# Device Description
The Idvs® ALIF 3DTi consists of interbody fusion devices intended for stabilization use and to promote bone fusion during the normal healing process following surgical correction of disorders of the lumbar spine.
The Idys® ALIF 3DTi cages, which have various widths and heights, are designed for use as lumbar intervertebral body fusion devices. The device has a shape which restores the intervertebral height and lordosis. The device contains two slots to receive the autograft bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone to help promote fusion process between the endplates.
The device has to be used with autograft bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone graft.
The Idys® ALIF 3DTi cage is manufactured from medical grade Ti-6Al-4V ELI Titanium alloy compliant with ASTM F3001 and ASTM F136 and is used with bone graft. The insert for fixation of the plate is made of ASTM F2026 compliant polyetheretherketone (PEEK). The screws and
{4}------------------------------------------------
plates are made from Ti-6Al-4V ELI per ASTM F136 and are anodized in different colors, according to their length. Idvs® ALIF 3DTi cages are positioned using a set of surgical instruments common for anterior lumbar approach. It is essential to insert implants with instrumentation specifically designed for this purpose. The cages are provided sterile and are for single use only.
# Intended Use/Indications for Use
The Idvs® ALIF 3DTi (Anterior Lumbar Integrated Fusion) System is intended for use in patients with degenerative disc disease (DDD) at one (1) or two (2) contiguous levels of the lumbosacral spine (L2-S1). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. The Idys® ALIF System should be used with the integrated fixation screws provided.
The Idys® ALIF 3DTi cages are intended to be used with autograft bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone to help promote fusion.
# Substantial Equivalence
The Idys® ALIF 3DTi and the predicate Idys® ALIF (K172083) are designed for use as lumbar intervertebral body fusion devices Both devices are available with equivalent range and configurations to accommodate patient anatomy.
The Idys® ALIF 3DTi and the Idys® ALIF (K172083) feature a similar outer shape and design. The design features two slots to allow the incorporation of autograft bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone to help promote fusion. Each of the superior and inferior surfaces of the Idys® ALIF 3DTi and the Idys® ALIF (K172083) have teeth to grip the surface of the vertebral endplates and help to resist expulsion.
The primary difference between the cleared Idys® ALIF (K172083) and the subject device is the change of the raw material and the manufacturing process of the cage. Idvs® ALIF 3DTi caqe are made of ASTM F3001 titanium alloy components and ASTM F136 Ti-6AI-4V ELI, while the predicate cage (K172083) is made of F2026 compliant polyetheretherketone (PEEK). Moreover, the Idys® ALIF 3DTi has a porous structure that integrates to the bone while the predicate Idys® ALIF cages use teeth. Idys® ALIF 3DTi has the same insert of its predicate device, made of F2026 compliant polyetheretherketone (PEEK), in order to attach to the plate.
#### Performance Data
#### Biocompatibility
The modified device has been demonstrated to be biocompatible in accordance with ISO 10993-1 Part 1.
#### Sterility and Cleaning
Repeated sterilization validation per ISO 11737 and ISO 11137 has been successfully completed. Cleaning validation has shown acceptable limits of residues.
#### Mechanical Testing
Bench mechanical testing according to ASTM F2077 and ASTM F2267 were used to support the decision of substantial equivalence with Idys® ALIF cages and Idys® ALIF ZP 3DTi
{5}------------------------------------------------
predicate devices (K172083 and K192168, respectively). Specifically, CLARIANCE performed static and dynamic axial compression testing, static and dynamic compression shear testing, subsidence testing, expulsion testing, static torsion testing, and wear testing (titanium particles), all of which demonstrated the substantial equivalence of the system to legally marketed devices.
Based on the clinical performance as documented in the pivotal clinical study, the Idys® ALIF 3DTi has a safety and effectiveness profile that is similar to the predicate device.
# Conclusions
The Idys® ALIF 3DTi is as safe and effective as the Idys® ALIF (K172083) and Idys® ALIF ZP 3DTi (K192168). The Idys® ALIF 3DTi has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device. The minor technological differences between the Idys® ALIF 3DTi and its predicate devices do not raise any new issues of safety or effectiveness. Performance data demonstrate that the Idys® ALIF 3DTi is as safe and effective as its predicates. Thus, the Idys® ALIF 3DTi is substantially equivalent.

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.
