The angiographic X-ray systems are indicated for use for patients from newborn to geriatric in generating fluoroscopic and rotational images of human anatomy for cardiovascular, vascular and non-vascular, diagnostic and interventional procedures. Additionally, with the OR table, the angiographic X-ray systems are indicated for use in generating fluoroscopic and rotational images of human anatomy for image-guided surgical procedures. The OR table is suitable for interventional and surgical procedures.
Device Story
Interventional X-ray systems (Innova IGS 5/6, Discovery IGS 7/7 OR) perform monoplane/biplane fluoroscopic imaging for minimally invasive procedures. System components include C-arm positioner, X-ray tube, power unit, digital detector, and image processing unit. Discovery IGS 7 OR integrates with third-party neurosurgical head holders (skull clamps) and OR tables. Device modifications include: 1) Enhanced collision avoidance software allowing operators to define guard volumes around skull clamps/patient head to prevent gantry/table collisions during movement; 2) Optional wireless footswitch (2.4 GHz proprietary protocol) for X-ray control and table brake release. Used in hybrid ORs or interventional suites by physicians/surgeons. Output is real-time fluoroscopic/rotational imagery used for procedural guidance. Benefits include reduced cable clutter and improved safety during complex neurosurgical/trauma procedures via collision mitigation.
Clinical Evidence
No clinical studies were required. Substantial equivalence supported by bench testing, simulated use testing, and usability validation. Verification confirmed design outputs met inputs for collision avoidance and wireless functionality. Safety testing included EMC and coexistence testing per FDA wireless guidance and conformance to IEC 60601-2-43, IEC 62304, and IEC 62366.
Technological Characteristics
System includes C-arm positioner, digital detector (up to 41cm), X-ray tube, and power unit. Connectivity: Wired or optional 2.4 GHz wireless footswitch. Software: Collision avoidance model with operator-defined guard volumes. Standards: 21 CFR 1020.30/32, IEC 60601-2-43:2010, IEC 62304 (2006), IEC 62366 (2007).

| The purpose of this Premarket Notification is for 2 changes:<br>First, a change of the collision management of Discovery™ IGS 7 OR to enable the use of a Neurosurgical head holder (skull clamp). During trauma neck surgery and stereotactic navigation, a gantry collision with the skull clamp could result in patient harm, delayed or halted surgical procedures. The subject of this submission is to introduce a functionality for adapting the collision avoidance model to the geometrical characteristic of the skull clamp and patient position with a guard volume defined and validated by the operator during the procedure preparation phase. During the procedure, the collision avoidance software will slow down and stop gantry and/or table axis to minimize risk of collision of a motorized moving part with the patient head or the skull clamp. In this configuration, the OR table, the Neurosurgical head holder and its support are from third party Medical device manufacturers. As a consequence, there is no mechanical interfaces between these devices and the Discovery™ 7 OR. Those devices are registered and cleared in the US. The Neurosurgical head holder is from Pro Med Instrument manufacturer (K063494). The OR table is the registered Magnus OR |
{6}------------------------------------------------
Image /page/6/Picture/0 description: The image shows the General Electric (GE) logo. The logo consists of the letters 'GE' intertwined within a circle. The circle and the letters are blue, and there are white flourishes around the circle.
| | The second change is for a primary technology change, adding an<br>optional wireless footswitch in the examination room to Innova™<br>IGS 5, Innova™ IGS 6, Discovery™ IGS 7 and Discovery™ IGS 7 OR. It<br>provides identical functionalities as the wired footswitch for the<br>control of X-ray on and off, and for the control of the table top brake<br>release.<br>Labelling is updated for the enhanced collision management for the<br>use with Neurosurgical head holder and for the wireless footswitch. |

| Intended Use: | The angiographic X-ray systems are indicated for use for patients<br>from newborn to geriatric in generating fluoroscopic and rotational<br>images of human anatomy for cardiovascular, vascular and non-<br>vascular, diagnostic and interventional procedures.<br>Additionally, with the OR table, the angiographic X-ray systems are<br>indicated for use in generating fluoroscopic and rotational images<br>of human anatomy for image-guided surgical procedures. |
| | The OR table is suitable for interventional and surgical procedures. |
| Indication for Use: | The angiographic X-ray systems are indicated for use for patients<br>from newborn to geriatric in generating fluoroscopic and rotational<br>images of human anatomy for cardiovascular, vascular and non-<br>vascular, diagnostic and interventional procedures.<br>Additionally, with the OR table, the angiographic X-ray systems are<br>indicated for use in generating fluoroscopic and rotational images<br>of human anatomy for image-guided surgical procedures.<br>The OR table is suitable for interventional and surgical procedures. |
| Technology: | The modified GE Healthcare IGS Interventional X-Ray systems<br>employ the same fundamental scientific technology as the<br>unmodified predicate devices.<br>The change to enable the dynamic adaptation of the collision<br>avoidance model with a model fitted to the needs of the operator<br>and of the procedure, is a software change. The collision avoidance<br>software is the same as with the predicate devices. The change is<br>the dynamic adaptation of the collision avoidance model. All causes<br>of hazard relative to the use of a Neurosurgical head holder in<br>combination with the Discovery™ IGS 7 OR have been identified and<br>mitigated.<br>The optional wireless footswitch consists of a footswitch containing<br>a transmitter system, a receiver that is installed near the connection<br>plug of the wired footswitch (at the table base of the Innova-IQ<br>table, of the Omega table or at the Discovery Control Center table<br>side cart), and a charger. The introduction of this wireless footswitch<br>does not change existing electrical or software interface of the<br>predicate devices. The new option is equivalent to the wired<br>footswitch on the predicate in that the functionalities are identical.<br>The communication between the footswitch emitter and the |
| | receiver is performed via a proprietary protocol using 2.4 GHz radio<br>frequency technology.<br>The wireless option provides placement flexibility and reduces cable<br>clutter.<br>Both changes have no impact on x-ray imaging performance.<br>The intended use and indications for use remain unchanged from<br>those of the predicate devices. The expansion to x-ray<br>interventional, minimally invasive surgery and conventional open<br>surgery procedures requiring the use of a neurosurgical holder in<br>combination with Discovery™ IGS 7 OR is included in Discovery IGS<br>7 OR's indications for use of interventional, image-guided surgical<br>and surgical procedures. |
| Determination of Substantial<br>Equivalence: | The modifications to Discovery™ IGS 7 OR collision management<br>software and to IGS interventional x-ray systems for the wireless<br>footswitch were developed under the GE Healthcare's design<br>controls processes and overall quality management system. |
| | IGS interventional x-ray systems conform to 21CFR 1020.30 and 32,<br>and with voluntary standards IEC 60601-2-43:2010, IEC 62304<br>(2006) and IEC 62366 (2007). |
| | Risk management activities using risk analysis to identify any<br>potential issues incorporating the wireless footswitch and the use of<br>a skull clamp were performed. These issues were assessed and<br>mitigated. |
| | The following testing was used to assess safety and effectiveness<br>and, thus, to establish the substantial equivalence with the<br>predicate devices. |
| | Summary of Non-Clinical Tests:<br>The following quality management measures were applied to the<br>development of these modifications:<br>Simulated Use Testing ensured the system conforms to user<br>needs and intended uses through simulated clinical<br>workflow using step-by step procedures that would be<br>performed for representative clinical applications. Usability validation testing was conducted to confirm that<br>the product can be used safely and effectively. Participants<br>were representatives of actual users, with knowledge of the<br>customer needs and clinical applications. Product verification ensured the system conforms to its<br>requirements including hazard mitigations risk<br>management requirements. The verification tests<br>confirmed that design output meet design input<br>requirements. Tests were executed at component, software<br>subsystems and system levels. |
| | Safety testing were performed to confirm that the product<br>meets the requirements of the aforementioned standards.<br>It includes the EMC and coexistence testing per the "Radio<br>Frequency Wireless Technology in Medical Devices"<br>Guidance for Industry and Food and Drug Administration<br>Staff issued on August 14, 2013 (Wireless Guidance). |
| | Summary of Clinical Tests:<br>The subject of this premarket submission, change to Discovery™ IGS<br>7 OR collision management to enable the use of a neurosurgical<br>head holder and the change to add an optional wireless footswitch<br>in the examination room to GE Healthcare interventional x-ray<br>systems did not require clinical studies to support substantial<br>equivalence. The expansion to x-ray and surgical procedures<br>requiring the use of a neurosurgical holder in combination with<br>Discovery™ IGS 7 OR is included in Discovery IGS 7 OR's indications<br>for use of image-guided surgical and surgical procedures. It does not<br>introduce new indications for use. Substantial equivalence relies on<br>clinical information that is pre-existing on the cleared predicate<br>devices.<br>Design verification and validation testing were performed to<br>confirm that the safety and effectiveness of the devices has not |
| | been affected. The test plans and results have been executed with<br>acceptable results. |
| Conclusion: | GE Healthcare considers that the Discovery™ IGS 7 OR incorporating<br>the enhanced collision management for the use of a skull clamp or<br>that a GE Healthcare IGS interventional x-ray system incorporating<br>the optional wireless footswitch to be as safe and as effective and<br>substantially equivalent to the predicate devices.<br>This conclusion is based on the fact that Discovery™ IGS 7 OR<br>incorporating the collision management optimization for the use in<br>combination with the Neurosurgical head holder and that GE<br>Healthcare interventional x-ray systems incorporating the optional<br>wireless footswitch have: the same indications for use as their predicate devices. The modified devices have the same technological<br>characteristics as their predicate devices. Verification and Validation testing has demonstrated that<br>the design inputs, user requirements, and risk mitigations<br>have been met. Engineering bench testing per the FDA guidance Radio<br>frequency wireless technology in medical devices as well as<br>conformance to IEC standards and guidance documents<br>were provided. |
| | The successful completion of the above testing was sufficient to assess safety and effectiveness and, thus, to establish the substantial equivalence. |

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.
