1. A method of introducing a brain stimulating lead into a patient'"'"'s brain composing:

  • holding a first cannula in a substantially fixed position completely external to the brain;

    slidably supporting a second cannula with the first cannula;

    positioning the second cannula with a proximal end extending beyond the proximal end of the first cannula and a distal end extending beyond the distal end of the first cannula and so that the second cannula extends at least partially into the patient'"'"'s brain;

    inserting the brain stimulating lead through the second cannula;

    using the second cannula as a macroelectrode, wherein the macroelectrode is attached to the second cannula;

    using a stereotactic frame to hold the first cannula in a substantially fixed position; and

    pulling the second cannula away from the patient'"'"'s brain, wherein the second cannula includes at least two splittable sections having a perforated interface.
