Indications for Use
The Integrated CardioRespiratory (ICR) System, when used with ICR Acoustic Sensors and ECG Sensor Electrodes on the chest wall, is intended for use in acquiring and analyzing heart sound data and computing and reporting an estimate of left ventricle Ejection Fraction that is comparable to that derived by 2-D echocardiography. The device is not intended for continuous monitoring of Ejection Fraction. The ICR System is not intended as a sole means of diagnosis. It does not supersede the judgment of the qualified medical personnel. The ICR System is intended to aid the physician in the evaluation of heart function. The interpretation of EF values offered by the ICR System are only significant when used in conjunction with physician over-read as well as consideration of all relevant patient data. Indicated for use in adults only. The ICR System is intended for use under the direct supervision of a licensed healthcare practitioner or personnel trained in its proper use within a hospital or facility providing healthcare.
Device Story
The ICR System is a non-invasive, point-of-care device used in healthcare facilities by trained personnel. It utilizes four acoustic sensors and ECG electrodes placed on the patient's chest to capture heart sound and electrical signals. The system processes these inputs to identify and characterize the amplitude and timing of S1 and S2 heart sounds, computing an estimated left ventricle Ejection Fraction (EF). The output is presented on a monitor for clinician review. The device serves as an adjunct to standard clinical evaluation, providing data that must be interpreted by a physician alongside other patient information. By offering a non-invasive estimate of EF comparable to 2-D echocardiography, the device assists in the assessment of cardiac function, potentially streamlining clinical decision-making.
Clinical Evidence
Two clinical studies were conducted: a measurement validation study and a measurement variability evaluation. The validation study enrolled 81 patients across four sites, comparing the ICR System to 2-D echocardiography and cardiac MRI (cMRI) to evaluate EF measurement agreement. Results demonstrated performance comparable to echocardiography. The variability study assessed operator and device performance, showing low and acceptable variability in EF measurements.
Technological Characteristics
The system consists of four acoustic sensors, ECG electrodes, a sensor application system, and a patient monitor. It utilizes external wearable sensors for non-invasive signal acquisition. The device is intended for point-in-time assessment in healthcare facilities. Materials are biocompatible for skin contact. The system performs signal processing and computation to derive EF values.
Indications for Use
Indicated for use in adults (≥18 years) for the estimation of left ventricle Ejection Fraction (EF) as an aid to physicians in evaluating heart function. Not for continuous monitoring or as a sole diagnostic means.

# 510(k) SUMMARY
{7}------------------------------------------------
#### SUBSTANTIAL EQUIVALENCE
The ICR System has the same intended use as the predicate devices of measuring cardiac function and specifically measuring EF like the Physioflow predicate. The indications for use for the ICR System are similar to those of the predicate devices with respect to the measurement of cardiac function. The differences in the technological characteristics between the devices do not raise different questions of safety or effectiveness as evaluated via bench, clinical and human factors testing. Thus, the ICR System is substantially equivalent to the predicate devices.
## PERFORMANCE DATA [807.92(b)]
Bench, clinical and human factors testing was conducted on the ICR System to support a determination of substantial equivalence.
## [807.92(b)(1)] Nonclinical Testing Summary:
The nonclinical, bench testing included:
- . Specification testing;
- Software Verification and Validation testing;
- Measurement reproducibility testing; and ●
- . Human Factors Testing.
The collective results of the nonclinical testing demonstrate that the ICR System meets the established specifications necessary for consistent performance during its intended use, which is equivalent to that of the predicate devices.
## [807.92(b) (2)] Clinical Testing Summary:
In support of the ICR System. two clinical studies have been performed, a measurement validation study and a measurement variability evaluation. The measurement validation study was performed to (1) evaluate the equivalence of the ICR System to the Echocardiography method and (2) to evaluate the agreement of the ICR System to cardiac Magnetic Resonance Imaging (cMRI) EF measurements, with cMRI being considered the gold standard for EF assessment. A total of 81 patients who arrived at the healthcare facility for some cardiac condition were enrolled across four (4) independent investigational sites. The study results demonstrate that the performance of the ICR system is comparable with the echocardiography method.
The measurement variability study addressed variability due to operator variability and device performance variability. The results of the study showed that the ICR System has low and acceptable variability in EF measurements.
## CONCLUSIONS [807.92(b)(3)]
The ICR System has the same intended use, a subset of the indication for use, and similar technological characteristics as the primary predicate device, the PhysioFlow. Both devices non-invasively measure hemodynamic flow and then compute and display EF values in numeric and graphical format. The devices leverage different means for measuring hemodynamic flow, however. The PhysioFlow was validated to measure EF
{8}------------------------------------------------
#### 510(k) SUMMARY
and the ICR System was verified to perform as intended and validated for measuring EF in direct comparison with the gold standard. Moreover, the method used by the ICR System has also been used with the Audicor secondary predicate device, which has the same intended use of measuring cardiac function parameters and has been cleared to do so safely and effectively. Lastly, like both predicate devices, the ICR System is to be used in adult patients by healthcare providers in the context of current standard of care for patient diagnosis and treatment. As such, the ICR System is substantially equivalent to the primary predicate device.
#### SUMMARY
The ICR System is substantially equivalent to the predicate devices.
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.
