The summary describes a physical implant (femoral stem) and its material properties and intended use in hip arthroplasty. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is intended to treat specific medical conditions (e.g., severely painful joints, avascular necrosis, fractures) and replace damaged parts of the hip joint to reduce pain and increase mobility, fitting the definition of a therapeutic device.
No
The device is a femoral stem for hip arthroplasty, which is a surgical implant designed to replace part of a hip joint, not to diagnose a condition.
No
The device description clearly states it is a physical femoral stem made of titanium alloy and coated with HA, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the EMPHASYS Femoral Stems are for use in total and partial hip arthroplasty, which is a surgical procedure to replace a damaged hip joint. This is a therapeutic intervention, not a diagnostic test performed in vitro (outside the body).
- Device Description: The device is described as a femoral stem made of titanium alloy with a HA coating. This is a physical implant, not a reagent, instrument, or system intended for the examination of specimens derived from the human body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, providing diagnostic information, or any other activity typically associated with IVD devices.
Therefore, the EMPHASYS Femoral Stems are a surgical implant, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
SUMMARY OF NON-CLINICAL TESTS CONDUCTED FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE
The subject HA coated EMPHASYS Femoral Stems are manufactured to the same production specifications as the predicate devices (K211657 and K203167). As the subject devices have been validated to be manufactured to the same specifications and utilize the same materials, the shelf life extension will not impact the fit, form or function of these components. Therefore, the nonclinical tests reviewed as part of K211657 and K203167 remain current.
Packaging shelf-life validation has been carried out to confirm a shelf-life of 10 years.
HA coating properties on aged products were tested as per ISO-13779-3 (Crystallinity, Foreign Phases and CaP ratio), ASTM F1854 (Thickness) and ASTM E2109 (Porosity) to confirm a shelf-life of 10 years.
SUMMARY OF CLINICAL TESTS CONDUCTED FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE AND/OR OF CLINICAL INFORMATION
No clinical tests were conducted to demonstrate substantial equivalence.
CONCLUSIONS DRAWN FROM NON-CLINICAL AND CLINICAL DATA
The subject device EMPHASYS Femoral Stems is equivalent to the predicates EMPHASYS Femoral Stems (K211657) and DePuy CORAIL AMT Prosthesis (K203167). There have been no modifications made to the intended use, design, biocompatibility, materials, sterilization or packaging of the existing EMPHASYS Femoral Stems.

§ 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)

PERFORMANCE DATA
SUMMARY OF NON-CLINICAL TESTS CONDUCTED FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE
The subject HA coated EMPHASYS Femoral Stems are manufactured to the same production specifications as the predicate devices (K211657 and K203167). As the subject devices have been validated to be manufactured to the same specifications and utilize the same materials, the shelf life extension will not impact the fit, form or function of these components. Therefore, the nonclinical tests reviewed as part of K211657 and K203167 remain current.
Packaging shelf-life validation has been carried out to confirm a shelf-life of 10 years.
HA coating properties on aged products were tested as per ISO-13779-3 (Crystallinity, Foreign Phases and CaP ratio), ASTM F1854 (Thickness) and ASTM E2109 (Porosity) to confirm a shelf-life of 10 years.
SUMMARY OF CLINICAL TESTS CONDUCTED FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE AND/OR OF CLINICAL INFORMATION
No clinical tests were conducted to demonstrate substantial equivalence.
CONCLUSIONS DRAWN FROM NON-CLINICAL AND CLINICAL DATA
The subject device EMPHASYS Femoral Stems is equivalent to the predicates EMPHASYS Femoral Stems (K211657) and DePuy CORAIL AMT Prosthesis (K203167). There have been no modifications made to the intended use, design, biocompatibility, materials, sterilization or packaging of the existing EMPHASYS Femoral Stems.
