DEVICE: Guideline 4000™ 5.0 (00873263006740)

An electrically-powered device designed for noninvasive recording of the electrical activity of the brain for display in the form of a graph [electroencephalogram (EEG)], typically to study a variety of neurological conditions, evaluate psychiatric disorders, and/or assist in localizing tumours or lesions on or near the surface of the brain. It is designed to acquire electrical signals from electrodes typically attached to the scalp and ear lobes. The results may be displayed via print-out or electronically; data interpretation and/or telemetry features may also be included.

An assembly of mains electricity (AC-powered) devices designed to monitor and provide electrical stimuli to spinal nerves or other neural pathways (may include the brain) during intraoperative surgery or intensive care, typically to reduce the incidence of accidental injury during instrumented spine surgery, or to diagnose acute dysfunction in corticospinal conduction (e.g., due to traction, shearing, laceration, compression, or vascular insufficiency). It typically displays electroencephalogram (EEG), electromyogram (EMG), and/or evoked responses. It typically includes an electric current pulse generator, electrodes and/or probes, and audible and/or visual indicators.
