Intended Use

The CareFusion Nicolet EDX is intended for the acquisition, display, analysis, storage, reporting, and management of electrophysiological information from the human nervous and muscular systems including Nerve Conduction (NCS), Electromyography (EMG), Evoked Potentials (EP), Autonomic Responses and Intra-Operative Monitoring including Electroencephalography (EEG).

Evoked Potential (EP) includes Visual Evoked Potentials (VEP), Auditory Evoked Potentials (AEP), Somatosensory Evoked Potentials (SEP), Electroretinography (ERG), Electrooculography (EOG), P300, Motor Evoked Potentials (MEP) and Contingent Negative Variation (CNV). The Nicolet EDX with Synergy Software may be used to determine autonomic responses to physiologic stimuli by measuring the change in electrical resistance between two electrodes (Galvanic Skin Response and Sympathetic Skin Response). Autonomic testing also includes assessment of RR Interval variability. The Nicolet EDX with Synergy Software is used to detect the physiologic function of the nervous system, for the location of neural structures during surgery, and to support the diagnosis of neuromuscular disease or condition.

The listed modalities do include overlap in functionality. In general, Nerve Conduction Studies measure the electrical responses of the nerve; Electromyography measures the electrical activity of the muscle and Evoked Potentials measure electrical activity from the Central Nervous System.

The Nicolet EDX with Synergy Software is intended to be used by a qualified healthcare provider.

Device Description

The CareFusion Nicolet EDX system with Synergy Software (Synergy EDX) is designed for the acquisition, display, analysis, reporting, and management of electrophysiological information from the human nervous and muscular systems. The system is designed to perform nerve conduction studies (NCS), needle electromyography (EMG) testing, evoked potential (EP) testing, and intra-operative monitoring (IOM). Synergy EDX provides a variety of tests spanning the various modalities.

The Synergy EDX consists of the following major components:

  • Nicolet EDX console base unit;
  • Synergy control panel:
  • Nicolet amplifier (there are two types available: 2 channel (AT2) with two non-switched amplifier channels and an 8 channel (AT2 + 6) amplifier with two non-switched and six switched amplifier channels;
  • Desktop or laptop computer with a keyboard and mouse;
  • Display monitor; and
  • Synergy Software

The Synergy EDX optional accessories/components consists of the following:

  • Nicolet HB6 or HB7 Head Box
  • Stimulator probes (RS 10 probe, WR 50 Probe, S403 probe)
  • SP1/SP2 electrical stimulator switching units
  • Footswitches (single and triple)
  • LED goggles
  • Patient response button
  • Photic strobe
  • Headphones or other auditory transducers
  • Cart
  • Isolation transformer
  • Printer
AI/ML Overview

This document is a 510(k) Summary for the CareFusion Nicolet EDX with Synergy Software. It primarily serves to demonstrate substantial equivalence to previously cleared predicate devices, rather than presenting a performance study with detailed acceptance criteria and results from a clinical trial or a structured validation study as one might expect for a novel AI/ML device.

Here's an analysis based on the provided text, addressing your points:

The Device: The CareFusion Nicolet EDX with Synergy Software is a diagnostic electromyograph system designed for acquiring, displaying, analyzing, reporting, and managing electrophysiological information from human nervous and muscular systems. It performs nerve conduction studies (NCS), needle electromyography (EMG), evoked potential (EP) testing, and intra-operative monitoring (IOM).

Overview of Acceptance Criteria and Performance (Based on Substantial Equivalence):

This submission is a 510(k) for substantial equivalence, not a new de novo device with specific clinical performance acceptance criteria against a ground truth. The acceptance criteria essentially revolve around demonstrating that the new device has the same technological characteristics, indications for use, and safety/effectiveness as its predicate devices, or that any differences do not raise new questions of safety or effectiveness.

The document primarily shows that the CareFusion Nicolet EDX with Synergy Software is "Identical" or "Similar" to its predicate device, the CareFusion Nicolet EDX with Viking software (K112052), with one minor addition (CNV test to EP modality) and one minor difference in auditory tone frequency that doesn't change indications for use or safety/effectiveness.

1. Table of Acceptance Criteria and Reported Device Performance:

Since this is a substantial equivalence submission relying on comparison to a predicate, the "acceptance criteria" are implied by the similarity to the predicate, and "performance" is demonstrated by showing these similarities through technical specifications, rather than new quantitative performance metrics.
