#### Date Prepared:

#### Device Description:
The Surgeon Controlled Arm for the Levita Magnetic Surgical System (MSS) comprises two collaborative surgeon-controlled arms, which along with their controllers, control software, and custom attachments, are intended to hold and control the Magnetic Controller of the commercially available MSS (most recently cleared under K191762) using an arm and to hold and control a commercially available endoscope with camera using the second arm. The design of the surgeon-controlled arms, referred to as the Scope Arm and the Magnet Arm, includes several redundant safety features that make them well suited for use with the MSS in the operating room environment, including hardware and software safety controls.
{4}------------------------------------------------
#### K223673
When mounted on the Scope Arm, an endoscope can be pivoted and translated as controlled by the user, while maintaining minimal motion at the point where the endoscope enters the patient's body via a standard trocar. Similarly, when mounted on the Magnet Arm, the Magnetic Controller can be moved to different positions on or away from the abdominal wall.
The Surgeon Controlled Arm includes the following components:
- (1) Two Carts, which are the Scope Cart and the Magnet Cart. Each Cart includes a surgeoncontrolled arm mounted on top of a moveable cart with custom attachments. One arm functions as a Scope Arm to hold a commercially available endoscope with endoscopic camera. The other arm functions as a Magnet Arm and includes a Magnet Holder to hold the Magnetic Controller of the MSS;
- (2) a Scope Holder for attachment and detachment of a compatible commercially-available endoscope to the end of the Scope Arm:
- (3) a Foot Controller for foot-actuated selection of the active arm and foot-actuated remote control for one of the arms at a time;
- (4) custom-programmed software, the Levita Custom Control Software Program.
The Surgeon Controlled Arm provides for computer control of a dual- arm device with motorized axes to hold and control the movements of a rigid endoscope and the Magnetic Controller of the Levita MSS during the minimally-invasive procedures cleared for the MSS (most recently cleared under K191762). The user selects the active arm and controls its movement using a Foot Controller. Only one arm is enabled for computer-controlled movement at any given time; while one arm is being moved, the other arm remains stationary. The user may also manually move the arms (i.e. hand guiding) at any time without the use of the Foot Controller.
For the Scope Arm, the reference point for scope movement is established as the Trocar Point and is set by the user, who positions the endoscope near the trocar inserted in the body opening (e.g. the abdominal fascial layer) and presses the Teach Trocar button on the Scope Adaptor. The Custom Control Software Program then calculates the required individual movements of the Scope Arm motorized axes relative to the Trocar Point in order to achieve the desired total movement of the endoscope with respect to the endoscope view. Once the Custom Control Software Program completes the Teach Trocar procedure, the Foot Controller is enabled, allowing the user in a standing position by the operating table to direct endoscope movement by using their foot to press on switches corresponding to the allowed movement directions.
For the Magnet Arm, the same arm hardware, software, and Foot Controller are employed to move the Magnetic Controller also in the same directions.
#### Indications for Use:
The Surgeon Controlled Arm is indicated for use to hold and position a rigid laparoscope/endoscope and the Magnetic Controller of the Levita Magnetic Surgical System in
{5}------------------------------------------------
minimally invasive interventions where the Levita Magnetic Surgical System is indicated for use.
### Comparison of Intended Use and Technological Characteristics with the Predicate Device:
The subject and predicate devices have the same intended use. Both devices are surgeoncontrolled computer-driven systems whose function is to hold and position a rigid laparoscope/ endoscope. The subject device is only indicated for use with the Levita Magnetics Surgical System (most recently cleared under K191762).
The technological characteristics of the subject device and predicate device are substantially equivalent. Both devices have the same principles of operation using similar components: they provide software-based control of surgeon-controlled arm device(s) with motorized axes to hold and move a rigid commercially-available endoscope during minimally-invasive procedures. The user drives the electrically-powered device using a remote controller. The starting point of the movement for each case is saved as the trocar point from which the software calculates the required individual movements of the device arm's motorized axes to achieve the desired total movement. The user may also move the arm by hand guiding, without use of the remote controller. Neither predicate nor subject device interacts directly with any intra-cavity organ, but instead, holds instruments externally.
The following are differences in technological characteristics:
- . Both devices include a surgeon-controlled arm for controlling a rigid commerciallyavailable endoscope. The subject device additionally includes a second, similar arm for controlling the Levita Magnetics Magnetic Controller component of the Levita Magnetics Surgical System
- . The predicate device remote controller is controlled by hand and the subject device remote controller is controlled by foot.
- The subject device additionally includes a switch to allow the surgeon to determine the . active arm for remote control.
- The arm motion control specifications for the subject device, i.e. maximum velocities ● and acceleration, latency, range of motion, and safety limits, may differ from those of the predicate device, which are unknown.
## Performance Data:
The following performance data were provided to demonstrate safety and effectiveness in support of substantial equivalence determination:
- Electrical safety and electromagnetic compatibility (EMC) performed to applicable . requirements of IEC 60601-1 and IEC 60601-1-2.
- Software Verification and Validation Testing were conducted and documentation was . provided as recommended by FDA guidance document. "Guidance for the Content of

## Summary:
{7}------------------------------------------------
#### K223673
The Surgeon Controlled Arm has the same intended use as the predicate device. In addition, it has similar technological characteristics; performance data demonstrates that any differences in technological characteristics do not raise different questions of safety or effectiveness. Therefore, the Surgeon Controlled Arm is substantially equivalent to the cleared predicate device.

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.
