Indications for Use
Wartie® Wart Remover is intended for over-the-counter treatment of common warts and plantar warts to be used in adults and children 4 years of age and older.
Device Story
Wartie® Wart Remover is a portable, over-the-counter cryosurgical device for home use. It consists of a pressurized canister containing 50ml of dimethyl ether (DME) and a custom applicator unit. The user activates the aerosol to deliver the cryogen to a metal nose piece, which acts as a cold retraction vehicle. The device is applied directly to the wart; the metal tip transfers cold to the skin, freezing the wart tissue. This process damages the wart cells, causing the wart to blister and fall off or be discarded by the body. The device features a secured locking ring for mechanical safety and thermal safety precautions during activation. It is intended for self-administration by patients or caregivers to treat common and plantar warts, providing pen-pointed accuracy for freezing.
Clinical Evidence
No clinical data provided. Safety and efficacy supported by bench testing, including comparative biological tissue skin test models against predicate devices, and literature regarding cryosurgical treatment of verrucae plantaris.
Technological Characteristics
Portable cryosurgical system. Materials: PP cap, POM cone/ring, nickel-coated bronze nose piece, aluminum canister. Energy: Thermal energy removal via cryogen (DME). Dimensions: Handheld aerosol canister. Connectivity: None. Sterilization: Not specified. Software: None.
Indications for Use
Indicated for OTC treatment of common and plantar warts in adults and children aged 4 years and older.

Wartie® Wart Remover differs from the predicate devices in that the material of the cold retraction vehicle differs. While Wartner® Wart Removal System, Dr. Scholl's® Freeze Away TM Wart Remover and Histofreezer® Wart Removal System apply a cryogen to a sponge, and , Wart Freeze applies a polypropylene applicator; Wartie® Wart Remover applies the cryogen to a metal nose piece which allows efficient heat transfer to the skin.
This difference in technology has been evaluated in bench testing to determine the equivalence of the products, and market experience and other available devices show that the heat transfer via a metal core is a used and approved technology.
The method of freezing skin via a metal applicator allows for pen-pointed accuracy in freezing the skin.
As mentioned earlier, bench testing has shown the performance of Wartie® Wart Remover to be equivalent with abovementioned OTC technologies in terms of safety and efficacy, thereby supporting its OTC status.
While the technology employed by Wartie® Wart Remover differs from its predicates in that the product uses pure DME gas applied via a metal applicator, bench testing has shown equivalent performance for safety and efficacy on biological tissue. DME gas is also used by Wart Freeze but with a polypropylene applicator.
Note: The limitation of 4 years and older is an industry-wide limitation based on clinical data available for comparable products. The predicate device Wartner® Wart Removal System -K032271, as well as other OTC products have the same restriction. The clinical study carried out with Histofreezer® has shown the technology to be appropriate for pediatric patients (above the age of 4) , A bench study, further discussed in section 18, has furthermore shown compared Wartie® Wart Remover with its predicate as well as other available products such as Histofreezer®, showing that its performance is within the parameters of Histofreezer® and, thereby, also applicable for patients above the age of 4. The bench study showing that Warties Wart Remover's metal probe does not adhere to the skin (also shown in section 18), thereby showing that there are no additional risks, further support the appropriate limitation to pediatric patients above the age of 4.

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.
