The summary focuses on a modification to the porous coating of existing hip stems and does not mention AI or ML.
Yes
The device, a hip stem for joint replacement, is intended to treat and alleviate disability caused by various degenerative joint diseases and correct functional deformities.
No
The provided text describes a hip stem and its coating, which is a prosthetic device used for joint replacement due to degenerative conditions or fractures. It is a treatment device, not a diagnostic one.
No
The device description clearly states it is a modification to existing hip devices, specifically an additional method of porous coating. This indicates a physical component, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes a surgical implant for joint replacement, addressing conditions like osteoarthritis, rheumatoid arthritis, and fractures. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The device is a hip stem, which is a physical implant.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing information about a patient's health status, diagnosis, or disease progression based on sample analysis.
- Reagents, calibrators, or controls used in laboratory testing.
IVDs are used to perform tests on samples taken from the body to provide diagnostic or other information. This device is a physical implant placed into the body for structural support and function.
N/A
Intended Use / Indications for Use
Joint replacement is indicated for patients suffering from disability due to:
- noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis of the natural femoral head.
- rheumatoid arthritis;
- correction of functional deformity;
- femoral fracture
These devices may also be indicated in the salvage of previously failed surgical attempts.
Both the Revelation and Linear hip stems are designed for a cementless application.

§ 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)

Dear Ms. Hutto:
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 (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 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.
