Indications for Use
The THINK Surgical TCAT® TKA Instrument Tray is intended to protect, organize and deliver to the surgical field TCAT® tools, instruments and accessories. The tray allows sterilization of TCAT® tools, instruments and maintains sterility of the enclosed devices until used. The tray is wrapped with an FDA-cleared sterilization wrap during the pre-vacuum autoclave sterilization process.
Device Story
TCAT® TKA Instrument Tray is a reusable, perforated container designed to organize, sterilize, store, and transport surgical instruments for TSolution One® Total Knee Application (TKA) procedures. Constructed of anodized aluminum with silicone, nylon, and stainless steel components, the tray features a rectangular base, latchable lid, and a lift-out tray with stanchions to secure specific tools. The device is used in clinical settings; it is loaded with instruments, wrapped in an FDA-cleared sterilization wrap, and processed via pre-vacuum autoclave. The tray facilitates sterilant penetration and drying through its perforated design. It does not provide a sterile barrier independently; it relies on external sterilization wrap. The tray benefits the patient by ensuring surgical instruments are organized, sterile, and ready for use during TKA procedures.
Clinical Evidence
No clinical or animal testing was performed. Substantial equivalence is supported by bench testing, including sterilization efficacy (BI Overkill method achieving six-log reduction), shipping/packaging validation per ASTM D4169-16, handle strength testing per ASTM ST77:2013, and verification of product requirements via inspection and laboratory analysis.
Indicated for the protection, organization, and delivery of TCAT tools, instruments, and accessories to the surgical field for use with the TSolution One® Total Knee Application.

# Predicate Device:
TCAT® TKA Instrument Tray Set cleared via K200632.
### Device Modifications:
The changes to the predicate device allow tools, instruments and accessories to be utilized during a total knee arthroplasty (TKA) procedure. The modifications to this device are there is one tray with a lift out tray which contains tools, instruments and accessories for a total knee arthroplasty, the addition of a silicone mat ('utility area'), and the addition of a 13mm Recovery Marker holder.
### Device Description:
The TCAT® TKA Instrument Tray is intended only for use with TSolution One® Total Knee Application instruments, tools and accessories. This tray is used to enclose and hold the instruments, tools and accessories in an organized manner during the sterilization process and subsequent storage and transportation to and from the surgical suite. The tray is designed to fit any standard autoclave and is constructed primarily of anodized aluminum. The tray is compatible with repeated steam sterilizations. The tray has perforations to facilitate sterilant penetration, evacuation and drying. Since the tray is perforated, an FDA-cleared sterilization wrap must be used to maintain sterility of the contents.
{5}------------------------------------------------
The trav has the basic same size and a minor configuration change to the predicate device: a rectanqular base with a latchable lid and a lift out tray. The tray has perforations with an evenly distributed hole pattern on the lid, bottom, and sides to allow sterilant penetration. The bottom tray surface and lift out tray surface contain stanchions designed to separately hold each individual instrument, tool and accessory for effective sterilant exposure, sterilant evacuation and drying the entire duration of the sterilization process, as well as ease of locating each instrument when placing in or removal from the tray. The lift out tray contains a silicone mat which may used to sterilize additional THINK Surgical part.
The instrument tray has been tested only with THINK Surgical instruments, tools and accessories for a 4 minute sterilization cycle of pre-vacuum steam sterilization at 132°C, with a 60 minute dry time. While reuseable, these trays will not be serviced or repaired. The type and maximum number of instruments, tools and accessories included in the tray follow:

{7}------------------------------------------------
# Comparison of Technological and Performance Characteristics
Three fundamental characteristics are the same between the subject device and predicate devices:
- 1. Basic design: Both the TCAT® TKA Instrument Tray and the predicate device have a basic lid/trav design with latches, handles, perforations, and contoured inserts or sections for containing items for sterilization, storage and transport. General size, shape, and weight of both the subject device and predicate device are similar. The materials of the subject device and the materials of the predicate device are the same.
- 2. Role in sterile barrier system: The TCAT® TKA Instrument Tray and the predicate device must be wrapped with an FDA-cleared sterilization wrap to maintain sterility. Neither the subject device nor the predicate contains gaskets, valves or filters.
- 3. Fundamental technology: The TCAT® TKA Instrument Tray and the predicate device allow the sterilant (steam) to penetrate and render its contents sterile by relving on surface perforations.
The following tables provide a comparison of technological characteristics between the subject device and the predicate device (Table 4) and a summary of non-clinical performance testing (Table 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.

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.
