RAPIDVIT BLAST, RAPIDWARM BLAST
Vitrolife Sweden AB
Routine clinical IVF treatment records
Clinical data from patients undergoing routine IVF treatment were analyzed to confirm the safety and efficacy of the RapidVit™ Blast and RapidWarm™ Blast devices, specifically reporting pregnancy rates and the birth of healthy babies.
Patients undergoing IVF treatment with vitrified and warmed blastocysts
Not applicable for this study
Blastocyst survival, pregnancy rate, birth of healthy babies
Indications for Use
RapidVit™ Blast is intended for vitrification of human blastocyst stage embryos. RapidWarm™ Blast is intended for warming of vitrified human blastocyst stage embryos.
Device Story
RapidVit™ Blast and RapidWarm™ Blast are embryo-physiological solutions for cryopreservation. RapidVit™ Blast uses three solutions with increasing cryoprotectant concentrations (1,2-propanediol, ethylene glycol, sucrose) to dehydrate blastocysts and increase osmolality prior to vitrification. RapidWarm™ Blast uses three solutions with decreasing sucrose concentrations to rehydrate embryos post-thaw. Used in IVF clinics by embryologists; solutions maintain physiological pH via MOPS buffer. Process enables blastocyst survival, development, and hatching post-warming, facilitating embryo transfer. Benefits include successful cryopreservation of blastocysts for future clinical use.
Clinical Evidence
Clinical investigation of vitrified/warmed blastocysts showed high survival rates and successful pregnancy outcomes. Study reported 43 healthy babies born from vitrified/warmed blastocysts. No adverse effects or complications reported. Nonclinical studies included three studies on surplus human blastocysts demonstrating survival, development, and hatching, plus in situ hybridization analysis for chromosomal abnormalities showing results comparable to fresh blastocysts.
Technological Characteristics
Embryo-physiological solutions containing 1,2-propanediol, ethylene glycol, and sucrose. Uses MOPS buffer for pH maintenance. Formulated as multi-step kits for vitrification and warming. Non-automated, manual handling process.
Indications for Use
Indicated for vitrification and warming of human blastocyst stage embryos in IVF clinical settings.
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.

#### Intended Use:
RapidVit™ Blast is intended for vitrification of human blastocyst stage embryos
RapidWarm™ Blast is intended for warming of vitrified human blastocyst stage embryos
#### Technological Characteristics:
RapidVit™ Blast and RapidWarm™ Blast are devices used for vitrification of blastocysts. The cryoprotectants 1,2-propanediol and ethylene glycol are used together with sucrose for dehydration of the embryo before cryopreservation.
For RapidVit™ Blast and RapidWarm™ Blast two predicate devices have been utilized:
#### Rapid Vit™ Cleave and RapidWarm™ Cleave as predicate device
The Rapid Vit™ Blast and RapidWarm™ Blast device is a modification of the RapidVit™ Cleave and RapidWarm™ Cleave device (K080446) currently marketed by Vitrolife Sweden AB for the vitrification of day 3 cleavage stage embryos.
Rapid Vit™ Blast and RapidWarm™ Blast is similar to the predicate device in most respects. However, the predicate device RapidVit™ Cleave and RapidWarm™ Cleave (K080446) is intended for vitrification of day 3 cleavage stage embryos. RapidVit™ Blast and RapidWarm™ Blast and the predicate device consist of the same components but in somewhat different proportions as they are tailor-made for blastocysts and for cleavage stage embryos respectively.
## Vit Kit™ - Freeze/Vit Kit™ - Thaw as predicate device
Vit Kit™ - Freeze/Vit Kit™ - Thaw and RapidVit™ Cleave/RapidWarm™ Cleave are embryo-physiological solutions supplemented with permeable and non-permeable cryoprotectants.

## Main differences between Vit Kit™ - Freeze/Vit Kit™ - Thaw and RapidVit™ Blast/RapidWarm™ Blast
Blast/Rapid Warni--- Diast
The main differences between RapidVit™ Blast and RapidWarm™ Blast and Vit Kit™ - Freeze and Vit Kit™ - Thaw are the following:
- Vit Kit™ Freeze and Vit Kit™ Thaw contain ethylene glycol, DMSO and . Vit Kit ---------------------------------------------------------------------------------------------------------------------------------------------------------------------contain ethylene glycol, 1,2-propanediol and sucrose
- Vit Kit™ Freeze and Vit Kit™ Thaw use an HEPES buffer, while . V It Kit --- Preczed and RapidWarm™ Blast use a MOPS buffer to keep the pH within physiological values during handling outside the incubator
## Justification for use of different media composition
Justification for use of annoverison, in spite of the somewhat different media The Justification for this comparison, in Spice of and Vit Kit™ - Freeze/Vit Kit™ - Thaw, is as follows:
- Most ART centres are now using either 1,2-propanediol or DMSO as the � Most ANT contres are now asing online of embryos. 1,2-propanediol is considered less toxic for embryos and for users
- The MOPS buffer used in RapidVit™ Blast and RapidWarm™ Blast is similar . The MOPS buffer used in Napld vit - Diast and Nit Kit™ - Thaw In addition
to HEPES which is used in Vit Kit™ - Freeze and Vit Kit™ - Thaw of hear lo HEFES winch is used in VR Rt.
the MOPS buffer is used in most of the IVF Media from Vitrolife, and has been used clinically for a very long time with good results

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.
