Dream stage enhancement uses a headband with EEG-EOG sensors, onboard processors, memory, coarse and fine time REM waveform detection modules, LEDs and an audio playback unit. After normalization to the user's EEG waveforms, the user's EEG-EOG signals are processed, REM and NREM stages detected and light, sound or AV stimuli are presented to the user based upon user-supplied light-sound-AV stimuli commands. To provide a reality check control (RCC), the head unit has a user actuatable RC interface whereby during sleep, RC stimuli are presented when the user depresses the RCC control which plays back the user supplied stimulus. In a learning mode, the user selects Recall or No Recall (NR) after the sleep period. If NR, then the system changes the color of light stimuli, light intensity, flash, audio sound type, audio intensity, and AV. If Recall the user supplied stimuli commands are carried out.

Methods and devices quickly and accurately locate the sphenopalatine ganglion (SPG) while performing a sphenopalatine ganglion block procedure that introduces a medication to the SPG. The methods and devices also prevent the medication applied to the SPG from flowing down a patient's throat during the procedure.

Methods, systems and devices for 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. Described herein are thermal applicators that include phase change materials and/or evaporative cooling, as well as headgear for securing the applicators comfortably against the appropriate region of the user's head.

Devices and methods for wound treatment are disclosed. A chamber may define a treatment space having an interior engineered surface including a plurality of structures configured to provide pathways for the distribution of negative pressure and to exert mechanical stress on a wound. One or more tubes may be in fluid communication with the treatment space to facilitate the application of negative pressure, the introduction of therapeutic agents, and the removal of wound material. Therapeutic agents may be formulated with a gel, for example, a hydrogel, a hydrocolloid, alginate, methyl cellulose, gelatin or any other gels for sustained-release and enhanced usability. A wound fluid collection device including an absorbable material may interface with the wound treatment device to facilitate the collection and disposal of wound material.

In one aspect, a computer-implemented method of adapting a sensory datastream is provided. The method includes obtaining a raw sensory datastream from a source, wherein the raw sensory datastream comprises input for a sensory actuator of a user device. The method includes obtaining state information, wherein the state information comprises information indicating a first state of a user. The method includes predicting, using a machine learning model, a desired second state of the user based on the obtained state information. The method includes determining an action to adapt the raw sensory datastream based on the desired second state of the user. The method includes adapting the raw sensory datastream in accordance with the determined action and the first state of the user to create a processed sensory datastream. The method includes providing the processed sensory datastream to the sensory actuator of the user device.

Methods and devices to quickly and accurately apply medication to a paranasal sinus are disclosed. Additionally, the methods and devices prevent the medication applied to a paranasal sinus from flowing down a patient's throat by expanding, using an inflation lumen of a device, an expandable member of the device adjacent to the patient's choana.

A full face mask made of cloth having a nasal portion, an oral portion and transition portions is disclosed. The nasal and oral portions are made of a cloth that is impermeable to air and have nasal and oral interfaces on them to facilitate a seal with a user's face. The transition portions have easy removal clips for the lower headgear straps and sealing assistance members for better sealing.

A dream stimulator may include a substrate and a plurality of electrodes positioned along a first side of the substrate. The stimulator also may include a stimulator coupled to the substrate. At least one lead may couple the plurality of electrodes to the stimulator. Additionally, a band may be positioned along a second side of the substrate and about each of the plurality of electrodes.

Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.

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.
