Device Story
S9 Greenhills is a blower-based positive pressure system with integrated heated humidifier; provides adaptive servo-ventilation (ASV) therapy. Input: patient's instantaneous ventilation; device calculates target ventilation based on recent average minute ventilation. Operation: microprocessor-controlled blower adjusts pressure support (PS) and expiratory positive airway pressure (EPAP) to servo-control ventilation to meet target. Modes: CPAP, ASV, ASVAuto. Used in home or hospital; operated by patient or clinician. Output: controlled positive airway pressure (3-25 cmH2O). Clinician uses output to stabilize ventilation during sleep; benefits patient by treating OSA, central/mixed apneas, or periodic breathing.
Clinical Evidence
Bench testing only. Side-by-side testing compared S9 Greenhills to S9 VPAP Adapt (K113801) across therapy modes, verifying pressure stability and response to apneas, flow limitations, snore, and periodic breathing. No clinical studies required.
Indicated for patients >66 lb (30 kg) with obstructive sleep apnea (OSA), central/mixed apneas, or periodic breathing. Intended for home and hospital use.
Regulatory Classification
Identification

{1}------------------------------------------------
#### Indication for Use
The S9 Greenhills is indicated for the treatment of patients weighing more than 66 lb (30 kg) with obstructive sleep annea (OSA), central and/or mixed apneas, or periodic breathing.
It is intended for home and hospital use.
#### Substantial Equivalence
The new device has the following similarities to the previously cleared predicate devices.
- t Same intended use
- t Same operating principle
- t Similar technologies
- Same manufacturing process .
Design and Verification activities were performed on the S9 Greenhills System as a result of the risk analysis and design requirements. "All tests (predicate bench testing) confirmed the product met the predetermined acceptance criteria. ResMed has determined that the new device has not altered the safety and effectiveness of CPAP/Bilevel treatment for patients with Obstructive Sleep Apnoea (OSA), central and/or mixed apneas, or periodic breathing who weigh more than 66 Ib (>30 kg).
Predicate bench testing and clinical studies were used to show substantial equivalence between the S9 VPAP Adapt (K113801) and S9 Greenhills.
The new device complies with the applicable requirements referenced in the FDA guidance documents:
- . FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 11, 2005)
- FDA Draft Guidance for Industry and FDA Staff Design Considerations for Devices Intended for ◆ Home Use- Document Issued on: December 12, 2012
- FDA Draft Guidance for Industry and FDA Staff Radio Frequency Wireless Technology in . Medical Devices - Document Issued on: August 13, 2013
- Reviewer Guidance for Premarket Notification Submissions, ARDB, CDRH, FDA, November . 1993.
#### Clinical Testing:
Clinical testing is not required, bench testing alone is sufficient to demonstrate the product remains substantially equivalent to the predicate device S9 VPAP Adapt (K113801).
### Non-Clinical Testing:
Side-by-Side bench testing was performed to verify that the S9 Greenhills met the predetermined pass/fail requirements of the S9 Greenhills System Specification when compared to the predicate devices [S9 VPAP Adapt (K113801)]. This bench testing included testing the performance of each therapy mode which included:
- . Pressure stability
- Response to apneas .
- Response to flow limitations and snore. .
- Response to periodic breathing .
{2}------------------------------------------------
A breathing machine simulates patient breathing patterns, which results in the Flow Generator responding in a manner consistent with maintaining the CPAP treatment pressure (CPAP mode) or adjusting the pressure support (PS) in (ASV mode) and adjusting the pressure support (PS) and EPAP in (ASVAuto mode) based upon the patient's condition. The clinical Pass/Fail requirements are traced to the S9 Greenhills System Specification and to the predicate device's performance
The S9 Greenhills has been tested to appropriate FDA consensus standards and other applicable requirements passing all test protocols. The S9 Greenhills with and without the integrated heated humidifier was designed and tested according to:
- FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 11, 2005)
- FDA Draft Guidance for Industry and FDA Staff Design Considerations for Devices . Intended for Home Use- Document Issued on: December 12, 2012

- Reviewer Guidance for Premarket Notifications, ARDB, CDRH, FDA, 。 November 1993.
#### Device Description
The S9 Greenhills is similar to the predicate device(s), using a blower based positive pressure system with an integrated heated humidifier and heater controller. The device platform is identical to the S9 VPAP Adapt (K113801) and contains a Micro-processor controlled blower system that generates controlled positive airway pressure between 3-25 cmH2O. The system comprises the flow generator, patient tubing, mask (patient interface) and humidifier.
The S9 Greenhills is a flow generator device designed to provide adaptive servo-ventilation therapy (ASV mode) or (ASVAuto mode) to stabilize a patient's ventilation during sleep. The device continually measures the patient's instantaneous ventilation, and calculates a target ventilation based on to the patient's recent average minute ventilation. It then adjusts the degree of pressure support to servo-control the patilation to at least equal the target ventilation. The same is true for ASVAuto mode except the EPAP is adjusted to address any obstructive apneas detected.
Therapy modes contained in the S9 Greenhills are CPAP, ASV, and ASVAuto and unchanged from the S9 VPAP Adapt (K102586). They are:
- . CPAP mode - the device delivers a continuous positive airway pressure throughout the entire therapy session;
- ASV mode the device automatically adjusts pressure support in response to the . patient's recent average minute ventilation; and
- ASVAuto mode the device automatically adjusts pressure support in response to . the patient's recent average minute ventilation and EPAP level for OSA events.
The functional characteristics of the S9 Greenhills system includes all the clinician and user friendly features of the predicate device which have been verified during usability studies in accordance with IEC 62366 Medical devices - Application of usability engineering to medical devices.

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.
