No
The device description and performance studies focus on the material properties and mechanical performance of ceramic femoral heads, with no mention of AI or ML.
Yes
The device is intended for the treatment of patients requiring total or partial hip arthroplasty, specifically to replace the damaged hip joint, reduce pain, and increase patient mobility, which are all therapeutic functions.
No
Explanation: The device is described as ceramic femoral heads intended for mechanical fixation to a hip stem for hip arthroplasty, which is a treatment, not a diagnostic procedure.
No
The device description clearly states it is a ceramic ball head made of physical materials (alumina, zirconia, chromium oxide) intended for mechanical fixation, indicating it is a physical medical device, not software.
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 device is for "mechanical fixation to a mating hip stem and indicated for treatment of patients who are candidates for total or partial hip arthroplasty". This describes a surgical implant used in vivo (within the body) to replace a damaged joint.
- Device Description: The description details a "ceramic ball head" made of specific materials, designed to "mate with a 12/14 stem taper". This is a physical component of a hip replacement system.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or treatment. IVDs are typically used in vitro (outside the body) for testing purposes.
The device described is a surgical implant, specifically a component of a hip replacement system.

Device Description
The MectaCer Biolox Delta Heads are ceramic ball heads intended for mechanical fixation to a mating hip stem and indicated for the treatment of patients who are candidates for total or partial hip arthroplasty to provide increased patient mobility and reduced pain by replacing the damaged hip joint, in primary or revision surgery. The MectaCer Biolox Delta Heads are an aluminum oxide matrix composite ceramic consisting of approximately 75% alumina (Al₂O₃), 24% zirconia (ZrO₂) and other trace elements. The pink color is due to the chromium oxide (Cr2O3) that improves the hardness of the composite material. The MectaCer Biolox Delta Heads are designed to mate with a 12/14 stem taper. The MectaCer Biolox Delta Heads are available in head diameters of 28, 32, 36, 40, and 44 mm and in neck lengths of Small, Medium, Large, and Extra Large.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The MectaCer Biolox Delta and Forte Heads were tested as part of design verification to written protocols with pre-defined acceptance criteria. The Burst Test, Fatigue Test, Post-Fatigue Test, Rotational Stability Test, and Pull-Off Test were conducted. The testing met all acceptance criteria and verifies that the performance of the MectaCer Biolox Delta Femoral Heads would be adequate for anticipated in vivo loading and that the MectaCer Biolox Forte Heads remain worst-case in comparison to the MectaCer Biolox Delta Heads.

(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)

Comparison to Predicate Devices
The MectaCer Biolox Delta Heads are substantially equivalent to K073337 Medacta MectaCer BIOLOX® forte Femoral Heads, K071535 Zimmer BIOLOX delta Ceramic Femoral Head, K083762 Smith & Nephew Biolox Delta Ceramic Femoral Heads, and K100412 Smith & Nephew Biolox Delta Ceramic Femoral Heads - large sizes. The MectaCer Biolox Delta Heads have the same indications for use as the MectaCer Forte Femoral Heads. The MectaCer Biolox Delta Heads have the same material as the Biolox Delta Heads cleared under K071535, K083762, and K100412. The MectaCer Biolox Delta Heads have the same head diameters as all of the predicate devices (28,32,36mm of the MectaCer Forte Heads; 28,32,36,40mm of the Zimmer Delta Heads; and 28,32,36,40,44mm of the Smith & Nephew Delta Heads). The MectaCer

Biolox Delta Heads have the same neck lengths (S, M, L) as all of the predicate devices and also have the same XL neck length as the Zimmer Biolox Delta Heads.
Performance Testing
The MectaCer Biolox Delta and Forte Heads were tested as part of design verification to written protocols with pre-defined acceptance criteria. The protocols and pre-defined acceptance criteria were based on standards and FDA guidance. The testing was conducted on the worst case size MectaCer Biolox Delta and Forte Heads. The test on the Ti6Al7NB (ISO 5832-11) taper covers compatibility with Medacta's Quadra S (K072857), Quadra H (K082792), Quadra R (K082792), Quadra S-H/SN (K093944), and AMIStem H (K093944) femoral stems. The test on the High Nitrogen Stainless Steel (ISO 5832-9) taper covers compatibility with Medacta's Quadra C (K083558), Quadra C SN (K103189), and AMIStem C (K103189) femoral stems. The testing met all acceptance criteria and verifies that the performance of the MectaCer Biolox Delta Femoral Heads would be adequate for anticipated in vivo loading and that the MectaCer Biolox Forte Heads remain worst-case in comparison to the MectaCer Biolox Delta Heads.
The Burst Test was a compression test made under smooth load with a constant rate of 2mm/min according to ISO 7206-10 (ISO 7206-10: Implants for surgery – Partial and total hip joint prostheses – Part 10: Determination of resistance to static load of femoral heads). The ball is placed on a conical bearing simulating the stem. The modular connection between the ball and the stem of a hip prosthesis is loaded until failure.
The Fatigue Test was made according to CeramTec test procedure AA 02 10 0807. The ball is placed on a conical bearing simulating the stem. The modular connection between the ball and the stem of a hip prosthesis is loaded with a sinusoidal axial force at 10 million cycles.
The Post-Fatigue Test was a compression test made under smooth load with a constant rate of 2mm/min according to ISO 7206-10 (ISO 7206-10: Implants for surgerv - Partial and total hip joint prostheses - Part 10: Determination of resistance to static load of femoral heads). The modular connection between the ball and the stem of a hip prosthesis is loaded until failure after the fatigue test.
The Rotational Stability Test or "torsion test" followed the test description according to the Ceramtec procedure VP-KU-0180. A modular fitting between ball and stem is subjected to frictional torsion until movement occurs.
The Pull-Off Test was made in compliance with the test description of the CeramTec procedure VP-KU-0210, but with 5 samples according to the FDA recommendations. This test corresponds to ISO 7206-10. The femoral head is pressed onto a taper using an axial force of 2 kN and pulled off axially using a loading rate of 1mm/min.

A review of the mechanical data indicates that the MectaCer Biolox Delta Heads are equivalent to devices currently cleared for use and are capable of withstanding expected in vivo loading without failure.
Conclusion:
Based on the above information, the MectaCer Biolox Delta Heads can be considered as substantially equivalent to its predicate devices.
