More Information

Not Found

No
The summary describes a mechanical cutting tool and does not mention any AI or ML components or functions.

No.
The device is described as a cutting accessory intended for creating access holes through the cranium, which is a surgical tool, not a therapeutic device designed for treating a disease or condition.

No

Explanation: The device is described as a "cutting accessory" or "mechanically powered tool" for creating an access hole through the cranium. Its function is to perform a physical action (cutting), not to identify, detect, or monitor a medical condition or disease.

No

The device description clearly states it is a "mechanically powered tool" and a "cutting accessory," indicating it is a physical hardware device, not software.

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 taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Stryker Zyphr Disposable Cranial Perforator is a surgical tool used to create a physical opening in the skull. It is a cutting accessory used directly on the patient's body, not on a sample taken from the body.
  • Intended Use: The intended use clearly states it is for "cutting an access hole through the cranium." This is a surgical procedure, not a diagnostic test performed on a sample.

Therefore, the device falls under the category of a surgical instrument or accessory, not an in vitro diagnostic device.

Dear Ms. O'Connor:

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.

If your device is classified (see above) into either class II (Spccial Controls) or class III (PMA), 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 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); 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.
