No
The document describes a physical medical device (an acetabular shell) and its materials and intended use, with no mention of software, algorithms, or AI/ML capabilities.
Yes
The device is intended to "alleviate pain and restore function," which are therapeutic outcomes for painful, disabling joint disease.
No
The device description and intended use indicate that the Tritanium Acetabular Shell is an implantable medical device used in hip arthroplasty to restore function and alleviate pain, rather than to diagnose a condition.
No
The device description clearly states it is a "hemispherical acetabular shell," which is a physical implant, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for use in "primary and revision total hip arthroplasty to alleviate pain and restore function." This is a surgical procedure performed directly on the patient's body.
- Device Description: The description details a physical implant (an acetabular shell) designed to be surgically placed in the hip joint.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are used outside the body to analyze samples. This device is an implantable medical device used inside the body during surgery.
N/A
Intended Use / Indications for Use
The Tritanium Acetabular Shell is a sterile, single-use device intended for use in primary and revision total hip arthroplasty to alleviate pain and restore function.
Indications:
-
- Painful, disabling joint disease of the hip resulting from: non-inflammatory degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis, or late stage avascular necrosis.
-
- Revision of previous failed femoral head replacement, shell arthroplasty or other procedure.
- Clinical management problems where arthrodesis or alternative reconstructive 3. techniques are less likely to achieve satisfactory results.
-
- Where bone stock is of poor quality or inadequate for other reconstructive techniques as indicated by deficiencies of the acetabulum.
This acetabular shell is intended for cementless use only.

Device Description
The Tritanium® Acetabular Shell consists of a hemispherical acetabular shell in both solid-backed and cluster screw-hole design and is compatible with all polyethylene Trident inserts. Both shell designs will be available in sizes 44-72 mm outside diameter (OD) in 2 mm increments. The Trident shell is being modified to include a proprietary porous coating, Particle Sintered Foam. The particle sintered foam (PSF) porous metal technology offers net-shape coatings on acetabular shells from which devices can be fabricated.

§ 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)
