The MiRCSP cannula is intended for use during cardiopulmonary bypass for the delivery of cardioplegia retrograde through the coronary sinus for up to six hours. It is indicated for use during cardiac surgery for median sternotomy or minimally invasive (mini-sternotomy or right thoracotomy) access using direct, echocardiographic or fluoroscopic visualization techniques.
Device Story
MiRCSP Cannulae are single-use, sterile, nonpyrogenic devices for retrograde cardioplegia delivery during cardiopulmonary bypass (up to 6 hours). Device features manual or auto-inflating cuffs for coronary sinus occlusion and pressure measurement. A removable, malleable stylet provides stiffness and shape; it enables distal tip deflection and rotation to facilitate placement during minimally invasive procedures (mini-sternotomy, right thoracotomy). Cannulae are visible via ultrasound (TEE) and fluoroscopy to verify placement. Used by surgeons in OR settings. Output is the delivery of cardioplegia to the heart; visualization aids assist the surgeon in accurate positioning, reducing procedural difficulty in small-incision surgeries.
Clinical Evidence
Bench and animal testing only. No clinical data required. Testing included flow rate versus pressure drop, structural integrity of bonded joints and introducer, biocompatibility, and verification of visibility under ultrasound and fluoroscopic techniques.
Technological Characteristics
Single-use, sterile, nonpyrogenic retrograde cardioplegia cannula. Features manual or auto-inflating cuffs. Includes a removable, malleable stylet for shape/stiffness and distal tip deflection/rotation. Materials are consistent with predicate Medtronic devices. Designed for use with direct, echocardiographic, or fluoroscopic visualization.
Indications for Use
Indicated for patients undergoing cardiac surgery requiring cardiopulmonary bypass, including median sternotomy or minimally invasive access (mini-sternotomy or right thoracotomy), for retrograde cardioplegia delivery via the coronary sinus for up to six hours.

#### Device Description
MiRCSP Cannulae are single-use, sterile, nonpyrogenic devices designed to deliver cardioplegia through the coronary sinus in a retrograde manner, for periods up to six hours during cardiopulmonary bypass surgery. These devices are available in models that feature manual and auto inflating cuffs, and contain an aid in verification of cannula placement. The removable malleable stylet is used to provide stiffness and shape to the cannula body during insertion and features additional deflectability and rotation at the distal cannula tip to aid in placement into the coronary sinus. These cannulae have features that make them easier to use when minimally invasive surgical approaches are utilized (i.e., mini-sternotomy and right thorocotomy).

#### Indications for Use
The MiRCSP cannula is intended for use during cardiopulmonary bypass for the delivery of cardioplegia retrograde through the coronary sinus for up to six hours. It is indicated for use during cardiac surgery for median sternotomy or minimally invasive (mini-sternotomy or right thoracotomy) access using direct, echocardiographic or fluoroscopic visualization techniques.
#### Comparison to Predicate Devices
MiRCSP Cannulae contain the same technological characteristics when compared to the existing Medtronic (MDT) retrograde cardioplegia delivery cannulae utilize the design features and materials of the Medtronic RCSP Models 94113 and 94533, including a removable stylet introducer with a malleable shaft to provide cannula shape and stiffness. The MiRCSP introducer features additional distal tip deflectability and rotation to further aid in cannula placement when used in conjunction with small incision surgical approaches (i.e. thoracotomies or mini-sternotomies). The cannulae bodies include enhanced visibility in-vivo.
- Intended Use: The MiRCSP Cannula has the same intended use as the Medtronic DLP . Retrograde Coronary Sinus Perfusion Cannula with Manual-Inflating Cuff and Silicone Body, and DLP PVC Retrograde Coronary Sinus Perfusion Cannula with Auto-Inflate Cuff; with the addition of information regarding visibility and surgical procedure access.
- Principles of Operation and Technology: .
- MiRCSP Cannulae use the same technologies in operation as currently marketed o manual and auto-inflating retrograde coronary sinus perfusion cannulae.
- Temporary coronary sinus occlusion for delivery of retrograde cardioplegia and o measurement of coronary sinus pressure are accomplished in the same manner.
- MiRCSP Cannulae are also made from the same base materials as their MDT o predicates.
- Cannula introduction is accomplished in the same manner using a removeable, o malleable stylet, fully contained within the cannula body,
- The MiRCSP Cannula introducer also features the additional ability to deflect and o rotate the distal portion of the cannula, in-vivo, to further aid in placement of the cannula into the coronary sinus. This uses similar technology as the RMI Steerable Retrograde Cannula.
{2}------------------------------------------------
- MiRCSP Cannulae are visible under ultrasound (TEE) and feature enhanced o visibility under fluoroscopy in the distal tip area, to aid in placement verification, These features are also available with the Heartport Endocoronary Sinus Catheters.
- Performance: The MiRCSP Cannulae Models 94113TD, 94113TDT, 94533TD and ● 94533TDT were compared to previously cleared Medtronic RCSP Model 94113 and 94533, respectively, as predicates for performance characteristics. The comparisons demonstrated that these cannulae were substantially equivalent in performance.
#### Summary of Performance Data
Bench and animal testing were used to establish the performance characteristics of the modifications of this device from previously marketed MDT cannula devices. Clinical testing was not required to establish substantial equivalence. The following performance tests were conducted:
- Flow Rate Versus Pressure Drop �
- . Visibility Under Ultrasound and Fluoroscopic Visualization Techniques
- Structural Integrity (bonded joints and introducer) t
- Biocompatibility Testing .
#### Conclusion
Medtronic has demonstrated that the MiRCSP Cannula is substantially equivalent to the predicate devices based upon design, test results, and indications for use. Any noted differences do not raise new issues of safety and effectiveness.

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.
