## 3. Legally Marketed Predicate Devices
Perimeter OTIS™ 1.0 Optical Coherence Tomography (OCT) System, K160240
# 4. Device Description
The Perimeter OTIS 1B is based on optical coherence tomography (OCT) imaging which is similar to ultrasound, but uses non-ionizing, low-power optical radiation to produce high resolution, sub-surface images of a tissue sample. Due to the extremely high velocity of light, optical echoes (reflected and backscattered light from the sample) cannot be measured directly using a photodetector. Instead, OCT devices use an interferometer to compare a reference beam of light to the backscattered light returning from the tissue sample. The features in an OCT image are created by changes in the optical properties (namely scattering, absorption, and index of refraction) of the sample.
The Perimeter OTIS 1B collects and displays OCT images of human tissue with comparable image quality to other previously 510(k)-cleared OCT imaging systems and, specifically, the Perimeter OTIS 1.0 System (K160240). Like its predicate, the Perimeter OTIS 1B has automated the OCT scanning of the specimen surface, standardizing the image collection process.
{7}------------------------------------------------
The Perimeter OTIS 1B includes a white light image (e.g., photograph) of the specimen, to assist the clinician in viewing the OCT images with a reference to the white light image and the OCT image scan position. The Perimeter OTIS 1B also includes user interface options, such as the ability to "scroll" through the OCT images, across a specimen's surface, as well as to zoom and pan in more closely to examine areas of interest, as desired.
#### Indications for Use 5.
The OTIS 1B Optical Coherence Tomography System is indicated for use as an imaging tool in the evaluation of excised human tissue microstructure by providing twodimensional, cross-sectional, real-time depth visualization with image review manipulation software for identifying and annotating regions of interest.

#### Technological Characteristics 8.
The Perimeter OTIS 1B is substantially equivalent to the Perimeter OTIS 1.0 [K160240] as the devices are identical and have the same intended use.
Both Perimeter OTIS Systems provide a standardized "stepping" of the OCT image acquisition probe across a pre-set scan area (e.g., 3 cm - 5 cm). The Perimeter OTIS Systems perform this surface image acquisition by using an automated mechanical stage and precise probe positioning.
The Perimeter OTIS 1B and the predicate device, OTIS 1.0, use near infrared (NIR) light to produce Optical Coherence Tomography images. The Perimeter OTIS Systems have a center wavelength of 1325 ± 20 nm. The Perimeter OTIS Systems position the probe automatically during imaging - reducing the operator workload and ensuring consistent
{9}------------------------------------------------
sample coverage. The intended use of the Perimeter OTIS 1B is the same as OTIS 1.0; the indications for use for OTIS 1B are encompassed within the intended use of the OTIS Systems; and the device constructions are identical. Therefore, Perimeter OTIS 1B is as safe and effective as the predicate device.
### 9. Performance and Safety Testing
Perimeter completed verification and validation activities under Perimeter Design Control procedures to ensure that verification studies demonstrated that outputs met input requirements, and that validation studies demonstrated that the Perimeter OTIS fulfilled the intended use and user needs.
Perimeter validated the usability of the OTIS Systems per IEC 62366:2007 - Application of usability engineering to medical devices. Testing was performed with representative users in actual and simulated use environments.
Perimeter validated that the OTIS 1B can obtain OCT images with sufficient image quality to identify excised tissue microstructure features as compared to histopathology, at a level comparable to other OCT imaging systems.
External laser, electrical, and EMC testing successfully demonstrated the safety of the Perimeter OTIS Systems in its intended environment. Perimeter OTIS Systems employ a near infrared super luminescent diode for optical image acquisition, as well as a sufface sensing laser system. Both laser systems are classified as Class 1 laser, per IEC 60825-1:2014, requiring no special optical safety precautions.
### 10. Conclusions
Perimeter Medical Imaging, Inc. has demonstrated that the OTIS 1B Optical Coherence Tomography System has the same intended use and is substantially equivalent to its predicate devices, the OTIS™ 1.0 Optical Coherence Tomography System. The Perimeter OTIS 1B, as it is identical in construction to the OTIS 1.0, complies with recognized standards and guidelines for electrical safety, and biocompatibility. Testing has demonstrated that the devices is as safe and effective as the predicate device.

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.
