DEVICE: Rhythmlink® (00816312022629)

An electrical conductor intended to be attached to a patient's skin (noninvasive) to provide therapeutic electrical stimuli through the body surface [e.g., transcutaneous electrical nerve stimulation (TENS), electrical muscle stimulation (EMS), cranial electrotherapy stimulation (CES)]. It is typically a flat, flexible, conductive pad with an adhesive (e.g., gel), or a preformed shape/mechanism designed for attachment to a particular body part (e.g., earclip), connected to a conductive wire. This is a single-use device.

A sterile, multi-purpose electrical conductor inserted beneath the dermal layer of a patient's skin to record/monitor electrical activity (biopotentials) for physiological measurements [typically electroencephalography (EEG), electromyography (EMG), and evoked-potential) and often to provide electrical stimulation. It typically consists of thin shaft of stainless steel connected to a lead wire that terminates with a safety connector for attachment to recording/monitoring and stimulation systems. This is a single-use device.

An array of analytical scalp electrodes preconfigured within a head-worn device designed for the rapid placement and appropriate positioning of the scalp electrodes during electroencephalography (EEG). It typically consists of a cap-like device with integrated scalp electrodes, and shielded lead wires that terminate into a connector that mates with a separate cable. The device eliminates the need to glue or paste individual electrodes to the patient’s scalp. This is a single-use device.
