Device Description
For E-XPE Acetabular Components The subject E-XPE Acetabular Components includes U-Motion II E-XPE Cup Liner and E-XPE Cemented Cup. U-Motion II E-XPE Cup Liner includes 0° and 20° hood designs, which are available in 28 mm, 32 mm, 36 mm and 40 mm inner diameter (ID). The 28 mm liners fit the acetabular cups with outer diameter (OD) ranging from 44-46 mm, the 32 mm liners fit the acetabular cups ranging from 46-50 mm, the 36 mm liners fit the acetabular cups ranging from 50-70 mm, and the 40 mm liners fit the acetabular cups ranging from 56-70 mm. The E-XPE Cemented Cup is design for cemented use and assembled with a PMMA Spacer and an X-ray marking wire. The cement mantle is built within the outer surface of acetabular cup. The PMMA Spacer is designed for cement fixation with a uniform cement thickness and the X-ray marking wire is designed for X-ray image identification purpose. E-XPE Cemented Cups are available in a range of sizes to fit varying anatomical requirements. For U-Motion II Acetabular Cup The indication for use, materials, cup hole types, size distribution, sterilization method, safety and effectiveness of subject device are identical to predicate device (K122185) except the locking design. The subject device are available in sizes from 44 mm through 80 mm outer diameter in 2 mm increments.
More Information

No
The device description and performance studies focus on the mechanical properties and design of hip replacement components, with no mention of AI or ML.

Yes

The device, an acetabular component for hip replacement, is intended for "reduction or relief of pain and/or improved hip function," which are therapeutic outcomes.

No

The device description clearly states it is an implant for hip replacement, designed to reduce pain and improve hip function by correcting deformity or treating painful joint diseases and fractures. The document also describes mechanical tests (locking strength, impingement, wear simulation, material properties) and mentions "X-ray marking wire" for "X-ray image identification purpose" which points to it being an intervention, not a diagnostic tool.

No

The device description clearly details physical components (cup liner, cemented cup, PMMA spacer, X-ray marking wire) and performance testing related to mechanical properties and wear, indicating it is a physical implant, not software.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes the device as an implant for surgical procedures to treat hip joint conditions. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
  • Device Description: The description details the physical components of an artificial hip joint (liners and cups) designed for implantation.
  • Performance Studies: The performance studies focus on mechanical properties, wear simulation, and material properties relevant to an implantable device, not on the accuracy or reliability of a diagnostic test.

IVD devices are used to examine specimens (like blood, urine, or tissue) from the human body to provide information for diagnosis, monitoring, or screening. This device is a surgical implant used to replace or augment a damaged hip joint.

§ 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.

Comparison to Predicate Device:

For E-XPE Acetabular Components

The features of the subject devices are comparable to the predicate devices in terms of the same design, indication for use, locking mechanism and sterilization method expect material and size distribution. In material respect, the subject U-Motion II E-XPE Cup Liner is made from highly cross-linked Vitamin E UHMWPE (E-XPE) which is different from highly cross-linked UHMWPE (XPE) used for "UNITED" U-Motion II Acetabular System (K122185) but is substantially equivalent to "Corin" Trinity Acetabular System ECIMA Liners (K111481) and "Encore" X-alt™ Highly Cross Linked Acetabular Liner with Vitamin E (K130365). The subject E-XPE Cemented Cup is made from E-XPE, PMMA and Co-20Cr-15W-10Ni. These materials are identical with those used for "UNITED" Full XPE Cup (K163441) except E-XPE material. The size distribution of the subject devices is within the size range of "UNITED" U-Motion II Acetabular System (K122185) and "UNITED" Full XPE Cup (K163441). The differences between subject and predicate devices would not pose issues about safety and effectiveness. Non-clinical tests were also performed and the tests results demonstrate that the subject devices are substantially equivalent to the predicate devices.

For U-Motion II Acetabular Cup

The features of the subject devices are comparable to the predicate devices (K050262, K122185) in terms of the indication for use, materials, and sterilization method except the locking design and size distribution. The differences between the subject devices and predicate devices have been validated by locking strength testing to demonstrate that the subject U-Motion II Acetabular Cup does not introduce new risk of safety and effectiveness.
