Intended Use
The Implex Alumina Femoral Head is intended to provide articulation in total hip procedures in cases of: 1. Severely disabled joints as a result of degenerative arthritis or avascular necrosis. 2. Secondary revision of a previously unsuccessful femoral component or total hip replacement. 3. Other hip problems where clinical experience has shown that alternative modes of treatment are less likely to achieve satisfactory results. 4. Fracture dislocation of the hip or irreducible fractures in which adequate fixation cannot be obtained. 5. Non-Union of femoral neck or head fractures. 6. Salvage of a failed primary or secondary total hip or hemi-hip arthroplasty.
Device Description
The Implex Alumina Femoral Head is a ceramic femoral head. The Implex Alumina Femoral Head is offered in a 28 mm OD with +0, +3, and +6 neck offset lengths, and is intended for use with all legally Femoral Continuum Hip System marketed Components with a 12/14 locking taper.

No
The document describes a ceramic femoral head, a mechanical implant, and makes no mention of AI, ML, image processing, or any software-driven functionality.

Yes
The device is intended to treat hip problems, including severely disabled joints, fractures, and failed hip replacements, which points to a therapeutic purpose.

No

The device is a ceramic femoral head, intended for use as an implant in total hip procedures to treat various hip problems. It is a treatment device, not one that identifies or analyzes medical conditions.

No

The device description explicitly states it is a "ceramic femoral head," which is a physical 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. These tests are performed outside of the body.
  • Device Description: The Implex Alumina Femoral Head is a ceramic implant designed to be surgically placed inside the body to replace the femoral head in a hip joint.
  • Intended Use: The intended use clearly describes its function as an articulating component in total hip procedures to address various hip conditions. This is a surgical implant, not a diagnostic test.

The information provided about the device's mechanical testing further supports that it's a physical implant and not a diagnostic tool.

§ 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.

Substantial Equivalence:

The term "substantial equivalence" as used in this 510(k) notification is limited to the definition of substantial equivalence found in the Federal Food, Drug and Cosmetic Act, as amended and as applied under 21 CFR 807, Subpart E under which a device can be marketed without premarket approval or reclassification. A determination of substantial equivalency under this notification is not intended to have any bearing whatsoever on the resolution of patent infringement suits or any other patent matters. No statements related to, or in support of equivalence herein shall substantial be construed as an admission against interest under the US Patent Laws or their application by the courts.

  • Device Description: The Implex Alumina Femoral Head is a ceramic femoral head. The Implex Alumina Femoral Head is offered in a 28 mm OD with +0, +3, and +6 neck offset lengths, and is intended for use with all legally Femoral Continuum Hip System marketed Components with a 12/14 locking taper.
