#### Predicate Devices:
The modified PROTEUS™ Percutaneous Transluminal Angioplasty (PTA) Balloon Catheter with Embolic Capture Feature is claimed to be substantially equivalent to the following legally marketed predicate device:
- Angioslide PROTEUS™ PTA Balloon Catheter with Embolic Capture Feature . (K120805)
Performance Standards: There are no mandatory performance standards for this device.
Device Description (see Figure 1)
Image /page/1/Figure/7 description: This image shows a technical drawing of a medical device with various labeled components. The device includes a handle labeled as "3", a connector labeled as "2", and a tip labeled as "5". There are also detail views labeled "Detail A" and "Detail B" showing different configurations of the device's tip, with components labeled as "6", "7", "8", and "9".
Figure I
The Angioslide PROTEUS™ Percutaneous Transluminal Angioplasty (PTA) Balloon Catheter with Embolic Capture Feature is an over the wire dual lumen catheter with a foldable balloon (S) located near the distal atraumatic soft tip (9).
One lumen is used for inflation of the balloon and is accessed via the inflation port (2). The other lumen, starting at the guidewire port (10), allows access to the distal tip for guidewire insertion (max. 0.035"). The balloon has two radiopaque markers (8) for positioning the balloon relative to stenosis. The radiopaque markers indicate the dilating section of the balloon and help in balloon placement. The balloon is designed to provide an inflatable segment of known diameter and length at specified pressure.
{2}------------------------------------------------
The shaft (4) comprises the outer shaft (6) and the inner shaft (7). The distal end of the balloon (A) is connected to the inner shaft and the proximal end of the balloon (B) is connected to the outer shaft. The inner shaft is connected to the proximal hub (10) which is connected to the pulling knob (1) and the outer shaft is connected to the handle grip (3). The pulling knob lock ( 1 ) locks the handle grip and the pulling knob together. The distal end of the balloon is folded inwards towards the proximal end of the balloon, by pressing on pulling knob lock (11) and pulling the pulling knob away from the handle (1). The inward-folding of the balloon forms a cavity and allows for collection and removal of embolic material.
The balloon size and diameter are printed on the strain relief (12). Refer also to the package label for information about catheter length, balloon nominal and rated burst pressure, balloon size, balloon compliance, guidewire compatibility and sheath compatibility.
#### Indications for Use:
The PROTEUS™ Percutaneous Transluminal Angioplasty (PTA) Balloon Catheter with Embolic Capture Feature is indicated for peripheral transluminal angioplasty and for capture and removal of embolic material (e.g. debris, thrombus) during angioplasty, for the femoral, iliac. ilio-femoral, popliteal, tibial, peroneal, and profunda arteries.
The PROTEUS™ PTA Balloon Catheter with Embolic Capture Feature is not intended for use in the renal, cerebral, coronary or carotid vasculature.
#### Comparison of Modified Indications for Use
The modified indications for use clarifies the device functionality of the PROTEUSTM Percutaneous Transluminal Angioplasty (PTA) Balloon Catheter with Embolic Capture Feature. The modification of the phrase "capture and containment" to "capture and removal" in the Indications for Use is intended only to clarify the device's functionality and to accurately convey that functionality to the user. The technology of the device not only captures the embolic material in a closed cavity, but also provides corresponding removal after angioplasty of peripheral vasculature. There is no option for the containment of embolic material without its immediate subsequent removal.
The modified indications for use also serves to clarify the types of embolic material that the device is capable of capturing and removing, i.e. debris and thrombus. The clinical study (MC-LEADER) supporting the device`s original clearance in K090364 provides evidence of the embolic material (debris and thrombus) that the device successfully and effectively captured and removed from the subject`s peripheral vasculature.
The modified indications for use statement for the PROTEUS™ PTA Balloon Catheter with Embolic Capture Feature does not raise any new issues of safety and effectiveness as demonstrated through the risk analysis process as compared to the predicate device PROTUES™ PTA Balloon Catheter (K120805).
The unmodified PROTEUS™ PTA Balloon Catheter (K120805) is also indicated for peripheral transluminal angioplasty and for capture and containment of embolic material during angioplasty. Therefore, the subject device, the PROTEUS™ PTA Balloon Catheter with Embolic Capture Feature, is substantially equivalent to the predicate device.
{3}------------------------------------------------
#### Comparison of Technological Characteristics
The modified PROTEUS™ Percutaneous Transluminal Angioplasty (PTA) Balloon Catheter is an over the wire co-axial dual lumen catheter with a foldable balloon located near the distal atraumatic soft tip. The catheter is compatible with a 0.014" (3x100mm only) and 0.035" guide wire.
The balloon catheter technological characteristics of the modified PROTEUS™ PTA Balloon Catheter are identical to those of the unmodified PROTEUS™ PTA Balloon Catheter (K120805). In both devices, lesion dilation is achieved by means of an inflatable balloon.
The modified PROTEUSTM PTA Balloon Catheter overall length, catheter sheath sizing, balloon diameter, balloon length, balloon nominal pressure, balloon rated burst pressure and end hole diameter are the same as those of the unmodified PROTEUS™ PTA Balloon Catheter (K120805).
The embolic capture technological characteristics of the modified PROTEUSTM PTA Balloon Catheter are identical to those of the unmodified PROTEUS™ PTA Balloon Catheter (K120805). In both devices, the capture and removal of embolic material is achieved by proximal vessel occlusion, by means of an inflatable balloon, and subsequent aspiration of embolic material.
#### Summary of Additional Modifications
In addition to the modifications to the Indications for Use described above, Angioslide has also made the following additional modifications to the PROTEUS™ PTA Balloon Catheter with Embolic Capture Feature:
- · Corresponding to the addition of examples of embolic material (e.g. debris, thrombus) in the Indications for Use, the addition of the following warning: "The safety and efficacy of this device has not been evaluated for use in primary embolectomy or primary thrombectomy procedures."
- Removal of the stent-related contraindications for the device ("post-delivery dilation of . peripheral vascular stent" and "any vessel containing multiple overlapping stents")
- Miscellaneous labeling revisions ●
The additional modifications described above do not result in any substantial change to the device's intended use, fundamental scientific technology or principle of operation. Angioslide is not seeking a primary embolectomy or primary thrombectomy claim; therefore, the warning is a risk mitigation for the user mistakenly assuming the device can be used for primary embolectomy and primary thrombectomy based on the examples of embolic material provided in the modified Indications for Use statement. The stent-related contraindications are being removed based on successful design verification and validation demonstrating the device to perform safely and effectively in a stent environment.
The miscellaneous labeling revisions are minor revisions for clarity and, based on regulatory analyses, do not require a new 510(k) submission. However, the minor labeling changes are described in this submission for completeness.
{4}------------------------------------------------
#### Summary of Non-Clinical Testing
In viro bench testing of the Angioslide PROTEUS™ PTA Balloon Catheter was conducted in accordance with Angioslide's Risk Analysis and all applicable FDA Guidance documents and ISO standards, including:
ISO 10555-1 - Sterile, Single Use Intravascular Catheters- Part 1: General Requirements
ISO 10555-4 - Sterile, Single Use Intravascular Catheters- Part 4: Balloon Dilatation Catheters
FDA Guidance - Non-Clinical Tests and Recommended Labeling for Intravascular Stents and Associated Delivery Systems, April 18, 2010
FDA Guidance - Coronary and Carotid Embolic Protection Devices - Premarket Notification [510(k)] Submissions, February 15, 2008
FDA Class II Special Controls Guidance - Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters, September 8, 2010
All bench testing, unless otherwise specified, was conducted using finished devices which were sterilized by the final validated sterilization process.
#### Design Verification and Validation:
In order to support the removal of the two contraindications, "post-delivery dilatation of peripheral vascular stents" and "any vessel containing multiple overlapping stents." the aforementioned international standards and FDA guidance documents were followed. Representative devices were chosen specifically based on the details of the change being evaluated, i.e. device performance within a stent environment. Due to the fact that the only change to be evaluated is device performance within a stent environment, individual stent length has no impact. Therefore, each test utilized multiple stents of equivalent diameter to simulate the worst case stent environment, which were selected based on the balloon diameter to be tested.
Sample sizes used for Design Verification and Validation testing were based on required confidence / reliability levels as a result of risk analysis performed for the PROTEUS™ PTA Balloon Catheter, or per recommendations within the FDA Guidance "Non-Clinical Tests and Recommended Labeling for Intravascular Stents and Associated Delivery Systems." Specifically, the number of samples utilized for each test depended on whether the data to be collected was variable data or attribute data in nature.

#### PROTEUS™ PTA Balloon Catheter Design Verification and Validation Summary Table
{6}------------------------------------------------
The effects of using the PROTEUS™ PTA Balloon Catheter within a stent environment were specifically evaluated during verification and validation. The results of the specified testing showed that use within a stent environment with multiple overlapping stents had no adverse impact on balloon performance or clinical use characteristics of the device. All simulated use testing showed equivalent results to the predicate product family used without stents and no performance issues were raised during this testing.
#### Comparative Capture Efficiency (CE) Testing:
To ensure compatibility of results, the testing approach was identical to that used to gather baseline data submitted in the original 510(k) for the PROTEUS™ PTA Balloon Catheter device family (K90364). The CE testing for the modified PROTEUS™ PTA Balloon Catheter was conducted with multiple overlapping stents in order to evaluate the device's embolic capture performance against the embolic capture performance of the unmodified PROTEUS™ PTA Balloon Catheters, which were previously tested without stents.
The 3x100mm balloon catheter was utilized to characterize the total capture performance of the Angioslide PROTEUS™ PTA Balloon Catheter within multiple overlapping stents. The overall CE test results were consistent with values seen for the previously tested device sizes without multiple overlapping stents. A review of the data in detail revealed no significant anomalies in the raw or analyzed data; and trends in performance based on differences in device size were as expected.
Specifically, prior testing described an overall trend for the Angioslide device of increasing CE as lesion size (length and diameter) increases. This trend is the result of the size of the embolic material capture cavity increasing with increasing balloon length. The combination of this factor and the fact that the Angioslide device does not require additional lesion crossings for deployment causes an increase in CE as device size increases, regardless of the decrease in device diameter. Although there was a slight increase in overall particulate generation for the 3x100mm post-dilatation, the overall capture efficiency remained equivalent. The increase in overall particulate generation was expected due to the addition of multiple overlapping stents within the post-dilatation testing. The consistency of overall capture efficiency with or without multiple overlapping stents was also an expected result due to the direct correlation of lesion length to CE within the Angioslide device.
#### Biocompatibility Testing:
Based on Risk Analysis no additional biocompatibility testing was required for the modifications described in this submission.
#### Sterilization:
There have been no changes to the sterilization process for the modified PROTEUS™ PTA Balloon Catheter from its predicate device. K120805; therefore, no sterilization was performed.
#### Packaging:
There have been no changes to the packaging materials or assembly for the modified PROTEUS™ PTA Balloon Catheter from its predicate device, K120805; therefore, no packaging validation was performed.
{7}------------------------------------------------
#### Shelf Life:
The shelf-life of the modified PROTEUS™ PTA Balloon Catheter is identical to the currently validated three (3) year shelf life for its predicate device, PROTEUS™ PTA Balloon Catheter (K120805). Therefore, no shelf-life validation or accelerated aging tested were performed.
#### Pyrogenicity:
There have been no changes to the modified PROTEUS™ PTA Balloon Catheter that would affect its validated non-pyrogenic characteristics; therefore, pyrogenicity testing was not required.

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).

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
