The device "supports clinician guided, intermittent electrical stimulation of the brain cortex to support diagnostic and surgical procedures" and is "intended for use in functional brain mapping procedures... providing stimulation via electrode pairs or a hand held bipolar probe." Functional brain mapping is a diagnostic procedure to identify critical brain regions.
No
The device description explicitly details hardware components (Stimulus Switching Unit, Cortical Stimulator Control Unit, external power supply) and mentions hardware verification and validation in the performance studies summary.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
- This device is used for in vivo (within the body) electrical stimulation of the brain cortex. Its purpose is to directly interact with the patient's brain during a surgical or diagnostic procedure.
The intended use and device description clearly indicate that the Cortical Stimulator is a therapeutic and diagnostic tool used on the patient, not for analyzing samples from the patient.

Intended Use / Indications for Use
The Cortical Stimulator is intended for use in functional brain mapping procedures during treatment of patients with seizure disorder, providing stimulation via electrode pairs or a hand held bipolar probe.

Device Description
The Nicolet Cortical Stimulator supports clinician guided, intermittent electrical stimulation of the brain cortex to support diagnostic and surgical procedures. The cortical stimulation energy is applied through commercially available cortical electrodes (strip and grid electrodes) of a minimum 2.3 mm diametor and a Cardinal Health, NeuroCare stimulation probe. All stimulation is temporary and intermittent, applied in support of functional brain mapping procedures during treatment of patients with seizure disorder.
The Nicolet Cortical Stimulator is a constant current stimulator. The stimulation current and frequency of stimulation is selected by the user. The Nicolet Cortical Stimulator (Cortical Stimulator) consists of two components:
-
- Stimulus Switching Unit and
-
- Cortical Stimulator Control Unit.
The Cortical Stimulator Control Unit (CSCU) is powered by an external power supply. The CSCU provides the current stimulation source. The Stimulus Switching Unit (SSU) directs the stimulation to selected electrodes.
The Cortical Stimulation Control Unit can be used in a stand-alone mode with stimulus provided through the Cardinal Health, NeuroCare stimulation probe. Alternatively the Cortical Stimulation Control Unit can be connected to the Stimulation Switching Unit. When the Stimulus Switching Unit is attached, the Stimulus Switching Unit interfaces between the Nicolet C64 Electroencephalography (EEG) amplifier and the amplifier's associated headbox. The headbox provides the interface between the amplificr and the brain contacting electrodes.

1.0 Description of Device
The Nicolet Cortical Stimulator supports clinician guided, intermittent electrical stimulation of the brain cortex to support diagnostic and surgical procedures. The cortical stimulation energy is applied through commercially available cortical electrodes (strip and grid electrodes) of a minimum 2.3 mm diametor and a Cardinal Health, NeuroCare stimulation probe. All stimulation is temporary and intermittent, applied in support of functional brain mapping procedures during treatment of patients with seizure disorder.
The Nicolet Cortical Stimulator is a constant current stimulator. The stimulation current and frequency of stimulation is selected by the user. The Nicolet Cortical Stimulator (Cortical Stimulator) consists of two components:
-
- Stimulus Switching Unit and
-
- Cortical Stimulator Control Unit.

The Cortical Stimulator Control Unit (CSCU) is powered by an external power supply. The CSCU provides the current stimulation source. The Stimulus Switching Unit (SSU) directs the stimulation to selected electrodes.
The Cortical Stimulation Control Unit can be used in a stand-alone mode with stimulus provided through the Cardinal Health, NeuroCare stimulation probe. Alternatively the Cortical Stimulation Control Unit can be connected to the Stimulation Switching Unit. When the Stimulus Switching Unit is attached, the Stimulus Switching Unit interfaces between the Nicolet C64 Electroencephalography (EEG) amplifier and the amplifier's associated headbox. The headbox provides the interface between the amplificr and the brain contacting electrodes.
1.1 Clinical Application
Prior to and during a surgical procedure to remove epileptic foci or a tumor of the brain, a cortical mapping procedure may be applied. Cortical stimulation may be applied to determine epileptic scizure foci that need to be surgically removed, tissue excised, as the foci are not managed with medications. The cortical stimulator is used with intra cranial cortical electrodes in the form of strips and/or grids temporarily placed on the surface of the patient's cerebral cortex. Having established a "focus" for the patient's epilepsy, the physician performs a number of procedures to establish if surgery is a viable option. Cortical mapping is one of those procedures. Cortical stimulation in support of cortical mapping may be applied during the monitoring period, in the patient epileptic monitoring area.
During cortical mapping electrical stimulation of the patient's cortex is performed through pairs of electrodes temporarily placed on the surface of the brain or by a hand held bipolar stimulator probe. The electroencephalograph (EEG) is recorded during the procedure and the patient is observed in person and through video so as to note and document clinical signs, bchavioral changes and other possible effects, such as speech changes. Thus, the surgeon is able to identify eloquent brain areas and can avoid these if resection of brain tissue is performed.
