Indications for Use
The MAKO 7 is a hysteroscope accessory, placed through the working channel of a hysteroscope to obtain samples from the fallopian tube for cytological evaluation.
Device Story
MAKO 7 is a sterile, single-use hysteroscope accessory used in hospitals or clinics. Operated by a physician, the device is inserted through the working channel of a hysteroscope under visual guidance. The device consists of a handle with a drive wheel and a catheter featuring a balloon. The physician positions the distal tip near the fallopian tube ostium, advances the balloon into the tube, and collects cells on the balloon surface. The handle connects to an external inflation device via a 3-way stopcock. The collected samples are intended for cytological evaluation to assist in clinical diagnosis. The device facilitates minimally invasive cell collection from the fallopian tube, providing diagnostic information without requiring more invasive surgical procedures.
Clinical Evidence
Prospective, single-arm study of 40 subjects (80 fallopian tubes) undergoing laparoscopic tubal ligation. Primary endpoints: navigation success, sample adequacy, and adverse events. Access achieved in 71/80 (89%) tubes; 9 failures due to pre-existing occlusion. 70/71 (99%) samples were adequate for cytological evaluation. No device-related adverse events reported.
Technological Characteristics
Catheter includes balloon, stainless steel/Nylon shaft, Nylon 12 sheath, and polycarbonate knob. Handle includes drive wheel and luer-connected extension tube. Sterile, single-use, EO-sterilized. External communicating device, mucosal membrane contact, <24 hours duration. Mechanical actuation via drive wheel.
Indications for Use
Indicated for use as a hysteroscope accessory to obtain fallopian tube samples for cytological evaluation in patients undergoing hysteroscopic procedures.

#### IV. DEVICE DESCRIPTION
The MAKO 7 is a hysteroscope accessory intended to collect cell samples from the fallopian tube. The device is comprised of a catheter and a handle. The catheter includes a balloon, a shaft (which is made up of a stainless steel tube and a Nylon tube), a sheath (Nylon 12), and a sheath knob (Polycarbonate). The handle includes a drive wheel and an extension tube that is attached to a luer in the handle body. The extension tube attaches to a commercially available inflation device via a commercially available 3-way stopcock.
In summary, the physician inserts the MAKO 7 into the working channel of the hysteroscope until the distal tip of the catheter is positioned immediately proximal to the ostium of the fallopian tube. Then, the balloon is advanced into the fallopian tube and cells are collected on its surface.
The MAKO 7 is a sterile, single-use device. The device is terminally sterilized using ethylene oxide (EO).
The device is intended for use in the hospital/clinic/physician's office.
The duration and type of contact is classified as follows:
- Category: External Communicating Device ●
- Contact: Mucosal membrane
- Duration: A - Less than 24 hours
#### INTENDED USE/INDICATIONS FOR USE V.
The indications for use for the subject device are as follows:
The MAKO 7 is a hysteroscope accessory, placed through the working channel of a hysteroscope to obtain samples from the fallopian tube for cytological evaluation.
The indications for use differ from that of the predicate, in that the indication for use for the subject device refers to the collection of samples from the fallopian tube instead of the proximal fallopian tube only. This difference does not represent a new intended use, since 1) device use is in the same anatomical structure – the fallopian tube, and 21 the difference in location within the fallopian tube does not alter the general purpose of the device to collect cells for cytological evaluation. As described in FDA's July 2014 guidance regarding evaluating substantial equivalence, the proposed indication is a "tool type" indication, which is not affected by the change in location within the fallopian tube.
{5}------------------------------------------------
Also, reference to device use in the fallopian tube does not raise different questions of safety and effectiveness as compared to use within the proximal portion of the fallopian tube.
#### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The mechanism of action and principles of operation of the subject device and the predicate device are identical. Both devices use an identical handle, catheter body, and, most distally, a balloon that collects the sample. For both devices, this distal portion is actuated by a drive wheel on the handle and a hysteroscopic view is required.
There is only one difference in design between the predicate device and the subject device. This difference is that the balloon of the subject device extends 7cm into the fallopian tube while the balloon of the predicate device extends 2.5cm into the fallopian tube.
Since the subject and predicate devices collect cells by the same mechanism and in the same anatomical structure, and because the handle body, catheter body, and cell collection portion are the same, the subject device does not raise different questions of safety or effectiveness. There are also no new risks for collection of cells in the fallopian tube as compared to cell collection in the proximal fallopian tube. Indeed, in a clinical study of the subject device, no adverse events were reported.
#### VII. PERFORMANCE DATA
Nonclinical and clinical testing included the following:
## Mechanical testing
- Dimensional (sample size of n=15 was used for each test) ●
- Deployment (sample size of n=15 was used for each test) ●
- Inflation Pressure (sample size of n=15 for each test)
## Ergonomics
- Physician feedback on MAKO 7 confirmed handle ergonomics, drive wheel ● ergonomics, hysteroscopic visibility of balloon deployment, and ability to follow the IFU.
- . A sample size of 3 physicians per parameter was used.
## Clinical testing
A prospective, single-arm clinical study was conducted to demonstrate the safety and effectiveness of the subject device in navigating the fallopian tube and obtaining cell samples. The MAKO 7 was evaluated in 40 subjects (80 fallopian tubes) who were already scheduled to undergo a laparoscopic tubal ligation.
{6}------------------------------------------------
Study endpoints included 1) ability of the device to navigate the fallopian tube, 2) ability of the device to collect a sample adequate for cytological evaluation, and 3) adverse events. Access was achieved in 71/80 (89%) fallopian tubes. The remaining 9 tubes were determined to have pre-existing tubal occlusion, as determined by methylene blue dye injection (in two of the tubes not initially accessed a second access and navigation was successful after incidental clearing of tubal blockage after methylene blue dye injection).
The study pathologist determined that 70/71 (99 %) of the samples were adequate for cytological evaluation.
There were no device-related adverse events reported.
#### VIII. CONCLUSION
The bench and clinical performance data provided in support of the 510(k) confirm that the MAKO 7 subject device is as safe and effective and substantially equivalent to the MAKO 2.5 predicate device.

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.
