Abstract: The present disclosure is 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.

Abstract: The devices and methods described below provide for more convenient stereo-electro-encephalography, which may allow the patient to move freely during the days-long monitoring period. The system includes a number of depth SEEG electrodes. In one version of the system, each SEEG electrodes are wirelessly connected to an EEG console, through a subcutaneous electrode which is connected to the SEEG electrode through a conductor. The subcutaneous electrode is in turn wirelessly connected to a supra-cutaneous appliance operable to obtain SEEG signals, generated by the SEEG electrode, through the subcutaneous electrode. The method of use entails implantation of the depth SEEG electrodes deep in the brain, implantation of the subcutaneous electrodes under the scalp. The patient need not be physically connected to a console or control system, and may be ambulatory for the SEEG protocol period.

Abstract: Flexible, insertable, transparent microelectrode arrays that allow integration of electrophysiological recordings with any optical imaging or stimulation technology are disclosed. In some embodiments of the disclosed technology, a microelectrode array includes a flexible substrate layer including a shank member extending in a first direction and a tapered tip at an end of the shank member, and a plurality of electrode wires arranged in the first direction on the flexible substrate layer, wherein the plurality of electrode wires includes adjacent electrode wires having different lengths from each other such that an electrode wire arranged closer to a centerline of the flexible substrate layer is longer than an adjacent electrode arranged further away from the centerline of the flexible substrate.

Abstract: Intraoral electronic sensing for health monitoring is disclosed. Wireless connectivity is provided between a processor and a wireless transmitting device. The wireless transmitting device is embedded in an intraoral sensing interface for use in a person. Sensors are coupled to the wireless transmitting device, wherein the sensors are attached to the intraoral sensing interface. The sensors include a photoplethysmography (PPG) sensor to detect cardiac activity, a breathing sensor to detect pulmonary function, an inertial measurement unit (IMU) sensor to detect three-dimensional motion, and a temperature sensor to monitor body temperature. Further sensors include an electroencephalogram sensor to detect brain activity. Health data about the person is provided to a receiving device, based on data from one or more of the PPG sensor, the breathing sensor, the IMU sensor, and the temperature sensor. The health data is provided using the wireless connectivity.
