Indications for Use
The BridgePoint Medical System (consisting of the CrossBoss™ Catheter, Stingray™ Orienting Balloon Catheter, and Stingray™ Guidewire) is intended to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions) prior to PTCA or stent intervention.
Device Story
BridgePoint Medical System comprises CrossBoss Catheter, Stingray Orienting Balloon Catheter, and Stingray Guidewire. Used in coronary/peripheral vasculature to facilitate guidewire placement beyond chronic total occlusions (CTO). CrossBoss catheter features coiled stainless steel shaft, hydrophilic coating, and torque device for manual manipulation; provides pushability and torque. Stingray balloon catheter features dual-lumen design with side-ports for guidewire steering and non-compliant balloon for fluoroscopic orientation. Stingray guidewire is 0.014" stainless steel with platinum/tungsten coil for radiopacity. Operated by physicians in clinical settings (e.g., cath lab) under fluoroscopic guidance. System enhances ability to navigate stenotic lesions; facilitates subsequent PTCA or stent placement. Benefits include successful guidewire crossing of complex lesions with reduced risk.
Clinical Evidence
Clinical evaluation included a 147-patient study in the United States. Study demonstrated the system successfully facilitates placement of guidewires beyond chronic total occlusions with no significant increase in patient risk. Bench testing (tensile, torque, kink resistance, trackability, corrosion, coating durability, particulate, balloon performance, dimensional) and biocompatibility testing were leveraged from identical predicate devices.
Indicated for patients requiring intraluminal guidewire placement beyond stenotic coronary lesions, including chronic total occlusions, prior to PTCA or stent intervention.

#### Device Description:
The CrossBoss Catheter is a single use over the wire disposable percutaneous catheter consisting of a full length coiled stainless steel shaft with polyester and polyurethane exterior. The coiled shaft provides torque and makes it possible to push the device, and also provides a guidewire lumen. The distal shaft transitions to an enlarged (1mm diameter) rounded distal tip. This stainless steel tip provides an atraumatic element that is intended to enhance the catheter's ability to move within the vasculature with reduced risk of arterial tissue engagement while providing radiopaque visibility. The distal portion of the CrossBoss Catheter is hydrophilic coated to enhance lubricity. The proximal portion includes an internal stainless steel hypotube stiffener that provides additional push. A torque device, coaxially positioned over the proximal portion of the CrossBoss Catheter, provides a comfortable user interface for device manipulation. The torque device (similar to a guidewire torque device) is positionable along the proximal portion of the catheter and includes a torsion release safety mechanism. This safety mechanism insures the torque input generated by the user remains within the torsional operating strength of the catheter shaft.
The Stingray Orienting Balloon Catheter is a single use, over-the-wire, disposable, dual lumen percutaneous catheter that facilitates the placement, support and steering of a guidewire into discrete regions of the coronary and peripheral vasculature through the central guidewire lumen or through one of two side-ports (identified by radiopaque markers). The side-ports connect with the central guidewire lumen and facilitate guidewire steering (at an angle to the central lumen) by allowing the guidewire to exit the catheter. The catheter contains a small non-compliant balloon segment used for fluoroscopic orientation on the distal tip of the flexible shaft.
The Stingray Guidewire is a conventionally constructed 0.014" diameter, single use, disposable guidewire that consists of a full-length stainless steel shaft with proximal PTFE coating where the distal portion of the shaft is taper ground to provide distal flexibility. The distal portion also includes a coaxially positioned coil constructed of platinum/tungsten material for visibility under fluoroscopy. The coil is fixed to the stainless steel core wire via silver alloy solder and is coated with hydrophilic coating. The distal tip of the guidewire is supplied with an angled geometry which transitions to a conventional rounded tip. The core wire (~0.0035" diameter) extends approximately 0.007" distal of the rounded tip.
#### Intended Use:
The BridgePoint Medical System (consisting of the CrossBoss™ Catheter, Stingray™ Orienting Balloon Catheter, and Stingray™ Guidewire) is intended to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions) prior to PTCA or stent intervention.
{2}------------------------------------------------
#### Comparison to Predicate Device(s):
The designs of the devices comprising the BridgePoint Medical System are identical to their respective predicate devices. Bench testing was previously conducted using the CrossBoss Catheter, Stingray Orienting Balloon Catheter, and Stingray Guidewire predicate devices in tests designed to address a chronic total occlusion application. Therefore, all prior bench performance testing (tensile, torque, kink resistance, trackability, corrosion, coating durability, particulate, balloon performance, dimensional, etc.) are directly applicable to this application. As well, all previous biocompatibility tests conducted for the aforementioned predicate devices is directly applicable to the devices that comprise the BridgePoint Medical System as they are identical.
As demonstrated in both animal studies and human clinical evaluations, the devices used as a system functions to enhance medical practice in facilitating the placement of guidewires or other interventional devices beyond chronic total occlusions. A 147 patient study was conducted in the United States that demonstrated the BridgePoint Medical System could successfully allow the placement of guidewires beyond chronic total occlusions with no significant increase in risk to the patient.
#### Summary:
Based upon the intended use and descriptive information provided in this pre-market notification. the BridgePoint Medical System consisting of the CrossBoss™ Catheter, Stingray™ Orienting Balloon Catheter, and Stingray™ Guidewire has been shown to be substantially equivalent to the 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.
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.
