Regulatory Classification
Identification
A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

## Device Description:
The Verteloc Spinal System is a modular vertebral body replacement (VBR) system intended to replace a diseased, collapsed, damaged or unstable cervical vertebral body following partial or total corpectomy. The VerteLoc device comprise of three components; two end bodies and one mid body, which when used in combination is used to replace a measured deficit in the patient's spine. The VerteLoc device is offered in a variety of footprints and heights to accommodate the needs of patients.
{4}------------------------------------------------
When assembled, the central portion of the end and mid bodies create an inner hollow for the placement of autograft and/or autograft bone graft material. The VerteLoc device is manufactured from unreinforced PEEK OPTIMA LT1 as per ASTM F2026 with titanium pins as per ASTM F136 and ISO 5832-3 as well as tantalum marker beads as per ASTM F560 and ISO 13782.
The VerteLoc Spinal System VBR is to be used in conjunction with supplemental fixation systems.
## Indications for Use:
The VerteLoc Spinal System is indicated for use as a cervical vertebral body replacement (VBR) fusion device in the cervical spine (C3-C7) in skeletally mature patients for partial or total replacement of diseased, collapsed, damaged or unstable vertebral body due to tumour, trauma (i.e., fracture), or for reconstruction following corpectomy performed to achieve decompression of the spinal cord and neural tissues.
The VerteLoc Spinal System is to be used with bone graft material. The VerteLoc Spinal System is intended for use with supplemental internal fixation that has been cleared by the FDA.
## Summary of Technological Characteristics:
The VerteLoc Spinal System share the following technological characteristics as the predicate devices:
- . The VerteLoc Spinal System has the same intended use as the DePuy Synthes Bengal Stackable Cage System.
- . The VerteLoc Spinal System has a shared indications for use as the DePuv Synthes Bengal Stackable Cage System.
- The VerteLoc Spinal System Cages are manufactured from the same material as the DePuy Synthes Bengal Stackable Cage System as well as Signature Orthopaedics Arlington Cages with the exception of the titanium pins.
- . The VerteLoc Spinal System Cages have the same height range as the DePuy Synthes Bengal Stackable Cage System and has the available length and widths fall within the Depuy Synthes Bengal Stackable Cage System' range.
- o The Verteloc Spinal System Cages are packaged, transported and sterilised through the same method(s) as Signature Orthopaedics Arlington Cages.
The following are the technological differences between the VerteLoc Spinal System and the predicate devices:
- . The VerteLoc Spinal Cage utilises titanium pins to assist in initial fixation where the Depuy Synthes Bengal Stackable Cage System does not include additional titanium pins and utilises the surface finish on the outer cages top and bottom surface areas (the same as the subject device) only.
- . The VerteLoc Spinal Cage utilises a snap-fit lock between stackable cages where as the DePuy Synthes Bengal Stackable Cage System uses screw and nut fasteners.
## Performance Data:
Non-clinical testing and engineering evaluations were conducted to verify that the performance of the Verteloc Spinal System is adequate for anticipated in-vivo use. No animal or clinical testing was required to support substantial equivalence. Nonclinical testing carried out included:
{5}------------------------------------------------
- . Static Axial Compression Testing
- Static Torsional Testing
- Dynamic Axial Compression Testing
- Dynamic Torsional Testing
- . Subsidence Testing
The results of verification and validation analyses demonstrated the Verteloc Spinal System to be substantially equivalent to the predicate devices.
## Conclusion:
The subject devices are substantially equivalent to the predicate devices since it has the same intended use, indications for use, materials, design features, and sterilisation to either all or one of the predicate devices. Non-clinical testing support the substantial equivalence claim.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
