Fusion rates and adverse event rates
Indications for Use
The CONDUIT™ Cervical Cages with a microscopic roughened surface and micro and nano-scale features are intervertebral body fusion devices intended for use for anterior cervical in skeletally mature patients with cervical disc degeneration and/or cervical spinal instability, as confirmed by imaging studies (radiculopathy, myelopathy, myelopathy, and/or pain at multiple contiguous levels from C2 - Tl. The CONDUIT™ Cervical Cages are also to be used with supplemental fixation systems that have been cleared for use in the cervical spine. CONDUIT™ Cervical Cages are designed for use with autogenous and/or allogeneic bone graft comprised of cancellous, and/or cortiocancellous bone graft, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion.
Device Story
CONDUIT™ Cages are 3D-printed porous titanium interbody fusion devices; used to stabilize spinal segments and restore height in cervical (C2-T1) and lumbar (L2-S1) spine. Devices feature microscopic roughened surfaces with micro/nano-scale features. Used with autogenous/allogeneic bone graft or FDA-cleared bone void fillers (e.g., FIBERGRAFT™ BG Putty). Operated by surgeons in clinical settings; requires supplemental fixation (e.g., pedicle screws, plates). Input: patient anatomy/pathology; Output: structural support for fusion. Benefits: facilitates spinal fusion in degenerative disc disease patients. FIBERGRAFT™ BG Putty is an osteoconductive, resorbable bone void filler packed into defects; not for load-bearing; requires rigid stabilization.

#### F. Device Description
The CONDUIT™ Technology platform is a comprehensive portfolio of 3D-printed porous titanium interbody devices intended to stabilize the spinal segment, restore intervertebral height and to facilitate interbody fusion in the cervical (C2-T1) and lumbar spine (L2-S1). Designed to treat cervical and lumbar degenerative disc disease, the platform consists of the Cervical, Transforaminal (TLIF), Lateral (LLIF), Anterior (ALIF) and Transforaminal/Posterior Lumbar (T/PLIF) systems. Each system features a full breadth of sizes, footprints, heights and angles. The devices are intended to be used with supplemental spinal fixation, either applied anterior or posterior (e.g. using posterior pedicle screws, anterior plate system or anterior screw and rod system).
The CONDUIT™ Cages are made from Ti-6A1-4V ELI conforming to ASTM F3001 with an additive manufacturing process (Selective Laser Melting). The design contains solid structures and porous structures. The hollow geometry of the implants allows them to be packed with autogenous, or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft, or a bone void filler as cleared by FDA for use in intervertebral body fusion.
The 3D Printed CONDUIT™ Cages have a microscopic roughened surface with micro and nanoscale features. The micro and nano features are on all surfaces of the cage, including the superior, inferior, and peripheral surfaces, as well as each member of the internal cell structure.
The FIBERGRAFT™ BG Putty is an osteoconductive, resorbable, biocompatible bone graft substitute to be gently packed into defect sites and to be used as non-structural scaffolds. The FIBERGRAFT™ BG putty is made from 45S5 bioactive glass, where the bioactive glass components are mixed with an absorbable/polymeric carrier to form a cohesive material.
{12}------------------------------------------------
The purpose of this submission is to expand the indications for the of CONDUIT™ Cages to include its use with FIBERGRAFT™ BG Putty. Additionally, the indications for the ALIF, TLIF, and T/PLIF cages are being expanded to include the use of allogeneic bone graft comprised of cancellous, and/or corticocancellous bonegraft.

These spinal implants are to be used with autogenous bone graft and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone graft, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion. CONDUIT™ LLIF Cage is to be used with supplemental fixation. Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral cage.
# CONDUIT™ T/PLIF Cage
The CONDUIT™ T/PLIF Cages with a microscopic roughened surface and micro and nanoscale features in combination with supplemental fixation are indicated for use with autogenous and/or allogeneic bone graft comprised of cancellous, and/or corticocancellous bone graft, or a bone void filler as cleared by FDA for use in intervertebral body fusion to facilitate fusion in patients with degenerative disc disease (DDD) at one or two contiguous spinal levels from L2 - S1 whose condition requires the use of interbody fusion. Degenerative disc disease is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. These patients may have had a previous non-fusion spinal surgery at the involved spinal level(s). Patients must be skeletally mature. Patients should have received 6 months of nonoperative treatment prior to treatment with the devices.
# FIBERGRAFT™ BG Putty
FIBERGRAFT™ BG Putty - Bone Graft Substitute is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. FIBERGRAFT BG Putty is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space, extremities and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process. FIBERGRAFT BG Putty must be used with autograft in the posterolateral spine. When used in intervertebral body fusion procedures, FIBERGRAFT BG Putty must be used on its own with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
FIBERGRAFT BG Putty is not indicated for use in load-bearing applications; therefore, standard

### H. Summary of Similarities and Differences in Technological Characteristics, Performance, and Intended Use
The purpose of this Traditional 510(k) is to expand the indications for of the CONDUIT™ Cages to include its used with FIBERGRAFT™ BG Putty. Additionally, the indications for the ALIF, TLIF, and T/PLIF cages are being expanded to include the use of allogeneic bone graft comprised of cancellous, and/or corticocancellous bone graft. The subject device is substantially equivalent to the predicate devices with respect to indications, design, function, and performance. There are no differences in technological characteristics that will raise new concerns of safety or performance.
#### I. Materials
The CONDUIT™ Cervical and Lumbar Cages are all constructed from Standard Specification for Additive Manufacturing Titanium-6 Vanadium ELI with Extra Low Interstitials components using full-melt powder bed fusion in conformance with ASTM F3001. The BG Putty is composed of the same bioactive glass material with the same bioactive glass chemical composition and the same type and duration of patient contact as the predicate. The materials and manufacturing process for the CONDUIT™ subject devices are identical to that of the predicate device. Similarly, the materials and composition of the BG Putty device are identical to that of the predicate device and the manufacturing process remains substantially the same as that of the predicate. It is important to note that the manufacturing location of BG Putty was moved from Steris to Prosidyan (now DePuy Synthes), however the process has not changed.
#### J. Performance Data
The performance of the CONDUIT™ Cervical and Lumbar Cages and the FIBERGRAFTTM BG Putty have been assessed individually within their respective submissions (K201605, and K170306). Clinical data has been utilized to demonstrate the performance and safety of the expanded indications for use, which includes the use of the CONDUIT™ Cages with FIBERGRAFT™ BGPutty. The clinical data includes radiographic and clinical outcomes from a retrospective study and two investigator-initiated studies. The data provided includes 178 subjects and was collected from multiple sites across the United States (CA, TX, FL) to capture a variety of populations with diverse gender and racial/ethnic backgrounds that is representative of the intended users of the subject devices. The results of the data support the performance of the subject devices in intervertebral body fusion based on fusion and adverse event rates. Additional rationales were provided to justify the expanded indications based upon the clinical data results.
#### K. Conclusion
Based on the body of data presented throughout the submission, it has been determined that the subject devices are substantially equivalent to the predicate devices with respect to indications for use, technological characteristics, and performance data.
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.
