Closed-loop feedback for steering stimulation energy within tissue
First Claim
1. A neurostimulation system, comprising:
- a plurality of electrical terminals configured for being electrically coupled to a plurality of electrodes;
output stimulation circuitry configured for conveying electrical energy between the electrodes, thereby creating a stimulation region in tissue of a patient when the electrodes are located adjacent the tissue;
monitoring circuitry configured for sensing a cognitive brain signal; and
control circuitry configured for analyzing the sensed cognitive brain signal and for controlling the output stimulation circuitry to displace a locus of the stimulation region relative to the tissue based on the analysis of the sensed cognitive brain signal.

Abstract
Methods, systems, and external programmers provide therapy to a patient having a dysfunction. In one aspect, electrical energy is conveyed between electrodes to create a stimulation region in tissue adjacent the electrodes. Physiological information from the patient is acquired and analyzed, and a locus of the stimulation region is electronically displaced relative to the tissue based on the analysis of the acquired physiological information. In another aspect, electrical energy is delivered to tissue of the patient in accordance with one or more stimulation parameters. A cognitive brain signals is sensed and analyzed, and the stimulation parameter(s) are modified based on the analysis of the cognitive brain signal.
