The document describes a set of orthopedic implants (stems and shells) and their coating, with no mention of software, algorithms, or any technology that would typically incorporate AI/ML. The description focuses on the physical characteristics and intended use of the implants.
Yes
The device is used for the reconstruction of the proximal femur and acetabulum, which is a therapeutic purpose.
No
Explanation: The device is described as an implant (prosthesis) for reconstruction, not a tool for diagnosis.
No
The device description clearly indicates that the device is a physical implant (stem and shells) used in surgical reconstruction, not a software-only product.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "primary ingromented reconstruction of the proximal femur and acetabulum". This describes a surgical implant used in the body, not a test performed on samples taken from the body.
- Device Description: The description details a surgical implant (stems and shells) used for bone reconstruction.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting markers, or providing diagnostic information.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device is a surgical implant used for structural support and reconstruction.

Device Description
The Howmedica® Asymmetric Stem, Vitalock® Cluster & Spiked Shells, and Acetabular Shells with Mesh Ingrowth Surface with Peri-Apatite™ Coating are intended to be used in the primary uncemented reconstruction of the proximal femur and acetabulum. These devices are identical to the previously cleared Asymmetric Stem, Vitalock® Cluster Shell, Vitalock® Spiked Shell and Mesh Shells, except for the presence of a thin layer of hydroxyapatite coating applied to the porous coated surface.
The Peri-Apatite™ coating is the same coating previously characterized and cleared in 510(k) K971206.

§ 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)

The Peri-Apatite™ coating is the same coating previously characterized and cleared in 510(k) K971206.
The substantial equivalence of these devices is based on an equivalence in intended use, materials, design, and relative indications and contraindications to Howmedica's Meridian® ST Stem and Vitalock® Solid Back Shell with Peri-Apatite™ Coating (K971206), Asymmetric Stem (K955871), Vitalock® Cluster Shell (K933102), Vitalock® Spiked Shell (K953664), and Mesh Ingrowth Shells (K973163).

Dear Mr. Maas:
We have reviewed your Section 510(k) notification of intent to market the devices referenced above and we have determined the devices are substantially equivalent (for the indications for use stated in the enclosure) to 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). This decision is based on consideration of the specific design of stem and coating composition detailed in this application. You may, therefore, market the device, subject to the general controls provisions of the Act and the following limitation:
You may not label or in any way promote these devices for "enhanced clinical or radiographic performance, enhanced biological fixation and/or long-term stable fixation." The data presented support equivalence with no additional claims over a conventional porous coated hip prosthesis (i.e., biological fixation only).
Additional limitations for more specific claims of safety and effectiveness may be forthcoming. Should additional limitations be applied you will be contacted in writing to inform you of the additional labeling limitations.
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.

You may market your device under the above limitations as class II devices. These devices would be considered not substantially equivalent to a legally marketed predicate device if labeled with other intended uses and/or claims of safety or effectiveness. Any other intended uses or claims may cause the device to be classified into Class III under Section 513 (f) of the Act. Class III devices are required to have an approved premarket approval (PMA) application prior to marketing.
Existing major requlations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to A substantially equivalent determination assumes 895. compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. In addition, FDA may publish further announcements concerning this your device in the Federal Reqister. Please note: response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Requlations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification immediately. An FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance
