Abstract
An intra-calvarial implant (ICI) includes a housing including a sealed compartment having a top part, a bottom part and a side wall, and a current directing mechanism extending from the bottom part of the sealed compartment. The ICI also includes one or more electrodes for sensing electrical signals from the brain and/or for electrically stimulating one or more regions of the brain. The ICI includes at least one auxiliary electrode (that may be a reference and/or source/sink electrode) and an electronic circuitry module (ECM), sealingly disposed within the sealed compartment and operatively connected to the one or more electrodes and to the at least one reference electrode. The ECM controls the operation of the ICI and wirelessly communicates with an external telemetry device. The ICI includes a power harvesting device electrically connected to the ECM of the ICI for providing power thereto.
