METHODS AND SYSTEMS FOR INTRAVENTRICULAR BRAIN STIMULATION
First Claim
1. A neuromodulation system configured to pass into, within, or through a ventricle in the brain, the system comprising:
- one or more passageways for fluid; and
an electrode or effector configured to modulate neural activity thereby modulating a neural state.

Abstract
The present application is directed to devices and methods that can treat dementia or other brain disorders via electrical stimulation. Embodiments disclosed herein utilize brain stimulation of brain areas involved in memory and cognition through an intraventricular approach. Brain stimulation is combined with CSF flow in an intraventricular electrode having one or more passageways to permit fluid to flow therethrough. For example, an intraventricular electrode shunt catheter can be safely placed in any part of the ventricular system and through any foramen or aqueduct of the ventricular system without fear of obstruction to CSF flow.
