#### DEVICE DESCRIPTION 4.
The Harris Medical RH 3500 Transport Chair is a manually operated wheelchair that is propelled by human power. Its intended function and use is to provide mobility to a person limited to a sitting position. It may be used as an attendant propelled transport device in a healthcare environment such as a hospital, nursing home or extended care facility. The wheelchair consists primarily of an aluminum frame; 5 inch rear and front casters and handles for the wheelchair to be pushed. It
{1}------------------------------------------------
is a rigid or non-folding type of wheelchair that is designed for use by a patient weighing up to 250 lbs.
The frame is constructed of one inch (1) outside diameter Aluminum tube that is welded that has a wall thickness of 1/8 inch. The rear urethane wheels are fixed and front are urethane casters.
#### ડ. INTENDED USE
The RH 3500 EZ transport Chair is intended to transport patients within acute, alternative and long-term care facilities. The device can be operated indoors on carpeting, linoleum and other floors and on sidewalks. The RH 3500 EZ transport chair is controlled, steered and operated completely by a trained caregiver.
#### 6. TECHNOLOGICAL CHARACTERISTICS
The RH 3500 is intended to be used by a trained caregiver that provides the human energy to operate the chair. The chair uses no other internal or external power source, such as battery power or AC power to perform any of its functions. The chair uses a foot pedal to activate the hydraulic pump to provide the pressure to rise and lower the chair. The hydraulic pressure causes the cylinder to move and activate the scissor jack up and down. This engineering approach has been used for many years to elevate various static objects such as cars, boats and people. The hydraulic system consists of a pump that is activated by a foot pedal, a hose, hydraulic piston (Cylinder) and a lever release or control value.
The technological characteristics of the RH 3500 EZ Transport Chair are very similar to the predicate devices, except the Breez 1025 and the 1-1000 use electrical energy to operate the chair. This difference when compared to the RH 3500 raises no new safety issues. In fact the RH3500 has a lower technological risk than the cleared predicates because of a much simpler mechanical approach.
The frame material most commonly used for chairs (Wheel or Transport) is aluminum or steel and both have advantages, weight vs. cost. Both materials have a long history of meeting the design needs of the product life cycle. The wheels (Casters) used on the predicates and the RH3500 are similar in size, and the differences are acceptable.
{2}------------------------------------------------
The RH 3500 EZ transport chair has been tested with loads of 375 Ibs. (50% overload) for periods of 24 hours with out any adverse events. The hydraulic system held without any position changes.
The RH 3500 is constructed from the following materials: Aluminum alloy 6063T for the frame. The casters have a capacity of 3001bs and made from steel and the wheels are grey non-marking injection molded rubber. The cover to the seat, back and leg rest is a 4 way stretch urethane knit fabric commonly used for this type of application.
#### 7. SUBSTANTIAL EQUIVALENCE
The Harris Medical RH3500 EZ Transport Chair is substantially equivalent to Invacare Corporation manual wheelchairs (ALB19HBFR). The above device was granted marketing clearance by the FDA on March 1st 1994, under 510K number K 935398 and Electro kinetic Technologies K111095 and Barton Medical, K071793.
#### 8. PERFORMANCE STANDARDS
No performance standards applicable to this device have been adopted under Section 514 of the Act.
The RH3500 passed a 24 hour sustained 50% overload test, a determination of strength. The results confirmed an allowable patient load of 250lbs.
The laterally, posteriorly and anteriorly tiltover test was performed on the RH3500 EZ transport chair as per the guidance document for mechanical wheelchairs. The conclusion drawn from this testing is that this chair is as safe as the predicate devices.
The materials used for the seat cover is a 4 way stretch urethane knit fabric and is certified by the manufacture to be fully compliant to the following: flame resistance Cal TB 117, Antibacterial AATCC 147-2004, Antifungal AATC 30-2004, and Non-irritant Draize Dermal Toxicity OECD testing #404, 2002.
The seat belt used meets the following Federal standard FMVSS209-302.

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.
