The summary describes a mechanical implant (femoral head) and its performance testing, with no mention of software, algorithms, or AI/ML capabilities.
Yes
The device is a component of a total hip arthroplasty system, which is explicitly intended for the reduction or relief of pain and improved hip function, thereby providing a therapeutic benefit to patients with various degenerative joint diseases and functional deformities of the hip.
No
This device is described as a component of a total hip system, specifically a femoral head, intended for use in total hip arthroplasty to treat conditions like degenerative joint disease. Its purpose is to replace a damaged anatomical part and restore function, which is a therapeutic rather than a diagnostic function.
No
The device description and performance studies clearly indicate this is a physical medical device (a ceramic femoral head) and not a software-only device. The testing focuses on mechanical properties and MR safety, which are relevant to hardware.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections.
- Device Description: The provided text describes a total hip system, specifically a Ceramic Femoral Head, which is an implantable device used in surgery to replace a damaged hip joint.
- Intended Use: The intended use clearly states it's for total hip arthroplasty to address conditions like osteoarthritis and rheumatoid arthritis, and for revision procedures. This is a surgical intervention, not a diagnostic test performed on a sample.
The information provided focuses on the mechanical properties, materials, and surgical application of the device, which are characteristic of an orthopedic implant, not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Engineering evaluations were conducted to verify that the performance of the Ceramic Femoral Head manufactured from alumina matrix composite (Permallon Tru) is equal to and/or better than the predicate device and therefore adequate for the anticipated in-vivo use. The following V&V activities were conducted:
- Axial compression test
- Fatigue test
- Post-fatigue ultimate compression strength test
- Static pull off test
- Static torsion test
• MR Safety Evaluation per ASTM F2182-19 and FDA Guidance for "Assessment of Radiofrequency-Induced Heating in the Magnetic Resonance (MR) Environment for Multi-Configuration Passive Medical Devices" issued March 2016, ASTM F2052-21, ASTM F2119-07 (reapproved 2013). Results were compared to non-predicate benchmarks.
Non-clinical (mechanical) testing results met the applicable acceptance criteria; therefore, acceptable mechanical performance is expected of the Ceramic Femoral Head manufactured by CoorsTek. Based on comparability of mechanical performance data, the subject device is substantially equivalent to the predicate devices.

§ 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.

DEVICE INFORMATION
A. Intended Use/Indications for Use Statement
MicroPort total hip systems are intended for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:
- non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia;
-
- inflammatory degenerative joint disease such as rheumatoid arthritis;
-
- correction of functional deformity; and,
-
- revision procedures where other treatments or devices have failed.
B. Device Description
The modular Ceramic Femoral Head is composed of alumina matrix composite, manufactured as per ISO 6474-2. It has a 12/14 taper which is identical to the taper on MicroPort Orthopedics' range of femoral heads. The device articulates with an acetabular liner and is compatible for use across any of MicroPort Orthopedics' total hip component range.
C. Substantial Equivalence Information
The indications for use for MicroPort Orthopedics' Ceramic Femoral Head (CoorsTek) remain the same as the indications for use for the MicroPort Orthopedics' Femoral Head (CeramTec) and subject device shares the same indications for use as the Signature Orthopaedics' Signature Ceramic Femoral Head.
The ceramic femoral head (Permallon Tru) manufactured by CoorsTek has the same geometry as the previously cleared ceramic femoral head (Biolox delta) manufactured by CeramTec with identical conical bore which is a 12/14 taper that can accept a MicroPort trunnion having 12/14 taper, in the form of either a monolithic classic hip stem or modular femoral neck.
The femoral head offset and gauge diameter, taper, bore straightness, bore surface roughness, articulating surface roughness, sphericity and defect requirements are identical to the predicate device. There are no significant differences in these technological characteristics between the subject and predicate devices affecting performance or safety.
The only difference compared to the predicate femoral head (BIOLOX delta) is the manufacturing of the Ceramic Femoral Head from alumina matrix composite (Permallon Tru) provided by CoorsTek.
