APR 25 1997
Nature’s Cradle® C2000 Series, when used as directed, is an infant motion and sound system designed to closely simulate the mother’s heartbeat and circulatory system familiar to the infant during the last trimester of pregnancy. This provides a transition to infants after birth, allowing them to grow accustomed to their new environment at a pace that minimizes stress. Nature’s Cradle® C2000 Series can be used with Infant Advantage® approved bassinets and hospital nursery tubs or bassinets. Nature’s Cradle® C2000 Series is indicated for healthy, full term infants at home or hospital.
Nature’s Cradle® C2000 Series uses the same motion and the same sound as predicate devices, Nature's Cradle® Model C1500, Premarket Notification # K960747, and Nature's Cradle® Model M-1, Premarket Notification # 901763. Nature’s Cradle® C2000 Series uses the same mechanism as predicate device, Nature's Cradle® Model C1500, Premarket Notification # K960747.
The size of the moving platform of Nature’s Cradle® C2000 Series has been reduced to allow the plastic case (containing mechanism and moving platform) to fit Infant Advantage® approved bassinets and hospital nursery tubs/bassinets.
Contrary to predicate devices (Nature's Cradle® Model C1500, Premarket Notification # K960747), the mechanism is no longer embedded in a 4 1/2” high mattress, or cabinet with 2” high mattress (Nature's Cradle® Model M-1, Premarket Notification # K901763). The modification of Nature's Cradle® C2000 Series makes the mechanism a stand alone device weighing approximately 5 pounds that is covered with a 1” high mattress.
Contrary to predicate devices, Nature's Cradle® Model C1500, Premarket Notification # K960747 and Nature's Cradle® Model M-1, Premarket Notification # K901763 which are intended to be used at home only, the new Nature's Cradle® C2000 Series can be used for healthy, full term infants at home or hospital from 0 - 16 weeks. The fundamentals of the principles remain the same as with predicate devices, Nature's Cradle® Model C1500, Premarket Notification # K960747, and Nature's Cradle® Model M-1, Premarket Notification # K901763.
The mechanism of Nature's Cradle® C2000 Series is connected to the same control module and the same low voltage wall-mount transformer as predicate device, Nature's Cradle® Model C1500, Premarket Notification # K960747.

# 16. 510(k) SUMMARY, continued
A mattress is provided separately and placed on top of the platform, the same as predicate device, Nature's Cradle® Model M-1, Premarket Notification # K901763. To further enhance the safety of the device, the fitted sheet is placed over the top of the bassinet or tub and secured with a cord. To further enhance the safety of the device, the fitted sheet is placed over the top of the bassinet or tub and secured with a cord. This feature keeps the infant in a “Hammock”-like surrounding, on the mattress, and away from the walls of the bassinet or tub. Furthermore, the Nature’s Cradle® C2000 Series includes the same safety checks in the mechanism as predicate devices, Nature's Cradle® Model C1500, Premarket Notification # K960747, and Nature's Cradle® Model M-1, Premarket Notification # K901763: any excessive weight or obtrusion of the moving platform will immediately stop the mechanism.
All components of Nature’s Cradle® C2000 Series are non-sterile and reusable.
The Nature’s Cradle® C2000 Series has the same device classification product code (80FMS), the same technology and fundamentals of principles, and the same indications for use as legally marketed, predicate devices, Nature's Cradle® Model C1500, Premarket Notification # K960747, and Nature's Cradle® Model M-1, Premarket Notification # K901763.
Laboratory and bench testing of predicate device, Nature's Cradle® Model C1500, Premarket Notification # K960747 demonstrated the device to be safe and effective when used as described. The new Nature's Cradle® C2000 Series has not been modified significantly and has the same fundamentals of principles as predicate device, Nature's Cradle® Model C1500, Premarket Notification # K960747, except for a smaller size platform. This change does not require additional testing and reliability data was submitted with predicate device, Nature's Cradle® Model C1500, Premarket Notification # K960747 and is included in Section 18, Attachment IV.
A clinical trial, published in the Journal of Perinatology Vol. 15, No. 3, 1995, involving 90 full term infants was performed at Kaiser Medical Center, Santa Clara, CA. The infants were evaluated utilizing the Brazelton Neonatal Behavior Assessment Scale. The study found that infants who sleep in the Nature’s Cradle® environment were more adaptive, less irritable, and cried approximately 65% less. Additionally, they were more attentive, and alert, slept for longer periods, and slept through the night sooner, plus experienced a lower incidence of colic when compared to the control group.

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.
