High-density Flexible μECoG for Epilepsy Surgery - A Single-Arm ECT

During resective epilepsy surgery, a sterile high-density flexible microelectrocorticography will be placed on the exposed cortical surface over the suspected epileptogenic zone and adjacent cortex. The array will be used for high-spatial-resolution intraoperative μECoG recording and real-time analysis of epileptiform activity, including interictal spikes, high-frequency oscillations, spatial discharge gradients, and propagation patterns. The intraoperative ECoG findings will be provided to the surgical team to assist in defining the epileptogenic zone and tailoring the extent of resection. The high-density μECoG is used for intraoperative recording only and will be removed before wound closure.
