Disclosed herein are devices, methods, and systems for monitoring the position of a subjects head and/or provide instruction to bring the subject's head into a desired position, to perform a desired movement, or a series of head positions and/or movements.

A cap promoting hair growth is provided. In one embodiment, the cap covers the user's scalp while the hair growth is promoted by the vibration of micro-needle massage pad along with the illumination of laser beam with the growth factor applied to the user's scalp.

A head worn device for treating neurogenerative diseases. The head worn device has LEDs mounted to the device. Two printed circuit boards (PCB) are also mounted on the head worn device. Each PCB has a microprocessor and a battery in electrical communication. Each PCB controls a speaker for emitting audio and a vibrating device for emitting a vibration. The LEDs, speaker and vibrating device are in electrical communication with the microprocessor. The microprocessor is programmed to control the LEDs, the speaker and the vibrating device so that each operate at a regulated frequency so that generated light, sound and vibration travel to the user's brain for medical treatment.

Device for shave-free trans-cranial focused ultrasound (FUS) treatment and method for using same, the device including a scalp cover having a first inlet configured to allow supply of a gas into the scalp cover, and an outlet configured to allow outflow of ambient air contained within the scalp cover when the gas is being supplied, such that the ambient air contained within the scalp cover is replaced by the supplied gas.

Methods and apparatuses for improving sleep by transdermal electrical stimulation (TES). In general, described herein are methods for applying TES to a subject, and particularly the subject's head (e.g., temple/forehead region) and/or neck with an TES waveform adapted to improve sleep, including reducing sleep onset (falling to sleep) more quickly and/or lengthening the duration of sleep. TES waveform(s) particularly well suited to enhancing sleep are also described herein.

Device for shave-free trans-cranial focused ultrasound (FUS) treatment and method for using same, the device including a scalp cover having a first inlet configured to allow supply of a gas into the scalp cover, and an outlet configured to allow outflow of ambient air contained within the scalp cover when the gas is being supplied, such that the ambient air contained within the scalp cover is replaced by the supplied gas.

A method is provided and may include accessing a terminal branch of an ophthalmic artery through a skin of a head of a subject via a first device, positioning at least one of the first device or a second device within the ophthalmic artery of the subject, and performing an atherectomy of the ophthalmic artery or a junction between the ophthalmic artery and an internal carotid artery of the subject, using the at least one of the first device or the second device, so as to treat a blockage, a stenosis, a lesion, plaque, or other physiology in the ophthalmic artery or the junction between the ophthalmic artery and the internal carotid artery of the subject.

An ultra-low field pre-pulse Magnetic Resonance Imaging (PMRI) system for a head includes RF coils defining a bore for head access, a pre-pulse coil outside the RF coils, and a coil assembly including a main magnetic field coil and gradient coils outside the pre-pulse coil. The PMRI system includes a first cylindrical shield concentric with the RF coils and made from conductive materials. The first cylindrical shield partially encloses the RF coils and inside the pre-pulse coil for shielding the RF coils from environmental electromagnetic disturbances.

A respiratory mask can have a frame supporting a sealing arrangement. Various features of the frame and sealing arrangement can improve comfort and reduce the occurrence of pressure sores. The frame can include cheek supports that have a large surface area configured to spread loads over a greater area of the patient's face and therefore reduce the forces applied to the face and the occurrence of point loads. The seal can have a main body that includes a spring with a silicone skin, wherein the spring applies a substantially constant force to the face and/or nares of the patient.

Methods, systems and devices for treating headaches, including migraines. In some variations these methods may include enhancing sleep, including enhancing the quality of sleep, reducing sleep onset time, increasing total sleep time, treating insomnia, and/or treating other neurological disorders by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep.
