Not Found

No
The summary describes a mechanical stereotactic system with localizers and image holders, with no mention of AI, ML, or advanced image processing beyond basic localization.

No
The device is a localization system used for planning and performing stereotactic cranial procedures, which is a diagnostic and surgical planning tool, not a therapeutic device that directly treats a condition.

No
The device provides a coordinate system for planning and performing procedures, which is a therapeutic aid, not a diagnostic function.

No

The device description explicitly lists hardware components (headring, CT localizer, X-ray localizer, film holder) as part of the system.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples such as blood, urine, or tissue to detect diseases, conditions, or infections. They are used outside of the body.
  • Device Function: The SNT Stereotactic Localization System is used to provide a coordinate system for planning and performing stereotactic cranial procedures. This involves working directly with the patient's head and using imaging modalities like CT and X-ray.
  • Lack of Biological Sample Analysis: There is no mention of the device analyzing biological samples. Its function is related to spatial localization and guidance during a medical procedure.

Therefore, the device's intended use and description clearly place it outside the scope of In Vitro Diagnostics.

Re: K971675 Trade Name: SNT Stereotactic Localization System Regulatory Class: II Product Code: 84HAW Dated: May 5, 1997 Received: May 7, 1997

Dear Mr. White:

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 to 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 II (Special Controls) or 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 requirement, 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 Pood and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory 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.

Page 2 - Mr. Roger N. White

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) 594-4648. 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).
