Methods and systems for intracranial neurostimulation and/or sensing
First Claim
1. A device for delivering electrical signals to at least a portion of a brain of a patient, comprising:
- an electrode, the entire electrode being made of electrically conductive material and thus the electrode being electrically conductive, the electrode being generally a “
T”
shaped electrode;
an electrically insulating material at least substantially clad about the electrode;
the electrode having a head and a shaft, the head to be positioned adjacent to an outer portion of the skull of the patient, the head for stabilizing the shaft relative to the skull;
the head of the electrode having a top portion and a bottom portion, with the bottom portion being contoured to substantially match the contour of the portion of the skull of the patient proximate to where the electrode is inserted into a hole of the skull of the patient;
the shaft extending from the head with a first end distal the head, at least a first electrical contact positioned at the first end of the shaft, the shaft for insertion into the hole of the skull of the patient such that the electrical contact at the first end of the shaft is positioned adjacent to and in electrical contact with the surface of the brain of the patient, wherein the electrode can transmit electrical signals received from an external controller electrically connected to the head of the electrode to the brain of the patient.

Abstract
Methods and systems for intracranial neurostimulation and/or sensing are disclosed. An intracranial signal transmission system in accordance with an embodiment of the invention includes a generally electrically insulating body having a head portion configured to be positioned at least proximate to an outer surface of a patient'"'"'s skull, and a shaft portion configured to extend into an aperture in the patient'"'"'s skull. The system can further include at least one electrical contact portion integrated with the support body. The at least one electrical contact portion can be positioned to transfer electrical signals to, from, or both to and from the patient'"'"'s brain via an aperture in the patient'"'"'s skull.
