1. An intracranial electrode comprising:
- a shaft including a distal contact surface adapted to electrically contact a surface of a patient'"'"'s brain;
a head associated with the shaft, the head being sized to be positioned subcutaneously adjacent the patient'"'"'s skull; and
threads carried by at least one of the head and the shaft, the threads being adapted to fix the electrode with respect to the patient'"'"'s skull;
the electrode having an adjustable length adapted to change a contact force of the distal contact surface against the surface of the brain by adjusting the length of the electrode.

Abstract
Aspects of the invention relate to intracranial electrodes and methods for implanting and using intracranial electrodes. In one particular example, an intracranial electrode includes a shaft having a distal contact surface adapted to electrically contact a surface of a patient'"'"'s brain, a head associated with the shaft, and threads adapted to fix the electrode with respect to the patient'"'"'s skull. This electrode may have an adjustable length adapted to change a contact force of the distal contact surface against the surface of the brain by adjusting the length of the electrode.

19. An intracranial electrode, comprising:
-
an electrically conductive member having a blunt contact surface;
a dielectric member having an interior in which the electrically conductive member is received; and
an anchor carried by the electrically conductive member or the dielectric member and adapted to anchor at least one of the electrically conductive member and the dielectric member with respect to a patient'"'"'s skull adjacent a brain surface such that the contact surface is in electrical contact with the brain surface and the dielectric member electrically insulates the skull from the electrically conductive member. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
