Yes

The device is a shoulder replacement system intended to provide increased mobility and relieve pain, which aligns with the purpose of a therapeutic device.

No

The device is a shoulder replacement system intended to provide increased mobility and relieve pain by replacing disabled shoulder joints. It is a therapeutic device, not a diagnostic one.

No

The device description clearly lists physical components made of materials like Titanium, CoCr, and UHMWPE, indicating it is a hardware medical device (a shoulder implant system).

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Device Description: The AETOS Shoulder System is described as a collection of implants (humeral stem, head, glenoid, liner, baseplate, screws, etc.) made of materials like Titanium and CoCr. These are physical components designed to be surgically implanted into the body.
  • Intended Use: The intended use is to replace shoulder joints disabled by various conditions, providing increased mobility and relieving pain. This is a therapeutic intervention, not a diagnostic test performed on samples.

The description clearly indicates a surgically implanted prosthetic device, which falls under a different category of medical devices than IVDs.

| Technological
Similarities and
Differences
Compared to
Predicate | The subject submission represents line extensions to the AETOS
Shoulder System as follows:

AETOS +15 Full Wedge Baseplates
AETOS +15 Full Wedge Baseplates have the same intended use as
predicate AETOS baseplates: to resurface glenoid bone as part of
reverse total shoulder arthroplasty. Like predicate AETOS baseplates,
AETOS +15 Full Wedge Baseplates are manufactured from Ti6Al4V
and have an unalloyed titanium plasma spray coating as well as screw and post features for uncemented fixation. Like all AETOS
baseplates, AETOS +15 Full Wedge Baseplates mate with compatible
glenospheres via peripheral taper. AETOS +15 Full Wedge
Baseplates have the same centered configuration, diameter, screw-
hole configuration, and post extension compatibility as predicate
augmented AETOS baseplates but differ in that they provide an
additional five degrees of augmentation. AETOS +15 Full Wedge
Baseplate components use packaging configurations and sterilization
processes identical to cited predicates.

AETOS 38mm +3mm Eccentric Glenospheres
AETOS 38mm +3mm Eccentric Glenospheres have the same
intended use as predicate AETOS glenospheres: to provide a
spherical surface for articulation with AETOS Shoulder System
humeral liners as part of a reverse shoulder implant construct. Like
predicate AETOS glenospheres, AETOS 38mm +3mm Eccentric
Glenospheres are manufactured from CoCrMo and attach to
compatible baseplates with a retainer and screw manufactured from
Ti6Al4V. AETOS 38mm +3mm Eccentric Glenospheres have the
same articulating radius, lateralization, and eccentricity as predicate
AETOS 42mm +3mm Eccentric Glenospheres but differ in that they
feature a smaller diameter. AETOS 38mm +3mm Eccentric
Glenospheres use packaging configurations and sterilization
processes identical to cited predicates.

AETOS Reverse Humeral Spacers
AETOS Reverse Humeral Spacers have the same intended use as
predicate and reference humeral spacers: to provide a method for
lateralizing reverse shoulder arthroplasty implant constructs on the
humeral side by introducing additional material between humeral stems and humeral liners. Like predicate Tornier PerFORM humeral |
| | spacers, AETOS Reverse Humeral Spacers are manufactured from
Ti-6Al-4V, provide 9mm of thickness, are available in two sizes, and
mate with compatible stems via Morse taper. AETOS Reverse
Humeral Spacers differ from predicate and reference devices in that
compatibility with humeral stems on the distal aspect and
compatibility with humeral liners on the proximal aspect require
connection geometry specific to their respective systems. Like
predicate Tornier PerFORM humeral spacers, AETOS Reverse
Humeral Spacers are provided sterile via gamma irradiation. |
| Conclusion | Substantial equivalence of the AETOS Shoulder System to cited
predicates can be demonstrated based on the following:
The subject and predicate devices have the same intended use
and similar or the same Indications for Use. The subject and predicate devices share similar functional and
technological characteristics via the same operational
principles. The subject and predicate devices are made from the same
materials and packaged and sterilized using the same methods. Bench testing supports that any minor dimensional differences
between subject and predicate devices do not introduce or exacerbate
any potential issues of safety and effectiveness. As a result Smith &
Nephew concludes the subject AETOS Shoulder System Line
Extensions are substantially equivalent to cited predicate devices. |
