The present disclosure 1s directed to systems and methods for endovascular electroencephalography (EEG) and electrocorticography (ECoG) systems. In some embodiments, the disclosed systems include electrode arrays that are configured to record and/or stimulate brain tissue via placement within blood vessels of the brain. Venous and arterial EEG and ECoG electrodes, ambulatory EEG and ECoG systems, and transcutaneous access and signal control systems for general and ambulatory endovascular electroencephalography (EEG) and electrocorticography (ECoG), as well as endovascular neural stimulating electrodes are discussed.

Described herein is a cleaning apparatus (10) for a medical device (12) having one or more internal channels. Further described is a method for cleaning the medical device using the cleaning apparatus. The cleaning apparatus includes at least two cleaning pumps (20) adapted to pump a viscoelastic liquid (22), each cleaning pump having individual flow control. Each cleaning pump is also fluidly connectable to one or more of the internal channels to allow the viscoelastic liquid to be pumped therethrough thereby removing contaminants.

An analyte measurement device including an analyte sensor configured to measure an analyte level, the analyte sensor including a tail portion for subcutaneous placement, the tail portion having an analyte-responsive enzyme disposed thereon; an applicator for delivery of the analyte sensor, the applicator having a housing defining a hermetically-sealed chamber, the tail portion disposed within the chamber prior to subcutaneous placement; and a scavenger material disposed within the chamber, the scavenger material comprising at least one of activated carbon, molecular sieve, and silica gel and configured to adsorb at least one substance within the chamber. A method of packaging an analyte sensor is also disclosed.

Apparatus for obtaining polarized imagery using a portable device, comprising a light source, a first polarizing filter configured to cover the light source, a second polarizing filter configured to cover the lens of a mobile device's built-in camera, one or more housing to contain the light source and filters, and couplers attached to the housings for coupling the housings to the mobile device. When the housing is coupled to the mobile device and the camera is operated, light from the light source passes through the first polarizing filter, then passes as polarized light through an illuminating path to illuminate an object being imaged. Then light from the illuminated object passes through an optical path, through the second polarizing filter to the camera lens. In embodiments, the axis of polarization of at least one of the polarizing filters can be modified to allow for cross, parallel and variable polarized imaging.

A method of managing a disease and an apparatus performing the same are provided. The method of managing livestock disease includes receiving biometric information of livestock from a biosensor capsule settled in a body of the livestock, detecting a singular point deviating from a reference value, based on the biometric information, monitoring a health state by increasing a disease probability of the livestock when the singular point is detected, and detecting a disease by determining an abnormality in the health state of the livestock when the disease probability of the livestock is a first threshold value or more. An animal subject suspected of reproductive disorders (ovarian cyst) may be rapidly detected, and intensive care (veterinary examination and hormone prescription) may be provided to the farm, thereby increasing productivity of the farm.
