No
The document describes a physical medical device (an acetabular liner) and its mechanical and material properties. There is no mention of software, algorithms, image processing, or any terms related to AI or ML.
Yes
The device is intended for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function, which falls under the definition of a therapeutic purpose.
No
This device is an acetabular liner for use in total hip arthroplasty, intended to reduce pain and improve hip function. It is a prosthetic implant, not a device used to diagnose a medical condition.
No
The device description clearly states it is a physical acetabular liner made from a specific material (XLPE) and intended for surgical implantation as part of a total hip arthroplasty system. It also details mechanical testing performed on the physical device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for use in total hip arthroplasty for the reduction or relief of pain and/or improved hip function in patients. This is a surgical procedure performed in vivo (within the living body).
- Device Description: The description details a physical implant component (an acetabular liner) designed to be surgically placed in the hip joint.
- Lack of IVD Characteristics: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform any such function.
The information provided describes a medical device intended for surgical implantation, not an in vitro diagnostic test.

§ 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)

To the right of the square is the word "MicroPort" in blue, with the word "Orthopedics" underneath in red. Below that is the phrase "Full Function, Faster" in blue.
C. Substantial Equivalence Information
The subject Liner's intended use, size range, articulating surface, and available configurations are identical to the predicates K171181 and K180798. The subject Liner's material (E-CLASS™) is identical to the predicate K171181. The subject Liner's geometry is identical to the predicate K180798.
The fundamental scientific technology of the subject Liner has not changed relative to the predicates.
Based on these similarities, the Prime E-CLASS™ XLPE Liner is believed to be substantially equivalent to the predicate devices.
D. Nonclinical Testing
Nonclinical testing performed on the to establish the basis for substantial equivalence of the Prime E-CLASS™ XLPE Liner included bacterial endotoxin testing and mechanical testing of the lock detail.
- . Bacterial endotoxin testing was performed per ANSI/AAMI ST72:2011; endotoxins were found to be less than the USP endotoxin limit of 20 EU/device;
- . Mechanical testing of the lock detail was performed through Pre- and Post- Fatigue Pushout Lever-out and Torque-out of the subject Liner from a compatible Shell (K170444; K180798) per ASTM F1820, ASTM STP1301, and testing found in literature. Axial long-term fatigue per FDA Draft Guidance Documents "Guidance Document for Testing Acetabular Cup Prostheses" and "Guidance Document for Testing Non-Articulating 'Mechanically-Locked' Modular Implant Components", both issued May 1, 1995, was also evaluated as part of this study.

- Deformation and frictional torque per ISO 7206-12. ●
Due to the subject Liner's identical articulating surface and configurations, the following testing performed for K170444 is considered applicable:
- Range of motion per ISO 21535 ●
E. Clinical Testing
Clinical data was not necessary to determine substantial equivalence between the Prime E-CLASS™ XLPE Liner and the predicate devices.
F. Biocompatibility
The Prime E-CLASS™ XLPE Liner is manufactured from the identical E-CLASS™ material characterized for the predicate K171181. Intended patient contact also remains identical. Therefore, biocompatibility testing performed for K171181 remains applicable to the subject device. Biocompatibility bench and animal studies used to characterize the E-CLASS™ material included extractables, cytotoxicity, irritation, and sensitization studies.
The Prime E-CLASS™ XLPE Liner is implanted using the same instrumentation cleared within K170444; no new biocompatibility assessment is required.
G. Component and Accessory Compatibility
The Prime E-CLASS™ XLPE Liner is compatible with Prime Acetabular Cup System Shells (K170444; K180798) and Instrumentation (K170444). The Prime E-CLASS™ XLPE Liner is also compatible with previously cleared MicroPort Femoral Heads.
Compatibility of the subject Liner with previously cleared MicroPort Orthopedics is listed in Table 1.

I. Conclusion
The indications for use and fundamental scientific technology of the Prime E-CLASS™ XLPE Liner are identical to the predicate and reference devices. The subject Liner's geometry is identical to the predicate K180798. The subject Liner's material is identical to the predicate K171181. Additionally, the Prime E-CLASS™ XLPE Liner's compatibility with other components is identical to the predicate liners cleared within K171181 and K180798. The predicate and subject testing and analyses support the substantial equivalence of the Prime E-CLASS™ XLPE Liner's performance.
