Intended Use
Kilowin is an electroneurodiagnostic device designed to measure and display the electrical signals generated by peripheral nerve, muscle and central nervous system. It will acquire the data necessary for electroencephalography (EEG), electronystagmography (ENG), electrocardiography (ECG), electromyography (EMG), nerve conduction velocity (NCV, F wave, and H reflex), evoked potentials (EP, brainstem, visual, somatosensory), repetitive nerve stimulation and sleep assessment. The Kilowin instrument is designed for use during the duration of the procedure only. Use of the proposed device is to be administered under the direction of a trained physician, surgeon, neurologist, or electrophysiologist in an operating room or clinic. The Kilowin device(s) are intended for use during electroencephalography (EEG), electronystagmography (ENG), electromyography (EMG), nerve conduction velocity (NCV, F wave, and H reflex), evoked potentials (brainstem, visual, somatosensory), repetitive nerve stimulation testing and sleep assessment.
Device Story
Kilowin is an electroneurodiagnostic system for measuring/displaying electrical signals from peripheral nerves, muscles, and the central nervous system. Inputs include physiological signals acquired during EEG, ENG, ECG, EMG, NCV, evoked potentials, and sleep studies. Device operates in clinics or ORs under direction of physicians, surgeons, neurologists, or electrophysiologists. System acquires, processes, and displays data for diagnostic assessment. Output allows clinicians to evaluate neurological and physiological function, aiding in diagnosis of nerve/muscle/CNS conditions. Intended for use only during the procedure duration.
Clinical Evidence
No clinical data provided; bench testing only.
Technological Characteristics
Electroneurodiagnostic system for signal acquisition and display. Supports multiple modalities: EEG, ENG, ECG, EMG, NCV, evoked potentials, and sleep assessment. Operates as a diagnostic instrument for real-time signal monitoring. Technical specifications and materials not detailed in provided documentation.
Indications for Use
Indicated for patients requiring diagnostic electrophysiological testing including EEG, ENG, ECG, EMG, NCV, F wave, H reflex, evoked potentials (brainstem, visual, somatosensory), repetitive nerve stimulation, and sleep assessment. Administered by trained clinicians in clinical or OR settings.
Regulatory Classification
Identification
An evoked response photic stimulator is a device used to generate and display a shifting pattern or to apply a brief light stimulus to a patient's eye for use in evoked response measurements or for electroencephalogram (EEG) activation.

Dear Mr. Cadwell:
This letter corrects our substantially equivalent letter of June 11, 1998.
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA’s issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act’s requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please go to http://www.fda.gov/AboutFDA/CentersOffices/CDRH/CDRHOffices/ucm115809.htm for the Center for Devices and Radiological Health’s (CDRH’s) Office of Compliance. Also, please note the regulation entitled, “Misbranding by reference to premarket notification” (21CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH’s Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
