Box 13009 88112 Eilat ISRAEL Re: K970180 Trade/Device Name: VSA 3000 Vibratory Sensory Analyzer Regulation Number: 21 CFR 882.1200 Regulation Name: Two-point discriminator Regulatory Class: Class I Product Code: LLN Dated: January 8, 1997 Received: January 17, 1997 Dear Mr. Rosen: This letter corrects our substantially equivalent letter of April 25, 1997. 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 Parts 801 and 809); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements {1} Page 2 – Mr. Emanuel A. Rosen 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.

Rosen - official correspondent for MEDOC LTD., Ramat Yishai, Israel P.O. Box 1309 Eilat, ISRAEL Tel: International + 972 7 637-9645 Fax: International + 972 7 633-1069 Other commercially available devices: Bio-thesiometer - Bio-Medical Instruments Co. - available for over 50 years. Vibraton II, Vibration Sensitivity Tester - Sensortek - K863607 approved 1986 Case IV - WR Medical Electronics Co. - K910624 approved in 1993 The VSA 3000 - Vibratory Sensory Analyzer is a computerized device for the quantitative assessment of large nerve fiber dysfunction, designed for both clinical and advanced research applications. It measures the sensory threshold for vibration. These thresholds deviate from the normal range in: - Metabolic neuropathies - Neurological disease associated with the workplace - Neuropathies due to drug toxicity - Pain assessment - Lesions of the central nervous system Vibratory testing is also a useful tool in tracking the progression of disease or response to treatment. Page 1 of 2 0004 {4} 510(K) SUMMARY [as per 21 CFR 807.92] Page 2 of 2 8 January, 1997 The VSA 3000 can also be used in the early detection and clinical evaluation of peripheral nerve dysfunction as well as being a useful tool in tracking the progression of disease or response to treatment. The various devices used in Vibration Threshold Measurement all operate by means of applying varying amounts of vibration to the skin by the use a controller which allows the operator to vary the amount of vibration delivered. The patient then indicates awareness of the vibrations either verbally or, in the VSA 3000, by pressing a patient response button. There are various protocols available for testing sensitivity such as Forced choice, Limits, Levels and Staircase, from which the tester may choose. The VSA 3000 and Case IV both have data processing features while the Bio-Thesiometer and the Vibraton II do not. All the devices are similar in their energy source and design as well as meeting the various standards for clinical safety. The VSA 3000 is designed and manufactured to meet various domestic and international standards such as: UL 544; UL 2601-1/1994; EN 60601-1-2. 0005 --- **Source:** [https://fda.innolitics.com/submissions/NE/subpart-b%E2%80%94neurological-diagnostic-devices/LLN/K970180](https://fda.innolitics.com/submissions/NE/subpart-b%E2%80%94neurological-diagnostic-devices/LLN/K970180) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
