The ECC.O is intended for use in patients who undergo surgical procedures requiring extracorporeal gas exchange support and blood temperature control with a maximum blood flow rate of 5 liters/minute. ECC.O must not be used longer than 6 hours. Contact with blood for longer periods is inadvisable. ECC.O is intended for use with the Stockert Centrifugal Pump Console.
Device Story
ECC.O is an extracorporeal hemodynamic and gas exchange support system for perfusion. It integrates a hollow fiber membrane oxygenator, heat exchanger, venous air removal device (defoamer), centrifugal blood pump, and pump bracket. The system connects to a Stockert Centrifugal Pump Console. The centrifugal pump moves blood through the cardiopulmonary bypass circuit via centrifugal force; the oxygenator/heat exchanger module provides gas exchange and temperature control; the integrated defoamer separates gaseous emboli from venous blood. Used in clinical settings during surgical procedures requiring cardiopulmonary bypass. The integration of components reduces operating blood volumes during priming. Healthcare providers operate the system to maintain patient hemodynamics and gas exchange during surgery.
Clinical Evidence
Bench testing only. Testing included biocompatibility (hemolysis, cytotoxicity, irritation, acute systemic toxicity, mutagenicity) per ISO 10993-1:1995, sterility, pyrogenicity, ETO residuals, and package integrity. In vitro performance testing followed ISO 7199 and FDA guidance for oxygenators and defoamers, evaluating hemolysis/cell depletion, operating blood volume, mechanical integrity, flaking/leaching, and air handling. Results met established specifications and demonstrated equivalence to predicate devices.
Technological Characteristics
System comprises a hollow fiber oxygenator, integrated heat exchanger, venous defoamer, and centrifugal pump. Materials are identical to predicates (D 905 EOS and Ideal Mimesys). Features phosphorylcholine coating. Sterilized via ethylene oxide; nonpyrogenic fluid path; single-use. Operates via centrifugal force for blood propulsion. Designed for integration with Stockert Centrifugal Pump Console.
Indications for Use
Indicated for patients undergoing surgical procedures requiring extracorporeal gas exchange support and blood temperature control, with a maximum blood flow rate of 5 L/min. Contraindicated for use longer than 6 hours.

{1}------------------------------------------------
### INDICATION FOR USE:
The ECC.O System with Integrated Venous Air Removal, Centrifugal Blood Pump, Pump Bracket, Hollow Fiber Oxygenator and Heat Exchanger The ECC.O is intended for use in patients who undergo surgical procedures requiring extracorporeal gas exchange support and blood temperature control with a maximum blood flow rate of 5 liters/minute. ECC.O must not be used longer than 6 hours. Contact with blood for longer periods is inadvisable. ECC.O is intended for use with the Stockert Centrifugal Pump Console.
### TECHNOLOGICAL CHARACTERISTICS:
The ECC.O is comprised of a hollow fiber oxygenator with an integrated heat exchanger identical to the D 905 EOS unmodified device. The only modifications made to the device consist of a combination of the Ideal Mirnesys' Bubble Trap and Centrifugal Pump to the oxygenating module of the D 905 EOS Hollow Fiber Oxygenator with Integrated Hardshell Venous/Cardiotomy Reservoir (K043323), updating of the product specifications in the IFUs and change in the Ph.I.S.I.O. trade name. The basic function of all integrated defoamer/oxygenators is the same. The function is a combination blood gas exchange device with a dedicated active venous air removal section (defoamer). The basic function of all centrifugal pumps is the same, that is, moving blood through the cardiopulmonary bypass circuit by centrifugal force. The operating principles and fundamental scientific technology is unchanged from the unmodified The ECC.O duplicates the functionality of the separate predicate devices and the indications for use is unchanged as a result of the combination. The coating is identical to the phosphoryicholine coating used on the D 905 EOS unmodified and Ideal Mimesys' Bubble Trap and Centrifugal Pump predicate devices.
The oxygenator is ethylene oxide sterilized and has a nonpyrogenic fluid path. It is for single use only.
#### NONCLINICAL TEST RESULTS:
Applicable tests were carried out in accordance with the requirements of ISO 10993-1:1995 and the FDA May 1, 1995 Memorandum on the ISO 10993 standard for biocompatibility testing of raw materials. Tests were performed on devices accelerated aged to an equivalent of three years real time aging .- The D 905 EOS device was tested for Hemolysis, Cytotoxicity, Irritation, Acute Systemic Toxicity and Mutagenicity. The Ideal Mimesys was tested for Hemolysis, Cytotoxicity, Irritation, Acute Systemic Toxicity and Mutagenicity. Biocompatibility testing performed on D 905 EOS and Ideal Mirnesys predicate devices have been taken as reference for the ECC.O system as the raw materials used in the manufacturing process are identical to those used in both predicate devices. Sterility, Pyrogenicity, ETO residuals and package integrity testing were also conducted. The results of this testing met established specifications.
#### IN VITRO TEST RESULTS:
In vitro testing was carried out in accordance with the requirements of the "Guidance for Cardiopulmonary Bypass Oxygenators 510(k) submissions - Final Guidance for Industry and FDA Staff" issued on November 13, 2000 - "Guidance for Blood Extracorporeal Blood Circuit Defoamer 510(k) Submission" Final Guidance for industry and FDA issued on November 29, 2000 and when applicable, following the ISO 7199 standard for "cardiovascular Implants and Artificial Organs – Extra Corporeal Blood gas Exchangers (Oxygenator)" for providing the data necessary to demonstrate both the substantial equivalence with the unmodified/predicate devices and compliance with safety and effectiveness requirements. The ECC.O aged up to 3 years was tested for hemolysis/cell depletion, operating blood volume, mechanical integrity, flaking and leaching study characterization and air handling characterization. The results of these tests met established specifications. For comparative purposes the same testing, when applicable, has been conducted also on the D 905 EOS assembled in a circuit with the Ideal Mimesys' Bubble Trap and Centrifugal Pump. The modifications being made to the ECC.O do not affect the performance of the device; therefore, the functional and biocompatibility parameters exhibited by D 905 EOS apply to the ECC.O.
{2}------------------------------------------------
### CONCLUSION:
The ECC.O system is substantially equivalent to the unmodified device. Additional testing has also demonstrated the effectiveness of production techniques to assure that the oxygenator is sterile and non-pyrogenic.
Previous in-vitro data showed that the ECC.O performs in a manner substantially equivalent to the D 905 EOS with respect to the expected main performance parameters associated with ordinary oxygenators with integrated heat exchanger that is transfer of oxygen and removal of carbon dioxide, blood temperature control.
Furthermore, the ECC.O performs in a manner substantially identical to the Ideal Mimesys' Centrifuqal Pump predicate device with respect to the basic function of an ordinary centrifugal pump that is propulsion of blood through the cardiopulmonary bypass circuit by centrifugal force. In addition the ECC.O air removal system (defoamer) replaces the air removal function of ordinary venous reservoirs in a way substantially equivalent to the Ideal Mimesys' Bubble Trap with respect to the main functions of an ordinary bubble trap that is separation of gaseous emboli form the venous blood.
Data collected show that integration of the venous air removal device (defoamer) and of the centrifugal pump to the oxygenating module is advantageous in terms of lower operating blood volumes during priming procedures.
Therefore it can be concluded that ECC.O system duplicates the functionality of the separated predicate devices. Biocompatibility studies demonstrate that the device is biocompatible according to its intended use. Additional testing has also demonstrated the effectiveness of production techniques to assure that the device is sterile and non-pyrogenic.

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.
