The summary describes a mechanical hip implant with porous coating for fixation, and mentions only fatigue testing. There is no mention of software, algorithms, or any features that would suggest AI/ML is involved.
Yes
The device is a hip stem used in total hip arthroplasty to treat degenerative joint diseases and other conditions, which is a therapeutic intervention.
No
Explanation: The device described is a hip stem, which is an implant used in total hip arthroplasty to replace a joint. It is a treatment device, not a diagnostic one.
No
The device description clearly states it is a physical hip stem fabricated from titanium with a porous coating, indicating it is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description and Intended Use: The Revelation™ Porous Hip Stem is a surgical implant designed to replace a damaged hip joint. It is implanted directly into the patient's body.
- Lack of Specimen Analysis: The description and intended use do not involve the analysis of any biological specimens outside of the body.
Therefore, the Revelation™ Porous Hip Stem falls under the category of a surgical implant, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Revelation™ Porous Hip Stem is intended for treatment of patients who are candidates for total hip arthroplasty because of degenerative joint disease including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedures where other treatments or devices have failed; and treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques.

Device Description
The Revelation™ Porous Hip Stem is fabricated from wrought/forged or cast Ti-6A1-4V that conforms to ASTM F136 or F1108, respectively. The outside surface of the stem is porous coated with commercially pure titanium (ASTM F67 grade 2) beads to provide a porous surface for enhanced fixation. The Revelation™ Porous Hip Stem is collarless and has a Morse type taper to receive modular heads.

§ 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)
