Systems and methods of reducing artifact in neurological stimulation systems
First Claim
Patent Images
1. A system to reduce artifact in a signal acquired from a subject, the system comprising:
- a sensing assembly adapted to acquire a signal from a subject indicative of the subject'"'"'s brain activity;
a stimulation assembly adapted to stimulate one or more neurons of the subject; and
a timing controller programmed to control the time at which the sensing assembly acquires the signal to be substantially different than when the stimulation assembly stimulates the subject.

Abstract
The present invention relates to neurological systems and methods of use which acquire physiological signals from a subject and stimulate the subject. The system is adapted to control the timing at which the system acquires the physiological signals from the subject and the timing of the stimulation signal to reduce the amount of stimulation induced artifact that is acquired by the system.

22. A method of reducing artifact in a signal acquired from a subject, the method comprising:
-
acquiring a signal from a subject indicative of the subject'"'"'s brain activity; stimulating the subject; and controlling the time at which the acquiring the signal occurs to be substantially different than the stimulating the subject. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of managing seizures, the method comprising:
-
acquiring an EEG signal from a subject during multiple discrete acquisition times occurring in a regular pattern; stimulating one or more neurons of the subject during multiple discrete stimulation times occurring in a regular pattern; and controlling the times at which the acquiring the EEG signal occurs to be substantially different than the stimulating the one or more neurons of the subject.
