Publication number: 20220117536Abstract: An electrode carrier system includes one or more electrode assemblies having an electrode body. One or more tubular members extend from the electrode body and define a lumen terminating in a distal opening. The electrode assemblies carry a reservoir containing a conductive fluid or gel. The reservoir is in fluid communication with the lumens in the tubular members, and the electrode assemblies are typically supported on a backing which may optionally be configured as a headband. Systems are for tracking patient movement may be used in combination with the electrode carrier system.Type: ApplicationFiled: December 28, 2021Publication date: April 21, 2022Inventors: Josef PARVIZI, Xingjuan CHAO, Bradley G. BACHELDER, Raymond WOO, Mathew A. HERRON, Vahid SAADAT, Alexander M. GRANT, Jianchun YI

Publication number: 20220031248Abstract: Systems, devices, and methods are provided to assess connection quality between the electrodes of a bioelectrical signal measurement and/or electrical stimulation device and the tissue, typically skin, of the subject. A test signal is provided to a first electrode, voltage differences between the first electrode and additional electrodes are determined, an impedance of the first electrode is determined based on the voltages differences, and the determined impedance indicates connection quality. This process is typically repeated for all of the electrodes to determine connection quality. The user or subject can be alerted if the connection quality is poor, and the bioelectrical signal that is recorded can be provided with data points indicating connection quality during the signal recording.Type: ApplicationFiled: March 16, 2021Publication date: February 3, 2022Inventors: Alexander M. GRANT, Jianchun YI, Bradley G. BACHELDER, Raymond WOO, Josef PARVIZI, Xingjuan CHAO

Publication number: 20210085235Abstract: The present disclosure provides systems and methods for seizure detection. The method for seizure detection may include receiving a plurality of electroencephalography (EEG) signals over a plurality of channels for a subject, preprocessing the plurality of EEG signals by segmenting the plurality of EEG signals for each channel into a plurality of temporal data segments, extracting a plurality of features from each temporal data segment for each channel, and applying a machine learning algorithm to the plurality of features to perform a seizure binary classification for each temporal data segment for each channel. A control policy may be employed to determine a seizure burden on the aggregated seizure binary classifications. When the seizure burden is equal to or exceeds a threshold, a notification may be generated. The notification may be usable by a healthcare practitioner to assess whether the subject may be at risk of having a seizure.Type: ApplicationFiled: July 8, 2020Publication date: March 25, 2021Inventors: Baharan Kamousi, Mehdi Hajinoroozi, Suganya Karunakaran, Alexander M.
