Abstract
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.
Claims14
A method for electrically interacting with a neural tissue using an electrode array located within a ventricular compartment of a brain, the method comprising:
- selecting a portion of neural tissue for electrical interaction;
- accessing previously stored registration information regarding a location of the electrode array within the ventricular compartment of the brain;
- selecting one or more electrodes in the electrode array for electrical interaction based on the registration information;
- and
- interacting with the neural tissue with the selected electrodes, wherein interacting with the neural tissue comprises at least one of forming an electrical field beam distributed in a three-dimensional space using the selected electrodes and localizing electrical activity in the brain using the selected electrodes distributed in the three-dimensional space.
