No
The device description and intended use are purely mechanical, describing bone screws for fixation. There is no mention of any software, algorithms, or data processing that would suggest AI/ML.
Yes
The device is described as "Bone Screws" intended for "additional bone fixation of the tibial components of the Evolis Total Knee System," which is a "knee replacement system." Its indication for use includes painful and/or disabled joints due to various types of arthritis, avascular necrosis, post-traumatic loss of joint configuration, and primary implantation failure. These are all conditions that require treatment to restore function or alleviate symptoms, making the device therapeutic.
No
The device is described as "bone screws" intended for "additional bone fixation" in a total knee arthroplasty, indicating a therapeutic or supportive function rather than a diagnostic one.
No
The device description clearly states the device is a physical bone screw made of titanium alloy, which is a hardware component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The provided information clearly describes the Medacta Bone Screws as a device intended for surgical implantation to provide additional bone fixation in a total knee replacement system. It is a physical implant used directly within the body.
- Lack of Specimen Analysis: There is no mention of the device being used to analyze any biological specimens. Its function is purely mechanical support within the knee joint.
Therefore, based on the provided information, the Medacta Bone Screws are a surgical implant, not an In Vitro Diagnostic device.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
