A device for the transcutaneous electrical stimulation of the trigeminal nerve is provided. The device has an elongated symmetrical support with at least one electrode pair, and the support can be applied on a person's forehead in the supraorbital region to cover the afferent paths of the supratrochlear and supraorbital nerves of the ophthalmic branch of the trigeminal nerve. Each electrode pair contacts a self-adhesive conductive gel that at least partially covers one surface of the support for attaching the support to the forehead to be applied to two lateral zones with the exception of an insulating central zone. Each lateral zone has one electrode of the electrode pair, an electric circuit for supplying to the electrode pair electric pulses that have a predefined intensity, and a measurement means for measuring the intensity of the supplied pulses that is connected to the electric circuit.

Device for the transcutaneous electrical stimulation of the trigeminal nerve

The current invention concerns a system and a method for the acute non-invasive treatment of a migraine attack. The system comprises at least one skin electrode for placement on the forehead of a patient. The system is configured for providing consecutive biphasic electrical pulses via said at least one skin electrode to the supratrochlear and supraorbital nerves of the ophthalmic branch of the trigeminal nerve during a prolonged time span. Preferably, the time span is at least 10 minutes.

External trigeminal nerve stimulation for the acute non-invasive treatment of migraine attacks

An automated adaptive muscle stimulation system and method are disclosed. The stimulation system includes at least one electrode assembly adapted to deliver a muscle stimulation signal to the tissue of a user, a sensor system adapted to detect a muscle response, and an electrical stimulation device operably coupled to the at least on electrode assembly and the sensor system, the electrical stimulation device including a control system operable to automatically diagnose at least one characteristic of a muscle from the detected muscle response and adjust at least one parameter of the muscle stimulation signal in response thereto to deliver an adjusted muscle stimulation signal. A dual mode muscle stimulation system adapted to accept first and second data sets and provide first and second levels of treatment data is also disclosed.

The present invention provides a device for the transcutaneous electrical stimulation of the trigeminal nerve. The device comprises an elongated symmetrical support comprising at least one electrode pair, said support being suitable to be applied on the forehead of a person's face in the supraorbital region thereby covering the afferent paths of the supratrochlear and supraorbital nerves of the ophthalmic branch of the trigeminal nerve; each electrode pair being in contact with a self-adhesive conductive gel, said conductive gel covering at least partially one surface of the support for attaching said support to the forehead and being applied to two lateral zones with the exception of an insulating central zone, whereby each lateral zone comprises one electrode of the electrode pair; at least one electric circuit for supplying to the electrode pair electric pulses having a predefined intensity, and at least one measurement means for measuring the intensity of the supplied pulses, said measurement means being connected to the electric circuit.

The present invention provides a method for the treatment of consciousness disorder comprising the steps of positioning at least two electrodes on a patient's head such that the first electrode is positioned on the right supraorbicular cortex and the second electrode is positioned on the left dorso-lateral prefrontal cortex; connecting said electrodes to at least one source of electrical current; delivering direct current to the electrodes, and removing the electrodes from the patient's head after a time T; wherein steps a) to d) represent a treatment session and wherein at least one treatment session is is applied on the patient's head at least 2 days per week.

Method for the treatment of consciousness disorders

An electrode system for transcutaneous nerve and/or muscle stimulation that includes a pair of stimulating electrodes and a stimulation current generator for generating a nerve and/or muscle stimulation current between the stimulating electrodes. The system also includes a current-injecting electrode arranged in proximity to one of the stimulating electrodes, and an injection-current generator located in the area of the current-injecting electrode. The current-injecting electrode and the corresponding injection-current generator reduce, or even eliminate, undesirable sensations resulting from an excitation of subcutaneous receptors by the stimulation current.

Electrode system for transcutaneous nerve and/or muscle stimulation

The invention concerns a method for performing an electric inhibition of the facial muscles for purely aesthetic purposes, using a device comprising a support at the head of a user (), two contact electrodes (), an electronic circuit () for generating low-voltage electric pulses at said electrodes (), a direct current electric power supply () and means for fixing and locking () said components on the head. The invention is characterized in that it includes the following steps: placing the electrodes () on either side of the upper part of the nose, at the glabella; passing the electric pulses via the electrodes () through the pyramidal muscle of the nose so as to cause said pyramidal muscle of the nose to relax and hence its antagonist muscle, the forehead muscle and the double eyebrow muscle.

Apparatus for electro-inhibition of facial muscles

The present invention relates to a headband for use in neurostimulation made at least partly of elastic or stretch material comprising: a hole to be located directly on the rear part of the scalp of a user, said hole being sized to fit the inion or occipital protuberantia; at least two electrodes directly attached to the headband and positioned adjacent to and symmetric about said hole, designed so that to be applied on the right and left branch of the occipital nerve respectively, once the inion is put in correspondence with said hole by the user; a connector for connecting a wearable neurostimulator to the headband, said connector being located opposite to said hole, once the headband is worn by the user and means coupled to the elastic or stretch material for electrically connecting said connector and each of said electrodes.

The present invention relates to a method for inducing relaxation or sleep comprising the steps of:

Neurostimulation method to induce relaxation or sleep

A device is for the electrotherapeutic treatment of headaches such as tension headaches and migraines. An electrode support () has a shape and is size selected so as to allow, independently from the subject, the excitation of the afferent paths of the supratrochlear () and supraorbital () nerves of the ophthalmic branch () of the trigeminal nerve. An electrical circuit includes a programmable signal generator suitable for creating pulses of a duration of between 150 and 450 microseconds with a maximum increase in intensity of 0 to 20 milliamperes at a rate of less than or equal to 40 microamperes per second and with a step up in intensity not exceeding 50 microamperes.
