Indications for Use
The EsoFLIP® ES-310 balloon catheter is indicated for use to dilate esophageal strictures due to esophageal surgery, primary gastro-esophageal reflux and radiation therapy. Note: The EsoFLIP® ES-310 balloon catheter is to be used only with the EndoFLIP® system.
Device Story
EsoFLIP® ES-310 is a balloon dilation catheter used by surgeons/gastroenterologists in hospitals/surgery centers. It functions exclusively with the EndoFLIP® system, which provides balloon inflation via a syringe driver and displays cross-sectional area (CSA) images. The catheter features 8 integrated sensors to measure balloon diameter at 8 points along its length during saline inflation. Clinicians use the real-time diameter/CSA feedback to monitor stricture dilation. The device benefits patients by providing a smaller balloon size (6-10mm range) for treating narrower strictures compared to previous models. It is a single-patient-use, disposable device.
Clinical Evidence
Bench testing only. Performance testing included balloon fatigue, compliance, burst testing, catheter assembly testing, and diameter measurement accuracy. Results demonstrated the device performed to specifications. Biocompatibility is identical to the predicate.
Indicated for patients requiring dilation of esophageal strictures due to surgery, primary gastro-esophageal reflux, or radiation therapy. Contraindicated if endoscopy is contraindicated, in patients with actively bleeding varices, or for strictures <6mm or >10mm.

#### Device Description:
The EsoFLIP® ES-310 catheter is a balloon dilation catheter. It is used by surgeons or gastroenterologists to dilate esophageal strictures due to esophageal surgery, primary gastroesophageal reflux, and radiation therapy. This indication for use is identical to the predicate EsoFLIP® ES-series (ES-320) predicate, K142000.
The EsoFLIP® catheter connects to the EndoFLIP® imaging system in the same fashion as the predicate EsoFLIP® catheter, to display an image of the cross-sectional-areas (CSAs) of the dilation balloon, and to allow the balloon to be inflated using the EndoFLIP® syringe driver.
In all cases the catheters are to only be used with the EndoFLIP® system.
#### Modifications of these devices vs. Predicates:
The following is a summary of the differences between the proposed EsoFLIP® ES-310 catheter and the predicate EsoFLIP® ES-series (ES-320) catheter, cleared under K142000.
- (1) Change of the balloon size for use in smaller strictures.
- a. This of course affects the working specifications of the balloon
- b. Measurement range, Reading Length, Working Length, Maximum Filling Volume
- (2) Has diameter measurements (Sensors) at 8 points vs. the ES-320 (K142000) at 16 points
- a. Other EndoFLIP® catheters have been cleared with 8 sensors (BF-325N -K130906)
{4}------------------------------------------------
- Maximum Balloon Inflation Pressure 1.5 ATM (3)
- a. The predicate ES-320 (K142000) has a Maximum Inflation Pressure of 2 ATM; however reference ES-330 (K132337) with similar indications has a maximum inflation pressure of 1.5 ATM.
The EsoFLIP® ES-310 balloon dilation catheter is used exclusively with the EndoFLIP® system. The user interface is unchanged.
#### Indications for Use:
The EsoFLIP® ES-310 balloon catheter is indicated for use to dilate esophageal strictures due to esophageal surgery, primary gastro-esophageal reflux and radiation therapy.
Note: The EsoFLIP® ES-310 catheter is to be used only with the EndoFLIP® system.
| Patient Population: | Patient population is patients with strictures |
|---------------------|------------------------------------------------|
| Environment of Use: | Hospitals and Surgery Centers |
#### Contraindications:
The EsoFLIP® ES dilation catheter is contraindicated where:
- (1) endoscopy is contraindicated,
- (2) with actively bleeding varices and
- (3) for diameter measurements and dilation of strictures smaller than 6mm or greater than 10mm
#### Predicate Device Comparison:
Table 1 compares the EsoFLIP® ES-310 catheter to the predicate Crospon EsoFLIP® ES-series (ES-320) (K142000) and the references.
The EsoFLIP® ES-310 dilation catheter is viewed as substantially equivalent to the predicate -Crospon EsoFLIP® ES -series (ES-320) cleared under K142000 because:
#### Indications -
The dilation indications for use are identical to the predicate K142000. Discussion - The indications for use for the proposed device does not change from the predicate Crospon EsoFLIP® ES-series, K142000.
#### Patient Population -
The patient populations are identical, specifically indicated for patients requiring dilation of esophageal strictures.
Discussion – The patient population is unchanged and identical to the predicate Crospon EsoFLIP® ES-series, K142000. However, the diameter of strictures that the ES-310 dilation catheter is intended to be used with is smaller (6 to 10 mm).
#### Environment of Use -
The environments of use - hospital and surgery centers - are identical to the predicate. Discussion - The environments of use are identical to the predicate Crospon EsoFLIP® ESseries. K142000.
{5}------------------------------------------------
### Contraindications -
The contraindication related to minimum and maximum diameters of strictures that the catheter may be used with has been updated to reflect the proposed ES-310's smaller balloon size. Discussion - The contraindications are identical with exception of the update of sizing to the predicate Crospon EsoFLIP® ES-series, K142000.
#### Technology -
The EsoFLIP® Des measurement technology, construction, and design are unchanged from the EsoFLIP® ES-series catheter, K142000, when used with the EndoFLIP® system as cleared under K160725.
Discussion - The diameter measurement technology is unchanged from the predicate. The proposed EsoFLIP® ES-310 catheter measures diameter at 8 points, whereas the predicate K142000 measures at 16 points. However, Crospon has clearance for catheters which measure at 8 points, namely BF-325N, K130906.
The dilation technology of the EsoFLIP® ES catheter: maximum diameter and balloon working length, is similar to the predicate Crospon ES-series (ES-320) K142000.
The maximum inflation pressure of 1.5 ATM is identical to that of the reference Crospon EsoFLIP® ES-330 (K132337). While different from the predicate, which has a maximum inflation pressure of 2 ATM, Crospon has clearance for a catheter with a 1.5 ATM maximum inflation pressure that has a similar intended use.
### Non-clinical Comparative Performance and Specifications -
#### Bench Testing -
The Performance Testing included -
- Balloon Fatigue testing
- Balloon Compliance testing ●
- Balloon Burst test
- . Catheter Assembly test
- Diameter measurement accuracy testing .
Other testing was leveraged from the predicate. The testing demonstrated that the proposed EsoFLIP® ES-310 Balloon Dilation Catheter performed to its specifications (dilation and measurement) and thus is substantially equivalent to the predicate devices.
#### Biocompatibility-
The materials in contact with the patient are identical to the predicate, EsoFLIP® ES-series (K142000).
Discussion - The materials are unchanged from the predicate.
#### Discussion of Differences
The differences between the proposed and predicate device relate to:
- Size of balloon ●
- This does not alter population or indications for use. It allows the clinician a o smaller size for use with their patients
- Contraindication ●
{6}------------------------------------------------
#### 510(k) Summary Page 4 of 6 20-Nov-17
- The change is only with the dimensions. Otherwise the contraindications are o identical
- Maximum inflation pressure
- Crospon has clearance for inflation at 1.5 ATM vs. the predicate at 2.0 ATM O
- . Number of Sensors
- o The subject device has 8 sensors. The K130906 BF-325N also has 8 sensors.
All of the differences have been cleared under previous 510(k) except the balloon size, which is only being offered for the clinician who requires a smaller size. These changes do not alter the indications for use, patient population, environments of use, technological characteristics, contraindications, or performance specifications. The differences do not raise new concerns of safety or effectiveness.
### Substantial Equivalence Conclusion -
The sponsor has demonstrated through performance testing, design and features, and non-clinical testing that the proposed device does not raise any new safety concerns compared to the predicates.

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.
