Class 2
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, uncolored infusates, as an adjunctive device to the clinical evaluation in the hospital setting of patients 18 years old or greater with peripherally-inserted IVs (PIVs) on the forearm or dorsal aspect of the hand. 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 physicians, or under the direction of a physician, who have been trained in the use of the ivWatch Model 400.
Device Story
Device provides continuous, noninvasive monitoring of tissue near PIV insertion sites to detect infiltration/extravasation. System comprises ivWatch Patient Monitor (IPM), reusable optical sensor cable, and single-use sensor receptacle. IPM emits visible and near-infrared light through cable to skin; measures reflected light. Proprietary signal processing algorithms analyze changes in optical properties to identify infusate pooling. If infiltration detected, IPM triggers audible/visual notifications for clinician inspection. Used in hospital settings by trained physicians or under physician direction. Output aids clinical decision-making by providing early warning of potential infiltration events, potentially benefiting patients by reducing complications associated with extravasation.
Clinical Evidence
No clinical data. Bench testing only. Biocompatibility testing (sensitization, irritation, cytotoxicity) per ISO 10993-10:2010 and ISO 10993-5:2009 passed. Reprocessing validation (low-level disinfection and cleaning) per AAMI TIR12-2010 and AAMI TIR30-2011 passed.
Technological Characteristics
System includes IPM, reusable optical sensor cable, and single-use sensor receptacle. Sensor cable sheathing uses Pellethane 80AE with 2.7% Propell and Pantone 646C colorant. Sensing principle: visible and near-infrared light reflectance. Connectivity: proprietary signal processing. Sterilization/Reprocessing: low-level disinfection and cleaning validation per AAMI standards.
Indications for Use
Indicated for detection of subcutaneous infiltrations and extravasations (≤10 cc) of optically clear, uncolored infusates in hospital patients ≥18 years old with PIVs on the forearm or dorsal hand. Adjunctive to clinical assessment; not a substitute for regular site inspection.

# 7.4 Device Description
The ivWatch Model 400 is a medical device that provides continuous, noninvasive monitoring of human tissue adjacent to peripheral intravenous (PIV) insertion sites on the forearm and dorsal aspect of the hand 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 signal are processed by proprietary ivWatch signal processing algorithms to determine if an infiltration event may have occurred. If changes in the optical properties of the tissue near the peripheral IV 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 peripheral IV site for a possible infiltration event.
#### Indications For Use 7.5
The indications for use are identical to the predicate device.
The ivWatch Model 400 is indicated for the detection of subcutaneous infiltrations and extravasations of 10 cc or less of optically clear, uncolored infusates, as an adjunctive device to the clinical evaluation in the hospital setting of patients 18 years old or greater with peripherally-inserted IVs (PIVs) on the forearm or dorsal aspect of the hand. 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 physicians, or under the direction of a physician, who have been trained in the use of the ivWatch Model 400.
## 7.6 Comparison of Modified Device with the Predicate Device
The subject device has the same technological characteristics and intended use as compared to the predicate device (K142374). The ivWatch Model 400 consists of the ivWatch patient monitor, a single-use sensor receptacle and a reusable optical sensor cable. There have been no changes to the ivWatch patient monitor and the single-use sensor receptacle of the subject device compared to the predicate device submission. The sensor cable of the subject device is the only component of the ivWatch Model 400 that has been modified. Specifically, the sensor cable sheathing, which is the outer protective layer encasing the flexible glass fibers, has been modification of the subject device's sheathing includes removing an additive and changing the colorant.

#### Performance Data 7.7
ivWatch has performed the following non-clinical/design verification testing based on the risk analysis conducted. The 510(k) submission included a summary of these design control activities to assure that the risks were adequately mitigated. The risks identified included biocompatibility and reprocessing. The mitigation for biocompatibility risks was to repeat the testing that was previously performed on the sensor cable sheathing of the predicate device per ISO 10993-1: Biological evaluation of medical devices, Part 1: Evaluation and testing. The reprocessing risks were mitigated by repeating the low-level disinfection validation and cleaning validation that was performed on the sensor cable of the predicate. The results of these tests demonstrate that the sensor cable modification of the ivWatch Model 400 is substantially equivalent to the sensor cable of the predicate device based on predetermined acceptance criteria. Clinical testing was not required for this submission.

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.
