The document describes a mechanical implant (femoral component for hip replacement) and its material properties and testing. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device, an INFINTY® Titanium Anodized Distal Femoral Component, is used in total hip arthroplasty to reduce or relieve pain and improve hip function, which are therapeutic outcomes.
No
This device is a hip implant, specifically a distal femoral component, used for hip arthroplasty to treat various degenerative joint diseases and fractures. It is a therapeutic device designed for surgical implantation, not for diagnosing medical conditions.
No
The device description explicitly details a physical implant (distal femoral component) made of titanium alloy, which is a hardware component, 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.
- Device Description: The provided text describes a surgical implant – a distal femoral component for total hip arthroplasty. This device is physically implanted into the patient's body during surgery.
- Intended Use: The intended use is to replace a damaged hip joint to reduce pain and improve function. This is a therapeutic intervention, not a diagnostic test.
The device is a medical device, but it falls under the category of implantable devices or surgical devices, not IVDs.

Intended Use / Indications for Use
in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:
- Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia;
- Inflammatory degenerative joint disease such as rheumatoid arthritis;
- Correction of function deformity:
- Revision procedures where other treatments or devices have failed; and
- Treatment of nonunion, femoral neck, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques.

Device Description
The INFINTY® Titanium Anodized Distal Femoral Component is a product line addition to the INFINTY® Hip System. This modular system consists of a distal femoral component and a trochanteric module which are assembled by the surgeon at the time of surgery to yield a collared or collarless femoral hip prosthesis. The INFINTY® Hip System is designed for use with cobalt chrome or ceramic femoral heads. The INFINTY® Titanium Anodized Distal Femoral Components are available in standard and microtaper designs. Indications, design features, and functional requirements remain the same. The INFINTY® Titanium Anodized Distal Femoral Components are intended to be used in cemented or uncemented applications. The stems are manufactured from titanium alloy in conformance with ASTM F 136, and are anodized in an additional step to improve resistance to fretting corrosion and improve fatigue characteristics.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.
(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
