Indications for Use
The ivWatch Model 400 is indicated for the detection of subcutaneous infiltrations and extravasations of 10 cc or less of optically clear infusates, as an adjunctive device to the clinical evaluation in the healthcare setting of adults and pediatrics with peripherally-inserted catheters (PIVs). The device is indicated to assess patients for the subcutaneous infiltrations and extravasations but should not serve as a substitute for regular clinician assessment of the PIV site. The ivWatch Model 400 is intended for use by healthcare practitioners who have been trained in the use of the device.
Device Story
The ivWatch Model 400 provides continuous, non-invasive monitoring of tissue near PIV insertion sites to detect infiltration/extravasation. The system comprises a patient monitor (IPM), a reusable optical sensor cable, and a single-use sensor receptacle. The IPM emits visible and near-infrared light through the cable to the skin and measures reflected light. An internal signal processing algorithm analyzes changes in optical properties to identify infusate pooling in subcutaneous tissue. If an event is detected, the device triggers audible and visual notifications for the clinician. Used in healthcare settings by trained practitioners, the device aids in early detection, allowing for timely intervention to potentially reduce patient harm from infiltration. The subject device adds an RFID tag to the sensor cable for tracking useful life (replacing a USB method) and expands the indicated patient population to include pediatrics.
Clinical Evidence
Clinical study in pediatric patients (2 weeks to 17 years, weight 3.3-196.7 kg) evaluated performance. The device detected 80.0% of infiltrations (95% CI [51.9% to 95.7%]) before clinician detection. In a blinded non-alarming group, sensitivity was 78.3% (95% CI [56.5% to 92.5%]). Average detection time was 29.8 hours prior to clinician diagnosis. No serious adverse events occurred. Results support equivalence to adult clinical data.
Technological Characteristics
System includes IPM, reusable optical sensor cable, and single-use EO-sterilized sensor receptacle (ISO 11135-1). Uses visible/near-infrared light sensing. RFID tag (ISO 15693) for cable life tracking. Compliant with IEC 60601-1-2 (EMC), ANSI/AAMI ES60601-1 (Electrical Safety). Sensor cable is MR Conditional (ASTM F2052-15, F2213-06-11, F2119-07-13, F2182-11a). Biocompatibility per ISO 10993-1, -5, -10.
Indications for Use
Indicated for detection of subcutaneous infiltrations and extravasations (≤10 cc) of optically clear infusates in pediatric and adult patients with peripherally-inserted catheters (PIVs). Adjunctive to clinical assessment; not a substitute for regular clinician site inspection. For use by trained healthcare practitioners.

# Device Description
The ivWatch Model 400 is a medical device that provides continuous, non-invasive monitoring of human tissue adjacent to peripheral intravenous (PIV) insertion sites to aid in the early detection of infiltration and extravasation events. The ivWatch Model 400 consists of the ivWatch Patient Monitor (IPM), a reusable optical sensor cable and a single-use sensor receptacle.
The ivWatch Model 400 uses visible and near-infrared light to measure changes in the optical properties of the tissue near a PIV insertion site. The IPM contains an optical system that generates visible and near-infrared light signals that are sent through the optical sensor cable to the patient's skin. Simultaneously, the IPM measures the light reflected back through the optical sensor cable from the patient's skin. Measured changes between the emitted and reflected signals are processed by the ivWatch signal processing algorithm to determine if an infiltration event may have occurred. If changes in the optical properties of the tissue near the PIV insertion site are consistent with an infusate pooling in the subcutaneous tissue, the IPM emits audible and visual notifications intended to prompt the clinician to inspect the PIV site for a possible infiltration event.
### Indications for Use 1.5
The ivWatch Model 400 is indicated for the detection of subcutaneous infiltrations and extravasations of 10 cc or less of optically clear infusates, as an adjunctive device to the clinical evaluation in the healthcare setting of adults and pediatrics with peripherally-inserted catheters (PIVs). The device is indicated to assess patients for subcutaneous infiltrations and extravasations but should not serve as a substitute for regular clinician assessment of the PIV site. The ivWatch Model 400 is intended for use by healthcare practitioners who have been trained in the use of the device.
# 1.6 Comparison of the Subject Device to the Predicate Device
The subject device (ivWatch Model 400) is a modification to the legally marketed ivWatch Model 400 (K153605). The subject and predicate devices consist of the same components including the ivWatch Patient Monitor, a single-use sensor receptacle and a reusable optical sensor cable. The subject and predicate devices have the same intended use which is to aid in the detection of infiltrations and extravasations during peripheral IV infusion therapy. The subject and predicate devices have the same technological characteristics and principles of operation and there have been no significant changes to the design or materials of the subject device.
This submission includes labeling modifications to the indications for use and to the MR safety information and the addition of an RFID tag in the sensor cable to track sensor cable useful life. The indications for use has been revised to extend the target patient population from patients 18 years old or greater to a patient population including both pediatrics and adults. Clinical performance testing on the pediatric patient population under the age of 18 years demonstrates that the subject device is as safe and effective as the predicate device on patients 18

# 1.7.6 Performance Testing - Clinical
The predicate device submission included the clinical evaluation of the Model 400 in patients 18 years old or greater. The purpose of this 510(k) submission is to extend the Model 400 indications for use from patients 18 years old or greater to a target patient population including both pediatrics and adults. The pediatric IRB approved clinical study included in this submission demonstrates that the Model 400 is just as safe and effective in the pediatric population under the age of 18 years old as the use of the predicate device in the adult population. Safety and efficacy of the Model 400 has been demonstrated in accepted case studies representing an age distribution from 2 weeks to 17 years, patient weight measurements from 3.3 to 196.7 kg (mean, 34.5 kg), distributed skin pigmentations and similar proportions between male and female subjects.
The clinical validation studies in the pediatric population under the age of 18 years old assessed the performance (e.g. time difference between ivWatch detection and clinician detection of an infiltration, sensitivity and specificity) of the ivWatch Model 400. The ivWatch Model 400 detected 80.0% of infiltrations (95% Cl [51.9% to 95.7%) before detection by a clinician. There were no serious adverse events during the clinical study. Clinical results demonstrate that the ivWatch Model 400 is equivalent in the pediatric population as compared to the adult population.

# 1.8 Conclusions
The technological characteristics and principles of operation of the ivWatch Model 400 and the predicate device are the same. The clinical data provided in the submission supports the expansion of the indications for use to now include the pediatric patient population.
The results of the clinical study and performance testing indicate that the ivWatch Model 400 is substantially equivalent to the ivWatch Model 400 (K153605). The ivWatch Model 400 performs as intended and is substantially equivalent to the legally marketed predicate device.

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.
