Indications for Use
The Spacelabs Medical Ultraview Digital Telemetry System, when used in conjunction with a Spacelabs Medical PCMS Patient Monitor or Ultraview Care Network, provides a means for the continuous monitoring of electrocardiographic signals in order to detect abnormal cardiac rhythms, including life-threatening events such as high and low heart rates, asystole, and ventricular fibrillation. Optionally, on adult patients, additional abnormal cardiac rhythms, such as ventricular runs, tachycardia, and ST segment deviations are detected. The Ultraview Digital Telemetry System also provides a means for the episodic monitoring of noninvasive blood pressure (NIBP) signals to detect abnormal events such as high and low blood pressure. The System also provides a means for both continuous and episodic monitoring of pulse blood oxygen saturation signals in order to detect desaturation caused by abnormal pulmonary/circulatory functions. The Spacelabs Medical Ultraview Digital Telemetry System Models 90343 and 90347 are intended for use with either adult or neonatal patient populations in a hospital environment. When the NIBP option is selected in the Model 90343 configuration, the NIBP feature is to be used with adult patient populations only.
Device Story
Wireless multi-parameter telemetry system for hospital use; monitors ECG, SpO2, and NIBP. System comprises battery-operated transmitter (Model 90343/90347), receiver module, and antenna. Transmitter acquires physiological signals via electrodes/sensors; transmits raw ECG or preprocessed SpO2/NIBP data to modular receiver via VHF. Receiver processes data for alarm generation and display on Spacelabs PCMS monitor or Ultraview Care Network. Clinicians use system to remotely monitor patient status, review waveforms/numerics, and detect abnormal cardiac rhythms or physiological events. Enables transport of patients while maintaining monitoring. Output facilitates clinical decision-making by providing real-time alerts and trend data, potentially improving patient safety through early detection of life-threatening events.
Clinical Evidence
Bench testing only. System performance verified through functional requirements testing and safety testing per industry standards, including ANSI/AAMI EC13 and AAMI ECAR-1987.
Indicated for continuous ECG monitoring to detect arrhythmias (e.g., high/low heart rate, asystole, V-fib) in adult and neonatal patients in hospital settings. Optionally detects ventricular runs, tachycardia, and ST segment deviations in adults. Also provides episodic NIBP monitoring (adults only) and continuous/episodic SpO2 monitoring for desaturation detection.

The devices subject to this submission are the Models 90343, 90347, and 90478. Each Ultraview Digital Telemetry System configuration consists of a battery-operated Telemetry Transmitter, a Receiver Module, and an antenna system. The Ultraview Digital Telemetry Multi-Parameter Transmitter Model 90343 is a wideband VHF unit that provides 5electrode ECG and continuous or episodic SpO2 monitoring capabilities, with an optional noninvasive blood pressure (NIBP) interface when connected to a Spacelabs Medical Model 90217Ambulatory Blood Pressure (ABP) Monitor (K855127). The Ultraview Digital Telemetry ECG Transmitter Model 90347 is identical to the Model 90343 with the SpO2 measurement function and ABP communications capabilities removed.
The Ultraview Digital Telemetry System interfaces to a patient using standard accessories including ECG electrodes and lead wires, NIBP hoses and cuffs, SpO2 cables and sensors, and adapter cables to connect these accessories to the Transmitter. The telemetry system sends raw ECG vectors or preprocessed SpO2 and NIBP data, based upon the capability of the selected Transmitter, to the VHF version of the Model 90478 Modular Receiver via a diversity antenna system.
The Modular Receiver collects and processes parameter specific physiologic data for alarm generation and display of numeric values and waveforms on a Spacelabs Medical Patient Care Management System (PCMS) Monitor or Ultraview Care Network via SDLC communications. The monitor provides the display, review, editing and analysis capabilities for the care provider. Hard copy records may be provided by the wide variety of Spacelabs Medical printers and recorders that can be interfaced by either Ethernet or SDLC communications.
- 5. Intended Use The Spacelabs Medical Ultraview Digital Telemetry System, when used in conjunction with a Spacelabs Medical PCMS Patient Monitor or Ultraview Care Network, provides a means for the continuous
{3}------------------------------------------------
monitoring of electrocardiographic signals in order to detect abnormal cardiac rhythms, including lifethreatening events such as high and low heart rates, asystole, and ventricular fibrillation. Optionally, on adult patients, additional abnormal cardiac rhythms, such as ventricular runs, tachycardia, and ST seqment deviations are detected.
The Ultraview Digital Telemetry System also provides a means for the episodic monitoring of noninvasive blood pressure (NIBP) signals to detect abnormal events such as high and low blood pressure. The System also provides a means for both continuous and episodic monitoring of pulse blood oxygen saturation signals in order to detect desaturation caused caused caused by abnormal pulmonary/circulatory functions.
The Spacelabs Medical Ultraview Digital Telemetry System Models 90343 and 90347 are intended for use with either adult or neonatal patient populations in a hospital environment. When the NIBP option is selected in the Model 90343 configuration, the NIBP feature is to be used with adult patient populations only.
- 6. Comparison of We consider the Ultraview Digital Telemetry System Technological to be substantially equivalent to a combination of Characteristics systems currently marketed by Spacelabs Medical and, for the integration of physiological parameters into a telemetry system, to the Hewlett Packard System Model Number M2600A. The design, components, storage technology and energy source are similar to its predicate devices. The comparable systems all provide a means for interfacing with a patient, collecting parameter specific physiologic data, and processing the data for alarm generation and display of numeric values and waveforms on a bedside or central monitoring system.
The only significant differences between the Medical Ultraview Digital Telemetry Spacelabs System and the comparable systems are in the physiologic feature sets offered by each of the systems and in the hardware packaging of the multi
{4}------------------------------------------------
parameter feature sets of the Ultraview Digital Telemetry Transmitters into one modular unit designed to be compatible with the existing Patient Care Monitoring System (PCMS) and Ultraview Care Network currently offered by Spacelabs Medical.
- 7. Testing The Spacelabs Medical Ultraview Digital Telemetry System will be subject to extensive safety and performance testing prior to release. Final testing for the system includes various performance tests designed to ensure that the device meets all of its functional requirements and performance specifications. Safety testing has been or will be performed by third party agencies to ensure the device complies to applicable industry and safety standards. The Ultraview Digital Telemetry System will also be tested to assure compliance to the requirements of various standards, including ANSI/AAMI EC13 and AAMI ECAR-1987.
In conclusion, the Spacelabs Medical Ultraview Digital Telemetry System is as safe and effective as its predicate devices and raises no new issues.

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.
