The BrainsWay Deep TMS System is indicated for the treatment of depressive episodes in adult patients suffering from Major Depressive Disorder who failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode.
Device Story
Brainsway Deep TMS System is an electromechanical device for non-invasive neuromodulation. It uses an electromagnetic coil (H1-Coil) placed against the patient's scalp to deliver brief, rapidly alternating magnetic pulses. These pulses induce electric fields in the prefrontal cortex, causing localized axonal depolarization and neuronal activation. The system includes a mobile cart, neurostimulator, cooling system, positioning arm, and helmet. It is operated by clinicians in hospitals or clinics. The device now supports an intermittent theta-burst (iTBS) stimulation protocol, which delivers 600 pulses in approximately 3 minutes. By providing a shorter treatment duration compared to traditional high-frequency protocols, it improves clinical workflow efficiency while maintaining therapeutic efficacy for MDD patients.
Clinical Evidence
Non-inferiority study comparing iTBS protocol (n=66) to High Frequency (HF) protocol (n=80) using the BrainsWay Deep TMS device. Primary endpoint: change in HDRS-21 score from baseline to 5 weeks. Results showed the upper limit of the confidence interval for the difference between groups was less than the 3-point non-inferiority margin, confirming non-inferiority of iTBS to HF stimulation.
Technological Characteristics
Electromechanical TMS system; air-cooled electromagnetic H1-coil; biphasic waveform; 120% motor threshold intensity. Complies with IEC 60601-1, IEC 60601-1-2, IEC 62304, ISO 10993-5/10, and ISO 14971. Connectivity: Standalone system. Software: IEC 62304 compliant.
Indications for Use
Indicated for adult patients (≥18 years) with Major Depressive Disorder (MDD) who have failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode.

### Device Description:
The BrainsWay Deep TMS System enables direct non-invasive activation of deep brain structures. Transcranial magnetic stimulation (TMS) is a non-invasive technique used to apply brief magnetic pulses to the brain. The pulses are administered by passing high currents through an electromagnetic coil placed adjacent to a patient's scalp. The pulses induce an electric field in the underlying brain tissue. When the induced field is above a certain threshold, and is directed in an appropriate orientation relative the brain's neuronal pathways, localized axonal depolarizations are produced, thus activating neurons in the targeted brain structure.
The BrainsWay Deep TMS System is composed of the following main components:
- 1. Cart
- a) TMS Neurostimulator
- b) Cooling System
- c) Positioning Device
- 2. Helmet
- a) Aiming Apparatus (i.e., ruler/grid)
- b) Electromagnetic Coil (H1-Coil)
- c) Cap
# Intended Use/Indication for Use:
The BrainsWay Deep TMS System is indicated for the treatment of depressive episodes in adult patients suffering from Major Depressive Disorder who failed to achieve satisfactory improvement from previous anti-depressant medication treatment in the current episode.
# Performance Standards:
BrainsWay Deep TMS System complies with the following FDA recognized consensus standards:

### Non-Clinical (Bench) Performance Data:
The clinical performance of iTBS is dependent on the stimuli being delivered at an equal intensity, to ensure that a constant dose of stimuli is delivered during treatment. The Theta Burst Stimulation verification testing demonstrated that the intensity of the individual stimuli in iTBS stimulation protocol is equal and maintained constant throughout the delivery of the entire treatment.
Tests were conducted on the cleared BrainsWay Deep TMS Systems for the iTBS stimulation protocol according to the FDA Guidance Document Class II Special Controls Guidance Document: Repetitive Transcranial Magnetic Stimulation (rTMS) Systems. These tests included Output Waveform, Electrical Field Spatial Distribution and Magnetic Field Strength Gradient Testing. Additional performance testing included electrical and mechanical safety testing, electromagnetic compatibility testing and software validation testing in compliance with FDA guidelines for software validation and IEC 62304 standard requirements. The results of the performance tests demonstrated that the Brains Way Deep TMS System is substantially equivalent to the predicate device.
# Animal Performance Data / Histology Data:
Not Applicable
# Clinical Performance Data:
The safety and effectiveness of the BrainsWay Deep Transcranial Magnetic Stimulation (TMS) device for the intended use of Major Depressive Disorder (MDD) using the intermittent theta-burst (iTBS) stimulation protocol was demonstrated in a non-inferiority analysis, comparing the iTBS treatment with the FDA cleared BrainsWay Deep TMS device to the High Frequency (HF) protocol using the same device. Following is a summary of the study.
| Study Objective | The objective of the current study was to evaluate the non-<br>inferiority of the iTBS stimulation protocol with the BrainsWay<br>Deep TMS (H1-Coil) System compared to the FDA-cleared<br>High Frequency (HF) stimulation protocol using the same<br>BrainsWay Deep TMS (H1-Coil) System, for the treatment of<br>MDD. |
|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Study duration | 5 weeks |
| Number of subjects | 66 subjects received iTBS stimulation protocol and 80 subjects<br>received HF stimulation protocol. |
| Primary Endpoint | The primary efficacy endpoint was the change from baseline to<br>5 weeks visit (after 20 treatment sessions) in the patients<br>depression level as measured by the HDRS-21 score |
| Secondary Endpoints | HDRS-21 Response Rate at 5 weeks, where response is defined as a ≥50% reduction in HDRS-21 score from baseline HDRS-21 Remission Rate at 5 weeks, where remission is defined as HDRS-21 score < 10 Change in CGI-S from baseline to 6 weeks CGI-S Response Rate at 6 weeks, where response is defined as 2 point reduction in CGI-S score from baseline CGI-S Remission Rate at 6 weeks, where remission is defined as CGI-S score ≤ 2 |
| Intervention | iTBS stimulation protocol compared to High Frequency (HF) stimulation protocol (both stimulation protocols were delivered using the FDA cleared BrainsWay Deep TMS device). |
| Eligibility criteria | Outpatients Men and women ≥ 18 years of age (or 22-68 years of age in the multicenter MDD study) Diagnosis of Major Depression Disorder |
| Study Hypothesis | Null Hypothesis: The mean change in HDRS-21 score from baseline at 5 weeks in the iTBS Deep TMS group is inferior to the mean change in HDRS-21 score from baseline at 5 weeks in the HF Deep TMS group, by more than 3 points.<br>Alternative Hypothesis: The mean change in HDRS-21 score from baseline at 5 weeks in the iTBS Deep TMS group is inferior to the mean change in HDRS-21 score from baseline at 5 weeks in the HF Deep TMS group, by less than 3 points, i.e. is non-inferior. |
| Summary of Results | The non-inferiority analysis of the change from baseline between the two treatment groups was assessed. Since the upper limit of the confidence interval was less than the non-inferiority margin of 3 points, the null hypothesis of inferiority was rejected, indicating non-inferiority between the iTBS Deep TMS and HF Deep TMS treatments, when adjusted for baseline HDRS-21 scores. In summary, the change from baseline was similar between the two treatment groups at 5 weeks, which demonstrated the non-inferiority of the iTBS Deep TMS treatment |
{7}------------------------------------------------
Based on clinical results, the BrainsWay Deep TMS device with iTBS is as safe and effective as the predicate devices and enables a reduced treatment time for the benefit of both patient and operator.

The modified device has the same intended use as the BrainsWay Deep TMS Systems cleared in 510(k) K122288 and K173540. The subject device includes a Theta Burst stimulation protocol for the same intended use. The inclusion of the iTBS stimulation protocol is substantially equivalent to the Mag Vita TMS Therapy System w/ Theta Burst Stimulation (Tonica Elektronik A/S, cleared in 510(k) K173620).
Both the modified device and the cleared BrainsWay Deep TMS Systems are similar in terms of their intended prescription use only, suitable for adult population, indicated for anatomical sites according to indications for use and to be used in hospital or clinic settings.
All components of the subject BrainsWay Deep TMS System are identical to the previously cleared, predicate devices and have the same mechanism of operation and use the same underlying technology. The performance characteristics, including the Output Waveform, Electrical Field Spatial Distribution and Magnetic Field Strength Gradient are the same as the previously cleared BrainsWay Deep TMS Systems (K122288 and K173540). The additional non-clinical and clinical performance tests demonstrated substantial equivalence of the subject BrainsWay Deep TMS device to the predicate devices for the iTBS stimulation protocol.
#### Conclusions:
Consequently, it can be concluded that the modified BrainsWay Deep TMS System is substantially equivalent to the predicate BrainsWay Deep TMS System, cleared under 510(k) K122288 and the BrainsWay Deep TMS System, cleared under 510(k) K173540. The inclusion of the iTBS stimulation protocol is substantially equivalent to the MagVita TMS Therapy System w/ Theta Burst Stimulation (Tonica Elektronik A/S, cleared in 510(k) K173620). Therefore, the modified BrainsWay Deep TMS Systems can be legally marketed in the USA.

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).

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.
