The summary describes a mechanical shoulder joint replacement system and its components. There is no mention of software, algorithms, image processing, or any terms related to AI or ML. The performance studies are mechanical wear and fatigue tests.
Yes.
The device is a replacement for shoulder joints intended to increase mobility, stability, and relieve pain in patients suffering from various conditions like arthritis, avascular necrosis, and fractures, which aligns with the definition of a therapeutic device designed to treat or alleviate a medical condition.
No
Explanation: The Aequalis Ascend Flex Shoulder System is a shoulder joint replacement system, used as an implant for treating various shoulder conditions, not for diagnosing them. It is a therapeutic device.
No
The device description clearly outlines physical components made of titanium, CoCr, and UHMWPE, which are implanted into the body. This is a hardware medical device, not software-only.
Based on the provided text, the Aequalis Ascend Flex Shoulder System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the device is a replacement for shoulder joints in patients. This is a surgical implant, not a device used to examine specimens derived from the human body for the purpose of providing information for diagnosis, monitoring, or compatibility testing.
- Device Description: The description details the components of a shoulder prosthesis (stems, heads, glenoids, screws), which are surgically implanted devices.
- Performance Studies: The performance studies described are non-clinical tests related to the mechanical properties and wear of the implant components, not studies on the diagnostic performance of a test.
IVD devices are used in vitro (outside the body) to analyze samples like blood, urine, or tissue. The Aequalis Ascend Flex Shoulder System is an in vivo (inside the body) device used for surgical replacement of a joint.
N/A
Intended Use / Indications for Use
The Aequalis Ascend Flex Shoulder System is intended for use as:
- A replacement of shoulder joints in primary anatomic or in primary reverse.
- A replacement of other shoulder joints devices in case of revisions if sufficient bone stock remains.
- The Aequalis Ascend Flex Shoulder System also allows for conversions from anatomic to reverse shoulder prosthesis in case of revision.
IN ANATOMIC: The stem and head by themselves, as a hemiarthroplasty, if the natural glenoid provides a sufficient bearing surface, or in conjunction with the glenoid, as a total replacement.
The Aequalis Ascend Flex Shoulder System is to be used only in patients with an intact or reconstructable rotator cuff, where it is intended to provide increased mobility and stability and to relieve pain.
The Aequalis Ascend Flex Shoulder System is indicated for use as a replacement of shoulder joints disabled by:

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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).

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.

- 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.
