The AURAGEN™ Cortical Surface Electrodes are designed for intraoperative monitoring of cortical electrical activity in order to define the location of epileptogenic foci. They are placed on the exposed cortical surface or inserted into the subdural space to contact the cortical surface. Cortical Electrodes are available with platinum contacts and vary in size according to the number of contacts. The type of cortical electrode used is dependent on the procedure and the size of area being tested.
A sterile, invasive, electrical conductor that is temporarily placed (< 30 days) on the surface of the brain to stimulate the brain or to record the brain's electrical activity (with more precise localization than a scalp electrode). It is typically a series of discs mounted in thin plastic strips, or in a square/rectangular grid to cover larger surface areas. The implanted device, also known as a subdural electrode, is connected to recording, monitoring, or stimulation/response devices [e.g., electroencephalograph (EEG), evoked-potential recorder, stimulator]. This is a single-use device.
