The LaborPro System is intended for monitoring the active phase of labor in women with term gestations and a singleton fetus in vertex presentation. The device intermittently assesses fetal head station, position and cervical dilation. Cervical dilation using LaborPro is assessed using position sensors during vaginal examination. The LaborPro also may be used to measure cervical length, pubic arch angle and interspinous diameter using position sensors during vaginal examination. The LaborPro combines a magnetic tracking system including a transmitter and position sensor with an ultrasound imaging system (not included with the LaborPro). Measurements are displayed numerically and graphically as a function of time to show the progress of labor.
Device Story
LaborPro System is a minimally invasive, magnetic-based tracking device used during routine vaginal examinations by physicians to monitor labor progress. It consists of a console, touch screen, magnetic transmitter, and position sensors. The system tracks the spatial location of the sensor tip, which is used to touch external landmarks or mark structures on an integrated (but not supplied) ultrasound image. By calculating relative distances and angles between these points, the system quantifies cervical dilation, fetal head station, cervical length, pubic arch angle, and interspinous diameter. Data is displayed numerically and graphically over time. The device assists clinicians in assessing labor progression, potentially aiding clinical decision-making during the active phase of labor.
Clinical Evidence
Clinical study conducted to validate accuracy against two independent experienced attending physicians/caregivers (gold-standard). Bench testing performed on a phantom. Electrical safety and electromagnetic compatibility testing performed per IEC 60601-1 and IEC 60601-1-2. Software verification and validation conducted per SRS.

#### 5.12 Intended Use / Indication for Use:
The LaborPro System is intended for monitoring the active phase of labor in women with term gestations and a singleton fetus in vertex presentation. The device intermittently assesses fetal head station, position and cervical dilation. Cervical dilation using LaborPro is assessed using position sensors during vaginal examination. The LaborPro also may be used to measure cervical length, pubic arch angle and interspinous diameter using position

sensors during vaginal examination. The LaborPro combines a magnetic tracking system including a transmitter and position sensor with an ultrasound imaging system (not included with the LaborPro). Measurements are displayed numerically and graphically as a function of time to show the progress of labor.
#### 5.13 Device Description:
The LaborPro System is comprised of the following components:
- 1. A magnetic based tracking system
- 2. A system console which integrates the tracker unit electronics and the system computer,
- 3. A touch screen monitor, used for display and operation.
- 4. LaborPro software application
- 5. Sensor Sleeve and reference sticker (an "off the shelf" tape and bandage adhesive).
- 6. An 'off the shelf' ultrasound device; not supplied with the system
- 7. An 'off the shelf CardioTocoGram (CTG) monitor (optional); not supplied with the system
LaborPro System, a minimally invasive device, assesses labor The parameters intermittently by accompanying the physician during his/her routine examinations.
The LaborPro magnetic position tracking system is designed for tracking the spatial location of the sensor tip. Spatial localization of landmarks may be simply obtained by either touching external landmarks of interest with the sensor tip and/or by marking structures of interest on a ultrasound image extracted from an "off the shelf" calibrated ultrasound probe aligned with a position sensor. The spatial localization of each sensor then may allow for the assessment of certain measurements such as cervical dilatation simply by touching points within the system's working area and yielding the relative distance/angles between the touched points in a caliper-like fashion. In addition, localization of key anatomical points either by touching external landmarks with a sensor tip or marking structures of interest on an ultrasound image enable mapping of the spatial position and orientation of the pelvis and specifically the level of the pelvic inlet plane; which is used as the relative plane for the fetal head station measurement.
#### 5.14 Substantial Equivalence:
#### Intended Use
With regard to its intended use, the LaborPro System is substantially equivalent to the combination of its predicate devices. In similarity to the CLM predicate device, the LaborPro enables measurements of labor
{2}------------------------------------------------
progression parameters and is intended for monitoring labor. In addition, the LaborPro system is intended to measure pubic arch angle, interspinous diameter, and cervical length similar to pelvimeters and the Cervilenz Measuring Sound predicate devices respectively.
## Technological Characteristics and Mode of Operation
Similarly to the UltraGuide predicate device, the LaborPro System is based on an integrated "off the shelf" ultrasound and magnetic tracking system. Both devices calculate the relative spatial positions of sensors prior to analysis. Localization and relative distances and angles of landmarks of interest by the LaborPro magnetic based transmitter and sensors/receivers is similar to the CLM predicate that determines the localization and relative distances of landmarks (fetal head and cervical margins) by ultrasound based transmitters and receivers.
## Performance Testing
A set of software, bench and clinical testing was performed in order to demonstrate the performance and accuracy of the LaborPro System and to verify that it does not raise any new safety and effectiveness issues in comparison to its predicate devices. The testing included the following:
- Electrical safety and electromagnetic compatibility testing . according to IEC 60601-1 (and amendments), and IEC 60601-1-2 (and amendment) standards.
- Software verification and validation testing was conducted to . evaluate the performance of the LaborPro System and to verify that it performs according to its specifications described in the Software Requirements Specifications (SRS).
- Bench testing on a phantom. ■
- A clinical study was conducted to validate the accuracy of the 트 LaborPro System against two independent experienced attending physicians and/or caregivers (gold-standard). The study results establish the accuracy of the LaborPro System in measuring labor parameters.
## Summary
The LaborPro System has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate Based on the performance testing results, including software devices. verification and validation process, bench and clinical testing, the analysis of the similarities and differences, Trig Medical Ltd believes that the LaborPro System is substantially equivalent to its predicates without raising new issues of safety or effectiveness.

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.
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.
