System components: Biosensor electrodes, e-Net headpiece, patient module, fiber optic cable, DSP interface card, computer hardware, and Administrator software. Input: raw analog EEG signals via electrodes; digitized and archived directly to optical disk without modification or processing. Output: raw EEG waveforms displayed on monitor or printed. Used in clinical settings by trained healthcare professionals for EEG interpretation. Benefits: ensures full fidelity of raw EEG data; provides paper or paperless review options; enables automatic archival. ## Clinical Evidence No clinical data provided. Substantial equivalence is based on the combination of previously cleared components and identical intended use to predicate devices. ## Technological Characteristics System includes biosensor electrodes, e-Net headpiece, patient module, fiber optic cable, DSP interface card, and computer hardware. Operates as an EEG recording system. Software is used for display and printing of raw digitized EEG data. No signal processing or modification of raw data occurs. Connectivity includes optical disk archival. ## Regulatory Identification An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head. ## Predicate Devices - HydroDot NeuroMonitoring System ([K930080](/device/K930080.md)) - UNIQUANT™ System (K905435B) ## Reference Devices - NeuroLink NeuroMonitoring System ([K962157](/device/K962157.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Five Billerica Park 101 Billerica Avenue N. Billerica, MA 01862 Contact: Dawn E. Frazer Director, Regulatory Affairs & Quality Assurance (508) 670-2422 (800) 474-9746 Subject Device: Equinox™ Digital EEG System Predicate Device: K930080, HydroDot NeuroMonitoring System K905435B UNIQUANT™ System This submission describes an EEG recording system that is comprised of a combination of components described in two separate 510(k) submissions. The system components are Biosensor electrodes, e-Net Headpiece, Patient Module, Fiber Optic Cable, DSP Interface Cable, Computer Hardware and Software Application. The first three items were originally discussed in Physiometrix Premarket Submission K930080, HydroDot NeuroMonitoring System. Subsequently several modifications have been submitted to the FDA for review. This file, Physiometrix Premarket Submission K962157, NeuroLink NeuroMonitoring System, is pending substantial equivalence decision. Therefore, all applicable items contained in K962157 have been duplicated in this submission. The last two items, the computer hardware and software application are described in Neuro Concepts K905435B, UNIQUANT™ System. The software application described in this submission is called the Administrator. A business agreement has been arranged between Physiometrix and Neuro Concepts, Inc. whereby the Administrator software application will be incorporated into the Physiometrix System by Neuro Concepts, Inc. Classification: Class II, CFR 21 Part 882.1320, Cutaneous Electrodes Class II, 21 CFR Part 882.1400, Electroencephalograph Class II, 21 CFR Part 882.1835, Physiological Signal Amplifier - page 6 - {1} Physiometrix, Inc. 510(k), Premarket Notification Equinox™ Digital EEG System ## Description: The Equinox™ Digital EEG System incorporates products produced by Physiometrix and Neuro Concepts to provide a superior system for EEG recording that provides cost benefits to the user. The Equinox™ System features several Physiometrix products including the Biosensor electrodes, e-Net headpiece, Patient Module, fiber optic cable and DSP Interface Card and computer hardware. The last component of the system is the Neuro Concepts software described in K905435B UNIQUANT™ System. The Equinox™ is an EEG system that offers a choice of paper or paperless approaches to reading of EEG records and automatic archival of EEG data onto optical disks. The highest priority of the system is to ensure the quality of the EEG data acquisition and storage thus preserving the full fidelity of the raw analog EEG waveform for reproduction onto paper or for display on a computer monitor. EEG data that is acquired on the Equinox™ System is always archived directly onto optical disk with no means available to the system operator to modify or process the raw digitized data. ## Intended Use: The Equinox™ System has the same intended use as the Neuro Concepts UNIQUANT™ System, that is preserving the full fidelity of the original EEG waveform data in the EEG patient population while providing tools for displaying and printing EEG waveforms for review and interpretation by trained health care professionals. ## Technology: The Physiometrix Equinox™ System has the same intended use as the predicate devices described in K905435B, UNIQUANT™ System, which is preserving the full fidelity of the original EEG waveform data in the EEG patient population while providing tools for displaying and printing the waveforms for analysis and interpretation by trained health care professionals. The Equinox™ System is similar to the UNIQUANT™ System in that they use identical computer hardware and software applications. The Equinox™ System differs mainly from the UNIQUANT™ in that the Equinox™ is comprised of all the components necessary to acquire and display waveforms. The UNIQUANT™ system does not include electrodes or electrode placement tools that are a part of the Equinox™ System. These components are described in the Physiometrix K930080. ## Conclusion: The requirements of the Equinox™ System are consistent with the basic functionality of the predicate devices as well as conventional EEG machines that acquire and display EEG records on paper. Since there is no change in intended use from either of the predicate devices, there are no failure modes or latent design flaws in the software that would be expected to result in physical injury to the patient. Thus, the software that controls this device poses no - page 7 - {2} Physiometrix, Inc. 510(k), Premarket Notification Equinox™ Digital EEG System substantial risk or danger to the patient. It therefore meets the criteria for minor concern as outlined in the FDA Draft Reviewer Guidance for Computer Controlled Products. The concern is minor because even if there is an inadvertent misuse of the software, there is no risk or danger to the patient. - page 8 - --- **Source:** [https://fda.innolitics.com/submissions/NE/subpart-b%E2%80%94neurological-diagnostic-devices/GWQ/K962447](https://fda.innolitics.com/submissions/NE/subpart-b%E2%80%94neurological-diagnostic-devices/GWQ/K962447) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
