# SECTION 5 510(k) SUMMARY
## Generic/Common Name:
Stereotaxic Instrument
# PREDICATE DEVICES
The ARTASTM System is substantially equivalent to the following predicate device:
- ARTASTM System, K103428 .
## INDICATIONS FOR USE
The ARTAS" System from Restoration Robotics is indicated for harvesting hair follicles from the scalp in men diagnosed with androgenic alopecia (male pattern hair loss) who have black or brown straight hair. The ARTAS" System from Restoration Robotics is intended to assist physicians in identifying and extracting hair follicular units from the scalp during hair transplantation.
## PRODUCT DESCRIPTION
The ARTASTM System implements the manual Follicular Unit Extraction (FUE) approach to harvesting follicular units. The ARTAS™ System is used, under the direction of a physician, to automate the manual FUE technique. The ARTAS™ System is positioned over the patient's scalp by the physician and follicular units are identified.
Follicular units are then harvested from the patient's scalp. The follicular units are stored until they are implanted into the patient's scalp by the physician or technician using current manual implantation techniques.
The ARTASTM System is an interactive, image-guided, computer-assisted system consisting of seven main subsystems;
- 1. Robotic Arm Subsystem
- 2. Imaging Subsystem
- 3. Needle Mechanism
- 4. Safety Subsystem
- 5. Computer
- 6. Accessory Kits (Disposable and Reusable)
- 7. Patient Chair
These main subsystems, with the exception of the Accessory Kits and Patient Chair, are housed on or within a Control Cart.
#### TECHNOLOGICAL CHARACTERISTICS
The predicate ARTASTM System provided left and right screen views on the monitor during the harvesting procedure. The left screen provided a view of the current follicle bcing harvested and the right screen a view of the next follicle selected for harvest. The present modified ARTASTM System provides a single, larger view of the follicle being harvested and a map view of the entire field of harvest.
{2}------------------------------------------------
## SECTION 5 510(k) SUMMARY
The predicate ARTASTM System that was cleared by FDA in April 2011, (K103428) required harvesting parameters to be manually entered by the user by keying in numbers using a PC keyboard. The present system that is the basis of this submission incorporates toggle arrows for processing parameters on the computer monitor allowing a much simpler means by which to vary these parameters. This improvement in ease of use was validated clinically.
The modified ARTASTM System has been productized for cost reduction and manufacturability resulting in a system that is much more mobile than the predicate ARTASTM System. The improvements made in the system mobility along with the mechanism changes were validated clinically.
## Auto Hair Selection
The predicate ARTASTM System followed a harvesting process in which the system would move after completing a harvest and then highlight the next follicle for harvest. The present modified ARTASTM System highlights the next follicle for harvest while harvesting the initial follicle.
The predicate ARTASTM System required the user to adjust the direction of harvest for subsequent harvests once the needle completed a grid row. The present modified system recognizes the end of a row and changes direction automatically although, the user can still change the direction at any time. This change was made possible by incorporating fiducial markers on the skin tensioner that is applied to the patient scalp. This change improves the ease of use and was validated clinically.
#### Disposable Kit
Several changes in the disposables have been implemented in the present modiffed version of the ARTASTM System from the disposables included for the predicate system. The disposables used with the predicate ARTASTM System were provided non-sterile with instructions on how to sterilize the disposables using an autoclaye. The present disposable kit included with the modified ARTASTM System is provided gamma sterilized. This process has been validated in accordance with ANSI/AAMI/ISO 11137 and 11737 standards.
The change to provide the disposable kit sterile in the modified ARTASTM System submission requires that the present disposable kit bear a "Use By Date" that ensures sterility for a minimum of one (1) year. This shelf life was validated in accordance with ASTM F1980-07.
A design change was made to the punch used in the modified ARTASTM System resulting in a more reliable punch. This change was validated clinically.

## SECTION 5 510(k) SUMMARY
#### NONCLINICAL TEST SUMMARY
Extensive testing was performed on the subject device to support a determination of substantial equivalence to the predicate device. This testing included software verification and validation, patient chair verification, system cart verification, and disposable and reusable verification. All required electrical safety tests including EMC (IEC-60601-1 and IEC60601-1-2) were also performed. Biocompatibility testing was performed on all patient contacting materials for the disposable and reusable components.
The testing referenced above includes all of the tests that were performed on the predicate device. Since the results were identical for these tests, substantial equivalence has been demonstrated through these nonclinical tests.
# CLINICAL TEST SUMMARY
A clinical study was performed on ninety-two (92) patients using the modified ARTASTM System. Primary efficacy (transection rates and non-implantable follicles) as well as safety endpoints were met.
#### SUBSTANTIAL EQUIVALENCE
The indications for use for the modified ARTASTM System is substantially equivalent to the indications for use of the predicate ARTAS™ System (K103428). Any differences in the technological characteristics between the devices do not raise any new issues of safety or efficacy. Thus, the modified ARTASTM System is substantially equivalent to the predicate device.
## TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION
All necessary bench (mechanical, electrical, software performance, and biocompatibility testing) and clinical testing was conducted on the modified ARTAS™ System to support a determination of substantial equivalence to the predicate device.
#### SUMMARY
The modified ARTASTM System is substantially equivalent to the predicate device, ARTASTM System (K103428) cleared on April 4, 2011.

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.
