No
The summary describes a mechanical implant and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is indicated for intractable pain and to replace the functionality of the joint due to deformity, which are therapeutic goals.
No
The document describes a medical implant (wrist joint replacement system) intended to replace a damaged joint, not a device used for diagnosis.
No
The device description explicitly lists physical components (radial implant, carpal plate implant, carpal polymer component, bone screws) made of materials with a clinical history, indicating it is a hardware medical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for replacing the functionality of the wrist joint due to various conditions causing intractable pain. This is a surgical implant used in vivo (within the body).
- Device Description: The description details the components of a surgical implant system (radial implant, carpal plate implant, carpal polymer component, bone screws) and its intended use with cement. These are all components of a medical device used for surgical intervention.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are used outside the body to analyze samples. This device is a surgical implant used inside the body.

Device Description
The KMI Universal Total Wrist (UTW) System (both predicate and extra small) consists of the following components: the radial implant, the carpal plate implant, the carpal polymer component, and two bone screws. The system will now be offered in 4 (four) sizes: 'extra small', 'small', 'medium' and 'large'), each with 3 (three) matching polymer component sizes, which are available in yarvina thicknesses (height); standard, +1 and + 2, It is constructed of materials that have a long clinical history of proven acceptance and performance. This system is intended for use with cement and will be promoted as such in the UTW Surgical Protocol. Engineering drawings of the new size (extra small) and predicate UTW (small) components are shown in Exhibit III.

§ 888.3800 Wrist joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A wrist joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a wrist joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have either a one-part radial component made of alloys, such as cobalt-chromium-molybdenum, with an ultra-high molecular weight polyethylene bearing surface, or a two-part radial component made of alloys and an ultra-high molecular weight polyethylene ball that is mounted on the radial component with a trunnion bearing. The metallic portion of the two-part radial component is inserted into the radius. These devices have a metacarpal component(s) made of alloys, such as cobalt-chromium-molybdenum. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

PREDICATE DEVICE INFORMATION
The principal predicate device for this modification is the Kinetikos Medical Universal Total Wrist System -sizes Small, Medium and Large- originally cleared by FDA on June 6, 1996 under K961051, and modified system version cleared May 03, 2002 under K020554.
PACKAGING/LABELING/PRODUCT INFORMATION
Packaging and labeling of the device will be the same as that of the predicate Universal Total Wrist. The device will continue to be indicated for cemented use only. Samples of a package label, product brochure and the surgical technique manual with draft changes in product illustrations, are shown in Exhibit II.
INTENDED USE
The Extra Small KMI Universal Total Wrist implant is indicated for intractable pain resulting from traumatic arthritis, osteoarthritis, theumatoid arthritis, trauma-induced osteoarthritis of the radial/carpal joint. To replace functionality of the joint due to deformity or elements stated above. The Universal Total Wrist is intended for cemented use.

SYSTEM DESCRIPTION
The KMI Universal Total Wrist (UTW) System (both predicate and extra small) consists of the following components: the radial implant, the carpal plate implant, the carpal polymer component, and two bone screws. The system will now be offered in 4 (four) sizes: 'extra small', 'small', 'medium' and 'large'), each with 3 (three) matching polymer component sizes, which are available in yarvina thicknesses (height); standard, +1 and + 2, It is constructed of materials that have a long clinical history of proven acceptance and performance. This system is intended for use with cement and will be promoted as such in the UTW Surgical Protocol. Engineering drawings of the new size (extra small) and predicate UTW (small) components are shown in Exhibit III.
EQIVALENCE TO MARKETED PRODUCT
The size extra small has the following similarities to the predicate UTW implants which previously received 510(k) concurrence:
- -identical design
- -identical materials
- -identical operating principle
- -is packaged and sterilized using identical materials and processes
Its one distinct difference is that the size extra small is 9% smaller than the size small. In summary, the extra small Universal Total Wrist System described in this submission is, in our opinion, substantially equivalent to the predicate device.

Dear Mr. Spampinato:
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.
