#### Overview of the Allient® Sorbent Hemodialysis System Device Description
The Allient Sorbent Hemodialysis System (Allient System) is intended for the treatment of acute or chronic uremic patients where hemodialysis is prescribed by the physician.
The system consists of the Allient hemodialysis machine, SORB™ series of Sorbent cartridges, a single-use, sterile, disposable blood tubing set, a singleuse disposable dialysate set, and various dialysate and infusate chemicals. The system is recommended for use with a variety of dialyzers, access needles or access cannulae, which will be supplied by other manufacturers.
Figure E-1 below is an illustration of the Allient System with major components of the system labeled for clarity.
Image /page/1/Figure/5 description: The image is a diagram of the Allient Sorbent Hemodialysis System. The diagram labels the different parts of the system, including the monitor, central status LEDs, dialysate bypass, dialysate out flow pump, blood pump, dialyzer, dialysate in flow pump, infusate, ammonia detector, dialysate inflow pump, venous clamp, venous air detector, heparin pump, arterial air detector, arterial clamp, dialysate reservoir, and IV pole. The diagram also shows the dialysate side and the blood side of the system.
The Allient System operates in a similar manner to standard hemodialysis systems currently approved for use. The only significant differences between the Allient System and standard hemodialysis machines are as follows:
The Allient System utilizes a Sorbent cartridge to purify dialysate made from potable water. After passing through the dialyzer, the dialysate is recirculated to the dialyzer instead of being disposed of. This contrasts with traditional
{2}------------------------------------------------
K043574 Page 3 of 9
"single pass" dialysis, which uses purified water, mixes it continuously with dialysate, and passes it across the dialysate side of a dialyzer membrane in a single flow-through system. Wastewater is routed to a drain and not recirculated. By recirculating and refreshing the dialysate, the Allient System uses 6 liters of water per dialysis treatment. A traditional single-pass dialysis system uses at least 120 liters of purified water during the typical 4-hour dialysis session.
The Allient System utilizes the Pulsar™ air-activated pump in contrast to the roller-activated pump commonly employed in traditional hemodialysis systems. The Pulsar blood pump is a dual-chamber pneumatically operated pump.
All other aspects of Renal Solutions' Allient Sorbent Hemodialysis System process are identical to those employed in the standard "single pass" method of dialysis: there are no significant differences in the technology employed in Sorbent dialysis therapy between the Allient System and traditional methods.
The Allient System functions as a traditional recirculating Sorbent hemodialysis system, similar to the REDY 2000 System. Either single-needle or dual-needle access to the patient is permitted.
The patient's blood is pumped from the access through a dialyzer and is returned to the patient. Heparin is administered via a flow-controlled heparin pump capable of delivering rates of 0 to 3 milliliter per hour (mL/hr) in 0.5 mL/hr increments as well as an initial bolus of 0 to 10 mL. Blood-flow rates are settable in 10 milliliter per minute (mL/min) increments in the range of 200 to 400 mL/min in the dual-needle mode and 200 to 300 mL/min in the singleneedle mode.
The dialysate delivery system consists of a container for dialysate. Sorbent regenerative cartridges, chemical infusion system to replace chemicals removed by the Sorbent cartridges, and an ultrafiltrate control system. The dialysate delivery system operates in a batch recirculating mode and continuously recirculates the dialysate through the cartridge. The cartridge removes dialyzed toxins from the dialysate and buffers the sodium and bicarbonate levels in the dialysate to maintain normal levels in the patient.
The Acute mode of operation is intended for use in a hospital, acute or chronic-care facility, or dialysis clinic where the patient is continually monitored. The Acute mode of operation allows the clinician or dialysis technician to enter prescription parameters and machine operating parameters for each patient.
The Allient System incorporates a Graphical User Interface (GUI) comprised of a touch-screen display, which controls the System software. The GUI is
{3}------------------------------------------------
Ko43574 Page 4 of 9
used to select the mode of operation of the Allient System and enter prescription data and machine control parameters during setup. This information is stored for future reference and verification prior to subsequent treatments. Treatment status and progress, in addition to machine status, is continually collected and displayed on the GUI screen to support treatment. The GUI's touch-screen technology also provides ease of use for Home patients. The Allient System incorporates a control system that contains a number of safety features and audible and visible alert and alarm functions to warn the operator or patient of unsafe conditions.

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.
