Indications for Use
The Resectr Tissue Resection Device is intended for intrauterine use by physicians trained in hysteroscopy to resect and remove tissue, including focal lesions such as endometrial polyps.
Device Story
Resectr is a non-powered, manual hysteroscopic surgical instrument for intrauterine tissue resection. Operated by a physician trained in hysteroscopy, the device is inserted through a hysteroscope working channel. The device features a handle that, when manually squeezed and released, actuates an internal blade that oscillates radially to resect tissue. Resected tissue is evacuated through the device cannula via an external vacuum source connected to a vacuum tube port. Available in 5F and 9F sizes for compatibility with specific hysteroscope working channels. The device is supplied sterile for single use. By enabling controlled resection and removal of intrauterine lesions under direct visualization, the device assists in the treatment of conditions like endometrial polyps, potentially improving patient outcomes by facilitating minimally invasive tissue removal.
Clinical Evidence
No clinical data. Substantial equivalence is supported by non-clinical bench testing, including biocompatibility (ISO 10993), sterilization validation (ISO 11135), package integrity (ASTM D4169, F1886, F2096, F88), and mechanical performance testing (cutting performance, durability, vacuum loss, torque, and tensile strength) conducted at T=0 and T=3 years accelerated aging.
Technological Characteristics
Manual, non-powered hysteroscopic instrument. Available in 5F (1.65mm) and 9F (3.0mm) diameters. Features a radially oscillating blade actuated by a manual handle squeeze. Connects to an external vacuum source. Sterilized via Ethylene Oxide per ISO 11135:2014. Biocompatibility testing per ISO 10993. Mechanical testing per ASTM standards including D4169 (shipping), F1886 (seal), F2096 (leak), F88 (peel), and F1980 (aging).
Indications for Use
Indicated for intrauterine tissue resection and removal, including focal lesions like endometrial polyps, in patients undergoing hysteroscopy by trained physicians.

The Resectr device is a non-powered manual hysteroscopic surgical instrument used to resect and remove tissue under direct visualization. The device is supplied sterile for single use only. The device is offered in two sizes (5F and 9F) for compatibility with hysteroscopes with a 1.65mm or 3.0mm working channel respectively.
The following models/dimensions are available for the subject device:
| Model | Outer Diameter | Cannula Length | Resecting Window Length |
|-------------|----------------|----------------|-------------------------|
| M0065907051 | 5 Fr (1.65 mm) | 35 cm | 5.0 mm |
| M0065907041 | 9 Fr (3.0 mm) | 35 cm | 7.5 mm |
The working length (13.9"), materials of construction, and handle are identical for both models of the subject device.
{4}------------------------------------------------
#### SECTION 5
#### 510(k) SUMMARY
The Resectr devices consist of a handle that is manually squeezed and released to actuate a blade within the resecting window to resect and remove target tissue. The devices are provided assembled with a vacuum tube port for use with a suction source. As tissue is resected, it is evacuated through the length of the device and out the vacuum tube port.
#### F. Intended Use/Indications for Use
The Resectr Tissue Resection Device is intended for intrauterine use by physicians trained in hysteroscopy to resect and remove tissue, including focal lesions such as endometrial polyps.
#### H. Comparison of Intended Use and Technological Characteristics
The subject and the predicate devices have different indications for use statements. However, both devices are intended to be used hysteroscopically to resect and remove tissue. Therefore, the intended use of the subject and predicate device is the same.
The subject and predicate devices have similar technological characteristics, including method of use and mode of operation, outer tube rotation, resection aperture, tissue resection mechanism, device markings and sterility.
There are minor technological differences between the predicate and the proposed devices; however, the differences do not raise new questions of safety or effectiveness. The primary technological differences between the subject and predicate devices are:
- Outer Diameter: The Resectr device is offered in two sizes; 9F and 5F whereas the MyoSure device is only offered in 9F size.
- Working Length: The Resectr devices have a 13.9 inch cannula working length, whereas the MyoSure device has a 12.6 inch cannula working length.
- Vacuum and Tissue Collection: The Resectr devices are connected to an external vacuum source and tissue catch, whereas the MyoSure device is comprised of a hand-actuated vacuum and built-in tissue trap.
- . Supplied Accessories: The MyoSure device is provided with an inflow tubing set. whereas the Resectr devices are not.
- Directionality of the Resection Blade: The resecting blade on the Resectr devices oscillates radially relative to the cannula, whereas the resecting blade on the MyoSure device reciprocates axially with each handle squeeze.
- Blade Actuation: Each handle squeeze and release on the Resectr devices rotates the blade bi-directionally for a total of six resection actions across the cannula window. Each handle squeeze and release on the MyoSure device completes one resection action across the cannula window.
{5}------------------------------------------------

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.
