DEVICE: microTargeting™ Electrode and Insertion Tube Kit (10873263008918)

A sterile, nonimplantable, rigid tube intended to be surgically inserted through the skull to access the brain (e.g., cerebral ventricles) for cerebrospinal fluid (CSF) drainage, infusion of materials, and/or for use as a port through which instruments, leads and/or probes can be passed to perform a variety of diagnostic, treatment, or surgical procedures. It is usually made of metal (e.g., stainless steel) and may include a stylet/trocar blade. This is a single-use device.

An electrical conductor intended to be temporarily placed (< 30 days) beneath the surface of the brain to stimulate the brain or to record the brain's electrical activity (with more precise localization than a scalp electrode). It is typically a fine, flexible plastic device attached to wires that carry currents from deep and superficial brain structures. The wires are connected to recording, monitoring, or stimulation/response devices [e.g., electroencephalograph (EEG), evoked-potential recorder, stimulator]. The implant is particularly helpful in determining site of origin in temporal and frontal lobe epilepsy. This is a single-use device.
