The RX NC Takeru PTCA Balloon Dilatation Catheter is indicated for balloon dilatation of the stenotic portion in the coronary artery or bypass graft stenosis for the purpose of myocardial perfusion. This product is also indicated for the post-delivery expansion of balloon expandable stents.
Device Story
RX NC Takeru is a rapid exchange PTCA balloon dilatation catheter used by interventional cardiologists in a catheterization lab. The device consists of a distal tube, guidewire transition tube, balloon, radiopaque markers, mid/proximal tubes, core wire, hub, and strain relief. The physician inserts a 0.014-inch guidewire through the catheter lumen to the target lesion. An external inflation device connected to the hub delivers pressurized inflation medium to expand the balloon, dilating the stenotic vessel or expanding a stent. The device facilitates myocardial perfusion by restoring blood flow. It is compatible with 5 or 6 Fr guiding catheters. The catheter is provided sterile for single use.
Clinical Evidence
Bench testing only. No clinical data. Performance evaluated via dimensional verification, balloon fatigue, burst pressure, compliance, inflation/deflation time, bond strength, flexibility, kink, torque, radiopacity, coating integrity, and particulate evaluation. Biocompatibility testing (ISO 10993-1) leveraged from reference device.
Technological Characteristics
Rapid exchange PTCA catheter; 1450 mm working length; 2.0-5.0 mm balloon diameters; 6-30 mm working lengths. Materials include hydrophilic coating. Sterilization via Ethylene oxide. Compatible with 0.014" guidewires and 5/6 Fr guiding catheters. Operates via hydraulic pressurization.
Indications for Use
Indicated for patients requiring balloon dilatation of stenotic coronary arteries or bypass grafts to improve myocardial perfusion, and for post-delivery expansion of balloon-expandable stents.
Regulatory Classification
Identification
Standard PTCA Catheter: A PTCA catheter is a device that operates on the principle of hydraulic pressurization applied through an inflatable balloon attached to the distal end. A PTCA balloon catheter has a single or double lumen shaft. The catheter features a balloon of appropriate compliance for the clinical application, constructed from a polymer. The balloon is designed to uniformly expand to a specified diameter and length at a specific pressure as labeled, with well characterized rates of inflation and deflation and a defined burst pressure. The device generally features a type of radiographic marker to facilitate fluoroscopic visualization of the balloon during use. A PTCA catheter is intended for balloon dilatation of a hemodynamically significant coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion. A PTCA catheter may also be intended for the treatment of acute myocardial infarction; treatment of in-stent restenosis (ISR) and/or post-deployment stent expansion. Cutting/scoring PTCA Catheter: A cutting/scoring PTCA catheter is a balloon-tipped catheter with cutting/scoring elements attached, which is used in those circumstances where a high pressure balloon resistant lesion is encountered. A cutting/scoring PTCA catheter is intended for the treatment of hemodynamically significant coronary artery stenosis for the purpose of improving myocardial perfusion. A cutting/scoring PTCA catheter may also be indicated for use in complex type C lesions or for the treatment of in-stent restenosis.

## Device Description:
RX NC Takeru PTCA Balloon Dilatation Catheter (RX NC Takeru) is a rapid exchange type of balloon dilation catheter, which consists of a distal tube, guidewire transition tube, balloon, radiopaque markers, mid tube, proximal tube, core wire, hub, and strain relief. A balloon is attached to the distal end of the catheter, and it can be inflated and deflated using the inflation device connected to the hub at the proximal end. RX NC Takeru has a guidewire lumen at the distal end of the catheter through which a guidewire can be inserted, and also an opening along the guidewire transition tube to the guidewire port for the exit of a guidewire.
The maximum compatible diameter of a guidewire used together with RX NC Takeru in a PTCA procedure is 0.014 inches. Additionally, guiding catheters with a diameter of 5 or 6 Fr have been deemed to be compatible with RX NC Takeru. The nominal inflated balloon diameters range from 2.0 mm to 5.0 mm with balloon working lengths of 6 mm to 30 mm. The catheter working length is 1450 mm.
{5}------------------------------------------------
## Indications for Use
The RX NC Takeru PTCA Balloon Dilatation Catheter is indicated for balloon dilatation of the stenotic portion in the coronary artery or bypass graft stenosis for the purpose of myocardial perfusion.
This product is also indicated for the post-delivery expansion of balloon expandable stents.
## Comparison of Indications for Use to Predicate Device
The RX NC Takeru has the same intended use (percutaneous transluminal coronary angioplasty) as the NC Quantum Apex. The indications for use of the RX NC Takeru is similar to those of the NC Quantum Apex. T Therefore, the subject device, RX NC Takeru, may be considered substantially equivalent to the predicate device.
## Comparison of Technological Characteristics to Predicate Device
Percutaneous Transluminal Coronary Angioplasty (PTCA) is the technological principle for both RX NC Takeru and the predicate device. PTCA is based on the use of Percutaneous Coronary Intervention (PCI) devices for the purpose of myocardial perfusion.
The RX NC Takeru and predicate device have following same technological elements:
- Operating principle balloon dilatation of stenotic portion by pressurization of . inflation medium
- . Fundamental catheter design - balloon, shaft, radiopaque marker, hub, hydrophilic coating
- Shaft type - rapid exchange
- Concomitantly used devices guidewire, guiding catheter, inflation device ●
- . Sterilization - Ethylene oxide
There are following minor technological differences between RX NC Takeru and predicate device:
- Combination of balloon diameter and balloon length .
- Shaft diameters
- Catheter effective length
- . Nominal Pressure and Rated Burst Pressure of certain balloon sizes
## Performance Testing
To demonstrate substantial equivalence of RX NC Takeru to the predicate device, the technological characteristics and performance criteria were evaluated using the bench testing recommendations outlined in the FDA Guidance Document "Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA)
{6}------------------------------------------------
Catheters" dated September 8, 2010. The following in vitro tests were performed on the subject device:
Dimensional Verification, Balloon Preparation, Deployment and Retraction, Balloon Rated Burst Pressure, Balloon Fatigue (Repeat Balloon Inflations), Balloon Compliance, Balloon Inflation and Deflation Time, Catheter Bond Strength, Flexibility and Kink Test, Torque Strength, Radiopacity, Coating Integrity, Particulate Evaluation, Balloon Rated Burst Pressure (in Stent), and Balloon Fatigue (Repeat Balloon Inflations; in Stent), Transportation and Shelf Life Testing.
The results from these tests demonstrate that the technological characteristics and performance criteria of the RX NC Takeru are adequate for the intended use of the device and that the device can perform in a manner equivalent to devices currently on the market with the same intended use.
## Biocompatibility:
To demonstrate the biological safety of the body-contacting materials and substantial equivalence of the RX NC Takeru to the predicate device, the following biocompatibility testing, which was performed on the reference device (RX Takeru) in accordance with "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process"; Guidance for Industry and Food and Drug Administration Staff" (dated June 16, 2016), was leveraged:
Cytotoxicity, Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Pyrogen, Hemocompatibility (in vivo thromboresistance, hemolysis, and complement), and Genotoxicity (mouse lymphoma, bacterial reverse mutation and in vivo cytogenetics assay)
The results from these tests demonstrate that the RX NC Takeru is biocompatible for its intended use similar to the predicate device.
## Conclusions:
The RX NC Takeru met all the predetermined acceptance criteria of design verification and validation as specified by applicable standards, guidance, test protocols and/or customer inputs. The RX NC Takeru PTCA Balloon Dilatation Catheter is substantially equivalent to legally marketed predicate devices.

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.
