The Aequalis Ascend Flex Shoulder System is indicated for use as a replacement of shoulder joints for patients with a functional deltoid muscle and with massive and non-repairable rotator cuff-tear. This submission corresponds to the addition of Titanium Humeral Heads in anatomic to the Aequalis™ Ascend™ Flex Shoulder System.
The provided document is a 510(k) Summary for the Aequalis™ Ascend™ Flex Shoulder System, focusing on the addition of Titanium Humeral Heads. This type of regulatory submission demonstrates substantial equivalence to a legally marketed predicate device, rather than proving that a device meets specific acceptance criteria through a comprehensive study in the way an AI/ML device would be evaluated.
Therefore, the requested information, which is typically relevant for AI/ML device evaluations involving clinical performance studies and ground truth establishment, is largely not applicable to this document. The document describes non-clinical (bench) testing to demonstrate mechanical equivalence, not clinical performance or diagnostic accuracy.
However, I can extract the relevant information the document does provide and indicate where the requested information is not present or not applicable.
1. A table of acceptance criteria and the reported device performance
The document does not explicitly define "acceptance criteria" in a quantitative manner as one would for diagnostic accuracy metrics (e.g., sensitivity, specificity thresholds). Instead, "device performance" is demonstrated through non-clinical (bench) testing, showing equivalence to predicate devices under simulated conditions.
| Test Type | Acceptance Criteria (Implicit) | Reported Device Performance |
|---|---|---|
| Wear Test | Titanium humeral head remains intact during its lifetime. Wear of new Ti/UHMWPE frictional couple is equivalent to predicate CoCr/UHMWPE frictional couple. | Equivalent results between Ti/UHMWPE and CoCr/UHMWPE in terms of: weight loss, wear rate, and shape/size of generated particles. |
| Anatomical Fatigue Test | Aequalis™ Ascend Flex Shoulder System (anatomical configuration with Titanium humeral head) remains intact during its lifetime, resisting load for 5M cycles without fracture or damage. | No fracture or damage observed after applying a load for 5 million cycles. Validated with titanium humeral head, similar to CoCr humeral head (predicate). |
| Reversed Fatigue Test | Aequalis™ Ascend Flex Shoulder System (reversed configuration after revision from anatomical to reversed, with Titanium humeral head) remains intact during its lifetime after 5M cycles without fracture or damage. | No fracture or damage observed after applying a load for 5 million cycles. Validated with titanium humeral head, similar to CoCr humeral head (predicate). |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample size for test set: Not applicable in the context of clinical studies for diagnostic AI/ML. The tests mentioned are bench tests on physical devices/components. The sample size would refer to the number of physical samples tested, which is not specified in the summary document but would be detailed in the full test reports.
- Data provenance: Not applicable. The data comes from non-clinical bench testing, not clinical data from patients.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. "Ground truth" in this context is established by the physical testing and material properties, not by expert interpretation of data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This refers to expert consensus for clinical image interpretation, not mechanical testing.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This is for AI/ML diagnostic devices, not shoulder prosthetics.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is for AI/ML diagnostic devices, not shoulder prosthetics.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for these tests are the material properties and mechanical performance under specified conditions, determined by standardized test methodologies (e.g., ISO standards, and documented internal test protocols). The assessment is based on physical observation (e.g., absence of fracture, damage) and quantitative measurements (e.g., wear rate, weight loss), not clinical outcomes or pathology.
8. The sample size for the training set
Not applicable. There is no AI/ML algorithm being trained here.
9. How the ground truth for the training set was established
Not applicable. There is no AI/ML algorithm being trained here.
In summary, this 510(k) submission demonstrates the safety and effectiveness of a medical device (shoulder prosthesis component) through non-clinical (bench) testing, showing its equivalence to legally marketed predicate devices. The framework for describing acceptance criteria and studies for AI/ML devices is not directly applicable to this type of traditional medical device submission.

The indications for use, the technical characteristics (manufacturing principle and method of fixation), the packaging and the sterilization process of they are similar or identical to the predicate devices.
10) Non-clinical testing
Three non-clinical testing were realized on the titanium humeral heads:
- Wear test:
The aim of the test is to demonstrate that the Titanium humeral head remain intact during its lifetime. Therefore, we have tested the wear of the frictional couple Ti / UHMWPE and compared the results with those of the frictional couple CoCr/UHMWPE.
The results of this test are equivalent between the two frictional couples CoCr / UHMWPE (already used in the predicate device "Aequalis Ascend Flex Shoulder System") and TI / UHMWPE in terms of: weight loss, wear rate and shape and size of the particles generated.
Anatomical Fatigue Test:
The aim of the test is to show that the AequalisTM Ascend Flex Shoulder System in anatomical configuration remains intact during its lifetime. The assembly humeral head/ stem must resist in normal conditions of use.
After applying a load for SM cycles, we have observed neither fracture nor damage. Thus, the Aequalis™ Ascend Flex Shoulder System in anatomical configuration is validated with the titanium humeral head as is the case with the CoCr humeral head (predicate device).
Reversed fatique test: -
The aim of the test is to show that the Aequalis™ Ascend Flex Shoulder System in reversed configuration remains intact during its lifetime after revision from an anatomical configuration to a reversed configuration after a first lifetime in an anatomical configuration. The assembly humeral headl stem must resist in normal conditions of use.
After applying a load for SM cycles. we have observed neither fracture nor damage. Thus, the Aequalis™ Ascend Flex Shoulder in reversed configuration after revision from an anatomical configuration to a reversed configuration after a first lifetime in anatomical configuration with the titanium humeral head is validated as is the case with the CoCr humeral head (predicate device).
11) Substantial equivalence conclusion
Substantial equivalence of the Aequalis Ascend Flex Shoulder System titanium humeral heads to the already cleared components of the predicates can be demonstrated on the following grounds, according to the FDA's Guidelines for Substantial Equivalence Decision Making Process:
- The Aequalis Ascend Flex Shoulder System titanium humeral heads are compared to the predicate . devices.
- The Aequalis Ascend Flex Shoulder System Tianium humeral heads have the same intended use and l the same indications for use as the cleared Aequalis Ascend Flex Shoulder System Cobals Chrome humeral heads.
- The Aequalis Ascend Flex Shoulder System titanium humeral heads have equivalent intended use and indications for use as Aequalis Shoulder System Aequalis Humeral Head in titunium.
Tomier
{8}------------------------------------------------
- Major technological characteristics are equivalent between the Aequalis Ascend Flex Shoulder System titanium humeral heuds and the predicate devices:
- Equivalence of general features -
- Equivalent technological features: materials •
- Equivalent biomechanical features: mechanical characteristics, congruence of articular surfaces.
- Equivalent means of fixation (Taper gender geometry) -
- Equivalent prosthetic dimensions -
Therefore, in light of the above information, the company believes that the Aequalis Ascend Flex Shoulder System with itanium humerul heads may be cleared via the 510(k) notification process for use as shoulder prosthesis.
