No
The device description focuses on material, design, and compatibility with existing components, with no mention of AI or ML. The performance studies are based on mechanical testing, not algorithmic performance.
Yes
Explanation: The device is indicated for reduction or relief of pain and/or improved hip function in skeletally mature patients with various hip conditions, which aligns with the definition of a therapeutic device.
No
This device is a hip implant, specifically a femoral head for hip replacement surgery. Its intended use is to reduce or relieve pain and improve hip function in skeletally mature patients with certain hip conditions, not to diagnose them.
No
The device description clearly states it is a physical implant made from CoCrMo alloy, an extension of previously cleared hardware components for hip replacement.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for hip replacement, addressing painful and disabling joint conditions. This is a therapeutic intervention, not a diagnostic test performed on samples outside the body.
- Device Description: The device is described as a femoral head component made of CoCrMo alloy, intended to be used with other components of a hip replacement system. This is a physical implant.
- Lack of IVD characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information.
Therefore, this device falls under the category of a surgical implant or prosthesis, not an In Vitro Diagnostic device.

Device Description
This device manufactured from CoCrMo alloy (ASTM F1537) is an extension of cleared "UNITED" U2 Acetabular Cup and Femoral Head (K022520) and "UNITED" U2 Hip System (K111546). The material, design, safety and effectiveness of this subject are identical to the previously cleared femoral heads except for its offset. The previously cleared femoral head offsets for the U2 Hip System are -3, +0, +5, and +10 mm. This submission adds +7.5 and +2.5 mm offset heads for 28, 32 and 36 mm diameter sizes. This device is intended to be used with the previously cleared U2 Acetabular Cup Liner (K050262), U2 XPE Liner (K111546), U2 bipolar implant (K101670), Revision Stem (K062978), HA/Ti Plasma Spray Stem (K003237), Ti Porous Coated Stem (K003237), UTF Stem (K110245), Press-fit Stem (K111546) and Cemented Stem (K111546) in corresponding size. The differences of femoral head offset do not affect the intended use of the device or alter the fundamental scientific technology of the 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)
