Methods and Systems for Measuring a Subject's Susceptibility to a Seizure
First Claim
1. A system for monitoring a subject'"'"'s susceptibility for having a seizure:
- a sensor adapted to detect a brain activity signal;
an implanted communication assembly in communication with the sensor, the implanted communication assembly configured to sample the brain activity signal with the sensor;
an external assembly that is positioned outside the subject'"'"'s body that is configured to receive a data signal from the implanted communication assembly and indicate a subject'"'"'s susceptibility to a seizure; and
an alert that is configured to indicate that there is a communication error between the implanted assembly and the external assembly.

Abstract
Systems and methods for monitoring physiological signals from a subject to determine the subject'"'"'s susceptibility for having a seizure. Also includes are systems and methods for activating an alert when there is a communication error between an implanted device and the external assembly. Additionally included are systems and method for long-term substantially continuous physiological signal data collection. At least a portion of the systems of the present invention may be implanted within the subject. In some embodiments, brain activity signals are sampled from the subject with implanted electrodes and are communicated to an external assembly where the brain activity signals are analyzed to determine the subject'"'"'s susceptibility for having a seizure.

19. A method of activating an alert when there is a communication error between an implantable device and a device external to a subject, the method comprising:
-
sampling a brain activity signal from the subject; transmitting a data signal indicative of the sampled brain activity signal from an implanted assembly to an external assembly outside of the ; and activating an alert when there is a communication error between the implanted assembly and the external assembly. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A seizure advisory device, comprising:
-
a user interface that comprises an indicator that indicates if the subject is at a low susceptibility to a seizure or a high susceptibility to a seizure; and an alert that is configured to provide an indication to the subject if the seizure advisory device is out of communication range with an implantable telemetry unit and is unable to accurately communicate the subject'"'"'s susceptibility to the seizure. - View Dependent Claims (37)

-
38. A method of informing a subject when a seizure advisory device is out of communication range with an implantable device, the method comprising:
-
receiving a transcutaneously transmitted data signal indicative of the sampled brain activity signal from an implanted device; and activating an alert when an expected data signal transmitted from the implanted device is not received by the seizure advisory device. - View Dependent Claims (39, 40, 41)

42. A system for monitoring a subject'"'"'s susceptibility for having a seizure:
-
a sensor adapted to detect a brain activity signal; an implanted communication assembly in communication with the sensor, the implanted communication assembly configured to sample the brain activity signal with the sensor; an external assembly that is positioned outside the subject'"'"'s body that is configured to receive a data signal from the implanted communication assembly and indicate a subject'"'"'s likelihood of transitioning into a seizure condition; wherein the external assembly is further configured to alert the subject when there is a communication error between the implanted assembly and the external assembly; and an input on the external assembly that allows the subject to deactivate an alert function when the subject has a low likelihood of transitioning into the seizure condition. - View Dependent Claims (43, 44, 45, 46)
