## Device Description
hipEOS 3.0 allows surgeons to perform preoperative surgical planning of hip surgeries in case of Total Hip Arthroplasty (THA). The software provides surgical tools for the implantation of a Total Hip Prosthesis. This software can be used to plan interventions using implants from different manufacturers. The images displayed are x-rays from EOS System (EOS Imaging) and 3D model of the hip from sterEOS Workstation (EOS Imaging), hipEOS also displays preoperative parameters and updated values of parameters after planning. It exports a planning report containing the planning parameters: model, size and position of implants. hipEOS is accessible on any computer via ONEFIT Management System (Class I device -Product code LMD - 510(k) Exempt) that provides a secure internet interface and storage through authentication mechanisms.
## Intended Use / Indications for Use

measurements on the image or 3D model of bones and for selecting and positioning the hip implant models. Clinical judgments and experience are required to properly use the software.
# Comparison of Technological Characteristics with the predicate devices
Preoperative planning for hip surgery is the technological principle for both hipEOS and its predicate devices. The aim for these software is to provide to the surgeon realistic tools for performing the preoperative planning of hip surgeries.
At a high level, the subject and its predicate devices are based on the following same technological elements:
- Access to the software is limited only to surgeons because surgical experience is required. -
- Use of 2D images and 3D model of the hip. -
- -Use of the workflow to guide the surgeon through the steps of planning: observation, analysis and action.
- An interface that allows for the maximum amount of information (including images) and tools, visible simultaneously on the same page.
- -Display values of preoperative parameters and updated values after planning.
The following technological differences exist between the subject and its predicate devices:
- (1) Use of seated patient images, if available
They are optional in hipEOS 3.0 and they can be used to provide more information to the surgeon (ROM simulation in sitting and theoretical sitting). This difference does not raise new questions of safety or performance for hipEOS 3.0 because this type of imagery was already used by the primary predicate.
- (2) Workflow available
The appearance of steps in hipEOS 3.0 is related to the decomposition of the planning to ensure that the user will not confuse the preoperative information with those from the planning and also to simplify the interface by minimizing the information present at each step. This difference does not raise new questions of safety or performance for hipEOS 3.0 because the user still has the same information at his disposal.
- (3) The range of motion simulation
This type of analysis tool has already been integrated with planning software for total hip arthroplasty (predicate 2). Although the range of motion of the predicate 2 and the one of the submitted device are different, it does not raise new questions of safety or performance for hipEOS 3.0: the ROM of hipEOS 3.0 allows to evaluate for each planning the risk of collision between the components of the implant. This feature is only based on objects of which the 3D geometry is accurate.
- (4) The generation of a second planning report, in DICOM format
This difference does not raise new questions of safety or performance for hipEOS 3.0 because the information in the planning report was already provided to the user and the chosen format is universal.

# Performance Data
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". The software was considered as a "moderate" level of concern, since a failure or latent design flaw could directly result in minor injury to the patient or operator, or could indirectly result in minor injury to the patient or operator through incorrect or delayed information or through the action of a care provider.
# Conclusions
The device has the same intended use, and similar indications for use, technological characteristics, and principles of operation as its predicate device. The minor differences between the device and its predicate device raise no new issues of safety or effectiveness. Performance data demonstrate that the hipEOS 3.0 is as safe and effective as its predicates hipEOS 2.5 (K161479) and DYONICS PLAN Hip Impingement Planning System (K132636) and, thus, is substantially equivalent.

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.
