No
The summary describes a mechanical medical device (total hip arthroplasty components) and its materials and performance testing. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML.
Yes.
The device is indicated for the "reduction or relief of pain and/or improved hip function" and for the "treatment of nonunion femoral neck and trochanteric fracture", which are therapeutic purposes.
No
This device is a total hip arthroplasty system, including acetabular and femoral components, designed for the surgical replacement of hip joints. Its intended use is to relieve pain and improve hip function in patients with painful, disabling joint disease of the hip, not to diagnose medical conditions.
No
The device description clearly details physical components like acetabular cups, femoral heads, screws, and liners, all made of various materials like titanium alloy, UHMWPE, and ceramic. This indicates a hardware medical device, not a software-only one.
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 device used for the treatment of painful and disabling joint disease of the hip, revision of previous procedures, correction of functional deformity, and treatment of certain fractures. This is a therapeutic purpose, not a diagnostic one.
- Device Description: The device is described as a total hip arthroplasty system, including acetabular and femoral components made of various materials. These are implantable medical devices used for surgical replacement of the hip joint.
- Lack of Diagnostic Elements: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
- Performance Studies: The performance studies described are bench tests evaluating the mechanical properties, wear, and locking strength of the components. These are typical tests for implantable devices, not IVDs.
In summary, the device is a surgical implant designed to replace a damaged hip joint, which falls under the category of a therapeutic medical device, not an in vitro diagnostic device.

Device Description
The subject device designed for total hip arthroplasty includes acetabular components and femoral components. The acetabular components are composed of a highly crosslinked ultra - high - molecular - weight - polyethylene articulating bearing surface fixed in a metal shell acetabular cup, while metal shell could be fixed with acetabulum by Ti Cancellous Screw and optional screw hole cover. The femoral component is composed of a ceramic femoral head.
U-Motion II Acetabular Cup includes U-Motion II HA Cup and U-Motion II PS Cup. It is manufactured from titanium alloy forging (ASTM F620) which are forged by titanium alloy bars conforming to ASTM F136. The outer surface of U-Motion II HA Cup is coated with dual coatings, CP Ti powder (ASTM F1580) for the inner layer and HA (ASTM F1185) for the outer layer. The materials of substrate and coating layers are identical to previous cleared "UNITED" U2 Acetabular Component (K050262, K12177). The outer surface of U-Motion II PS Cup is coated with CP Ti power. There are nineteen sizes of acetabular shell available, ranging from 44 through 80 mm outer diameter in 2 mm increments. U-Motion II Cup has a snap fit locking groove for acceptance of the U-Motion II XPE Cup Liner.

Ti Cancellous Screw are self tapping and in a 6.5 mm diameter with length of 15 to 60 mm in 5 mm increments. The designs of screw are identical with the cleared screws (K050262), except for the design of screw head. This subject device also has screws and hole covers available to cover the shell holes if desired. Screw and hole covers are manufactured from Ti-6Al-4V bar (ASTM F136).
U-Motion II XPE Cup Liner is manufactured from highly crosslinked UHMWPE which conforms to ASTM F2565 and the UHMWPE raw material is in accordance with ASTM F648 and ISO 5834. The materials are identical to previous cleared "UNITED" XPE liners of U2 Hip System (K111546). U-Motion II XPE Cup Liner includes 0° and 20° hood designs, which are available in 28 mm. 32 mm. 36 mm and 40 mm inside diameter (ID), The 28 mm inserts fit the acetabular shells with outer diameter (OD) ranging from 44-80 mm, the 32 mm inserts fit the acetabular shells ranging from 48-80 mm, the 36 mm inserts fit the acetabular shells ranging from 52-80 mm, and the 40 mm inserts fit the acetabular shells ranging from 56-80 mm.
40 mm Ceramic Femoral Head - Delta is an additional size extension to the previously cleared "UNITED" Ceramic Femoral Head--Delta (K103497, K112463). The materials, design, safety and effectiveness of this subject are identical to the previously cleared device (available in sizes 28 mm, 32 mm and 36 mm), except for its larger diameter. 40 mm Ceramic Femoral Head - Delta, developed by CeramTec AG, is made from an alumina matrix composite in accordance with ISO 6474-2 and is available in -3, +1, +5 and +9 mm of neck length.
U-Motion II Cup will be used with U-Motion II XPE Cup Liner, 40 mm Ceramic Femoral Head - Delta, previously cleared 28 mm, 32 mm metal Femoral Head (K022520, K111546) and Ceramic Femoral Head (K103479, K112463) in corresponding size. This device should not be used with those of another manufacturer's hip components since the articular and dimensional compatibility cannot be assured. The 40 mm Ceramic Femoral Head may be used with UTF Stem (K110245) and the stems made of titanium alloy in U2 Hip Stem series (K003237, K062978, K111546).

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.
