DEVICE: Rhythmlink® (00816312026535)

A noninvasive electrical conductor designed to be attached to the scalp surface of a patient to transmit changes in the electrical potential of various areas of the brain for recording/monitoring by a connected parent device [i.e., an electroencephalograph (EEG), sleep, or evoked potential recording device]. It typically consists of a small cup/disk with a conductive surface (e.g., tin, gold, conductive plastic) and a length of insulated connecting wire; it may be available as a set of multiple electrodes (e.g., EEG electrodes) however it is not a preconfigured EEG cap. This is a single-patient device that may be reapplied to the patient over a short term (single-use) before being discarded.

An electrical conductor designed to be attached to the skin surface of a patient outside of the hair line (i.e., non-scalp) to conduct electrical signals to/from a parent device for electrophysiological recording/monitoring [e.g., electromyography (EMG), evoked potentials (EP), nerve conduction study (NCS), bioelectrical impedance]; it is not primarily intended for diagnostic electrocardiography (ECG) or electroencephalography (EEG). It typically consists of a small rectangular tab or cup/disk with a conductive surface, which may include a lead wire. This is a single-patient device that may be reapplied to the patient over a short term (single-use) before being discarded.
