Indications for Use
The UBM Plus is designed for imaging the internal structure of the eye including opaque media and anterior segment pathology, for the purpose of diagnosing pathological or traumatic conditions in the eye.
Device Story
UBM Plus is a high-frequency ultrasound B-Scan system for imaging the anterior segment of the eye. It uses a non-contact probe with a Scleral immersion shell to generate and receive pulsed echo ultrasound. The system processes returning echoes to provide a graphic display of ocular structures. Operated by clinicians in a clinical setting, the device provides tools for pan, zoom, annotation, A-Vector, and distance/area/angle measurements. Output is displayed on a screen for the clinician to visualize internal structures, aiding in the diagnosis of pathological or traumatic eye conditions. The device benefits patients by enabling non-invasive visualization of ocular anatomy, particularly when media is opaque.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and acoustic output measurements (IEC 60601-2-37, NEMA UD2, NEMA UD3). Accuracy testing using Gammex Lesion and proprietary phantoms showed <1% error for line, area, and angle measurements.
Technological Characteristics
High-frequency (48 MHz) ultrasound B-Scan system. Features an open-tip probe design requiring a Scleral immersion shell. Provides 256 grey scale levels. Connectivity includes standard display output. Complies with IEC 60601-1, IEC 60601-1-1, IEC 60601-1-2, IEC 60601-2-37, NEMA UD2, and NEMA UD3 standards.
Indications for Use
Indicated for ophthalmic imaging of internal eye structures, including opaque media and anterior segment pathology, to diagnose pathological or traumatic eye conditions. No specific age or gender restrictions noted.
Regulatory Classification
Identification
An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Indications for Use:
Comparison of Technological Characteristics:
The instrument is used for the imaging of the internal structure of the eye including opaque media and anterior segment pathology for the purpose of diagnosing pathological or traumatic conditions of the eye.
The UBM Plus and B-Scan Plus are similar devices in that they are both ultrasonic B-Scans used to image the eye. The UBM Plus has an open tip design with an ultrasonic crystal that resonates at a frequency of 48 MHz, while the B-Scan Plus uses a closed tip design with a single crystal resonating at frequencies of 12 MHZ and 15 MHz. The open tip design of the UBM Plus requires the use of a Scleral Immersion Shell to capture measurements, while the closed tip design of the B-Scan Plus allows for direct contact between the probe and patient without potential injury. The UBM Plus range is fixed at 30mm, while the B-Scan Plus ranges are adjustable with ranges of 30, 50, 60 and 100mm. The UBM Plus runs using an updated software version of the B-Scan Plus. The UBM Plus offers the user the functionality of pan, zoom, annotation, A-Vector, distance/area/angle measurements, 256 grey scale levels, image annotation and gain controls. All of the listed functions are available on the B-Scan Plus, except angle measurements.
The UBM Plus and OTI-Scan 3000 are similar in that they both ultrasonic B-Scans utilizing high frequency probes. The UBM Plus utilizes a frequency of 48 MHz, while the OTI-Scan 3000 utilizes multiple probes with frequencies of 35 MHz and 50 MHz. Both the UBM Plus OTI-Scan 3000 use an open tip design and therefore both require the use of an Immersion Scleral Shell to capture measurements. This is referred to as an immersion cup in the OTI User Manual. The UBM Plus offers the user the functionality of pan, zoom, annotation, A-Vector, distance/area/angle measurements, 256 grey scale levels,

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.
