Indications for Use
The MI DeTACH® is indicated for use for temporary or partial occlusion of blood vessels during cardiovascular surgical procedures.
Device Story
MI DeTACH is a vascular clamp system consisting of a detachable aortic clamp head and a delivery system (delivery device and quick release device). Used in cardiovascular surgery by surgeons to achieve temporary or partial vessel occlusion. The delivery device delivers, clamps, deploys, and retrieves the clamp head. The clamp head features a pivoting top jaw for parallel closure and soft polymer padded jaws with non-metallic DeBakey teeth to distribute force. A ratchet mechanism provides tactile feedback, while a clutch mechanism prevents excessive force application by disengaging the lever. Once clamped, the handle detaches, leaving the clamp in the body during the procedure. The delivery device is used for removal; the quick release device serves as a backup for unclamping and removal if the delivery device fails. The system benefits patients by providing controlled, atraumatic vessel occlusion during surgical procedures.
Clinical Evidence
No clinical data. Substantial equivalence supported by non-clinical bench testing, including vessel occlusion testing, clamping force distribution testing, human factors/usability studies, and simulated use testing. Biocompatibility testing was conducted per ISO 10993-1 (cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogen testing, and hemolysis). Sterilization, shelf-life, and fatigue testing were also performed.
Technological Characteristics
System includes detachable aortic clamp head (Small, Medium, Large) and delivery/quick-release devices. Features: non-metallic soft polymer DeBakey teeth, pivoting top jaw for parallel closure, ratchet-based tactile feedback, and clutch-based force-limiting mechanism. Clamp head provided sterile (2-year shelf life); delivery system provided non-sterile for facility cleaning/sterilization (100-cycle life). Biocompatibility per ISO 10993-1 for tissue contact <24 hours.
Indications for Use
Indicated for temporary or partial occlusion of blood vessels during cardiovascular surgical procedures in patients requiring such intervention.

#### III. PREDICATE DEVICE INFORMATION
MI DeTACH® is substantially equivalent in function and intended use to Flexline Clamp (now known as Cygnet® Flexible Clamp) (K010727) and the Cardio Vision® MICS Aortic Clamps (K123571).
### IV. INDICATIONS FOR USE
The MI DeTACH® is indicated for use for temporary or partial occlusion of blood vessels during cardiovascular surgical procedures.
#### V. DEVICE DESCRIPTION
The MI DeTACH® is comprised of a Detachable Aortic Clamp Head and a Delivery System. The MI DeTACH® Detachable Aortic Cross Clamp Head (Figure 10.6-1) is available in three sizes: Small, Medium, and Large (55mm, and 85mm enqagement pads respectively) which are packaged and distributed separately. The Delivery System is comprised of a Delivery Device (Figure 10.6-2) and Quick Release Device (Figure 10.6-3). The Delivery Device is used to deliver, clamp, deploy, unclamp, and retrieve the Clamp Head from the target occlusion site.
The MI DeTACH® Detachable Aortic Cross Clamp Head works by applying compression forces to the vessel by the padded device jaws. The top jaw is a pivot jaw allowing for parallel closure of the vessel during clamping. The amount of compression applied to the vessel for occlusion or partial occlusion is determined or adjusted by the means of the Delivery Device lever actuated jaw closure mechanism. The Clamp Head device contains ratchets that provide clamping tactile feedback to the user. A clutch mechanism prevents the user from applying excessive forces to the vessel by disengaging the lever from the device when specific force is obtained. Upon successfully clamping, the device locks and the handle is then detached leaving the clamp in the body throughout the duration of the procedure. The Delivery Device is then used to unclamp and remove the Clamp Head from the body upon procedure completion. In the event the Delivery Device becomes compromised during the course of a procedure, the Quick Release Device can be used to unclamp and remove the Clamp Head from the body.
#### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
MI DeTACH® and its predicates have the same intended use, clinical setting, target user, target patient population, and principle of operation.
The MI DeTACH® uses the same principle of operation and technology as predicate devices. It is based on utilizing two clamp jaws compressing a vessel to apply sufficient forces to occlude blood flow in the vessel. The subject and predicate devices are based on the same technological elements:
{5}------------------------------------------------
- Clamp delivered through a small incision with an external handle
- Handle controls clamping force through the means of a ratchet or lever ● mechanism at the handle
- . Soft polymer padded jaw to distribute clamping forces
- DeBakev Teeth lining the clamp to provide traction and distribute clamping forces . over a larger surface area
- Clamp is detached leaving clamp in the body throughout the procedure
The following technological differences exist between the subject and the predicate device:
- DeBakey teeth are made of soft polymer and are nonmetallic ●
- The top jaw pivots which allow parallel closure
- . Clutch safety mechanism prevents excessive clamping forces

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.
