#### Predicate Devices
Avalon (Maquet) Elite Bi-Caval Dual Lumen Catheter (K081820) TandemHeart Venous Cannula (K133236)
#### Device Description
The TandemHeart Veno-Venous Cannula Set consists of two components: a 29 Fr. Dual lumen Veno-Venous Cannula and a 13 Fr. Introducer. The Introducer is designed to accept a standard 0.038 inch guidewire. The TandemHeart Veno-Venous Cannula Set is intended as a single patient, single use, sterile device.
{4}------------------------------------------------
Image /page/4/Figure/0 description: The image is a diagram of the TandemHeart Veno-Venous Cannula. The diagram labels the barbed connectors, clamp areas, insertion depth markers, and tantalum markers. The insertion depth markers are labeled with the numbers 44, 42, and 40. The cannula also has a wire-reinforced area.
The TandemHeart Veno-Venous Cannula (Figure 1) consists of two distinct lumens with a wire-reinforced cannula body. The inner lumen is located entirely within the outer lumen forming two concentric channels
The distal section (inner lumen/cannula) of the cannula body has six side holes near the distal tip opening. The proximal sections of each lumen are clear and not wire-reinforced to allow visualization of blood and to enable clamping to prevent blood flow during setup and removal of the cannula from the extracorporeal circulatory support equipment (see Figure 1). A non-vented barbed connector is affixed to both proximal ends (inner/distal and outer/proximal lumens) of the cannula and allow for connection of standard 3/8 inch blood circuit tubing for subsequent connection to extracorporeal circulatory support equipment. The cannula has printed insertion depth markings every 10 centimeters from 10 to 30 cm followed by every 2 centimeters for the remainder of the insert-able length, measured from the distal end. The cannula also has a suture wing that can be used for securing the cannula in place to the patient.
The introducer (Figure 2) consists of a tube with a hub. The introducer fits inside the inner lumen of the cannula during insertion of the cannula/introducer assembly. The introducer is used to advance the cannula over a guidewire and facilitate cannula placement within the target vessel. The introducer has a hub at its proximal end to manage introducer insertion and removal from the cannula. The hemostasis cap minimizes blood loss when the cannula/introducer assembly is inserted into the target vessel. The introducer body is constructed from radiopaque material for visualization under fluoroscopy.
Image /page/4/Figure/4 description: The image shows a medical device, specifically an introducer needle, which is used to insert catheters or other devices into the body. The introducer hub is located at the end of the needle, and the hemostasis cap is located near the hub. The needle is long and thin, with a sharp point at the end.

#### Intended Use
The TandemHeart Veno-Venous Cannula Set is intended for use as a single cannula for both venous drainage and reinfusion of blood via an internal jugular vein during extracorporeal life support procedures.
#### Comparison of Technological Characteristics
The TandemHeart Veno-Venous Cannula Set and the predicate Avalon (Maquet) Elite Bi-Caval Dual Lumen Catheter (K081820) are both wire-reinforced dual lumen venous cannula. Both kits include an introducer to facilitate placement using a guidewire and fluoroscopy. There are a number of technological differences: 1) the TandemHeart Veno-Venous Cannula Set contains an additional component located on the exterior proximal portion of the cannula: a suture wing to provide a means of securing the cannula to the patient; 2) the TandemHeart Veno-Venous cannula is co-axial whereas the Avalon Elite predicate is bi-caval; 3) the TandemHeart Veno-Venous Cannula has a 29 Fr outer diameter at the proximal end compared to 27 Fr for the comparable Avalon Elite; 4) the TandemHeart Veno-Venous Cannula is longer than the predicate with greater distance between inlet and outlet to reduce recirculation and to allow improved flexibility in positioning within the venous system; and 5) the TandemHeart Veno-Venous Cannula features a taper from the narrow distal, single lumen portion to the larger diameter, proximal, dual lumen portion that is designed to aid with insertion by gradually dilating the vessel.
#### Performance Data
Non-clinical performance testing was conducted to demonstrate substantial equivalence of flow characteristics between the TandemHeart Veno-Venous Cannula and the predicate, Medtronic Avalon Elite The performance testing included in-vitro system capacity testing and flow vs. pressure drop (HQ). This testing verified that despite the longer length of the TandemHeart Veno-Venous Cannula relative to the Avalon Elite Cannula, it was able to sustain flows comparable to the predicate.
Flexibility, strength, biocompatibility, in-vitro hemolysis, leak testing, sterilization, and shelf life of the TandemHeart Veno-Venous Cannula are addressed by comparison with both the Avalon elite and a second predicate, the TandemHeart Venous Cannula (K133236). Based on the performance test results and data from the predicate devices, the TandemHeart Veno-Venous Cannula was found to meet established design input requirements and thus to be substantially equivalent to the predicate Avalon Elite Dual Lumen Veno-Venous Cannula.

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.
