Indications for Use
The TigerPaw® System is indicated for the occlusion of the left atrial appendage, under direct visualization, in conjunction with other open cardiac surgical procedures. Direct visualization, in this context, requires that the surgeon is able to see the heart directly, without assistance from a camera, endoscope, or any other viewing technology. This includes procedures performed by sternotomy (full or partial) as well as thoracotomy (single or multiple).
Device Story
TigerPaw System is an implantable fastener and delivery tool for left atrial appendage (LAA) occlusion during open cardiac surgery. The implant consists of linearly spaced connectors overmolded with soft silicone to conform to anatomy. The disposable delivery tool features a pistol-grip handle with triggers that actuate jaws to mate the fastener sides together. Used in OR by surgeons under direct visualization (no cameras/endoscopes). The device provides mechanical occlusion of the LAA, intended to reduce risk of thromboembolic events. Clinical benefit includes complete LAA closure confirmed by TEE, preventing leakage or communication between LAA and left atrium.
Clinical Evidence
Prospective clinical study of 60 patients undergoing open cardiac surgery. Primary safety endpoint: device-related adverse events (AEs) at 30 days. Primary effectiveness endpoint: complete LAA occlusion confirmed visually and via TEE at 90 days. Results: 100% (60/60) visual confirmation of occlusion; 100% (54/54) TEE confirmation at 90 days. Zero incidences of bleeding or leakage. One minor device-related tissue tear repaired with suture. No unanticipated AEs or late device-related AEs reported.
Technological Characteristics
Implantable fastener composed of linearly spaced connectors overmolded with soft silicone. Delivery tool is a hand-held, disposable, pistol-grip mechanical device. Sterile, single-patient use. No electronic components or software.
Indications for Use
Indicated for occlusion of the left atrial appendage (LAA) in patients undergoing open cardiac surgical procedures (e.g., valve repair/replacement, CABG, cardiac ablation). Requires direct visualization without endoscopic assistance.

#### Predicate Devices:
The TigerPaw System is substantially equivalent in intended use and method of operation to a combination of the following predicate devices:
| USGI Auto Suture TA & GIA Staplers | K032696 |
|---------------------------------------------------------------------|---------|
| Synovis Surgical Innovations, Peri-Strips Staple Line Reinforcement | K040415 |
#### Device Description:
The TigerPaw System consists of an implantable Fastener and Delivery Tool designed for occlusion of the left atrial appendage, under direct visualization, in conjunction with other open cardiac surgical procedures. The Fastener is composed of linearly spaced connectors overmolded with a soft silicone. The spacing between the connectors along with the silicone gives the Fastener an ability to conform to the anatomy and completely exclude the LAA. The TigerPaw® System also includes a hand-held disposable Delivery Tool. The Delivery Tool
{1}------------------------------------------------
consists of a pistol grip handle with triggers that when actuated close jaws that in turn mate the two sides of the permanently implanted Fastener together.
### Intended Use:
The TigerPaw® System is indicated for the occlusion of the left atrial appendage, under direct visualization, in conjunction with other open cardiac surgical procedures.
Direct visualization, in this context, requires that the surgeon is able to see the heart directly, without assistance from a camera, endoscope, or any other viewing technology. This includes procedures performed by sternotomy (full or partial) as well as thoracotomy (single or multiple).
#### Comparison to Predicate Device(s):
The design of the TigerPaw® System is similar to the USGI device in that they are devices designed to place titanium or stainless steel staples in various types of tissue. The TigerPaw® System is similar to the Synovis predicate in they both use a non-absorbable material to reinforce suture-lines and staple-lines. All devices are packaged sterile and are for single patient use. Further, the TigerPaw® System and the predicate devices have the same or similar intended use.
#### Device Evaluation:
Extensive bench, animal, and cadaver evaluations were performed on the TigerPaw System. This testing consisted of in vitro bench testing, including connector tensile testing and pressure leak testing of fasteners; in vivo animal evaluation composed of a total of six acute canine and six chronic canine survived for six months with corresponding histopathology; and in situ cadaver evaluation comprising 14 specimens with varying disease history including gross pathology. Finally, a 60 patient clinical study was conducted.
Clinical study: This study was conducted to assess the safety and effectiveness of surgical Left Atrial Appendage (LAA) occlusion, using the LAAx, Inc. TigerPaw System (delivery system and implant/Fastener), as a concomitant procedure to other open chest cardiac surgery procedures including valve repair / replacement, coronary artery bypass grafting (CABG), and cardiac ablation procedures. The primary safety outcome was the rate of device related adverse (AE) and serious adverse events (SAE) assessed peri-operatively, and at 30 days post procedure. The primary effectiveness outcome was the percentage of patients with complete occlusion of the LAA assessed peri-operatively, both visually (implant/Fastener applied fully across the LAA Os) and via Transesophageal Echocardiography (TEE), and at 90 days post procedure also using TEE. Secondary safety endpoints included Major Adverse Cardiac Event (MACE) rates. Secondary effectiveness endpoints included the assessment of the size of residual LAA cavity remaining after application of the TigerPaw® System compared with a pre-defined target (≤ 6 mm).
There were no unanticipated adverse events (AE) with one minor device-related tissue tear repaired with suture. Complete Left Atrial Appendage (LAA) occlusion was visually confirmed in each of the 60 treated patients and confirmed by Transesophageal Echocardiography (TEE) in 56 patients with one patient requiring adjunctive use of suture to achieve LAA closure. There were zero incidences of bleeding or leakage from the area of the device footprint. Fifty-four out
{2}------------------------------------------------
of 54 evaluable patients followed up at the final 90 day period were confirmed to have complete LAA occlusion via TEE with zero leaks or communication between the LAA and LA and no late device-related AEs.
## Summary:
Based upon the intended use, descriptive information, and the in vitro, in vivo, in situ, and clinical performance evaluation provided in this pre-market notification, the TigerPaw System has been shown to be substantially equivalent to currently marketed predicate devices.

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.
