Device Story
Extracorporeal bypass circuit component; provides oxygenation, CO2 removal, and temperature control. Input: venous or suctioned blood. Oxygenator uses microporous capillary polypropylene fibers in crossed mat configuration; blood flows outside fibers, gas inside. Integral heat exchanger (epoxy-coated pleated stainless steel) manages blood temperature. Softshell venous reservoir (flexible plastic bag with screen and rigid backplate) collects venous/cardiotomy blood, filters air bubbles, and allows purging via double purge line with one-way valve. Operated by perfusionists in surgical settings. Output: oxygenated blood returned to patient. Benefits: maintains normothermia/hypothermia and gas exchange during bypass. Clinicians monitor arterial temperature via integrated probe and CO2 via capnograph connector on gas outlet.
Clinical Evidence
No clinical data. Evidence consists of in vitro bench testing. Performance metrics included gas exchange (O2/CO2 transfer), blood side pressure drop, heat exchanger efficiency, hemolysis, cell depletion, air removal efficiency, and mechanical integrity (burst/leak tests). Biocompatibility testing performed for external-communicating, circulating blood contact devices (duration ≤ 24 hours).

## 4. Device Intended Use and Description
The MONOLYTH C Hollow Fiber Membrane Lung with Integrated Softshell Venous Reservoir is intended for use in an extracorporeal bypass circuit. The device provides oxygenation and removal of carbon dioxide from venous or suctioned blood. The integral heat exchanger provides blood temperature control, allows for the use of hypothermia, or aids in the maintenance of normothermia during surgery. The integral venous reservoir is intended for use as a storage reservoir for blood. The device is indicated for use with blood flows of 1.0 - 8.0 liters per minute (LPM). The MONOLYTH C 600 and the MONOLYTH C 1200 have been tested for 6 hours of continuous use. Use longer than 6 hours is not advised.
{1}------------------------------------------------
The MONOLYTH C is a high efficiency hollow fiber oxygenator with integral heat exchanger and a softshell venous reservoir. The venous reservoir is available both integrated with the device or as a separate device.
The oxygenator consists of microporous capillary polypropylene fibers wound around a perforated core in a crossed mat configuration. The fiber bundle has a surface area of approximately 2,2 m2. The blood path is around the outside of the fibers, while the gas path is through the lumens of the fibers. An arterial temperature probe is located close to the arterial outlet. The arterial sampling line contains an integrated one-way valve to prevent accidental air injection. The gas outlet is equipped with a capnograph connector for CO2 measurement. The gas outlet cap has a safety anti-occlusion feature to aid in gas venting.
A line between the gas module and the venous reservoir facilitates gravity priming of the system and allows for recirculation. This line is accessed via a high-pressure stopcock located at the lower portion of the membrane. The stopcock provides access to arterial blood throughout the procedure for cardioplegia, perfusion, or blood concentration.
The heat exchanger is on the venous side of the device and is comprised of epoxy-coated pleated stainless steel. The heat exchanger has a surface area of 0.17 m2.
The softshell venous reservoir is attached to a rigid external shell which is mounted on top of the oxygenator module. The softshell venous reservoir is a soft, flexible plastic bag with an integral screen and a rigid backplate. The backplate contains two inlet ports, a recirculation port, and a temperature probe port. The reservoir collects blood coming from venous return and from the cardiotomy reservoir. Blood from venous return and from the cardiotomy reservoirs is collected via separate inlet ports. Blood is then filtered through the screen to deflect air bubbles to the top of the reservoir. Bubbles may be purged through a double purge line with an additional luer port located at the top of the reservoir, which join together into a common line. The common purge line contains a one-way valve which prohibits air from returning into the reservoir. The temperature port, located below the venous inlet port, is designed to receive a YSI series 400 compatible probe.
The venous reservoir has one outlet line located at the bottom center of the bag. A 1/4-inch recirculation line is attached to a port on the back of the reservoir. This line may be connected to the arterial outlet or the recirculation port of the oxygenator to recirculate blood back to the venous reservoir.
# 5. Substantial Equivalence
The MONOLYTH C Hollow Fiber Membrane Lung with Integrated Softshell Venous Reservoir is substantially equivalent to the Sorin Monolyth Integrated Membrane Lung (510(k) K922933, cleared November 30, 1992) and the Monolyth Venous Reservoir (510(k) K933481, cleared November 12, 1993), both manufactured by Sorin Biomedical Inc. The intended use, design, materials, and manufacturing processes of the MONOLYTH C are substantially equivalent to those of the predicate devices.
{2}------------------------------------------------
The intended use of the MONOLYTH C Hollow Fiber Membrane Lung with Integrated Softshell Venous Reservoir is identical to the intended use of the Monolyth Integrated Membrane Lung. Both devices are intended for the adult population who undergo cardiopulmonary bypass surgery requiring extracorporeal circulation.
The oxygenator of the MONOLYTH C Integrated Membrane Lung with Integrated Softshell Venous Reservoir is identical to the oxygenator used in the MONOL YTH Integrated Membrane Lung. The MONOLYTH Integrated Membrane Lung has been modified to attach a softshell venous reservoir in place of the hardshell venous/cardiotomy reservoir. The softshell venous reservoir is substantially equivalent in intended use, design, and manufacturing processes as the Monolyth Venous Reservoir (MVR).
# 6. Testing Summary
In vitro studies were conducted to evaluate the performance characteristics and mechanical integrity of the Monolyth C Hollow Fiber Membrane Lung with Integrated Softshell Venous Reservoir and the CVR Softshell Venous Reservoir. Oxygenator in vitro testing were performed and presented in the original 510(k) (K922933): gas exchange study (oxygen transfer and carbon dioxide transfer), operating blood volumes, blood side pressure drop, heat exchanger study, mechanical integrity study (blood path and heat exchanger burst and leak tests).
To address the modification to the oxygenator/reservoir, additional in vitro testing was performed on aged and unaged MONOLYTH C Hollow Fiber Membrane Lung with Integrated Membrane Lung with Softshell Venous Reservoir and on CVR Softshell Venous Reservoirs. Product performance testing included hemolysis and cell depletion, air removal efficiency, physical integrity, minimum operating volume, fill capacity, and flow path testing, Results of the tests showed that the MONOLYTH C is substantially equivalent to the predicate devices and is acceptable for its intended use.
Biocompatibility tests were performed using representative samples (whole units, subassemblies, and components) based on the intended use of the device (externalcommunicating device, circulating blood contact, limited contact duration (≤ 24 h)). Results of the tests showed that the device is biocompatible and therefore is acceptable for its intended use.
# 7. Conclusion
Based on the information provided, Sorin Biomedical Inc. concludes that the MONOLYTH C Hollow Fiber Membrane Lung with Integrated Softshell Venous Reservoir is substantially equivalent to the predicate devices and is acceptable for its intended use.

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.
