Patent ID: 7450997

Claim:
A method of implanting a brain stimulating lead, consisting essentially of: identifying a theoretical target for brain stimulation; creating a point of entry into the brain; inserting a lead and a microelectrode into the brain to a position above the theoretical target; advancing the microelectrode toward the theoretical target to locate a stimulation target; advancing the lead to the stimulation target located by the microelectrode; performing test stimulation with the lead to confirm location of the stimulation target; removing the microelectrode; and securing the lead, wherein inserting the lead and the microelectrode comprises, holding a first cannula in a substantially fixed position external to the body; 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 into the body; inserting the lead and the microelectrode through the second cannula; and pulling the second cannula away from the patient's brain.
