The summary describes a passive, mechanical implant and contains no mention of AI, ML, image processing, or data analysis that would suggest the use of such technologies.
Yes
The device is intended to replace parts of the thumb to address conditions like rheumatoid arthritis, traumatic arthritis, and osteoarthritis, which are therapeutic interventions.
No
The device is described as a prosthesis intended to replace a part of the thumb, not to diagnose a condition.
No
The device description clearly states it is a physical prosthesis fabricated from pyrocarbon and graphite, intended to be implanted in the basal thumb joint. This is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a prosthesis intended to replace a part of the thumb joint. This is a surgical implant used in vivo (within the body) for treatment.
- Device Description: The description details a physical implant made of pyrocarbon and graphite, designed to be surgically placed.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is a surgical implant used in vivo.

Device Description
The Ascension PyroHemiSphere (PHS) is single-use, uncemented, onc-component prosthesis for the basal thumb joint. It is fabricated from a thick pyrocarbon layer encasing a graphite core that is impregnated with one-atomic percent tungsten so it is radiopaque. The device is available in five sizes and is provided sterile in packaging containing a single component.

DEVICE DESCRIPTION:
The Ascension PyroHemiSphere (PHS) is single-use, uncemented, onc-component prosthesis for the basal thumb joint. It is fabricated from a thick pyrocarbon layer encasing a graphite core that is impregnated with one-atomic percent tungsten so it is radiopaque. The device is available in five sizes and is provided sterile in packaging containing a single component.
INTENDED USE:
The Ascension® PyroHemiSphere™ is intended to replace the proximal end of the first mctacarpal in cases of rheumatoid arthritis, traumatic arthritis, osteoarthritis or post fracture deformation or bone loss which present as either a painful, unstable thumb, or a thumb with limited range of motion.
BASIS OF SUBSTANTIAL EQUIVALENCE:
A comparison of the design features as well as performance tests demonstrate that the Ascension PyroHemiSphere is substantially equivalent to the predicate device.

Dear Mr. Strzepa:
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 (Special 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. This letter will allow you to begin marketing your device as described in your Section 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.
