Abstract: A stent for insertion into an intracranial blood vessel of the cerebral venous sinus system includes a proximal end, a distal end, a body between the proximal end and the distal end, the body comprising a plurality of wires in a closed pattern, wherein the stent is configured for insertion into an intracranial blood vessel of the cerebral venous sinus system. The stent is further capable of being repositioned, retrieved/re-sheathed, and removed for more precise delivery.

Abstract: The present disclosure 1s 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: Described herein are systems and methods for deploying and recording electrophysiologic signals from electrode arrays located within the dura mater of the brain. The dura matter includes layers of connective tissue, or membrane, that surround the brain and spinal cord. The present disclosure relates to an endovascular electrode system deployed within the blood vessels located between layers of the dura mater, including, for example, the middle meningeal artery and its branches.
