The summary describes a physical prosthesis made of p.t.f.e. and makes no mention of software, algorithms, or AI/ML terms.
Yes
The device is intended to improve or restore hearing by replacing absent or defective bodily structures, which classifies it as a therapeutic device.
No
Explanation: The device is a prosthesis intended to restore hearing by replacing absent or defective ossicles. This is a therapeutic function, not a diagnostic one.
No
The device description explicitly states it is manufactured from p.t.f.e., indicating it is a physical implant, 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 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.
- Device Description and Intended Use: The Mills Columella is a prosthesis intended to be surgically implanted in the middle ear to replace absent or defective ossicles (incus and stapes). It is a physical implant used for structural reconstruction, not for testing biological samples.
- Lack of IVD Characteristics: The description does not mention any testing of samples, analysis of biological markers, or any other activity typically associated with IVDs.
Therefore, the Mills Columella is a surgical implant, not an In Vitro Diagnostic device.

Dear Ms. Blackmore:
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 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 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.
