Indications for Use
The STERRAD® BI Test Pack is intended to be used as a standard method for frequent monitoring of the STERRAD® 100 Sterilizer cycle*. It functions as a routine test pack with both a biological sterilization process indicator and a chemical process indicator. Catalase Reagent is added to the Tryptic Soy Broth (TSB) medium, to neutralize the residual hydrogen peroxide on the biological indictor strip after sterilization. * See precautionary statement in Instructions For Use concerning the use of this product with the STERRAD 50 Sterilizer which reads in part as follows: PRECAUTION: The Certificate of Performance that accompanies these BI Test Packs contains data from the STERRAD® 100 Sterilizer. This information is unique to the STERRAD® 100 Sterilizer. The initial validation data submitted, based upon varying hydrogen peroxide concentration in the STERRAD® 50 Sterilizer, indicate that the BI Test Pack is acceptable for use with the STERRAD® 50 Sterilizer. The final performance data (D-value and Survival/Kill times) are not yet complete. Updated performance data for the BI Test Pack in the STERRAD® 50 Sterilizer will be provided by ASP as soon as it is available.
Device Story
STERRAD BI Test Pack monitors sterilization cycle efficacy in STERRAD 100 and 50 sterilizers. Device consists of plastic tray, Bacillus subtilis var. niger spore strip (10^6 spores), chemical indicator strip, and latex tubing. Tubing and narrow channels create diffusion-restricted environment to challenge sterilization process. Post-cycle, spore strip is incubated in Tryptic Soy Broth (TSB) with added catalase reagent to neutralize residual hydrogen peroxide. Chemical indicator provides visual red-to-yellow color change. Used by healthcare personnel in clinical settings to confirm sterilization success; results inform equipment release for patient use. Modification reduces incubation time to 48 hours and introduces pre-packaged catalase reagent vials for user convenience.
Clinical Evidence
Bench testing only. Validation performed per CDRH 1986 Guidance for Validation of Biological Indicator Incubation Time. Testing used three spore lots from three crops across different media lots. Results showed >=97% growth in 48 hours. Catalase concentration stability confirmed at 4°C, 25°C, and 40°C. Bacteriostasis testing confirmed excess catalase does not inhibit spore growth.
Technological Characteristics
Components: plastic tray, Tyvek/Mylar peel pouches, latex tubing, Bacillus subtilis var. niger spores (10^6), chemical indicator strip (red-to-yellow), catalase reagent. Sensing principle: biological indicator (spore kill) and chemical process indicator. Connectivity: none. Sterilization: intended for use in STERRAD hydrogen peroxide gas plasma sterilizers.
Indications for Use
Indicated for frequent monitoring of STERRAD 100 and STERRAD 50 sterilization cycles using biological and chemical indicators to verify sterilization efficacy.

## Description of Device
The STERRAD® BI Test Pack (BI Test Pack) consists of a plastic tray with a clear top which contains a STERRAD® Biological Indicator paper strip containing 106 Bacillus subtilis var. niger spores, a STERRAD® BI Test Pack Indicator Strip and a length of latex tubing. The BI spore strip is packaged in a Tyvek/Mylar peel pouch to protect the spore strip during handling.
The narrow opening and channels leading to the interior of the BI Test Pack and the absorptive properties of the latex tubing provide a diffusion restrictive environment which contributes to the effective resistance of the indicator organism. Included with the BI Test Pack are individual BI spore strips in Tyvek/Mylar peel pouches to serve as positive controls in the microbiological testing.
The STERRAD® BI Test Pack Chemical Indicator Strip included in the Test Pack serves as a chemical process indicator (Class A per EN867-1) for the STERRAD® Sterilizer cycle, Exposure of the chemical indicator strip to the STERRAD® Sterilizer cycle results in a recognizable color change from red to yellow.
#### Statement of Intended Use
The STERRAD® BI Test Pack is intended to be used as a standard method for frequent monitoring of the STERRAD® 100 Sterilizer cycle*. It finctions as a routine test pack with both a biological sterilization process indicator and a chemical process indicator.

# Description of Modification
The recommended incubation time for the STERRAD® BI Test Pack is being reduced to 48 hours based upon validation using The Center for Devices and Radiological Health, FDA Guide for Validation of Biological Indicator Incubation Time (1986).
For customer convenience, ASP now offers a catalase reagent for use with the STERRAD® BI Test Pack. Catalase has always been required for use with the STERRAD® BI Test pack. Previously, instructions were included for the user to make a catalase reagent. The reagent is supplied in single use dropper vials. The catalase reagent is sold in boxes of 50 vials.
### Summary of Nonclinical Tests
Testing was conducted using the CDRH Guidance Document Guide For Validation Of Biological Indicator Incubation Time (1986). Partial sterilization cycles were based on decrease in diffusion and plasma time. Three different spore lots, from three different spore crops, were used for this validation. Each test was performed using a different lot of media. All valid tests showed at least 97% growth in 48 hours,
Catalase concentration was confirmed at end of shelf life by a stability study conducted at 4°C, 25°C and 40°C.
Aseptic fill of the catalase vials was confirmed by process validation.
Excess catalase was shown to not effect the growth of spores by a Bacteriostasis test.
#### Substantial Equivalence
The modified STERRAD® BI Test Packs have the following similarities to those which previously received 510(k) clearance:
- have the same indicated use, ●
- use the same operating principle,
- . incorporate the same design
- . incorporate the same materials
- have the same shelf life, and �
- . are packaged using the same materials and processes.

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.
