Indications for Use
GM501 Wash is intended for in vitro procedures involving handling and micromanipulation of human occytes and embryos outside of a CO> incubator. Include oocyte and embryo washing (e.g. after oocyte aspiration, after hyaluronidase treatment to remove cumulus cells, before and after cryopreservation, and before embryo transfer) and micromanipulation procedures (e.g. assisted hatching). GM501 Wash is not intended for use in transferring embryos into the uterine cavity.
Device Story
GM501 Wash is a ready-to-use solution for handling/micromanipulation of human oocytes and embryos outside CO2 incubators; used during ART procedures like washing post-aspiration, post-hyaluronidase treatment, pre/post-cryopreservation, and pre-transfer. Aseptically filled in sterilized bottles; shelf-life 6 months; stable 7 days post-opening. Clinicians use the solution to maintain optimal conditions for oocytes/embryos during benchtop procedures. Output is a treated/washed biological sample; facilitates safe handling and micromanipulation; benefits patient by supporting embryo viability during necessary laboratory steps.
Clinical Evidence
Bench testing only. Studies included pH, osmolality, sterility (USP <71>), endotoxin (USP <85>), and Mouse Embryo Assay (MEA). MEA demonstrated ≥80% blastocyst development at 96h following 1h exposure. Shelf-life and post-opening stability testing confirmed specifications met over 6 months and 7 days, respectively.
Technological Characteristics
Aqueous solution containing salts (NaCl, KCl, MgSO4, CaCl2), glucose, amino acids, HEPES, HSA, and pyruvate. Sterilized via aseptic filtration per ANSI/AAMI/ISO 13408-1:2008(R)2011 and 13408-2:2003(R)2013. Osmolality 270-290 mOsm/kg; pH 7.2-7.5. Packaged in 20, 50, 500 ml bottles.
Indications for Use
Indicated for in vitro handling and micromanipulation of human oocytes and embryos outside of CO2 incubator, including washing and assisted hatching. Not indicated for uterine embryo transfer.
Regulatory Classification
Identification
Reproductive media and supplement are products that are used for assisted reproduction procedures. Media include liquid and powder versions of various substances that come in direct physical contact with human gametes or embryos (including water, acid solutions used to treat gametes or embryos, rinsing solutions, sperm separation media, supplements, or oil used to cover the media) for the purposes of preparation, maintenance, transfer or storage. Supplements are specific reagents added to media to enhance specific properties of the media (e.g., proteins, sera, antibiotics, etc.).
Special Controls
*Classification.* Class II (special controls) (mouse embryo assay information, endotoxin testing, sterilization validation, design specifications, labeling requirements, biocompatibility testing, and clinical testing). The device, when it is phosphate-buffered saline used for washing, and short-term handling and manipulation of gametes and embryos; culture oil used as an overlay for culture media containing gametes and embryos; and water for assisted reproduction applications, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 884.9.

{5}------------------------------------------------
As noted above, the subject and predicate media products have intended use for oocytes and embryos (i.e., short term use in handling, washing, and manipulation procedures outside of an incubator), with the exception of embryo transfer procedures, which represents a more limited indications for use for the subject device as compared to the predicate.
In addition, the two media products have similarities in specifications (pH, osmolality, sterility, etc.) and sterilization methods. However, differences exist in media formulation, endotoxin and MEA specifications, and shelf-life duration for the different media products. As discussed in the table above, these differences do not raise different questions of safety and effectiveness as compared to the predicate device, and can be assessed through performance data.
## Summary on Non-Clinical Performance Testing:
The following studies have been performed to support substantial equivalence to the predicate device:
- pH testing (acceptance criterion: 7.2-7.5) ●
- Osmolality testing (acceptance criterion: 270-290 mOsm/kg)
- Aseptic filling validation per ANSI/AAMI/ISO 13408-1:2008(R)2011, ANSI/AAMI/ISO 13408-. 2:2003(R)2013, and the FDA's "Guidance for Industry: Sterile Drug Products Produced by Aseptic Processing - Current Good Manufacturing Practice."
- . Sterility testing per USP <71> (acceptance criterion: no growth)
- Bacterial endotoxins testing per USP <85> (acceptance criterion: <0.25 EU/ml) ●
- Mouse Embryo Assay (MEA) using established protocol:
One-cell mouse embryos were exposed to GM501 Wash for one hour to represent the worst-case exposure for this short-term use medium. The embryos were transferred to culture medium and cultured at 37°C in an atmosphere containing 5% CO2. The percentage of embryos developed to the blastocyst stage within 96 hours were assessed in comparison with the control group. The acceptance specification is ">80% blastocysts at 96h following a 1h exposure to GM501 Wash."
{6}------------------------------------------------
- Shelf-life testing was conducted to ensure that device specifications for the following parameters are met at time zero and at the end of shelf-life (6 months): pH, osmolality, sterility, 1-cell MEA, and endotoxin
- Stability testing after bottle opening was conducted to ensure that device specifications for the following parameters are met seven days after opening of bottles: pH, osmolality, sterility, 1-cell MEA, and endotoxin.
### Conclusion:
The subject and predicate devices have the same intended use and comparable technological characteristics. The differences in technological characteristics between the subject and predicate devices do not raise different questions of safety and effectiveness. The performance data demonstrate that the subject device is substantially equivalent to the predicate device.

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.
