Provides high-quality imaging for brain, vascular, and soft tissue structures. Benefits include improved diagnostic targeting and anatomical coverage compared to standard coils. Device does not generate power; it is stimulated by the MRI system's transmit body coil.
Clinical Evidence
No clinical trials performed. Substantial equivalence supported by bench testing and comparative imaging analysis. Bench testing included SNR analysis, sensitivity profiling, hazard analysis, FMEA, blocking analysis, and heat testing. Comparative imaging in sagittal, coronal, and transverse planes demonstrated that the subject device provides diagnostic quality images of the brain, neck, and upper chest regions equivalent to the predicate.
Technological Characteristics

## Description of the Device
The 8 individual coils that comprise the ST SENSE NV 8 Array Coil (Neurovascular Array) interface with a 1.0 Tesla, 8-channel Panorama MRI scanner. Between the device and its predicate, there are slight variations in physical size of electrical and physical aspects (to accommodate focus of anatomies) The designs and materials used to manufacture the individual coils are nearly identical and are no different from standard MRI coil technology that has existed for years. The geometry of each coil housing has been formed by utilizing a rigid housing that disconnects to facilitate both close coupling of the imaging coil's regionof-sensitivity to the anatomy of interest on a patient anatomy, and ease of entry to each patient. All employ similar blocking, impedance matching and integrated pre-amplifier circuitry.

## Indications for Use
The intended use for this 1.0T 8-channel Neurovascular Coil is to facilitate diagnostic targeting imaging of brain, neck and upper chest that may be interpreted by a trained physician.
- To collect image data throughout the region of the head, neck and chest region of the . patient using a Philips vertical-field 1.0T MR scanner.
- Various regions of the Brain, including brainstem, pituitary, IAC, and orbits, intra 0 cerebral vascular structure, soft tissue of the facial area, arteries between the aortic arch and the Circle of Willis, soft tissue in the anterior neck, pediatric head/neck, cervical spine, long top and brachial plexus, and with the ability to scan feet and ankles.
## Technological Characteristics
The comparison between the predicate and the current submission is described, below.
- 1. Design. This submission is for a Receive-Only Coil for an MRI System. It is a dedicated coil that may give diagnostic quality images of the tops of the lungs all the way to the brain, with angiography of the entire anatomy within this range. It is an 8-channel receive coil with all channels designed to work at once, in conjunction with the system Body Coil. The predicate covers very similar anatomy, yet for a different system and field strength.
- 2. Material. It is largely polycarbonate, painted, and with Ultem latching pieces. The distinction between the predicate and current submission is non-substantive in that they both have insulating qualities proven by dielectric withstand testing, and have passed liquid ingress testing.
- 3. Chemical Composition. Both products, the predicate and current submission, have biocompatible construction, using polycarbonate with enamel paint, as demonstrated by cytotoxicity testing and by their history of use in previously cleared devices.
- 4. Energy Source. Both of these products are receive-only coils not generating their own power, but rather stimulated by the MRI system as the energy source.
## Non-Clinical Tests
The coils have similar dimension in the head area and have induced similar fields by the transmit coil (Body Coil) that stimulates them. The predicate and current submission were compared by similar risk management efforts, as listed below, and determined to be substantially equivalent.
- Sensitivity profile .
- SNR Analysis .

# Clinical Tests
Analyses in all 3 planes (sagittal, coronal and transverse) were run to show that the anatomies of the submitted and predicate coils have substantial equivalence; the predicate device images the complete brain and neck regions, and the current Neurovascular submission images anatomies between brain and lung tops.
## Final Discussion
As described in the Design section, above, the submission is also for eight loops dedicated over a similar region of interest as its predicate, with the coils offering no energy source, and exhibiting strong decoupling; thus, the study determines that the submitted device is as safe, as effective, and performs as well or better than the legally-marketed device on the target anatomies, in its respective field strength.

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.
