are responsible for smooth muscle dilation. The transmitted energy impulses, comprising magnetic and/or electrical, mechanical and/or acoustic, and optical and/or thermal energy, stimulate the selected nerve fibers.

Abstract: Devices and systems are disclosed for the non-invasive treatment of medical conditions through delivery of energy to target tissue, comprising a source of electrical power, a magnetically permeable toroidal core, and a coil that is wound around the core. The coil and core are embedded in a continuous electrically conducting medium, which is adapted to have a shape that conforms to the contour of an arbitrarily oriented target body surface of a patient. The conducting medium is applied to that surface by any of several disclosed methods, and the source of power supplies a pulse of electric charge to the coil, such that the coil induces an electric current and/or an electric field within the patient, thereby stimulating tissue and/or one or more nerve fibers within the patient. The invention shapes an elongated electric field of effect that can be oriented parallel to a long nerve. In one embodiment, the device comprises two toroidal cores that lie adjacent to one another.
