Indications for Use
The intended use for Medela's Basic and Dominant Flex Suction Pumps is to provide a vacuum source for use during surgery.
Device Story
Basic and Dominant Flex are high-vacuum, high-flow, AC-powered suction pumps for hospital, ambulatory, and clinical use. Devices utilize a piston and cylinder system for suction; a microcontroller manages motor speed and user interface. Users (physicians/nurses) operate the device via front-panel controls, including a vacuum gauge, regulator knob, and capacitive 'CleanTouch' sensors for power and flow selection (Dominant Flex). A 'Safety Set' (jar, lid, float) prevents pump overflow. Output is a regulated vacuum source used to aspirate fluids/tissues or provide suction for external cardiac stabilizers and ablation probes. The device benefits patients by providing reliable, rapid vacuum for surgical and bedside procedures.
Clinical Evidence
No clinical data. Bench testing only. Performance verified through comparative testing against predicate devices using various media (sterile water, apple sauce, solidifier mix) to simulate surgical fluids. Compatibility testing with cardiac stabilizers and ablation probes confirmed vacuum maintenance at specified levels (-600 mmHg, -250 mmHg, -400 mmHg) over 8-hour durations.
Technological Characteristics
AC-powered piston and cylinder suction pump. Features include vacuum gauge, regulator knob, and capacitive sensors. Connectivity: Standalone. Materials: Not specified. Sterilization: Not specified. Software: Microcontroller-based control of motor speed and user interface. Electrical safety/EMC compliance per IEC 60601-1-2:2007.
Indications for Use
Indicated for vacuum extraction, aspiration during flexible endoscopy, and aspiration/removal of surgical fluids, tissue (including bone), gases, bodily fluids, or infectious materials from wounds, patient airways, or respiratory support systems during surgery or at the bedside. Dominant Flex is also indicated for aesthetic body contouring. Both pumps are indicated to provide vacuum for cardiac tissue stabilizers used in off-pump coronary artery bypass and for epicardial ablation probes.

#### INTENDED USE:
The intended use for Medela's Basic and Dominant Flex Suction Pumps is to provide a vacuum source for use during surgery.
#### INDICATIONS FOR USE:
The Basic Suction Pump is indicated for vacuum extraction, aspiration during flexible endoscopy, and aspiration and removal of surgical fluids, tissue (including bone), gases, bodily fluids or infectious materials from wounds or from a patient's airway or respiratory support system either during surgery or at the bedside. The Basic Pump can also be used to provide the vacuum required for use with cardiac tissue stabilizers used in off-pump coronary artery bypass and for use with epicardial ablation probes.
The Dominant Flex Suction Pump is indicated for vacuum extraction, aesthetic body contouring, aspiration during flexible endoscopy, and aspiration and removal of surgical fluids, tissue (including bone), gases, bodily fluids or infectious materials from wounds or from a patient's airway or respiratory support system either during surgery or at the bedside. The Dominant Flex Pump can also be used to provide the vacuum required for use with cardiac tissue stabilizers used in off-pump coronary artery bypass and for use with epicardial ablation probes.
#### DETERMINATION OF SUBSTANTIAL EQUIVALENCE:
#### SUMMARY OF TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICE
The labeling of the Basic and Dominant Flex has been revised to include the following new indications: aesthetic body contouring (Dominant Flex only) and to provide the vacuum required for use with cardiac tissue stabilizers used in off-pump coronary artery bypass and for use with epicardial ablation probes. The Basic and Dominant Flex Suction Pumps are compared to the previously cleared versions (K130123, main predicate) as well as to the Medela Dominant 50 for aesthetic body contouring (K063336), the Estech Cobra Surgical Systems for the new indication to provide a vacuum source during epicardial ablation (K051749) and the Medtronic Octopus Evolution AS 2010 and Urcin Evo 2020 Tissue Stabilizers (Class 1) to provide vacuum during off-pump coronary artery bypass.
The Basic and Dominant Flex only are providing a vacuum source that is used with ablation probes such asthe Estech System and with cardiac tissue stabilizers such as the Medtronic

stabilizers. The ablation probes and stabilizers do not provide vacuum, but the labelling, specifies the use of an operating room suction source.
The Dominant Flex has equivalent specifications to the Dominant 50 Lipo (K063336) for the aesthetic body contouring indication. The Dominant Flex operates at 0.16 horsepower (hp) which provides equivalent performance to the Dominant 50 Lipo which operates at 0.2 hp.
The Basic and Dominant Flex Suction Pumps use identical technology as the Basic and Dominant Flex Suction Pumps cleared in K130123.
#### SUMMARY OF NON-CLINICAL TESTS:
The Basic and Dominant Flex Suction pumps comply with voluntary standards for electrical safety, electromagnetic compatibility, and safety of electrically powered suction pumps. The changes to the product labeling for new indications for use did not impact compliance to standards as compared to the pumps cleared in K130123. Non-significant changes made to the Basic and Dominant Flex Suction Pumps since the original clearance were also described. One of these changes affected electromagnetic compatibility and therefore testing to IEC 60601-1-2:2007 was completed.
For the new indications for the Basic and Dominant Flex Suction Pumps, Medela AG has completed bench testing to demonstrate the performance of the pumps in the new applications.
For use for the indication of aesthetic body contouring, a comparison was made between the predicate Dominant 50 Lipo (cleared for aesthetic body contouring (K063336)) with the Dominant Flex to show their equivalence. Then the Dominant Flex was also compared to the HK Liposuction Aspirator Model AP-III which is also cleared for the indication of aesthetic body contouring (K032802). Testing showed equivalent free air flow, vacuum build up, and suctioning capacity of fluids with varying consistencies, including with various cannulas. The density of body fat varies due to the area suctioned and the technique. Sterile water, apple sauce and solidifier mix were used in the testing.
Testing was performed to demonstrate the compatibility of Basic and Dominant Flex in combination with epicardial ablation probes. Testing was conducted with the Estech Cobra Fusion Ablation System (bipolar or monopolar) and demonstrated that when the pump is running the vacuum is maintained at -600 mmHg ± 10%.
Testing was performed to demonstrate the compatibility of Basic and Dominant Flex in combination with cardiac tissue stabilizers used in off-pump coronary artery bypass (OPCAB). Testing was conducted with the Medtronic Octopus Evolution and Urchin Evo Positioners. The test results demonstrate that when the pump is running, the vacuum is maintained at settings of -250 or -400 mmHg for up to 8 hours.
{8}------------------------------------------------
#### Medela AG Basic and Dominant Flex Suction Pumps
#### SUMMARY OF CLINICAL TESTS:
The Basic and Dominant Flex Suction Pumps have not been the subject of clinical testing.
#### CONCLUSION:
The new indications for use do not change the intended use of the pump, to provide a vacuum source for use during surgery, and do not raise new issues of safety and effectiveness as compared to the main predicate device, cleared in K130123. Verification and Validation testing demonstrated that no adverse effects have been introduced by these differences and that the device performs as intended.
From the results of nonclinical testing described, Medela AG concludes that the Basic and Dominant Flex are substantially equivalent to the legally marketed predicate device.

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.
