ORIGIO® Sperm Wash is intended for washing of spermatozoa, the isolation of motile viable sperm by swim-up method, dilution of ORIGIO gradients, and holding sperm for IUI procedure. ORIGIO® Gradient™ 100, ORIGIO® Gradient™ 90 and ORIGIO® Gradient™ 40/80 are for separation of motile sperm from the ejaculate by the density gradient method.
Device Story
ORIGIO® Sperm Wash and Gradient™ devices are reproductive media used in clinical laboratories for sperm preparation. Sperm Wash is a non-viscous solution used for washing, swim-up isolation, and IUI holding. Gradient™ devices (100, 90, 40/80) are viscous solutions containing silane silica to create density layers for separating motile sperm from ejaculate via centrifugation. Clinicians use these media to process semen samples; the resulting motile sperm are then used for fertility procedures. The devices are provided as sterile, aseptically filtered solutions in PETG bottles. By isolating high-quality, motile sperm, the devices assist in optimizing samples for clinical ART/IUI, potentially improving fertilization outcomes.
Clinical Evidence
Bench testing only. Testing included pH, osmolality, density, Human Sperm Survival Test (≥80% of control), endotoxin levels (≤0.15-0.8 EU/ml), and sterility (SAL 10^-3). Biocompatibility testing (cytotoxicity, sensitization, irritation) per ISO 10993-1:2009 confirmed safety for IUI use. Shelf-life and stability studies were conducted. Effectiveness of sperm separation was evaluated by comparing motility, morphology, viability, purity, and integrity against predicate devices, demonstrating comparable performance.
Technological Characteristics
Aseptically filtered, colorless solutions. Gradient™ devices contain silane silica for density; Sperm Wash is non-viscous. Ingredients include HSA, NaCl, bicarbonate, citrate, and taurine. PETG bottles with HDPE closures. Sterilization via aseptic filtration (EN/ISO 13408-2:2011). Shelf-life: 20-36 weeks unopened, 4 weeks opened.
Indications for Use
Indicated for use in assisted reproductive technology (ART) procedures for the separation of motile, viable sperm from ejaculate via density gradient or swim-up methods, and for holding sperm for intrauterine insemination (IUI).
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

### Predicate Devices:
SupraSperm™ System (K003404) from ORIGIO is the predicate device for ORIGIO® Gradient™ devices
Sperm Preparation Medium (K991332) from ORIGIO is the predicate device for ORIGIO® Sperm Wash.
### Device Description:
ORIGIO® Sperm Wash and ORIGIO® Gradient™ devices are for separation of motile sperm from semen and handling of sperm. These devices are based on the same formulation, but differ in the content of Human Serum Albumin (HSA), NaCl, bicarbonate, and silane silica. The silane silica generates the density, thus it is an ingredient in the ORIGIO® Gradient™ devices only and is not present in ORIGIO® Sperm Wash. All subject devices, except ORIGIO® Gradient™ 100, contain gentamicin and HSA.
The subject devices are aseptically filtered, colorless solutions. ORIGIO® Gradient™ devices are viscous while ORIGIO® Sperm Wash is non-viscous. They are contained in transparent polyethylene terephthalate glycol (PETG) bottles with high density polyethylene (HDPE) closures, available in card board boxes, individually labeled and with instruction for use provided as a package insert. The subject devices are quality control tested for the following specifications:

#### Indications for Use:
ORIGIO®Sperm Wash is intended for washing of spermatozoa, the isolation of motile viable sperm by swim-up method, dilution of ORIGIO® gradients, and holding sperm for IUI procedure.
ORIGIO®Gradient™ 100, ORIGIO® Gradient™ 90 and ORIGIO® Gradient™ 40/80 are for the separation of motile sperm from the ejaculate by the density gradient method.
#### Performance and Safety Data:
#### Product Specifications
The bench testing demonstrated that the subject devices met all product specifications.
#### Biocompatibility
Since ORIGIO® Sperm Wash can also be used for IUI (Intrauterine insemination), it mav have direct contact with the uterus (patient). In accordance with ISO 10993-1:2009, the cytotoxicity, sensitization and irritation tests have been conducted on this device and the results demonstrate that ORIGIO® Sperm Wash is safe.
#### Sterilization Validation
The subject devices are manufactured by aseptically filtration that was validated in accordance with EN/ISO 13408-2:2011. These products have a sterility assurance level (SAL) of 10-3.
#### Shelf-Life
The shelf-life study covering all product specifications has been conducted on the subject devices. The results demonstrate that Gradient™ 100 has a 20-week shelf-life whereas the other subject devices have a 36-week shelf-life in unopened bottle under recommended storage conditions. In addition, all subject devices are stable for four weeks under recommended storage conditions after the bottles have been opened.
#### Effectiveness of Separation of Motile Sperm
The sperm separated using subject devices were evaluated for motility, morphology. viability, purity and integrity in comparison with predicate and other cleared devices. The results demonstrate that the subject and predicate devices have comparable performance.

## Predicate Device Comparison:
## ORIGIO® Sperm Wash
ORIGIO® Sperm Wash and its predicate device have the same intended use. The subject device is different from predicate devices in pH; however, this difference is commonly seen in reproductive media. Regarding formulation, there are following differences between the subject and predicate devices:
- . Citrate is present in ORIGIO® Sperm Wash at higher concentration compared to the predicate device. However, citrate is a natural component in semen and present in much higher concentration than in ORIGIO® Sperm Wash.
- . Sodium bicarbonate is present in ORIGIO® Sperm Wash at lower concentration compared to the predicate device, but within the range of other cleared sperm wash media.
- . Unlike the predicate device, Synthetic Serum Replacement (SSR) is not present in ORIGIO® Sperm Wash. However, SSR is also absent in other cleared media intended for sperm handling. Therefore, absence of SSR is not considered detrimental for the sperm cells.
- . HSA concentration has been increased from 5 mg/ml in the predicate device to 10 mg/ml in ORIGIO® Sperm Wash. However, the level of HSA in ORIGIO® Sperm Wash is still much lower than physiological level.
- Taurine is present in ORIGIO® Sperm Wash but absent in the predicate device. ● However, taurine which is widely used in ART media, including cleared devices with similar indication.
Taken together, the differences do not raise new types of questions. Performance data shows that ORIGIO® Sperm Wash is as safe and effective as the predicate device. Therefore, ORIGIO® Sperm Wash is substantially equivalent to the predicate device in terms of safety and effectiveness.
### ORIGIO® Gradient™ devices
ORIGIO® Gradient™ devices and their predicate device have the same intended use. Gradient™ devices are different from the predicate device in pH and osmolality; however, these differences are commonly seen in reproductive media. Regarding formulation, there are following differences between the subject and predicate devices:
- ORIGIO® Gradient™ 40 contains a slightly higher concentration of NaCl, as ● compared to the predicate device, in order to adjust the medium to a slightly higher osmolality. However, the NaCl concentration used is still within the physiological range of semen.
- Taurine is present in ORIGIO® Gradient™ devices but absent in the predicate . device. However, taurine is widely used in ART media, including cleared devices with similar indication.
- HSA concentration has been increased to 5 mg/ml in ORIGIO® Gradient™ 40, 80 ● and 90. This concentration is within the normal range of cleared media intended for sperm.
{6}------------------------------------------------
- Citrate is present in ORIGIO® Gradient™ devices at higher concentration . compared to the predicate device. However, citrate is a natural component in semen and present in much higher concentration than in ORIGIO® Gradient™ devices.
- . ORIGIO® Gradient™ devices do not contain SSR or phenol red compared to the predicate device. However, absence of SSR and phenol red are commonly seen in cleared media intended for sperm and therefore, it is not considered detrimental for the sperm cells.
Taken together, the differences do not raise new types of questions. Performance data shows that ORIGIO® Gradient™ devices are as safe and effective as the predicate device. Therefore, ORIGIO® Gradient™ devices are substantially equivalent to the predicate device in terms of safety and effectiveness.
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.
