More Information

Not Found

No
The summary describes a fixed-size, off-the-shelf cranial implant made of PMMA. There are no mentions of AI, ML, image processing, or any data-driven algorithms in the device description, intended use, or performance studies.

Yes.
The device is intended to correct and/or restore bony voids and/or defects of the cranium, which provides a therapeutic benefit by addressing a medical condition.

No
The device is a cranial implant designed to correct and restore bony voids and defects. It is a prosthetic device for treatment, not for diagnosing conditions.

No

The device description explicitly states that the device is a "fixed size prosthetic cranioplasty plate" manufactured from "polymethyl methacrylate materials," indicating it is a physical implant, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body (in vitro).
  • Device Description: The Longeviti ClearFit™ OTS Cranial Implants are described as "fixed size prosthetic cranioplasty plates intended to correct and/or restore bony voids and/or defects of the cranium." This is a device that is implanted into the body to physically repair a defect.
  • Intended Use: The intended use is to "correct and/or restore bony voids and/or defects of the cranium." This is a surgical intervention, not a diagnostic test performed on a sample.

The information provided clearly indicates this is a surgically implanted device used for structural repair, not a diagnostic test performed on a biological sample.

Dear Heather Hourihan:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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 Part

1

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
