Safety, performance, and risk/benefit ratio
Indications for Use
The Kendall SCD Compression System is designed to increase venous blood flow in at risk patients, including bariatric and morbidly obese patients, in order to help prevent deep vein thrombosis and pulmonary embolism.
Device Story
Sequential Compression Comfort Sleeves are single-patient-use, disposable pneumatic limb sleeves. They function as a component of the Kendall SCD Compression System, connecting to SCD Controllers (Express, Response, or Sequel) via 3-lumen tubing. Controllers deliver intermittent, sequentially gradient pneumatic pressure to leg bladders to increase venous blood flow. Sleeves feature a 'pillowcase' design with PVC bladders covered by polyester mesh and wickable fabric. Available in knee, thigh, and thigh Tear-Away styles; Tear-Away allows conversion between lengths without sleeve replacement. A low-profile connector enables disengagement for patient ambulation. Used in clinical settings by healthcare professionals to prevent DVT and PE in at-risk patients, including bariatric/morbidly obese populations. Output is mechanical compression; clinical benefit is reduced risk of venous thromboembolism.
Clinical Evidence
Bench testing included functional and performance verification and hemodynamic testing on healthy human subjects. Clinical evidence relies on a review of published and unpublished literature regarding intermittent pneumatic compression (IPC) systems, which have been used clinically for over twenty years. The review confirmed an acceptable risk/benefit ratio, substantiated labeling claims, and demonstrated that the technology, performance, and safety profile are consistent with the state of the art for IPC devices.
Technological Characteristics
Materials: PVC bladders, polyester mesh, and wickable polyester fabric. Sensing/Actuation: Pneumatic compression via external controller. Form factor: Disposable limb sleeves (knee/thigh/tear-away). Connectivity: 3-lumen tubing with low-profile connector to SCD controllers. Standards: ISO 10993-1 (Biocompatibility), ISTA 2A (Packaging).
Indications for Use
Indicated for at-risk patients, including bariatric and morbidly obese individuals, to increase venous blood flow and help prevent deep vein thrombosis (DVT) and pulmonary embolism (PE).

### Contact Person 1.
Mia Proli Manager, Regulatory Affairs (508) 261-8037
### 2. Name of Medical Device
Classification Name: Sleeve, Limb, Compressible Kendall SCD™ Sequential Compression Comfort Sleeves Proprietary Name:
### 3. Identification of Legally Marketed Device
The proposed devices, Sequential Comfort Sleeves, are identical in intended use, function and mode of operation to the SCD Express System Sleeves (K040511); SCD Express Tear-Away Sleeves (K040649) and SCD Large/X-Large Knee and Thigh Sleeves (K051805).
#### 4. Device Description
The proposed devices, Sequential Compression Comfort Sleeves, are the compressible limb sleeve component of a pneumatic compression system for applying pressure to a patient's leg for the prevention of deep vein thrombosis (DVT) and pulmonary embolism (PE).
Sequential Compression Comfort Sleeves are compatible with the SCD Express Controller (K040511), SCD Response Controller (K992079) and SCD Sequel Controller (K942664), collectively referred to as SCD Controllers. SCD Controllers provide air to the sleeves through tubing connected to each bladder of the sleeve delivering an intermittent, sequentially gradient pneumatic pressure to the limb. The controller system monitors the pressure in the bladders and releases the pressure by venting the air from the sleeve bladders through a valve system within the controllers.
The proposed single-patient-use, disposable sleeves are available in knee, thigh and thigh Tear-Away styles. The Tear-Away function allows the clinician to convert the patient from a thigh length sleeve to a knee length sleeve without changing to a new sleeve. TThe sleeve connects to a controller via a 3-lumen tubing set. The tubing set connects to the sleeve via a low-profile connector that can be disengaged to allow for patient ambulation without sleeve removal.

# K100306: Kendall SCD Sequential Compression Comfort Sleeves
## ട. Device Intended Use
The Kendall SCD Compression System is designed to increase venous blood flow in the at risk patient, including bariatric and morbidly obese patients, in order to help prevent deep vein thrombosis and pulmonary embolism.
## 6. Product Comparison
The proposed devices, Sequential Comfort Sleeves, are identical in intended use, function and mode of operation to the SCD Express System Sleeves (K040511): SCD Express Tear-Away Sleeves (K040649) and SCD Large/X-Large Knee and Thigh Sleeves (K051805).
The predicate SCD Sleeves are constructed of two layers of non-woven polyester laminated to a thin film of PVC that are welded together to form bladders. Tubes are attached to the bladders via rigid PVC inlet ports which are welded to the laminate material. To make the sleeves more comfortable, the proposed Comfort Sleeves will be constructed of four layers; two lavers of non-laminated PVC welded together to form bladders with covers made from both a polyester mesh fabric and a wickable polyester fabric, which form a "pillowcase" around the bladders. In this design, the tubing will be welded into the bladders, beneath the sleeves, without the use of an inlet port.

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.
