Device Story
IntelliVue MX400/MX450 are multiparameter patient monitors (9" and 12" displays) designed for surgical, cardiac, medical, and neonatal care. Devices lack built-in sensors; they connect to external Philips measurement modules (e.g., M3001A, M3002A, gas modules) to acquire physiological signals (ECG, SpO2, NBP, CO2, etc.). Monitors process these inputs to display waveforms, trends, and values, and generate physiological/technical alarms. Used at bedside or during hospital transport by trained clinicians. Touch-screen interface, remote control, or mouse/keyboard input. Data management and connectivity to Central Station via LAN. Benefits include continuous patient status visibility and clinical decision support (e.g., ProtocolWatch, IPI) to aid provider assessment and intervention.
Clinical Evidence
No clinical data provided. Evidence consists of bench testing, including regression testing of physiological measurement parameters, alarm systems, battery functionality, and human interface. Environmental (temperature, humidity) and mechanical (shock, vibration, free fall) testing performed. Compliance with consensus standards (IEC 60601-1, 60601-1-2, 60601-1-8, 62304) verified.

The letters are black and appear to have a slightly distressed or textured effect, as if they have been printed on a rough surface. The word is presented in all capital letters and is horizontally oriented.
devices provide non-invasive and invasive measurements such as ECG with arrhythmia and ST, respiration, SpO2, NBP, invasive blood pressure, temperature, CO2, C.O., CCO.
The MX400 and MX450 acquire multiple physiological patient signals (via connected external measurement modules), display measurement values, waves and trends, generate physiological and technical alarms, provide data recording and support patient data management.
The MX400 and MX450 offer a monitoring solution optimized for the surgical, cardiac, medical and neonatal care environments. They are located in the patient vicinity either at the bedside or used mobile, during patient transport in the hospital.
The MX400 and MX450 have a color display with touch-screen as primary input device. They also support a specialized remote control, keyboard and pointing devices such as a mouse.
The MX400 and MX450 interact with the connected external measurement devices locally at the bedside or in transport situations and with the Central Station via LAN.
- న. Intended Use
The subject devices IntelliVue Patient Monitor MX400 and MX450 have the same intended use as the legally marketed predicate IntelliVue Patient Monitor MP30.
The monitors are indicated for use by health care professionals whenever there is a need for monitoring the physiological parameters of patients.
The monitors are intended to be used for monitoring and recording of, and to generate alarms for, multiple physiological parameters of adults, pediatrics, and neonates. The monitors are intended for use by trained healthcare professionals in a hospital environment.
The monitors are additionally intended for use in transport situations within hospital environments.
The monitors are only for use on one patient at a time. They are not intended for home use. Not therapeutic devices. The monitors are for prescription use only.

{3}------------------------------------------------
### 6. Technological Characteristics
The subject devices IntelliVue Patient Monitors MX400 and MX450 have the same range of functions as the legally marketed predicate IntelliVue Patient Monitor MP30. MX400 and MX450 reuse unchanged external measurement modules and measurement accessories as already used by the predicate MP30.
MX400 and MX450 have the same relevant-technological characteristics as the predicate MP30 with regard to energy sources, portability, user interface, and robustness.
Compared to the predicate MP30, the MX400 and MX450 have modified technological characteristics with regard to the usage of state of the art hardware components such as widescreen display, CPU, memories and interfaces, regarding a more compact form factor, resulting in slightly different dimensions and weight, regarding environmental conditions and operating time with internal battery.
The housing of the MX400 and MX450 is made of plastic whereas the housing of the predicate IntelliVue Patient Monitor MP30 is made of plastic and partly of magnesium alloy. Biocompatibility aspects are not affected because the devices do not have contact with patients. The MX400 and MX450 reuse plastic materials of the predicate MP30.
The fundamental scientific technology of the new IntelliVue Patient Monitors MX400 and MX450 is the same as that of the predicate IntelliVue Patient Monitor MP30. The differences in technological characteristics between the subject devices MX400 and MX450 and the predicate device MP30 do not diminish 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.
