#### DEVICE DESCRIPTION:
The product is an empty flexible container (bag) in plastic material, that is to be filled before use, intended for the administration of intravenous infusion solutions), and provided sterile. It is provided in two different configurations, with three tubes or one tube:
- bag with 3 tubes:
The empty bag is filled by connecting it to containers (generally glass bottles) filled with the solutions to be administered. The filling is done through the tube with the big bore connector where the non- re-opening clamp is located; this tube is closed with a screwed cap (air-tight closure). After filling, the bag is clamped by means of the non-re-opening clamp and closed with the sealing cap (screwed cap), to secure the contents prior to administration. To make the fluid outflow from the bag towards the patient, the bag is connected to an intravascular administration set via the access port (spike port). When the bag is filled, other drugs can be added using the second access port (injection port). The device is available in multiple containment volumes ranging from 250mL to 5000mL.
{4}------------------------------------------------
## - bag with 1 tube:
the bag is provided with one tube used both for the filling of the bag and the administration of the solution to the patient. The tube is closed with a screwed male Luer cap (air-tight closure). The filling is done by connecting the female Luer connector of the tube to the containers filled with the solutions to be administered. After filling, the bag is clamped by means of a pinch clamp and closed with the sealing cap (screwed cap), to secure the contents prior to administration. To make the fluid outflow from the bag towards the patient, the bag is connected to an intravascular administration line via the same female Luer connector. It is available in multiple containment volumes of 50mL, 100mL, and 250mL.
## INDICATIONS FOR USE:
The Empty EVA Bag is an empty container used for administration of solutions to the patients using an intravascular administration set. Medication transfer in and out of the container is done using aseptic technique.
## TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL E Q U I V A L E N C E:

The subject device and the predicate device have similar indications for use; the subject device is indicated for general fluids whereas the predicate device is indicated for TPN only: the Indications for Use (IFU) for the predicate device (TPN solution) are narrower in comparison to the proposed indications for use for the subject device (general intravenous solution).
This difference in the IFU between the subject and the predicate device is not critical since both the devices are empty containers made of Ethylene Vinyl Acetate (EVA) material intended for administration of solutions to patient using an intravascular administration set. EVA is a stable material generally used in the administration of IV solutions to patients in hospitals and pharmacies. Expanding the IFU from TPN to general use does not affect the safety and effectiveness of the device, as supported by Biocompatibility per ISO 10993-1, chemical and performance testing per ISO 15747:2018, and luer connection per ISO 80369-.
The materials used to manufacture the subject device are the same or similar to those used for the predicate device. The subject device includes additional materials in comparison to the predicate device; however, these differences do not raise new questions of safety and effectiveness as they have been assessed through biocompatibility testing.
The subject device with the 3-tube configuration has the same technological characteristics and design as the predicate device. The subject device also has a 1-tube configuration, where the filling of the bag and the administration of the solution to the patient are performed in the
{6}------------------------------------------------
same tube, this different design does not affect the basic design principle and usage of the subject device and does not raise additional safety and effectiveness issue compared to the predicate device.
## SUBSTANTIAL EQUIVALENCE DISCUSSION:
## DISCUSSION OF NONCLINICAL TESTS

The minor differences between the devices do not raise any new issues of safety or effectiveness.
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.
