The summary does not mention any AI or ML capabilities, image processing, or data sets typically associated with AI/ML development. The device description focuses on materials and geometry.
Yes
The device is a medical implant (Segmental System components, Variable Stiffness Stem extensions) intended to treat bone loss, deformities, and instability, which are conditions that impair normal bodily function. This aligns with the definition of a therapeutic device.
No
The device is indicated for treatment (replacement of bone, correction of deformities) rather than diagnosis.
No
The device description clearly states the device is made from physical materials (Zimaloy™ Cobalt-Chromium-Molybdenum Alloy and Tivanium™ Ti-6Al-4V Alloy) and is intended for surgical implantation, indicating it is a hardware device, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The description clearly states that this device is a "Segmental System" intended for use in the "proximal and mid-shaft portion of the femur" and for "replacement of the mid-shaft portion of the femur". These are implantable devices used within the body, not for testing samples outside the body.
- Intended Use: The intended use describes surgical procedures and conditions related to bone loss, instability, and deformities of the knee and femur, all of which are treated with implanted devices.
Therefore, this device falls under the category of a surgical implant or prosthetic device, not an in vitro diagnostic.

Intended Use / Indications for Use
General Indications for the Segmental System:
- This device is indicated for:
- Moderate to severe knee instability
- Significant bone loss and/or ligament deficiencies caused by neoplasms, trauma, rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, and/or avascular necrosis of the femoral condyle
- Valgus, varus or flexion deformities
- The salvage of previously failed surgical attempts
Indications specific to the Variable Stiffness Stem extensions:
- Variable Stiffness stem extensions require the t use of either a smooth or Trabecular Metal stem collar, which must be cemented to the stem. Following cementing to the stem, the smooth collar must be cemented against the bone, but the remainder of the stem must be used uncemented.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.

Dear Mr. Williman:
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.
