# Device Description
Each Streamline temporary pacing lead or wire comprises a lead body with a distal and a proximal segment. The distal segment has a separate electrode. A polypropylene monofilament (PP) fixation coil (except for model 6494) extends from the distal electrode end and is attached to a small, curved needle. The curved needle creates a channel in the myocardium for embedding the electrode. The PP fixation coil provides a means of securing the electrode in place. The proximal lead body terminates into a chest needle used to penetrate the chest wall, followed by pulling the proximal portion of the lead through the chest. The device is supplied sterile and intended for single use only.
# Principle of Operation
Arrhythmias can occur following cardiac surgery. When a patient's not in sinus rhythm, cardiac output is not optimal, putting the patient's life at risk.
All temporary pacing leads are intended for temporary atrial and/or ventricular pacing and sensing for a contemplated implant duration of 7 days or fewer. They are designed to pace and sense the heart during and after cardiac surgery compatible with Medtronic's external pacing systems (EPG).
# Description of Change
This Special 510(K) aims to notify the FDA of the language related to the Magnetic Resonance Imaging (MRI) condition added to the IFU. All models of the Streamline family products were tested in a nonclinical environment and deemed MR Conditional. Other changes were made to the IFU, which entailed rewording the Indication for Use, Contraindications, and Warnings, with no change to the intent.
# Indication for Use
Streamline temporary leads and wires treat an irregular heartbeat during or after cardiac surgery by providing electrical stimulation to the heart.
- Models 6491, 6494, 6495, and 6500 are intended for atrial and ventricular use. ●
- Model 6492 is intended for atrial use only. .
- . Model 6491 and Model 6492 have smaller chest fixation coils and are appropriate for use in thin heart tissue and, in the case of Model 6491, a smaller chest cavity (for example, in a pediatric patient).
# Contraindications
There are no known general contraindications to temporary postsurgical pacing. The cardiac surgeon determines the pacing system to be used on the patient medical condition and anatomy
# Comparison to Predicate Devices
Streamline Temporary Pacing Leads and wire have the following similarities to the predicate devices that have received FDA clearance: K190716 and K171253.
- . Same intended use/indications for all devices in scope
- The same finished device operating principle for all devices in scope
- All Models are packaged using the same materials and sterilized via EtO.
{6}------------------------------------------------
# Summary of Testing
Each Streamline Model was tested in two configurations bundled and extended and assessed as follows:
- RF Heat assessment per ASTMF2192-19e2 at 64MHz (1.5T) and at 123MHz (3T) .
- . Force and Torques in a 3.0 T GE Discovery MR750 whole-body MR system per test method described in ASTM F2052-15w
- Imaging artifact assessment was not tested as it was determined that only the head ● and lower extremities may be imaged therefore, there is limited to no risk of the lead to cause image artifacts in the scans.
# Conclusion
The nonclinical MRI testing and calculations support that the Streamline family of products is MR Conditional and can be scanned safely under the following conditions:
The following table is included in the IFU.
#### Magnetic Resonance Imaging (MRI) safety information
Image /page/6/Picture/9 description: The image shows a black triangle with the letters "MR" in bold black font inside of it. The triangle is equilateral and the letters are centered within the triangle. The image is simple and the contrast between the black triangle and the white background makes it easy to see.
A patient with a Medtronic Streamline pacing lead or wire may be safely scanned under the following conditions. Failure to follow these conditions may result in injury to the patient.

| Additional instructions or information essential for safe use in the MR environment | Before an MR exam, disconnect the connector pin from the pulse generator. The pulse generator is unsafe in a MR environment. MR exams are contraindicated for patients who remain dependent on pacing.<br>When a patient undergoes an MR scan, the connector pins must be inserted into the pin protectors (Chapter 6, step 6c), with the excess lead coiled. The pin protectors and the coiled lead must be taped to an area of the patient's skin (Chapter 6, step 7), such as to the patient's chest. |

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.
