### DEVICE DESCRIPTION
The HAMILTON-TC1 is designed for adults and pediatrics requiring invasive or noninvasive ventilation support. Due to its compact design, a fully-loaded weight of only 6.5 kg (14.3 lbs), a twin-battery supply, and a built-in turbine; the HAMILTON-TC1 can accompany a ventilated patient everywhere within the hospital or outside the hospital when transport is needed. The HAMILTON-TC1 can run using AC or DC power. It does not need compressed air or O2 to drive the pneumatics, which reduces the weight load in the aircraft needed to operate the ventilator.
Since the HAMILTON-TC1 has been tested and evaluated for flight and high-altitude environments, it can be also used during patient transfer by emergency rescue vehicles, fixedwing aircraft, or helicopter. This makes the HAMILTON-TC1 especially relevant for Aeromedical Evacuations and Medevac operations.
The HAMILTON-TC1 ventilator uses the same graphical user interface (GUI) used by the HAMILTON-C2, featuring a touchscreen "Ventilation Cockpit"; this provides the exact information that the user needs and helps focus on what is important. In addition, the HAMILTON-TC1 includes the ASV ventilation-mode which automatically applies lung-protective strategies, reduces the risk of operator error, and promotes early weaning.
The HAMILTON-TC1's microprocessor system controls gas delivery and monitors the patient. The qas delivery and monitoring functions are cross-checked by an alarm controller. This crosschecking helps prevent simultaneous failure of these two main functions and minimizes the possible hazards of software failure.
The HAMILTON-TC1 is intended as a transport ventilator, based on the existing HAMILTON-C2, with minor adaptations to make the HAMILTON-TC1 capable of being used in high-altitude flight environments. The HAMILTON-TC1's changes include the following:
- 1. The HAMILTON-TC1 software is identical to the HAMILTON-C2's software, except that some of the options are not available with the HAMILTON-TC1, (e.g. Neonatal Ventilation & nCPAP-PS). Other features like Trends & Loops, NIV, NIV-ST, APRV, and DuoPAP are standard with the C2, but are only optional with the HAMILTON-TC1. The software is also different since the HAMILTON-TC1 includes a DC-power inlet.
- 2. The HAMILTON-TC1 has increased immunity from EMI, including >30 V/m. It also has extra safety features for the EMD, ESD, and RFI environments found on aircraft.
- 3. The unit is contained within an impact resistant case which protects the controls from damage and inadvertent manipulation. The enclosure for the HAMILTON-TC1 has been ruqgedized to withstand shock, vibrations, water ingress, and drops from >1 meter heights.
- 4. The HAMILTON-TC1 was tested for use in fixed and rotary-wing aircraft. Because mechanical ventilation can be challenging during air-medical transport, particularly due to the impact of changing barometric pressure with different altitude levels, the HAMILTON-TC1 automatically compensates for altitude changes. Adjusting provided- and measured-patient volumes accordingly, thereby eliminating the need for manual calculation and reducing the risk of error. This feature is similar to the Oxylog 3000.
- 5. The HAMILTON-TC1 has a "lock-button" which prevents an inadvertent change of settings. If screen lock is active, the following items are inactive: Touchscreen, Power/Standby switch, Print-screen key, Press-and-tum knob. Active are Alarm Silence, Manual Breath, O2 enrichment, Nebulizer. To switch off power, the user must press the On/Off button for > 3 s.

The intended use statement for the HAMILTON-TC1 ventilator is comparable to both predicate devices. Technological characteristics (i.e., design, material, energy source) and performance specifications of the HAMILTON-TC1 ventilator are substantially equivalent to those of the predicate devices. The HAMILTON-C2 and the HAMILTON-TC1 have been tested for volume, flow, and pressure waveforms. A baseline waveform analysis using the specific ventilation modes was done in order to evaluate the substantial equivalence of the HAMLTON-TC1 with the HAMILTON-C2. For airworthiness and transport aspects, the HAMILTON-TC1 is substantially equivalent to the Oxylog 3000. One of the tests used to evaluate the HAMLTON-TC1 in a high-altitude, low-pressure environment, was to place the HAMILTON-TC1 inside an altitude chamber to test the effects on the sensors and the ventilator measurements & readings. The detailed protocol and successful results for this test have been included with the submission.
The intended use of the HAMILTON-TC1 is covered by the referenced predicate devices. The materials and design are also similar to the predicate devices. The technical characteristics of the HAMILTON-TC1 do not raise any new questions regarding the safety or effectiveness of ventilators. The HAMILTON-TC1's software has gone through verification/validation tests. A complete revision level history, hazard analysis, and a traceability analysis linking requirements to validation were done. The conclusions drawn from the non-clinical tests demonstrate that the HAMILTON-TC1 is as safe, as effective, and performs as well as, or better than, the legally marketed devices. The HAMILTON-TC1 is, therefore, considered to be substantially equivalent to the currently marketed predicate devices which have been previously cleared by FDA.

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.
