The document describes a mechanical shoulder implant system and its components. There is no mention of software, algorithms, or any technology that would typically incorporate AI or ML. The performance studies focus on mechanical properties and biocompatibility.
Yes
The device is an arthroplasty system intended to replace a severely painful and/or disabled shoulder joint due to various conditions, which directly addresses a medical condition or ailment.
No
The provided text describes a shoulder implant system used for arthroplasty, which is a treatment device, not a diagnostic one. Its purpose is to replace or reconstruct a joint, not to diagnose a condition.
No
The device description clearly outlines physical components like humeral stems, humeral heads, CTA heads, and glenoid components, which are hardware implants for shoulder arthroplasty.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a shoulder system for anatomic total or hemi shoulder arthroplasty. This is a surgical implant used in vivo (within the body) to replace or repair a joint.
- Device Description: The description details the components of a shoulder implant (stems, heads, glenoids) and their materials. These are physical devices implanted during surgery.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used in vitro (outside the body) to analyze samples. This device is an in vivo surgical implant.

Device Description
The LINK Embrace Shoulder System offers diverse fixation options suitable for the majority of patient populations and indications. A wide range of stems in different configurations allows for cemented and cementless fixation.
Humeral Stems (Ti6Al4V) are available in monoblock designs, and feature a proximal modular taper connection for assembly to head adapters. The monoblock Humeral Stems are available in Standard Stems and Short Stems with a broad size spectrum, and in non-coated and Calcium Phosphate coated versions. Humeral Fracture Stems are also available. The Humeral Stems have been previously cleared for use with the LINK Embrace Shoulder System – Reverse [K200368].
Humeral Heads (CoCrMo) are available in several sizes with a female taper for connection to the Head Adapters.
CTA Heads (CoCrMo) are available in neutral and different offset versions and feature a male taper for connection to Humeral Stems.
The Cemented All Poly Glenoids are available in conventional polyethylene and in highly crosslinked polyethylene with Vitamin E (E-Dur).
The LINK Embrace Shoulder System is supported by a streamlined, lightweight and ergonomic instrument set.

Dear Terry Powell:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

| Indications for Use: | General indications: The LINK Embrace Shoulder System - Anatomic Configuration is intended for anatomic total or hemi shoulder arthroplasty. |
| Indications: |
- A severely painful and/or disabled shoulder joint resulting from osteoarthritis, traumatic arthritis or rheumatoid arthritis
- Avascular necrosis of the humeral head
- Deformity and/or limited motion
- Fracture-dislocations of the proximal humerus where the articular surface is severely comminuted, separated from its blood supply or where the surgeon's experience indicates that alternative methods of treatment are unsatisfactory
- Revision of a failed primary component
- Ununited humeral head fractures
- Cuff tear arthropathy (CTA Heads only)
The All Poly Glenoid Components are intended for cemented use.
The Humeral Stems, Standard with CaP (HX) and Short with CaP (HX), are intended for cementless fixation. |
| | The Humeral Stems, Standard without CaP (HX) and Short without CaP (HX), are intended for cemented or cementless fixation.
The Humeral Fracture Stems are intended for cemented or cementless fixation. |
| | Comparison to the predicate: The subject system is substantially equivalent to the predicates in that all are hemi or total shoulder systems intended for an anatomic configuration, all describe use for primary, revision (i.e., previously |
4
5
failed joint replacement), or fracture indications, and all describe use for cuff tear arthroplasty.
The subject system is manufactured from Ti6Al4V alloy with some components also having a CaP coating, CoCrMo alloy, and UHMWPE, like the predicates.
The subject and predicate systems include a range of humeral stems for cemented or cementless fixation within the humerus, which are assembled to Humeral Heads (with corresponding Head Adapters) that articulate with Cemented All Poly Glenoids.
There are also minor differences between the subject and predicate systems. The subject and predicate Biomet systems include monolithic stems that mate with head adaptors and heads, while the predicate SMR system has modular stems that mate with humeral bodies, head adaptors and humeral heads. The subject CTA heads mate directly with the humeral stems, where the predicate LIMA CTA heads are used with an adapter. The subject All Poly Glenoids have 4 pegs and are available in conventional polyethylene and in highly crosslinked polyethylene with Vitamin E (E-Dur), whereas the predicate LIMA All Poly Glenoids have 3 pegs (or a single peg design) and are available in conventional polyethylene. The subject system offers head adaptors in several offsets and a neutral version with or without suture holes. The head adaptors are assembled to the humeral stems with a taper connection and assembly screw. The use of a supplemental assembly screw and the option for suture holes differs from the adapters of the predicate systems. All systems offer various component sizes to accommodate differences in patient anatomies, although the specific dimensions of each system's components are unique. All systems feature mechanical taper connections for assembly of the humeral constructs, although the specific dimensions of each system's tapers differ. Engineering analyses and mechanical tests were conducted to demonstrate equivalent performance despite minor design differences.
Performance Testing: Non-clinical performance testing and analysis were provided, including:
- Range of Motion analysis (ASTM F1378) -
- -Glenoid loosening (ASTM F2028)
- -Fatigue testing with Fretting/Corrosion assessment
- Static and post-fatigue evaluation of component Locking -Mechanisms (ASTM F2009)
- Wear Rationale -
- Characterization of UHMWPE sterilized EO (reference -K200368)
- Biocompatibility evaluation -
