More Information

Not Found

No
The summary describes a system for detecting and quantifying gamma radiation, with no mention of AI, ML, image processing, or any data-driven algorithms typically associated with AI/ML in medical devices. The description focuses on hardware components and basic functionality.

No
The device is used for detection and quantification of radiation, which is a diagnostic function, not a therapeutic one. It measures the amount of radionuclide, rather than treating a condition.

Yes

The device is used for "detection and quantification" of gamma radiation and to "measure the amount of radionuclide absorbed," which directly points to its role in assessing a physiological state or function, characteristic of a diagnostic device.

No

The device description explicitly states it includes hardware components: "a hand-held sensor probes, a counting unit, and a cable interconnecting the two."

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the detection and quantification of gamma radiation from gamma-emitting isotopes in the body or tissues. This involves measuring radiation within the body, not analyzing samples outside the body (which is the core characteristic of an IVD).
  • Device Description: The device description confirms it's a system used for non-imaging procedures involving a hand-held sensor probe and a counting unit. This aligns with in-vivo measurement, not in-vitro analysis of samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) or performing tests on these samples outside the body.

Therefore, this device falls under the category of a medical device used for in-vivo measurement, not an in-vitro diagnostic device.

Dear Mr. Stoppel:

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 Requlations, 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 regulation entitled, "Misbranding by reference to premarket notification"(21 CFR 807.97).
