Indications for Use
The Sunrise device is a non-invasive home care aid in the evaluation of obstructive sleep apnea (OSA) in patients 18 years and older with suspicions of sleep breathing disorders.
Device Story
Sunrise is a cloud-based diagnostic aid for obstructive sleep apnea (OSA) evaluation in home settings. The system utilizes a wearable sensor (Sunrise sensor 2) placed on the patient's chin using adhesive. The sensor captures mandibular movement (via accelerometer/gyroscope), SpO2 and pulse rate (via PPG), and airflow (via thermistor). Data is recorded on-board and processed by proprietary cloud-based software. The software analyzes these inputs to detect respiratory events, identify sleep stages, and determine body position. It generates sleep parameters, including AHI (Apnea-Hypopnea Index), ORDI (Oxygen-Respiration Disturbance Index), and sleep architecture metrics. Results are compiled into a report for review by a healthcare provider to assist in clinical decision-making regarding sleep disorder diagnosis. The device benefits patients by providing a non-invasive, home-based alternative to traditional polysomnography (PSG).
Clinical Evidence
Four clinical studies were conducted. Three retrospective studies (n=289, n=31, n=10) compared device-derived sleep parameters (TST, AHI, ORDI) and position accuracy against PSG. Results showed high agreement; sensitivity for OSA severity (AHI>=5, 15, 30) ranged 0.81-1.00 and specificity 0.75-1.00. A fourth study validated SpO2 and pulse rate accuracy per ISO 80601-2-61:2019 (SpO2 rms 2.70% for 70-100% range; pulse rate rms 1.95 bpm for 51-104 bpm range). Thermistor airflow capture was validated as equivalent to PSG oronasal thermal sensors.
Technological Characteristics
Wearable chin-mounted sensor; materials include housing, PPG window, and adhesives (ISO 10993-1 compliant). Sensors: accelerometer, gyroscope, PPG, thermistor. Power: non-rechargeable lithium coin battery. Connectivity: on-board memory for data storage, cloud-based analysis. Software: moderate level of concern, proprietary algorithm for respiratory event detection and sleep staging. Electrical safety: IEC 60601-1, IEC 60601-1-2 (EMC), IEC 60601-1-11 (home healthcare).
Indications for Use
Indicated for patients 18 years and older with suspected sleep breathing disorders to aid in the evaluation of obstructive sleep apnea (OSA).

{9}------------------------------------------------
### Electrical Safety and Electromagnetic Compatibility (EMC)
Electrical safety and EMC testing were conducted on the device to demonstrate compliance with IEC 60601-1 standard for safety, IEC 60601-1-2 standard for EMC and IEC 60601-1-11 standard for home healthcare environment.
#### Bench Testing
Bench testing was conducted to demonstrate technical equivalency between the subject device and the predicate device. The measured signals of the accelerometer and of the gyroscope between the two sensors were compared and performance found to be equivalent.
#### Clinical Studies
The primary objective of the first three clinical studies was to compare the agreement of sleep parameters between the device and the gold-standard PSG. The algorithm was used to analyze sensor data and evaluate the performance of the device compared to PSG. The performance of the device for sleep parameters was evaluated by Bland-Altman analysis and percentiles-based limits of agreement (LOA) against pre-determined thresholds of clinical acceptability. The performance of the device for OSA severity output was evaluated as standard diagnostic metrics compared to the PSG at three different AHI cut-offs.
The first clinical study was a retrospective, comparative and open study performed in Belgium in 289 patients. Median measurement bias and LOA were -4.50 min (-41.74 to +35.67), -0.46 event/h (-13.52 to +9.00) and +0.15 event/h (-10.70 to +10.12) for TST, AHI and ORDI. respectively. Performance for OSA severity was as following: sensitivity of 0.99, 0.92, 0.81 and specificity of 0.86, 0.94 and 0.99 for AHI>=5, AHI>=15 and AHI>=30, respectively.
The second clinical study was a retrospective, comparative and open study performed in France in 31 patients. Median measurement bias and LOA were -10.50 min (-37.42 to +25.79), +0.20 event/h (-12.30 to +6.30) and +1.01 event/h (-11.24 to +6.21) for TST, AHI and ORDI, respectively. Performance for OSA severity was as following: sensitivity of 1.00, 0.94, 0.87 and specificity of 0.75, 1.00 and 1.00 for AHI>=5, AHI>=15 and AHI>=30. respectively.
The third clinical study was a retrospective, comparative and open study performed in Belgium in 10 patients. The performance of the device for position discrete states was evaluated as global accuracy compared to the PSG: 93%.
For the fourth clinical study, SpO2 and pulse rate accuracies for the Sunrise sensor 2 were validated in accordance with ISO 80601-2-61:2019 201.12.1.101.2 and Annex EE.2 as recommended by the FDA guidance document Pulse Oximeters - Premarket Notification Submissions [510(k)s]. The SpO2 accuracy (rms value) was found to be 2.70% over the range of 70-100%. The pulse rate accuracy (rms value) was found to be 1.95 beats per minute (bpm) for a claimed measurement range of 51 to 104 bpm.
In addition, a validation study was conducted to demonstrate the ability of the Sunrise
{10}------------------------------------------------
sensor 2 thermistor to capture airflow. The signal measured by the Sunrise sensor 2 thermistor was compared to that of an oronasal thermal airflow sensor used in PSG and the performance was found to be equivalent for capturing breathing patterns.
# 8. CONCLUSION
Based on the performance data, the Sunrise device is as safe and as effective as the predicate device and performs equivalently. Therefore, the Sunrise device is substantially equivalent to the predicate device.

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).

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
