Abstract

The current methodology for placing intracranial electrodes is highly invasive and requires a surgical window through the scalp, skull, and the dura. EEG’s recorded from the surface of the scalp are often not sensitive enough to capture valuable information. A less invasive alternative of measuring EEG and CSD would improve the care of patients, especially those with epilepsy. Our team’s goal is to create an implantable, non-disruptive device that is placed in the middle meningeal artery of the dura mater for the recording of seizure and CSD activity as it pertains to epileptic patients. The neuroendovascular field is estimated at $3.06 billion and has a compound annual growth rate of 7.7%. Our current design involves a guidewire and catheter to be led from the superficial temporal artery, to the maxillary artery, then enter the middle meningeal artery where a stent-electrode device will be implanted. The endo-lectrode will be far less disruptive while still providing valuable feedback from the dural artery. The endo-lectrode would be classified as a Class II medical device by the FDA.
