The Focal One device is indicated for transrectal high intensity focused ultrasound (HIFU) ablation of prostate tissue.
Device Story
Focal One is a high-intensity focused ultrasound (HIFU) system for prostate tissue ablation. It utilizes an endorectal dynamic focusing probe to deliver high-energy ultrasound waves that generate heat to destroy targeted prostate tissue. The system includes a motorized probe positioning unit, RF amplifier, computer control, and a cooling system (Ablasonic liquid) to protect the rectal wall. Operated by a physician in a clinical setting, the device uses dual touch-screens, mouse, and keyboard for control. It integrates ultrasound imaging with other DICOM-compliant modalities to localize and target tissue. The process involves stepwise ablation of targeted areas. Clinical benefits include prostate volume reduction and PSA stabilization. The device is an evolution of the Ablatherm series, featuring enhanced imaging fusion capabilities.
Clinical Evidence

The Focal One® device is indicated for transrectal high intensity focused ultrasound (HIFU) ablation of prostate tissue.
#### Device Description:
The Focal One® is an evolution from the previous generation device, designed by EDAP: Ablatherm Integrated Imaging (K153023) and Ablatherm Fusion (K172285). The Focal One® consists of the Focal One® module with a software control system, an endorectal dynamic focusing probe, a leg holder, a set of single use disposables and a coupling liquid pouch.
The Focal One® module consists of a motorized and manual endorectal dynamic focusing probe positioning unit, a RF amplifier to power the transducer, a computer to control device operation, a cooling system to cool Ablasonic (coupling liquid) and built-in safety features. It also allows the user to control the treatment while providing different user interfaces: two dual touch-screens, mouse, keyboard and printer. The Focal One® energy is delivered via an endorectal dynamic focusing probe, which includes an imaging system. The high-energy ultrasound waves propagate through the rectal wall and are focused on a portion of the prostate, generating intense heat and causing the ablation of tissue within the focal area. The process is then repeated in a stepwise fashion to destroy the targeted tissues within the prostate. The endorectal dynamic focusing probe is attached to a support, enabling movements in the longitudinal, transverse, vertical and angular directions, and in rotation. A coupling liquid pouch (Ablasonic®) included in the FocalPak disposable kit, attached to a stand, maintained at a controlled temperature flows continuously (via a peristaltic pump) into the balloon to preserve the rectal wall from heating associated with the treatment. The module is mounted on four multidirectional wheels allowing an easy positioning of the device in the treatment room.

#### Clinical Data
A clinical report summarizing data on subjects treated with the Focal One® High Intensity Focused Ultrasound (HIFU) device to provide evidence of the safety and effectiveness of the ablation of prostate tissue has been provided in support of this submission. The EDAP data collection is a retrospective analysis of prospective clinical studies that demonstrates the efficacy of Focal One® HIFU supported by targeted volume and PSA reduction data and through prostate biopsies data.
This clinical report includes data from 100 subjects treated with Focal One® HIFU in four prospective clinical trials conducted in Europe. Despite the data having been collected in four separate studies, the patients in each trial had similar baseline and demographic characteristics, and all trials shared the same treatment approach (i.e., focal treatment of prostate tissue).. The studies were conducted primarily in sequential order over a period of 37 months which allowed for cumulative user group experience over time.
All subjects were treated with the commercial version of the device, demonstrating that the device performs as intended under anticipated conditions of use. Within the set of clinical trials presented, all selected
{5}------------------------------------------------
subjects were evaluated prior to the study procedure and then followed at 3 months, 12 months, 18 months and 24 months post-HIFU.
Evidence of prostate tissue ablation was provided through post-HIFU evaluation of targeted volume, PSA reduction and stability as well as biopsy results. All adverse events were collected regardless of their relationship to the HIFU procedure. The majority of adverse events resolved with the exception of some cases of erectile dysfunction and urinary dysfunction.
#### Prostate volume reduction
Within the entire population of subjects considered in this analysis, after the focal HIFU treatment, the prostate volume, assessed by MRI changed significantly. For paired cases (subjects for which MRI data are available at baseline and measurement point) (78 subjects), it went from 49.8 ± 23.1 mL (median 44.0 mL) to 38.6 ± 25.5 mL (median 31.5 mL) (p<0.001). This represents a 22.7% reduction (95% confidence interval 17.6%; 27.8%).
#### PSA reduction Following Focal HIFU Procedure
PSA reduction is also presented as supporting evidence of ablation. Ninety-nine subjects presented some reduction of PSA during the follow-up phase.
PSA reductions from baseline to 6 and 12 months are presented in the table below. As shown in this table, the mean PSA reductions are statistically significant at both 6 months (p<0.001) and 12 months (p<0.001).
| Variable | N | Mean | 95% CI | Significance of<br>reduction |
|-------------------------------------------------|----|--------|----------------|------------------------------|
| PSA reduction at 6<br>months (ng/mL) | 93 | -3.7 | - 4.3; - 3.1 | < 0.001 |
| Percentage PSA<br>reduction at 6<br>months (%) | 93 | - 53.0 | - 60.2; - 45.8 | |
| PSA reduction at<br>12 months<br>(ng/mL) | 82 | -3.7 | - 4.2; - 3.1 | < 0.001 |
| Percentage PSA<br>reduction at 12<br>months (%) | 82 | - 54.4 | - 60.2; - 48.6 | |
The PSA nadir (lowest value measured during window of PSA assessment) is reached around 8 months after HIFU (mean nadir time achievement: 8.4 ± 6.3 months) with a median at 6.2. The mean PSA nadir is 2.2 ± 1.6 ng/ mL, with a median of 2.0 ng/mL.
In addition, in the analyzed population, the PSA velocity from first PSA assessment after HIFU procedure, to last not censured PSA measure performed, is - 0.57 ± 5.30 ng/mL/year (median 0.018 ng/mL/year) (see table below).
| Variable | N | Mean | 95% CI |
|----------------------------|----|-------------------|--------------|
| PSA velocity<br>ng/ml/year | 96 | - 0.57 ng/mL/year | - 1.65, 0.50 |
PSA reduction and subsequent stability provides additional evidence of prostate tissue ablation.
{6}------------------------------------------------
### Histological evidence of tissue ablation
In the set of selected clinical trials presented, during the study, treatment outcome was monitored: a multiparametric MRI was performed, followed by a series of prostatic biopsies allowing the distinction between HIFU targeted area and not targeted area outcomes. Ninety-seven of the 100 subjects underwent biopsy. In the present data collection analysis, subjects who did not undergo control biopsies, in the duration of their follow-up in their respective study, were considered as positive.
This corresponds to a negative biopsy rate at the level of the targeted area of 63% (95% confidence interval 53.5%; 72.5%) (see table below).
| Number of subjects | Negative Biopsy(1) | % | Positive Biopsy(2) | % |
|--------------------|--------------------|------|--------------------|------|
| 100 | 63 | 63.0 | 37 | 37.0 |
(1) Negative biopsy in targeted area. (2) Positive biopsy in targeted area or missing biopsy (3 in total) (noncompliance).
Based on the analysis of the post-HIFU prostate volume evolution, the PSA reduction and the control biopsies, results provide evidence of the effectiveness of the Focal One® device in ablating specifically prostate tissue.
The information below provides a detailed view of the adverse events reported during the European prospective clinical studies evaluating the focal treatment of the Focal One which were submitted as evidence of the safety and effectiveness of the ablation of prostate tissue. Given the retrospective nature of the 510(k) clinical data, a third party CRO audited the adverse event tabulations to verify the reliability and completeness of the data collection.

*Note the Ablatherm Integrated Imaging 510(k) (K153023) listed 5 FPS as the typical Transverse Imaging frame rate. This was a typographical error. The typical Transverse Imaging frame rate should have been listed as 25 FPS.
The claim of substantial equivalence of the Focal One to the Ablatherm (K153023) and Sonablate (K160942) is also based on the comparison of clinical outcomes such as targeted volume as related to adverse events, PSA reductions from baseline, and biopsy results.
The claim of substantial equivalence for the image fusion function of Focal One "Fusion of ultrasound with other imaging modalities (DICOM)" references K172285 for the Ablatherm Fusion variant which was cleared for this feature.
#### Conclusion
Based on the indications and intended use, device design, performance and conformity with recognized consensus standards, as well as clinical data, the Focal One is substantially equivalent to the Ablatherm® Integrated Imaging (K153023) and the Sonablate® (K160942). The Focal One is as safe and effective as the predicate devices. Minor performance and technological differences between the Focal One and its predicate devices do not present new issues of safety and effectiveness when compared to the predicate devices. In vivo and in vitro testing, clinical testing and validation of the Focal One software confirm that the Focal One performs as intended. Thus, the Focal One is substantially equivalent.

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.
