Intended Use
The Aequalis Reversed Shoulder Prosthesis is indicated for patients, with a functional deltoid muscle, as a total shoulder replacement for the relief of pain and significant disability following arthropathy associated to massive non repairable rotator cuff-tear. This device is also indicated for the prosthetic revisions with massive and non repairable rotator cuff-tear. The Aequalis Reversed Shoulder Prosities humeral component is intended for cemented use only and the glenoid component is intended for non cemented use with 4 screws for fixation. When during the primary surgery the glenoid stock appears to be insufficient to bear the reversed glonoid components or when glenoid bone fracture occurs during the surgical procedures, the hemi-prosthesis adaptor and the union screw can be adapted to the humeral components in order to transform the Reversed prosthesis in to a non reversed hemi-prosthesis. When, in case of revision of a Reversed prosthesis, the glenoid bone stock appears to be insufficient to again implant a base plate and a sphere of Reversed range, the use of the hemi-prosthesis adaptor and the union screw allows for the transformation of the Reversed prosthesis in to an anatomical non reversed hemiprosthesis in order to avoid the revision of the humeral components.
Device Description
The Aequalis Reversed Shoulder Prosthesis is intended to relieve pain and significant disability following massive and non repairable cuff-tear associated to arthropathy and following massive cuff-tear arthropathy. In this case, the rotator muscles of the shoulder (supraspinatus, teres pinor and long head of the biceps) are no more useful for mobility, and only the deltoid (for abduction and external rotation) and the subscapularis (for internal rotation) are functional. Therefore, the usual goal of such surgery is to restore the shoulder joint to facilitate its working condition and to reduce or eliminate pain. The Aequalis Reversed Shoulder Prosthesis is intended to accomplish these goals. Its reversed design allows to mcdialize the center of rotation of the shoulder, lengthening the deltoid muscle lever arm. The Aequalis Reversed Shoulder Prosthesis is a semi-constrained system composed of a humeral and a glenoid parts. The present device modification submission consists in the addition of components to the Aequalis Reversed Soulder prosibesis in order to have the possibility to transform the Aequalis Reversed Soulder Prosthesis in a standard hemi or total prosthesis in some clinical cases encountered during the surgical procedure. The present Device Modification submission corresponds to the addition of 3 components of the Aequalis Reversed Shoulder prosthesis: - Hemi-prosthesis adaptor diameter 36 mm, - - Hemi-prosthesis adaptor diameter 42 mm, - - Adaptor metaphysis union screw.
More Information

No
The document describes a mechanical shoulder prosthesis and its components, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is a prosthesis intended to relieve pain and disability, which aligns with the definition of a therapeutic device.

No

The device is a shoulder prosthesis, an implant used in surgery to replace a joint, not to diagnose a condition.

No

The device description clearly states it is a "semi-constrained system composed of a humeral and a glenoid parts" and describes physical components like "Hemi-prosthesis adaptor" and "Adaptor metaphysis union screw." This indicates a physical implant, not a software-only device.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The Aequalis Reversed Shoulder Prosthesis is a physical implant designed to replace a damaged shoulder joint. It is surgically implanted into the patient's body.
  • Intended Use: The intended use describes the surgical implantation of the device to relieve pain and disability in patients with specific shoulder conditions.

The device is a surgical implant, not a diagnostic test performed on samples outside the body.

Identification. A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)

Dear Ms. Lemery:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Device Name: Aequalis Reversed Shoulder Frosthesis

Indications For Use:

The Aequalis Reversed Shoulder Prosthesis is indicated for patients, with a functional deltoid muscle, as a total shoulder replacement for the relief of pain and significant disability following arthropathy associated to massive non repairable rotator cuff-tear. This device is also indicated for the prosthetic revisions with massive and non repairable rotator cuff-tear.

The Aequalis Reversed Shoulder Prosities humeral component is intended for cemented use only and the glenoid component is intended for non cemented use with 4 screws for fixation.

When during the primary surgery the glenoid stock appears to be insufficient to bear the reversed glonoid components or when glenoid bone fracture occurs during the surgical procedures, the hemi-prosthesis adaptor and the union screw can be adapted to the humeral components in order to transform the Reversed prosthesis in to a non reversed hemi-prosthesis.

When, in case of revision of a Reversed prosthesis, the glenoid bone stock appears to be insufficient to again implant a base plate and a sphere of Reversed range, the use of the hemi-prosthesis adaptor and the union screw allows for the transformation of the Reversed prosthesis in to an anatomical non reversed hemiprosthesis in order to avoid the revision of the humeral components.
