Abstract: Methods and devices are provided for the non-invasive treatment of diseases or disorders, such as Alzheimer's disease, Parkinson's disease, rheumatoid arthritis (RA), multiple sclerosis, postoperative cognitive dysfunction, or postoperative delirium. A method for comprises positioning an electrode in contact with an outer skin surface of a neck of the patient and transmitting, via the electrode, an electric current transcutaneously and non-invasively through the outer skin surface of the neck of the patient to generate an electrical impulse at or near a vagus nerve within the patient. The electrical impulse comprises bursts of 2 to 20 pulses with each of the bursts comprising a frequency from about 15 Hz to about 50 Hz and with each of the pulses comprising a duration from about 20 microseconds to about 1000 microseconds.

Abstract: Devices, systems and methods are disclosed that allow a patient to self-treat a medical condition, such as headache, by noninvasive stimulation of a nerve. A system comprises a stimulator having an interface configured to contact an outer skin surface of a patient and an energy source coupled to the interface. The energy source transmits an electrical impulse through the interface transcutaneously through the outer skin surface of the patient to a nerve of the patient such that the nerve is modulated. The system further comprises a mobile device coupled to the stimulator to transmit data to the stimulator. The data includes a therapy regimen to reduce one or more symptoms of a headache in the patient.

Abstract: A hair brush applicator for applying flowable hair care products such as hair conditioner and styling gel to the hair of a user. The hair brush applicator includes a hair brush with a handle portion and a head portion. The handle portion of the hair brush has a chamber therein. The head portion of the hair brush has a plurality of bristles outwardly extending from the front face of the hair brush. The bristles of the head portion comprise a plurality of narrow bristles and a plurality of wide bristles. Each of the wide bristles is tubular and has an open root coupled to the head portion and terminates at a closed tip. The hair brush has a passage therein fluidly connecting the chamber adjacent the neck portion to the open roots of the wide bristles. Each of the wide bristles has a plurality of lateral apertures positioned between the root and tip of the respective wide bristle. The hair brush has a rotatably mounted disk blocking the passage of the hair brush. The disk has a plurality of bores therethrough.
