#### IV. Product Description:
The predicate device in this submission is an accessory to the main predicate devices listed, and is covered under those device registrations. Individual device listings for the accessory footswitch and hand switches were not found for the predicate devices listed. One wireless footswitch classification was found in an unrelated but parallel classification. That was the Iridex Wireless Footswitch (K062074) for ophthalmic lasers, Classification Product Code HQF, Regulation number 886.4390.
The common footswitch or hand switch of the predicate device is comprised of a set of switches connected to a base that send signals through a cable to the main x-ray generator. Signals sent typically are fluoroscopy or x-ray exposure commands, or other simplified configuration commands such as lights on or off, last image hold, etc. These signals are simple "on/off" analog signals, usually less than 24 VDC, and are interpreted by the predicate device to perform its function. The disadvantage to the common footswitch or hand switch is the cable that attaches them to the predicate device. These cables become a trip hazard to personnel because they lay on the floor or on other spaces. They are also a contamination hazard and are difficult to clean. Because these cables are flexed continually, cable breakage is common, creating maintenance and equipment performance problems.
The Spectre System is an alternate option to the existing cabled foot switch and hand switch for users of Xray systems. It consists of three parts-a footswitch/transmitter, a hands switch/transmitter, and a receiver. The Spectre system receiver connects to the x-ray system through the same connector as the current footswitch, and operates the x-ray system by exactly emulating the functionality of the current cabled footswitch and hand switch. There are no cables, therefore, no trip hazards, contamination hazards, or cable breakage hazards. The footswitch and hand switch are powered by batteries, eliminating shock hazards. The receiver is mounted on the predicate device, and is powered from the predicate device.
#### V. Indications for Use:
The Spectre System is intended for use with compatible diagnostic x-ray systems in hospital or outpatient facilities. The Spectre System is indicated for use as an accessory to provide input control to compatible xray systems. This accessory includes a wireless footswitch, a hand switch, and a receiver. It is cleared for use only for the particular indications of the X-ray system to which it is attached. Attachment to any other device other than the predicate device it is designed for may result in damage to the Spectre system or to the connected device.
#### VI. Rationale for Substantial Equivalence
Non clinical testing in our facility included the installation of the Spectre system onto the predicate devices listed, and conducting functional testing of the Spectre system to insure exact functional performance as compared to the predicate footswitch and hand switches. Test results showed in each individual condition that the Spectre system performed identically to the predicate devices. 100 iterations of each possible signal configuration were tested. There were no malfunctions noted during the tests. Long term testing using the Spectre system over a period of weeks also produced reliable functionality results from the system. During these tests, no malfunction was recorded.
The Spectre System shares the same indications for use, device operation, and overall technical and functional capabilities of all cabled footswitches and hand switches used by the predicate devices. It is therefore substantially equivalent to the predicate devices:

#### VII. Safety and Effectiveness Information
The purpose for using the Spectre wireless encrypted Footswitch and Hand Switch System is to increase the safety of patients by elimination the contamination hazards of cables as well as improving the overall performance record of the predicate device, thus making it a safer device by eliminating the cables. This system also increases the safety and efficiency of the medical personnel by allowing the cable free "trip free" workspace provided by the wireless system.
Non clinical functional testing showed complete functionality of the system without error. Significant studies done by independent sources (shown in section 18) have demonstrated the safety, efficiency and reliability of wireless systems in the medical environment. All components are UL listed for Medical use, and are therefore tested and demonstrated to be as safe in the medical environment as the predicate devise. The review of the indications for use and technical characteristics provided demonstrates that the Spectre system is substantially equivalent to the predicate devices.
#### VIII. Conformance to Standards
All design, testing, manufacturing and documentation was performed in conformance with IEC 60601-1, Medical Electrical Equipment-Part 1: General Requirements for Safety, 1988; amendment 1, 1991-11; amendment 2, 1995 (General). Independent testing was conducted by Underwriter's Laboratories, Inc. for compliance to the above mentioned standard. The complete report is included in section 18 of this submission. These tests concluded that this system complies and conforms to all applicable sections of this standard.
Additional testing by an independent Laboratory demonstrates compliance to the following standards: IEC 60601-1-2 Medical Device (ed 2.1) (2004) which includes IEC 61000-4-2(ed 1.2) 2001. IEC 61000-4-3 (ed 3) 2006, IEC 61000-4-4(ed 2) 2004, IEC 61000-4-5(ed 1.1) 2001, IEC 61000-4-6(ed 2) 2003, and IEC 61000-4-11(ed 2) 2004. Also included in that testing was compliance to EN Emissions Class B for Radiated Emissions(1998) and Conducted Emissions (1998). The complete testing is found in section 18. These tests concluded that the Spectre System is in conformance to FCC Standards, and all applicable sections of IEC 60606-1-1-2 Medical Device (ed 2.1) 2004.
#### IX. Conclusion
The Spectre System was designed and manufactured to be a replacement for the cabled devices used with the predicate devices. Internal testing shows it performs the exact same tasks, but simply uses proven new technologies to eliminate the need for hazardous cabling. It is substantially equivalent to the predicate devices in similar indications of use, similar design and functional features with, and thus is substantially equivalent to, the predicate devices. Independent testing conformance to all applicable standards.

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.
