The Express MD Electronic House Call™ System is comprised of a home unit, legally marketed diagnostic peripherals, and a server. The home unit is a communications device that collects data from the diagnostic peripherals and the
{1}------------------------------------------------
patient in the home and transmits the data to the server over the home's existing telephone line or other identified method (existing high-speed connection in patients' home). The diagnostic peripherals comprise a wide range of legally marketed medical electronic devices capable of measuring patient parameters such as blood pressure, pulse rate, weight, etc. The server application responds to calls from the home units, collects the data, and then compares the data to preset The healthcare practitioners and privileged users access the server thresholds. through a secure website.
If a patient is found to be outside of a pre-set parameter, the healthcare practitioner will respond according to their set policies. In addition, an email will be sent to the clinician. This email indicates that the nurse/clinician should review the website. This is not a real time alert or an alarm but an email that does not identify a patient, parameter or clinical state.
#### 5. INTENDED USE

The Electronic House Call™ Device together with the Electronic House Call™ Application is intended to be a simple "store and forward" communications platform that allows clinicians and authorized users to access a patients' information for review through the Electronic House Call™ website. The Electronic House Call™ Device is a tool to monitor patients remotely and motivate them through education and reminders. The Electronic House Call™ System allows patients to measure vital signs without assistance from their healthcare provider. The Electronic House Call™ System is not intended to replace existing treatments or consultations, nor is it to be used as a substitute for a qualified healthcare professional's judgment or treatment plan. The Electronic House Call™ System is not intended to act as an emergency response system.
#### 6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE
The proposed Electronic House Call™ System and the predicate devices all consist of a home unit, peripheral devices, and a secure website. Both the proposed and predicate devices connect to a telephone line at the subject's home or assisted living The peripheral devices that are compatible with the Electronic House facility. Call™, the Neptec System, the RTX device and Health Buddy System include non-
{2}------------------------------------------------
invasive blood pressure cuffs, patient weight scales, and blood glucose meters. The proposed Electronic House Call™ System and the predicate Health Buddy devices are simple, user friendly devices that connect to a standard home telephone line. In addition to the standard phone line, the proposed Electronic House Call™ can connect to a Cingular 8525 cell phone or existing high-speed Ethernet line. These transmission protocols have been validated and do not affect safety or effectiveness of the device. The proposed and predicate device screens display information, take vital signs, and ask questions about symptoms and behaviors. Both the Electronic House Call™ System and the Health Buddy predicate devices provide education and reinforcement to the patient while delivering evaluation by a medical professional. Both the proposed Electronic House Call™ System and the RTX DLM112 Daylink Monitor include the option of communication using ECG systems. This option provides the user the ability to transmit ECG data from legally marketed ECG devices using standard digital communication technologies to the healthcare provider. This feature of the proposed and predicate devices does not raise any safety or effectiveness issues since verification and validation testing have been performed to support the function and compatibility of the ECG with the Electronic House Call™ System.
Like the proposed Electronic House Call™ System, the Health Buddy System includes software to record patient information and devices designed to receive information from the peripheral devices and then transfer the information to a secure website.
Additionally, a comparison of the intended use and technical characteristics of the proposed device with the Suntech Advantage Model 2 Blood Pressure kit and the Nonin IPod and their predicate devices demonstrates that the Electronic House Call™ System is substantially equivalent to both the ZOLL M-Series NIBP Option and the ZOLL E Series devices which utilize the Suntech Advantage Model 2 Blood Pressure kit and the March Healthcare HMK device which utilizes the Nonin iPod.
#### 7. PERFORMANCE TESTING

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.
