Brain-machine interface systems and methods
First Claim
1. A device for sensing the activity of neural tissue comprising:
- a catheter;
an electrode that is smaller than 5 micrometer in diameter, the electrode being smaller than a blood vessel and the electrode being deployed from the catheter into a blood vessel proximate to the neural tissue, thereby being able to measure a signal within the blood vessel, said signal being indicative of the electrical brain activity of the neural tissue;
a wire connected to the electrode and for monitoring the signal on the electrode; and
a computer connected to said wire and for determining neural information based on said signal.

Abstract
A system and method for interfacing a brain with a machine. An exemplary embodiment of the present invention employs a vascular approach in which one or more nano-electrodes are deployed in vasculature having a close geometric relationship with proximal innervation. Each nano-electrode is preferably deployed in a blood vessel so that its sensing end is at or near a nerve passing close to or intersecting the blood vessel. The sensing end of each nano-electrode is adapted so as to be carried along in the blood stream so as to position the sensing end at a desired point within the blood vessel. An array of nano-electrodes of varying lengths can be used to monitor multiple nerves or neurons along a blood vessel.
