No
The summary describes a passive, mechanical implant (acetabular shell) and does not mention any computational or analytical capabilities that would suggest the use of AI/ML. The focus is on materials, design, and mechanical testing.
Yes
The device is described as "painful, disabling joint disease of the hip from: degenerative arthritis, rheumatoid arthritis, posttraumatic arthritis or late stage avascular necrosis" and "revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure". These indications point to the device being used to treat or manage a medical condition, which aligns with the definition of a therapeutic device.
No
This device is a surgical implant (acetabular shell) used for total hip arthroplasty, which is a treatment procedure, not a diagnostic one.
No
The device description explicitly states it is a sterile, single-use device manufactured from Ti-6Al-4V ELI alloy with a porous CP-Ti coating, indicating it is a physical implant and not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body.
- Device Description: The provided text describes a "Restoration Anatomic Shell" which is a sterile, single-use device intended for cementless fixation into a prepared acetabulum for Total Hip Arthroplasty. This is a surgical implant used inside the body.
- Intended Use: The intended use clearly describes the treatment of painful and disabling joint diseases of the hip, revision of previous procedures, and addressing bone stock issues. These are all related to surgical intervention and implantation, not laboratory testing of specimens.
The device described is a surgical implant used in orthopedic procedures, not an in vitro diagnostic device.

§ 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)
