No
The description focuses on the material, design, and mechanical properties of the wedge and screws, with no mention of AI or ML for analysis, planning, or any other function.
No
The device is described as a system for internal bone fixation for bone fractures or osteotomies, which is a structural support device rather than a therapeutic one that treats or cures a disease.
No
The device is described as a system for internal bone fixation (wedges and screws) and is not intended for diagnosis, but rather for surgical correction of bone fractures or osteotomies.
No
The device description clearly states it is a "family of additively manufactured titanium wedges" and associated screws, which are physical hardware components used for bone fixation.
No, 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 Function: The Trigon™ Ti Stand-Alone Wedge Fixation System is a surgical implant used for internal bone fixation during foot surgery. It is a physical device inserted into the body to provide structural support and stability to fractured or osteotomized bones.
- Intended Use: The intended use clearly states it's for "internal bone fixation for bone fractures or osteotomies in the foot." This is a surgical procedure, not a diagnostic test performed on a sample outside the body.
The information provided describes a medical device used in surgery, not a diagnostic test.

Device Description
The Trigon Ti Stand-Alone Wedge Fixation System is a family of additively manufactured titanium wedges used for angular correction of small bones of the foot. The wedges incorporate an organized lattice structure and two screw-receiving holes. The system rectangular and kidney shaped wedges may or may not include a window for containing grafting material. The wedges are designed in rectangular and kidney shaped footprints in a range of sizes (16x16mm to 20x22mm) and in multiple thicknesses (5 to 12mm). The associated 2.5mm diameter screws are designed in lengths of 10 to 20mm.
When used with the provided screw fixation the Trigon wedges may be used with or without ancillary plating. When used without the provided screws Trigon wedges are intended for use with ancillary fixation. Windowless wedge designs that do not allow for graft placement should only be used with ancillary plating.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.
(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

PREDICATE DEVICE IDENTIFICATION
The Trigon Ti Stand-Alone Wedge Fixation System is substantially equivalent to the following predicates:
| 510(k) Number | Predicate Device Name / Manufacturer | Primary
Predicate |
|---------------|----------------------------------------------|----------------------|
| K151256 | Arthrex BioSync Wedge System | ✓ |
| K161037 | Life Spine Tarsa-Link Wedge Fixation System | |
| K140531 | Wright Medical Technology BIOFOAM Bone Wedge | |
The following reference devices are also cited in this submission:
- Nvision Biomedical's Healix™ Compression Screw System (K182949) ●
- HT Medical's Neofuse™ Ti3D PLIF/TLIF/Cervical Interbody (K170318)
SUMMARY OF NON-CLINICAL TESTING
No FDA performance standards have been established for the Trigon Ti Stand-Alone Wedge Fixation System. The following testing was performed:
- Compression and compression shear (per ASTM F2077)
- Expulsion
- Engineering analysis to evaluate screw mechanical strength and pullout strength .
The results of these tests indicate that the Trigon Ti Stand-Alone Wedge Fixation System is substantially equivalent to the predicate devices.
EQUIVALENCE TO PREDICATE DEVICES
Nvision believes that the Trigon Ti Stand-Alone Wedge Fixation System is substantially equivalent to the predicate devices. The subject wedges are similar to the predicates in that the footprint sizes and thicknesses are similar, they are intended for use with ancillary fixation, and

To the right of the "N" is the word "VISION" in a bold, sans-serif font. Below the logo is the phrase "biomedical technologies" in a smaller, italicized font.
they incorporate the same number of ancillary screws. Furthermore, the ancillary screws are similar in size. Unlike the predicates, the Trigon wedges are additively manufactured from titanium and contain an organized lattice structure, however testing demonstrated that this does not negatively impact equivalence.
CONCLUSION
Based on the testing performed, including compression shear, expulsion, and engineering analysis, it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate devices. The similar indications for use, technological characteristics, and performance characteristics for the proposed Trigon Ti Stand-Alone Wedge Fixation System are assessed to be substantially equivalent to the predicate devices.
