The summary describes a basic electroglottograph and explicitly states "Not Found" for mentions of AI, DNN, or ML, as well as image processing and performance study details typically associated with AI/ML devices.
No.
The device is used for evaluating vocal fold contact information in normal speakers or those with pathologies for research or clinical purposes, not for treating conditions.
Yes
The device is used to evaluate vocal fold pathologies, which is a diagnostic purpose.
No
The device description explicitly states "Electroglottograph," which is a hardware device used to measure vocal fold contact. The summary does not mention any software-only components or functions.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes evaluating vocal fold contact information for research or clinical purposes related to vocal fold pathologies. This involves analyzing physiological signals directly from the patient's body (vocal folds).
- Device Description: The device is an Electroglottograph, which is a non-invasive device that measures electrical impedance changes across the larynx to infer vocal fold contact. This is a physiological measurement, not an in vitro test.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing samples taken from the body (blood, urine, tissue, etc.).
- Using reagents or other substances to perform a test on a sample.
- Providing information about a disease or condition based on the analysis of a sample.
The device appears to be a physiological monitoring or diagnostic device that directly measures a physical characteristic of the patient's body.
N/A
Intended Use / Indications for Use
The device use would be indicated in those cases where vocal fold contact information is considered helpful in evaluating physiologically normal speakers for research purposes or clinically in cases of vocal fold pathologies.

§ 874.1325 Electroglottograph.
(a)
Identification. An electroglottograph is an AC-powered device that employs a pair of electrodes that are placed in contact with the skin on both sides of the larynx and held in place by a collar. It is intended to measure the electrical impedance of the larynx to aid in assessing the degree of closure of the vocal cords, confirm larygeal diagnosis, aid behavioral treatment of voice disorders, and aid research concerning the laryngeal mechanism.(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

Dear Mr. Harbeson:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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.
If your device is classified (see above) into either class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the requlation entitled. "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597, or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
Sincerely yours,
