#### Substantial Equivalence: 9.
The intended use and principal technological characteristics of the DEVICE are substantially equivalent to the legally marketed predicate device listed below:
> Medefil, Inc. Heparin I. V. Flush Syringe (K020996)
#### 10. Device Description:
ﺮ
The Heparin I. V. Flush Syringe (the DEVICE) is a single dose, disposable, sterile, plastic prefilled syringe. The DEVICE consists of a hypodermic syringe barrel, stopper plunger, plunger rod, luer lock (LL) tip cap and Heparin Lock Flush Solution, USP (1 Unit/mL or 10 Units/mL or 100 Units/mL in 0.9% Sodium Chloride), which meets the requirements set forth in the current USP Heparin Lock Flush Solution monograph. Two different sizes (6 mL, 12 mL) of hypodermic syringes will be utilized in packaging. The DEVICE will be marketed in the following dosage forms:
1 mL fill in 6 mL Syringe LL 2 mL fill in 6 mL Syringe LL 2.5 ml fill in 6 ml Syringe LL 3 mL fill in 6 mL Syringe LL 3 mL fill in 12 mL Syringe LL 5 mL fill in 6 mL Syringe LL 5 mL fill in 12 mL Syringe LL 10 mL fill in 12 mL Syringe LL
The hypodermic syringe is transparent. The barrel of the reservoir for the product and will be overfilled during manufacturing process. The plunger and plunger rod are the only two moving parts of the device. The flush solution is delivered by pressing down on the plunger rod, resulting in the expulsion of the fluid from the luer tip.
The DEVICE will be filled using fully automated syringe filling machine utilizing non - sterile components. The components of the DEVICE (hypodermic syringe, tip cap and (Heparin Lock Flush Solution, USP) will be sterilized using steam in a terminal sterilizer after the syringe barrel is filled with Heparin Lock Flush Solution and sealed with Tip Cap and Plunger Stopper.

#### 11. Intended Use:
Same Intended Use as the Predicate Device.
## For use to maintain the patency of in-dwelling intravenous vascular access device (IVAD).
- 12. Packaging:
The DEVICE provided is individually packaged in a plastic pouch (dust cover). There are thirty (30), sixty (60) or one hundred twenty (120) individually packaged DEVICES in a dispensing box. Nine hundred sixty syringes (thirty two boxes of 30's, or sixteen boxes of 60's or eight boxes of 120's) individually packed devices will be packed in a card board master carton.
The DEVICE shall be pyrogen free per the LAL test method for bacterial endotoxin.
- 13. Technological Characters:
The Medefil's Heparin I. V. Flush Syringe Device is similar to the legally marketed predicate device except the differences are:
- The DEVICE will be manufactured using terminal sterilization process using steam where as the a) predicate device was manufactured using aseptic technique. The DEVICE will be filled and sealed in syringe barrels and then it will be subjected to steam sterilization where as for the predicate device sterile solution was filled in pre sterilized syringe barrels and this leads to increased sterility assurance
- moreased blommy assulanter, the polypropylene used in the DEVICE was changed to one b) which will be able to withstand steam sterilization where as the polypropylene used in the predicate device was only able to withstand Gamma Radiation.
- Performance Data: 14.
Three types of tests - physical (dimensional), mechanical, and compatibility tests - were conducted. The dimensional and mechanical tests were conducted to demonstrate that the DEVICE meets the requirements set forth in the engineering drawings and that it performed comparably to the substantially equivalent device, thereby not affecting safety or effectiveness. These tests are done to assure the integrity of the container closure system. The terminally sterilized Heparin I. V. Flush Syringes were put through seal integrity tests (dye ingress test and microbial ingress test). The syringes tested were filled with product, sealed, steam sterilized using steam - air mixture (SAM) process, inspected, labeled and packaged for dye leak testing. The microbial ingress testing was performed by filling with Tryptic Soy Broth and tested for microbial ingress using vacuum method.

"Continuous improvement today for the challenges of tomorrow"
The polypropylene resin as well as various color tip caps in the DEVICE is intended for components destined for subsequent steam sterilization. The polypropylene was tested for Biological Reactivity Tests In Vitro and In Vivo. The polypropylene was found to meet the requirements of a USP Class VI plastic. Similarly polypropylene and tip caps are also not cytotoxic in nature.
The stability testing was performed on Heparin I. V. Flush Syringes after terminal sterilization, per USP monograph Heparin Lock Flush Solution, both at accelerated temperature and real time temperature to demonstrate that the new syringe material and the sterilization process is compatible with the USP Heparin Lock Flush Solution thereby supporting the claim that the change in fluid container material does not raise new types of safety and effectiveness questions
- Clinical Data: 15.
Heparin I. V. Flush Syringe, 100 Units/mL did not result in any hemloysis as measured by quantitating free hemoglobin in plasma and LDH levels. Also there was no change in osmolality. The study showed that dilution of heparin in whole blood did not result in any measurable changes in various markers of hemolysis.
- 16. Conclusion:
The DEVICE is safe and effective. The new characteristic does not affect safety and effectiveness of the DEVICE and the DEVICE is substantially equivalent to its legally marketed predicate device. The changes (change in polypropylene and terminal sterilization) do not affect the safety or effectiveness because the systems and processes have been validated and verified to yield a product that fits its intended use. The terminal sterilization process has decreased any risk for contamination as the sterile processes are enhanced. Biocompatibility of polypropylene is not a concern because it has been tested and it meets the requirements of USP Class VI plastic. The tests also show that the DEVICE is safe and effective, the new characteristics DO NOT adversely affect the safety and effectiveness of the DEVICE, and the DEVICE is substantially equivalent to its legally marketed predicate device.
- 17. Certification:
I certify that, in my capacity as President & CEO of Medefil, Inc., I believe to the best of my knowledge that all data and information submitted in the premarket notification are truthful and accurate and that no material fact has been omitted.
Sincerely

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.
