Wireless, implantable electro-encephalography system
First Claim
1. An electro-encephalography system, comprising:
- (a) an internal device for implantation below a scalp and above a skull of a patient, the internal device comprising;
(i) a first electrode disposed on a first side of the internal device for receiving a first signal comprising neurological signals originating from the patient'"'"'s brain and artifacts originating from sources other than the patient'"'"'s brain, the first signal comprising a first ratio of the neurological signals to the artifacts;
(ii) a second electrode disposed on a second side of the internal device for receiving a second signal comprising the artifacts; and
(iii) a therapy device for providing therapy to the patient; and
(b) an external device in wireless communication with the internal device, the external device to be worn or carried outside the patient'"'"'s body, the external device comprising a processing unit for;
(i) providing power to the internal device;
(ii) receiving data from the first and second electrodes, the data comprising the first and second signals;
(iii) processing the received data by subtracting at least a portion of the second signal received from the second electrode disposed on the second side of the internal device from the first signal received from the first electrode disposed on the first side of the internal device;
(iv) determining a neurological state of the patient based on the processed signal; and
(v) transmitting instructions to the therapy device for providing therapy to the patient according to the neurological state.

Abstract
An electro-encephalography system includes an internal device for implantation below a scalp and above a skull of a patient, and an external device to be worn or carried outside the patient'"'"'s body. The internal device includes a first electrode for receiving neurological signals originating from the patient'"'"'s brain and a second electrode for receiving artifacts originating from sources other than the patient'"'"'s brain. The external device includes a processing unit for receiving data from the internal device, mitigating the effects of the artifacts, and determining a neurological state of the patient. A therapy device is included to provide a therapy to the patient based on the patient'"'"'s neurological state.
