The 510(k) summary describes a mechanical orthopedic implant (femoral stem) and its testing for mechanical properties, biocompatibility, and MRI safety. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities.
Yes.
The device is a hip implant (femoral stem) used in total or partial hip replacement surgeries, which aims to alleviate pain, restore function, and treat various conditions of the hip joint.
No
Explanation: The device described is a femoral stem for hip replacement surgery, which is an implanted prosthetic device used for treatment, not for diagnosis.
No
The device description clearly states that the device is a physical femoral stem, which is a hardware component used in hip arthroplasty. The summary details physical testing and biocompatibility evaluations, further indicating it is not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended use clearly describes the device as a component for total and partial hip replacement surgery, addressing conditions like osteoarthritis, fractures, and avascular necrosis. This is a surgical implant, not a diagnostic test performed on biological samples.
- Device Description: The description details the physical components of a femoral stem used in hip arthroplasty. This is a medical device designed for implantation, not for analyzing samples.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening. The performance studies focus on mechanical properties, biocompatibility, and MRI safety, which are relevant to surgical implants, not IVDs.
Therefore, this device falls under the category of a surgical implant or prosthesis, not an In Vitro Diagnostic device.

Device Description
The EMPHASYS Femoral Stems include HA-coated femoral stems in standard and high offsets and in collared and collarless configurations. The EMPHASYS Femoral Stems are designed to be used as one component of a system of prostheses in hip arthroplasty. The stems are compatible with a DePuy modular metal, dual mobility, or ceramic femoral head, and either a one-piece or a metal-backed two-piece acetabular component for use in total hip arthroplasty, and with a modular unipolar metallic femoral head or a modular bipolar head construct for hemi-hip arthroplasty.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Testing and engineering analyses were performed on the EMPHASYS Femoral Stems to demonstrate substantial equivalence of safety and efficacy with the predicate device, addressing:
- Neck Fatigue (to ISO 7206-6: 2013) .
- Distal Stem Fatigue (to ISO 7206-4: 2010) .
- Range of Motion (to BS EN ISO 21535: 2009) .
- Taper equivalence
Biocompatibility evaluation was carried out to ISO 10993-1:2018 and testing was carried out to include genotoxicity to ISO 10993-3:2014, cytotoxicity to ISO 10993-5:2009, sensitization to ISO 10993-10:2010, pyrogenicity to ISO 10993-11:2017 and chemical characterization to ISO 10993-18:2020.
The proposed devices also meet the requirement of bacterial endotoxin testing as specified in ANSI/AAMI ST 72:2019.
Magnetic Resonance Imaging safety evaluation testing was performed following ASTM F2503-13, and the tests evaluated the worst-case components and constructs for magnetically induced force (ASTM F2213-17), image artefact (ASTM 2119-07 (reapproved 2013)) and RF heating (ASTM F2182-19). The testing concluded that there are no safety issues related to magnetic field interactions under specific conditions identified in the labelling.
Hydroxyapatie characterization data, as recommended in the FDA Guidance 510(k) Information needed for Hydrosyapatite coated Orthopedic Implants, is provided.
No clinical tests were conducted to demonstrate substantial equivalence. The subject EMPHASYS Femoral Stems are substantially equivalent to the predicate CORAIL AMT Hip Prosthesis.

§ 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.

SUMMARY OF THE TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICE
The subject EMPHASYS Femoral Stems are similar to the predicate CORALL AMT Hip Prosthesis (K042992, K123960, K190344) in intended use, indications for use, design. The subject and predicate systems are intended for total or hemi hip arthroplasy and have the same indications for use. Both are forged titanium alloy. HA coated stems for uncemented use with a taper. Both devices have the same size tapers, and both are offered in collaress, standard offset and high offset configurations. Both devices are used in a modular hip construct which includes DePuy femoral head and acetabular components. The design of the subject and predicate devices is similar in terms of shape and function the intraosseous geometry of the subject devices has a narrower ML profile in places and is shorter than the predicate stems. The subject devices are offered in a 130° neck angle that is in between the two angles offered by the predicate devices.
