Indications for Use
The Avenue® L Lateral Lumbar Cage system is indicated for intervertebral body fusion of the lumbar spine, from L2 to S1, in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The device system is designed for use with or without integrated fixation and must be used in conjunction with posterior supplemental fixation (e.g. pedicle screws). The device system is intended to be used with autograft and/or allogenic bone graft composed of cancellous and/or corticocancellous bone graft to facilitate fusion.
Device Story
Intervertebral body fusion cages; PEEK-OPTIMA LT1 construction; titanium alloy or tantalum markers for radiographic visibility; optional integrated titanium alloy anchoring plates (VerteBRIDGE) for fixation. Implanted via lateral, transforaminal, or anterior approaches. Used in conjunction with supplemental posterior fixation and autograft/allograft bone. Designed for lumbar spine fusion (L2-S1) or thoracolumbar vertebral body replacement (ROI-T). Surgeon-operated in clinical/OR setting. Provides structural support to disc space; facilitates fusion; restores spinal stability.
Clinical Evidence
No clinical data; bench testing only. A comprehensive clinical literature review was conducted to assess safety concerns regarding the use of allograft in the lumbar spine, concluding no additional risks were introduced by the modification.
Technological Characteristics
Materials: PEEK-OPTIMA LT1 (ASTM F2026), titanium alloy (ASTM F136), tantalum (ASTM F560). Design: Interbody cages with hollow central cavities, teeth for stability, and optional integrated anchoring plates. Connectivity: None. Sterilization: Not specified. Software: None.
Indications for Use
Indicated for intervertebral body fusion of lumbar spine (L2-S1) in skeletally mature patients with 6 months of failed non-operative treatment for degenerative disc disease (DDD) with up to Grade I spondylolisthesis or retrolisthesis. ROI-T also indicated for partial vertebral body replacement (T1-L5) for tumor or trauma/fracture. Requires supplemental fixation.

### Device Description:
The Avenue L Lateral Lumbar Cage is intended for use as an interbody fusion device in the lumbar spine. The device consists of intervertebral cages manufactured from medical grade PEEK OPTIMA " LT1 (ASTM F2026) with embedded titanium alloy markers (ASTM F136) to facilitate visibility in x-ray imaging. The Avenue L Lateral Lumbar Cage is available with VerteBRIDGE® titanium alloy anchoring plates which facilitate fixation to the superior and inferior vertebra, which may be used in addition to supplemental fixation. The Avenue L Lateral Lumbar Cage is designed for placement using a lateral surgical approach.
The Avenue T TLIF (Transforaminal Lumbar Interbody Fusion) Cage system is comprised of various size interbody cages, integrated fixation anchoring plates (VerteBRIDGE® Plating), and associated instrumentation. The Avenue T TLIF Cage System is intended for use as an intervertebral body fusion cage in the anterior column of the lumbar spine. The Avenue T TLIF Cage System is designed to be implanted obliquely via a transforaminal approach. The cages feature rows of uni-directional teeth on the superior and inferior surfaces to aid stability and a tapered bullet-shaped tip to ease insertion. The Avenue T TLIF Cage System have a hollow central cavity to contain autogenous bone graft for fusion.
After cage placement, the VerteBRIDGE integrated fixation anchoring plates may be inserted into the cage to provide further stability and fixation. The VerteBRIDGE anchoring plates pass through the cage via slots and lodge firmly into the superior and inferior vertebral endplates. The VerteBRIDGE anchoring plates lock into the Avenue T TLIF Cage System via an integral locking pin.
The Avenue T TLIF Cage System is manufactured from PEEK-OPTIMA LT1 with embedded ASTM F136 titanium alloy radiographic markers and anchoring plate locking pins. The VerteBRIDGE anchoring plates are manufactured from ASTM F136 titanium alloy. The Avenue T TLIF Cage System are designed in a variety of length, and lordosis combinations to best fit varying patient anatomies.
The ROI-A ALIF Cage System is intended for use as an interbody fusion device in the lumbar spine. The device is manufactured from medical grade PEEK OPTIMA LT1 in accordance with ASTM F2026 and has tantalum markers conforming to ASTM F560 embedded in the implant to facilitate visibility in x-ray imaging. The subject device is designed for placement using either an anterior or anterolateral approach. The ROI-A ALIF Cage System implants feature two slots which allow for use with device-specific integrated fixation - the ROI-A VerteBRIDGE anchoring plate. The ROI-A ALIF Cage System VerteBRIDGE anchoring plate is made of titanium alloy (Ti-6Al-4V, ASTM F136) and can be inserted to obtain fixation to the vertebral bone and create a standalone lumbar interbody fusion cage construct.
The ROI-T Implant System consists of crescent shaped cages in a variety of heights and lordotic angles. The ROI-T Implant System implant has an enclosed graft space design. The superior and inferior surfaces of the devices have a pattern of teeth to provide increased stability and to prevent movement of the implants. The ROI-T Implant System PEEK cages are designed to be inserted via a transforaminal approach. The ROI-T Implant System cages are manufactured from

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.
