Systems and methods for high-bandwidth minimally invasive brain-computer interfaces

A system for minimally invasively interfacing with a cortical surface of a patient, the system comprising:

• a stent-based electrode array configured to be minimally invasively inserted to a target area along the cortical surface in a subdural space of the patient;
• a delivery catheter configured to deploy the electrode array to the target area;
• one or more processors;
• and
• a non-transitory, computer-readable medium storing instructions that, when executed, cause the one or more processors to:
• receive a location of the electrode array as the electrode array is delivered via the delivery catheter along the cortical surface in the subdural space of the patient using an imaging modality, wherein the imaging modality comprises at least one of fluoroscopy, computed tomography (CT), or angiography,
• receive one or more signals of electrical activity via the electrode array along the cortical surface of the target area in the subdural space of the patient,
• decode the one or more signals to obtain measurements of the electrical activity, and
• display an image comprising electrophysiological information corresponding to the one or more signals, the image configured to confirm an anatomical location of the electrode array at the target area based on the measurements of the electrical activity.
