The STARRT System is indicated for use as a secondary diagnostic tool for the further evaluation of women previously diagnosed with proximal tubal occlusion by hysterosalpingography or selective salpingography. The STARRT System is only designed to access the proximal portion of the fallopian tube, i.e. the first 2-3 cm. It should only be advanced as far as necessary to achieve a meaningful study, recognizing that possible adverse effects of more distal advancement, particularly upon normal tubes, have not yet been determined. The STARRT System is not intended for tubal recanalization, and there is no data available, in particular, pregnancy data, showing clinical benefit for this use. Studies are underway. The STARRT System is not to be used for gamete or embryo transfer, or other assisted reproduction techniques. The STARRT System should only be used by clinicians with experience in tubal evaluation.
Device Story
Stargate Falloposcopy Catheter is a single-lumen device used within the STARRT Falloposcopy System for diagnostic imaging of the proximal fallopian tube (first 2-3 cm). The device features a diamond-shaped wire tip at the distal end to guide the catheter and displace tubal epithelium from the falloposcope lens, optimizing visualization. It is delivered transcervically through a Coaxess Catheter positioned at the tubal ostium via a rigid hysteroscope. Operated by clinicians experienced in tubal evaluation, the device provides visual feedback to assist in diagnosing tubal health. The system includes a trifurcated irrigation tubing set for fluid infusion to clear the field of vision. Clinical benefit is derived from improved diagnostic accuracy compared to previous catheter iterations.
Clinical Evidence
Clinical testing validated device performance, with clinicians reporting improved diagnosis of tubal health compared to the predicate VS Catheter. Preclinical safety was established via a rabbit fallopian tube catheterization histology study, which showed no significant difference in tubal damage between catheterized and control tubes.
Technological Characteristics
Single-lumen catheter with graded shaft flexibility and a diamond-shaped wire tip at the distal end. Includes a trifurcated irrigation tubing set for fluid infusion. Designed for use with a falloposcope and guidewire. Mechanical design focuses on navigation and visualization optimization within the proximal fallopian tube.
Indications for Use
Indicated for women previously diagnosed with proximal tubal occlusion via hysterosalpingography or selective salpingography. Contraindicated for tubal recanalization, gamete/embryo transfer, or other assisted reproduction techniques.

Device to Which Substantial Equivalence was Claimed
Substantial Equivalence for the Stargate Falloposcopy Catheter was claimed to the
Conceptus VS™ Catheter which, as part of the STARRT Falloposcopy System, was previously cleared for the diagnosis of Proximal Tubal Occlusion (PTO). Substantial Equivalence for the Trifurcated Irrigation Tubing was claimed to the Clarus Medical, Model 5150 Tubing Set which was previously cleared for fluid infusion for clearing the field of vision with endoscopes.
Device Description
The Conceptus Stargate Catheter is a single lumen device with a graded shaft flexibility. The distal end has a diamond shaped wire tip designed to guide the catheter and to keep fallopian tube epithelium away from the falloposcope lens during imaging. The hub located at the proximal end of the Conceptus Stargate Catheter has two ports. The sideport is used for the attachment of the Trifurcated Irrigation Tubing set. The endport serves as a conduit for the introduction of the Conceptus Falloposcopy Guidewire and Falloposcope.

#### Device Description, cont.
The Conceptus Stargate Catheter and Falloposcopy Guidewire are transcervically delivered into the fallopian tube ostium through the lumen of the Coaxess™ Catheter which is delivered into the uterine cavity through the working channel of a rigid hysteroscope and positioned at the tubal ostium under hysteroscopic guidance. The Conceptus Stargate Catheter and Falloposcopy Guidewire are designed for use within the proximal portion of the fallopian tube (the first 2-3 cm of the tube).
#### Intended Use
The Stargate Catheter as part of the STARRT Falloposcopy System is intended for use as a secondary diagnostic tool for further evaluation of women previously diagnosed with proximal tubal occlusion by hysterosalpingography or selective salpingography.
## Technological Characteristics
The Conceptus Stargate Catheter is substantially equivalent to the Conceptus VS Catheter and will replace that device in the Conceptus STARRT Falloposcopy System. The primary difference between the Stargate Catheter and VS Catheter is a diamond shaped wire which has been added to the distal tip of the Stargate Catheter. The primary purpose of the wire tip is to keep tubal epithelium away from the falloposcope lens to optimize imaging of the fallopian tube lumen.
### Data Supporting Substantial Equivalence
Conceptus conducted laboratory, preclinical and clinical testing to confirm that the Stargate Catheter is safe and effective. The laboratory testing demonstrated that small forces are applied to the wire tip during clinical use. Laboratory testing further demonstrated that the force required to advance the Stargate Catheter is no greater than the force required to advance the VS Catheter. Lastly, laboratory testing confirmed that the Stargate Catheter is less likely to kink as compared to the VS Catheter.
A fallopian tube catheterization histology study in rabbits was conducted to demonstrate the safety of the Stargate Catheter. The objective of the study was to use the rabbit model to determine if fallopian tube catheterization as well as anticipated adverse events cause damage to the fallopian tube and if there is any resulting adverse impact on pregnancy rates. Study results demonstrate that their is no significant difference in fallopian tube damage between the catheterized and control tubes.
Lastly, clinical testing was conducted to validate the performance of the device. Participating clinicians reported that they were able to make a better diagnosis of tubal health with the Stargate Catheter as compared to the VS Catheter.

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.
