#### substantial equivalence is claimed: Dideco-Shiley Autotransfusion Accessories (K872159)
### Intended Use:
The ATS Suction Line is a suction line to aspirate and anticoagulate blood from the surgical field into an autotransfusion reservoir with ¼" suction port connected to a vacuum source.
The ATY Y-Adapter is a Y-Adapter to connect two autotransfusion reservoirs with 1/4″ female outlet connector to an autotransfusion device.
The ATO Oxygenator Line is a tubing system to connect an oxygenator with 1/4´´ male connector to an autotransfusion device: - via a Y-adapter connected to an autotransfusion reservoir; or
- directly to the autotransfusion device accepting a 1/4´´ female connector; or via an autotransfusion reservoir.
## Device Features:
The ATS Suction Line consists of a double lumen tubing set for collection and anticoagulation of shed blood in surgery or trauma. The large tubing is used for aspiration of the shed blood. The small tubing welded to the large tubing provides anticoagulation. The large suction tube and small anticoagulation tube meet at the Yankauer adapter, to provide anticoagulation immediately after collection of blood. The suction line is connected to the appropriate collection reservoir by a ¼´´ female connector. The anticoagulant line is spiked to a anticoagulant container. Anticoagulant dosage is controlled by a roller clamp and regulates the drip rate of the anticoagulant into the drip chamber. The Yankauer adapter is designed to adapt to suction tips from 6.5 to 9.5 mm outer diameters.
{1}------------------------------------------------
The ATY Y-Adapter is a disposable tubing set used to connect two autotransfusion reservoirs to an autotransfusion disposable set prior to processing. Each branch of the Y-Adapter may be attached to the blood outlet port of two reservoirs by 2 stepped ¼´´ adapters. Each branch connecting to the reservoirs has a pinch clamp to control flow to the autotransfusion device. The Y-Adapter outlet line has a universal adapter fitting for ¼´ male connectors or 3/8´´ female connectors. Alternatively, the ATY Y-Adapter can be used to connect one autotransfusion reservoir and one oxygenator line to an autotransfusion device.
The ATO oxygenator line is a disposable tubing set for the collection or transfer of shed blood from the extracorporeal circulation (ECC) in cardiac surgery to an autotransfusion reservoir or to an autotransfusion device prior to processing. The is connected to the coronary perfusion port of an oxygenator prior to priming ECC. After conclusion of ECC, it may be connected to the free branch of a Y-adapter attached to an autotransfusion reservoir outlet, or directly to the blood inlet line of an autotransfusion device for direct processing. Alternatively it may be connected to a ¼" inlet connector of an autotransfusion reservoir to empty the oxygenator content into the reservoir prior to processing.
All three devices are for single patient use, sterilized using ethylene oxide gas, and the fluid paths are non-pyrogenic.
## Technological Characteristics of the Subject Device Compared with Predicate Devices
The 510(k) "Substantial Equivalence Decision Making Process (Detailed)" decision tree (ODE Guidance Memo #K86-3) was used to make a determination of substantial equivalence (reference Exhibit IV-1 included in this section). The answers to questions identified on this decision tree lead to a determination of substantial equivalence.
#### 1.0 Does the New Device Have the Same Indication Statements?
Yes. The Fresenius C.A.T.S Autotransfusion Accessories and Dideco-Shiley Autotransfusion Accessories are devices to be used during autotransfusion procedures to
- . aspirate, transfer, and anticoagulate blood from the surgical field to reservoir (Suctions Line); and
- . connect and transfer blood between reservoirs and/or oxygenators to an autotransfusion device (Y-Adapter) ; and
- connect and transfer blood between an oxygenator and/or reservoir to an autotransfusion . device, with or without a Y-Adapter (Oxygonator Linc).
#### 2.0 Does the New Device Have Same Technological Characteristics (e.g., design, materials etc.)?
Yes. All three devices have the same technological design. All of the devices are manufactured from polyvinyl chloride (PVC) tubing, of varying diameters, with appropriate connectors for their intended uses.
{2}------------------------------------------------
#### 3.0 Are the Descriptive Characteristics Precise Enough to Ensure Equivalence?
As the technological design, essential dimensions, materials, and manufacturing Yes. processes of the devices are comparable, comparative performance data between the Fresenius and Dideco-Shiley devices is not needed to demonstrate substantial equivalence. Biocompatibility studies, including cytotoxicity, sensitization, intracutaneous and systemic toxicity, hemocompatibility (hemolysis), genotoxicity, and pyrogenicity testing were performed to demonstrate the compliance of the Fresenius devices with applicable standards. Structural integrity testing on aged sterilized devices was also performed to demonstrate that the Fresenius devices could withstand twice the flow capacity and negative/positive pressures associated with use of autotransfusion devices. Shelf-life studies, including seal strength and dye leakage testing, demonstrated that the packaging systems are adequate to protect the devices and maintain sterility throughout the indicated one-year shelf-life.
#### 4.0 Does Performance Data Demonstrate Equivalence?
Yes. Based on the results of the testing cited above, Fresenius has demonstrated that:
- . The Fresenius C.A.T.S Autotransfusion Accessories satisfy requirements of the AAMI/ANSI standards for autotransfusion devices with respect to structural integrity and the materials used to manufacture the disposable sets and are suitable for the intended use of the device,
- . Shelf-life validation studies pertinent to the Fresenius C.A.T.S Autotransfusion Accessories have determined that the biocompatibility, structural integrity, packaging integrity and sterility of the Fresenius C.A.T.S Autotransfusion Accessories will be maintained for the labeled shelf-life,

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.
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.
