As originally submitted, these devices are intended to be used for applications in fetal, abdominal, intraoperative (defined as the abdominal region and periphery), pediatric, small organ (defined as thyroid, breast and testes), cardiac (UF-4500 only), transrectal, transvaginal (UF-4500 only),, and peripheral vessel scanning. This submission adds conventional and superfical musculoskeletal imaging to both devices. Both the UF-3500 and the UF-4500 are prescription devices intended to by used by or on the order of a physician or similarly qualified health care professional. Both are intended to be used in a doctor's office and all hospital environments; ER ICU, CCU, OR, etc. These devices are intended to be use on any patient; neonate, pediatric, or adult; where the placement and positioning of the transducer does not interfere with or complicate the treatment of the patient. These devices are not intended for home use.
Device Story
General-purpose ultrasound systems (UF-3500, UF-4500) utilize linear probes to perform B-Mode imaging. Devices capture acoustic echo data to generate real-time anatomical images of musculoskeletal structures. Operated by physicians or qualified healthcare professionals in clinical settings (doctor's office, hospital, ER, ICU, OR). Output displayed on-screen for clinician review to identify musculoskeletal soft tissues. No hardware or software modifications were made to support the new musculoskeletal imaging indication; acoustic output remains within established Track 1 limits. Benefits include accurate and reproducible visualization of musculoskeletal anatomy to aid clinical assessment.
Clinical Evidence
Bench testing and clinical evaluation. Skilled sonographers performed imaging using UF-3500 and UF-4500. Images were reviewed by a radiologist to render findings and clinical impressions. Study demonstrated anatomical identification of musculoskeletal soft tissues and confirmed capability for accurate, reproducible imaging.
Technological Characteristics
General-purpose ultrasound systems using microprocessors. Linear probes (FUT-L104, FUT-L106) used for B-Mode musculoskeletal imaging. Acoustic output complies with Track 1 limits (ISPTA3, MI). No changes to hardware, software, or patient-contact materials. Standalone operation.
Indications for Use
Indicated for diagnostic ultrasound imaging of neonate, pediatric, and adult patients. New indications include conventional and superficial musculoskeletal imaging (muscle, tendon, ligament, bursa, and soft tissue in shoulder, elbow, wrist, knee, ankle). Prescription use only.
Regulatory Classification
Identification
An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.
Special Controls
*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

# Description:
The Fukuda Denshi model UF-4500 (K022208) and the model UF-3500 (K955543) are general-purpose ultrasound systems that have been previously found to be substantially equivalent under the Food and Drug Administration's 510(k) process. These devices have not been changed or modified in any way. All software and hardware, all portions of the device that control the acoustic power out are unchanged.
The addition of both conventional and musculoskeletal imaging as intended uses require no changes to the operating instructions.
# Intended Use:
As originally submitted, these devices are intended to be used for applications in fetal, abdominal, intraoperative (defined as the abdominal region and periphery), pediatric, small organ (defined as thyroid, breast and testes), cardiac (UF-4500 only), transrectal, transvaginal (UF-4500 only),, and peripheral vessel scanning. This submission adds conventional and superfical musculoskeletal imaging to both devices.
Both the UF-3500 and the UF-4500 are prescription devices intended to by used by or on the order of a physician or similarly qualified health care professional. Both are intended to be used in a doctor's office and all hospital environments; ER ICU, CCU, OR, etc. These devices are intended to be use on any patient; neonate, pediatric, or adult; where the placement and positioning of the transducer does not interfere with or complicate the treatment of the patient. These devices are not intended for home use.
{2}------------------------------------------------
# Technological Characteristics
The UF-3500 and UF-4500 incorporate microprocessors in a manner similar to the predicate devices. No changes to the hardware or software that control the device or the acoustic output were required to support the claims for musculoskeletal imaging. Conventional and superficial musculoskeletal imaging is possible with linear probes in B-Mode. Patient contact materials have not changed
Both devices' derated acoustic output limits remain below the maximums established for Track 1 devices as listed in the "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers" issued September 30, 1997, and restated below:
| Use | ISPTA3<br>(Mw/CM²) | ISPTA3<br>(Mw/CM²) | MI |
|------------------------|--------------------|--------------------|------|
| Peripheral Vessel | 720 | 190 | 1.9 |
| Cardiac | 430 | 190 | 1.9 |
| Fetal Imaging & Other* | 94 | 190 | 1.9 |
| Ophthalmic | 17 | 28 | 0.23 |
# Testing:
Skilled sonographers using both the UF-3500 and the UF-4500 obtained images. All imaged were reviewed by a radiologist who rendered findings and clinical impression.
# Conclusion:
Based on the anatomical identification of musculoskeletal soft tissues and the diagnostic images obtained from the UF-3500 and the UF-4500, these devises have exhibited the capability of accurately and reproducibly imaging the musculoskeletal structure. Fukuda Denshi has demonstrated through this study that the device is safe and effective in obtaining conventional and superficial musculoskeletal images and is substantially equivalent to the predicate device.

Re: K981404 Fukuda Denshi Ultrasound Scanners Models UF-3500 and UF-4500 Dated: March 23, 1998 Received: April 17, 1998 Regulatory class: II 21 CFR 892.1560/Procode: 90 IYO 21 CFR 892.1570/Procode: 90 ITX
Dear Mr. Geraghty:
We have reviewed your section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug and Cosmetic Act. You may, therefore, market the device, subject to the general controls provisions Act (Act). The general controls provisions of the Act include requirements for registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
This determination of substantial equivalence applies to the following transducers intended for use with the Fukuda Denshi Ultrasound Scanners Models UF-3500 and UF-4500, as described in your premarket notification:
Transducer Model Number
FUT-L104 (5.0 MHz, 60mm) FUT-L106 (7.5 MHz, 40mm)
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic QS inspections, the FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification does not affect any obligation you. ... may have under sections 531 and 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

Page 2 - David J. Geraghty
Please be advised that the determination above is based on the fact that no medical devices have been demonstrated to be safe and effective for in vitro fertilization or percutaneous umbilical blood sampling, nor have any devices been marketed for these uses in interstate commerce prior to May 28, 1976, or reclassified into class I (General Controls) or class II (Special Controls). FDA considers devices specifically intended for in vitro fertilization and percutaneous umbilical blood sampling to be investigational, and subject to the provision of the investigational device exemptions (IDE) regulations, 21 CFR, Part 812. Therefore, your product labeling must be consistent with FDA's position on this use.
This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.
The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:
> Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850
This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.

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).

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.
