Implantable systems and methods for identifying a contra-ictal condition in a subject

A method of monitoring neurological signals from a subject, said method comprising:

• delivering power from an external transmission assembly to an implanted device;
• sampling a neurological signal from the subject with the implanted device;
• transmitting a wireless data signal from within the subject's body to the external transmission assembly, said wireless data signal being encoded with data indicative of the sampled neurological signal;
• and
• analyzing the neurological signal from the subject using a processor to determine if the subject is in a contra-ictal condition, said contra-ictal condition being a neurological state in which the subject is unlikely to transition into an ictal condition within a time period.

A neurological monitoring system comprising:

• an implantable device;
• an external transmission assembly configured to receive a wireless data signal from the implantable device;
• and
• a processing assembly for sampling a signal from a subject,
• wherein the implantable device includes a power assembly for receiving power from the external transmission assembly and a communication assembly for transmitting the wireless data signal from within a subject's body to the external transmission assembly, said wireless data signal being encoded with data indicative of the sampled signal, and
• wherein the processing assembly is configured to process the wireless data signal from the implantable device to determine if the subject is in a contra-ictal condition, said contra-ictal condition being a neurological state in which the subject is unlikely to transition into an ictal condition within a time period.
