Intended Use
System for recording electroencephalogram of brain electrical activity to Host Digital EEG Machine.
Device Description
The NeuroLink NeuroMonitoring System (predicate device) consists of a set of components that work together to acquire and present EEG signal to any existing EEG recording and analysis equipment. The components include Biosensor electrodes, e-Net headpiece, Patient Module, battery module, fiber optic cable, and DSP Interface Card. Changes in the Patient Module and power supply are described in this submission. An electrode headbox has been added to the Patient Module and an AC power supply is available as an alternate to the battery module. The Patient Module is a small battery powered or AC powered amplifier. The EEG signals are transmitted from the head via conventional electrodes that are input into the attached headbox or e-Net that has a mating connector on the patient module. Power is enabled when the Patient Module is plugged into the DSP Card via the fiber optic cable, the host digital EEG computer is in the powered state and the Patient Module is enabled by pressing the control button located on the Patient Module. A five meter fiber optic cable is standard. The fiber optic cable provides patient isolation and flexible patient EEG Record Station placement options. Self test, calibration and impedance tests are remotely activated from the Host Digital EEG Machine through the DSP Interface Card or locally by depressing the appropriate test button on the Patient Module. A visual indication of control button function, system status and out of range impedance can be provided on the LCD display as controlled from the Host Digital EEG Machine.
More Information

Not Found

No
The description focuses on hardware components for signal acquisition and transmission, with no mention of AI/ML algorithms for analysis or interpretation.

No
The device is used for recording brain electrical activity (EEG), which is a diagnostic function, not a therapeutic one. It acquires and presents EEG signals but does not treat or alleviate any condition.

Yes

The device is designed to record electroencephalogram (EEG) of brain electrical activity, which is a diagnostic procedure used to evaluate brain function and detect neurological disorders.

No

The device description explicitly lists multiple hardware components including biosensor electrodes, headpiece, patient module, battery module, fiber optic cable, and DSP Interface Card. It also describes changes to hardware components (Patient Module and power supply).

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "record electroencephalogram of brain electrical activity." This is a measurement of electrical signals from the body, not an analysis of samples taken from the body (like blood, urine, or tissue).
  • Device Description: The description details components for acquiring and transmitting electrical signals from electrodes placed on the head. It doesn't mention any components or processes for analyzing biological samples.
  • Anatomical Site: The anatomical site is the "brain," which is where the electrical activity is being measured, not a source of a biological sample for in vitro analysis.

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic purposes. This device is designed to measure electrical activity in vivo (within the living body).
