Abstract: Systems and methods for high-bandwidth, minimally invasive brain-computer interfaces (BCIs) are disclosed. The BCIs are configured for deployment and operation in conjunction with a comprehensive interventional electrophysiology procedural suite. Three primary methods of minimally invasive electrode array delivery are disclosed: (1) cortical surface delivery, (2) ventricular delivery, and (3) endovascular delivery. Additionally, systems and methods for interacting with such high-bandwidth electrode arrays are discussed, including real-time imaging, signal processing, and neural decoding. Systems and methods for architectures for accelerating the underlying computational processes (such as graphics processing units or tensor processing units) are also discussed. Multiple applications of BCIs are discussed, with emphasis on restoration, rehabilitation, and augmentation of neurologic function.

Abstract: The present disclosure relates to an array of electrodes and integrated electronics on a flexible scaffolding, with the ability to collapse into an axial configuration suitable for deploying through a narrow cylindrical channel. The electrode arrays can be placed into the ventricular system of the brain, blood vessels of the brain, and/or into other body cavities, constituting a minimally invasive platform for precise spatial and temporal localization of electrical activity within the brain and/or body, and precise electrical stimulation of tissue, to diagnose and restore function in conditions caused by abnormal electrical activity in the brain, nervous system, and/or elsewhere in the body.
