The Weinmann Tracheostomy Exchange Set is intended for adult tracheostomy tube exchange.
Device Story
The Weinmann Tracheostomy Exchange Set facilitates the exchange of an existing tracheostomy tube in adult patients. The set includes a Ciaglia Blue Rhino Percutaneous Tracheostomy Dilator, five Ciaglia loading dilators, an 8-Fr airway exchange catheter, and two Rapi-Fit adapters. The airway exchange catheter is inserted into the existing tracheostomy tube to maintain airway patency during the procedure. The dilator is then advanced over the catheter to dilate the stoma for the new tube. Rapi-Fit adapters allow for oxygenation via 15-mm CPAP ventilator connections or high-pressure jet ventilation during the exchange. The device is intended for use by clinicians in a medical setting. By maintaining airway access throughout the exchange process, the device helps prevent airway collapse and facilitates safe tube replacement.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing, including dimensional and compatibility evaluations, and leveraged biocompatibility data from previously cleared predicate and reference devices.
Technological Characteristics
Materials include polyurethane. Components: 38-Fr dilator (20 cm, hydrophilic coating, depth markings), 21-28 Fr loading dilators, 8-Fr airway exchange catheter (45 cm), and Rapi-Fit adapters (15-mm and Luer lock). Sterilization via ethylene oxide. Device is for single-use. No software or electronic components.
Indications for Use
Indicated for adult patients requiring tracheostomy tube exchange.
Regulatory Classification
Identification
A tracheostomy tube and tube cuff is a device intended to be placed into a surgical opening of the trachea to facilitate ventilation to the lungs. The cuff may be a separate or integral part of the tracheostomy tube and is, when inflated, intended to establish a seal between the tracheal wall and the tracheostomy tube. The cuff is used to prevent the patient's aspiration of substances, such as blood or vomit, or to provide a means for positive-pressure ventilation of the patient. This device is made of either stainless steel or plastic.

### Predicate Device:
The Weinmann Tracheostomy Exchange Set is substantially equivalent to the predicate device, the Ciaglia Blue Rhino® Percutaneous Tracheostomy Introducer Sets (Cook Incorporated, K133597), cleared for market by FDA on April 18, 2014.
## Device Description:
The subject device, the Weinmann Tracheostomy Exchange Set, includes a Ciaglia Blue Rhino Percutaneous Tracheostomy Dilator (cleared under K133597), five Ciaglia loading dilators (21-, 24-, 26-, 27-, and 28-Fr; cleared under K133597), an 8-Fr Cook Airway Exchange Catheter (cleared under K162729), and two Rapi-Fit Adapters (cleared under K162729).
{4}------------------------------------------------
Image /page/4/Picture/0 description: The image shows the logo for Cook Medical. The logo consists of the word "COOK" in white, block letters on a red background. Below the word "COOK" is the word "MEDICAL" in white, block letters on a red background that is shaped like a banner.
The Ciaglia Blue Rhino Percutaneous Tracheostomy Dilator is designed to be advanced over an airway exchange catheter into an existing tracheostomy tube to dilate the stoma, to be prepared for replacement of a new tracheostomy tube. The dilator is 38.0-Fr in outer diameter and 20 centimeters long. This dilator has a depth marking to indicate the skin level, which is placed 11 centimeters from the distal tip. Another feature of the device is the presence of hydrophilic coating on the distal 11 centimeters of the device.
The Ciaglia loading dilators are designed to be inserted into a new tracheostomy tube to facilitate dilation of the stoma and placement of the tube in the airway. The dilators are available in outer diameter of 21 to 28 Fr; all dilators are 20 centimeters long and curved at the distal end.
The airway exchange catheter is designed to be inserted into the previously existing tracheostomy tube in patients prior to removal. The airway exchange catheter keeps the airway open during dilation and placement of a new tracheostomy tube. The airway exchange catheter is 8.0 Fr in outer diameter and 45 centimeters long. The distal end of the airway exchange is a blunt tip with rounded edges.
Two Rapi-Fit adapters (one with a 15-mm connector, and one with a Luer lock connector) are provided to be used with the airway exchange catheter for oxygenation when the requirement for oxygen is high in patients but the tracheostomy tube is not in place. The 15 mm Rapi-Fit adapter is designed for attachment to traditional ventilator sources that are low pressure sources, or so-called continuous positive airway pressure (CPAP) ventilators. The Luer Lock Rapi-Fit adapter is designed for attachment to a highpressure jet ventilation oxygen source. The Luer Lock connection is a male Luer Lock that is compatible with the standard Luer fitting of an oxygen tube which is connected to an oxygen source.
### Indication for Use:
The Weinmann Tracheostomy Set is intended for adult tracheostomy tube exchange.
### Comparison to Predicate:
The subject device is substantially equivalent to the predicate device in that they have the same intended use, which is to assist placement of a tracheostomy tube. Furthermore, they have similar indications for use, technological characteristics, method of operation,

The differences in Indication for Use and technological characteristics between the predicate and subject devices do not raise different questions of safety or effectiveness because:
- -Indication for Use: the predicate is used for the initial placement of a tracheostomy tube when no tracheostomy exists. The subject device is used to exchange an existing tracheostomy tube to a new one. Initial placement of the tracheostomy tube as in the predicate device indication requires creating a percutaneous opening into the patient's airway through the tracheal cartilages. This access procedure is not required for the subject device as there is already a tracheostomy tube in place. The exchange aspect of the subject device does not raise different questions of safety or effectiveness as comparing to the predicate.
- -Additional components: the exchange catheter and adapters included in the subject device set have been previously cleared under K162729.
## Technological Characteristics:
The subject device. Weinmann Tracheostomy Exchange Set, was subjected to applicable non-clinical testing to ensure reliable design and performance under the specified design requirements. Testing includes:
- . Dimensional and Compatibility Evaluation of the subject device (Accelerated/Real Time Aged).
- . Biocompatibility testing - Data from the Ciaglia Blue Rhino Percutaneous Tracheostomy Introducer Set/Tray cleared under K133597 and the Cook Airway Exchange Catheter cleared under K162729 were leveraged to mitigate biocompatibility testing. Test results indicate that all materials are biocompatible.
The results of these tests show that the subject device meets the design input requirements based on the intended use and support the conclusion that the subject device does not raise different questions of safety or effectiveness and is substantially equivalent to the predicate device.
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.
