The present disclosure relates to a method of generating visual percepts using conformal electrode arrays. The electrode arrays can be placed into the ventricular system or cerebral venous sinuses, which function as minimally invasive techniques for precise spatial and temporal localization of electrical activity within the brain, and precise electrical stimulation of brain tissue, to diagnose and restore function in conditions caused by abnormal electrical activity in the brain. The disclosure further comprises a system for using these arrays to generate time-varying electric fields to stimulate the visual pathways of the brain, including the optic radiations and the occipital cortex, in ways that lead to visual perception.

Visual prosthesis employing ventricular or endovascular neural electrode arrays

The present disclosure relates to an array of electrodes 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, constituting a minimally invasive platform for precise spatial and temporal localization of electrical activity within the brain, and precise electrical stimulation of brain tissue, to diagnose and restore function in conditions caused by abnormal electrical activity in the brain.
