Indications for Use
The eNeura Inc. SpringTMS® is indicated for the acute and prophylactic treatment of migraine headache.
Device Story
SpringTMS is a portable, hand-held device for single pulse transcranial magnetic stimulation (sTMS). It delivers a brief, 0.9 Tesla magnetic pulse to the occipital cortex to induce electrical currents, aiming to stop or reduce migraine effects. Designed for patient self-administration in home or office settings. Treatment regimen involves daily prophylactic pulses (4 pulses morning/evening) and acute treatment (3 pulses at onset, repeatable). Device is prescription-only. Healthcare providers use clinical outcomes to monitor treatment efficacy. Benefits include reduction in migraine headache days and decreased reliance on acute medications.
Clinical Evidence
Prospective, multicenter, non-randomized, single-arm observational study (ESPOUSE) with 217 subjects (Safety Data Set). Primary endpoint: mean reduction in migraine headache days over 28 days at 12 weeks. Results showed statistically significant reduction of 2.8 days (FAS, p<0.0001) and 3.0 days (PP, p<0.0001) from baseline. No serious adverse events reported; common AEs included lightheadedness, dizziness, tinnitus, and scalp discomfort.
Technological Characteristics
Portable, hand-held transcranial magnetic stimulator. Delivers 0.9 Tesla single magnetic pulse. Operates via electromagnetic induction to stimulate the occipital cortex. Class II device, Product Code OKP. Contraindicated for patients with metal-containing implants in the head, neck, or upper body (e.g., aneurysm clips, cochlear implants, shunts, stents, metal plates/screws).
Indications for Use
Indicated for acute and prophylactic treatment of migraine headache in patients 18 to 65 years of age with migraine with or without aura.

| Study Design | A prospective, non-randomized, single arm, multi-center observational<br>study designed to evaluate the use of the SpringTMS system in<br>reducing the frequency of headache days against a performance goal. | |
| Number of<br>Patients | A total of 263 subjects were consented between December 2014 and<br>March 2016. 229 of these subjects completed a Baseline Diary and 220<br>were confirmed by the sites to be eligible for participation. There were<br>217 subjects that were assigned Spring TMS devices and these subjects<br>comprise the Safety Data Set. There were 179 subjects who began<br>treatment and completed a Month 1 treatment Diary, but 47 of these<br>subjects did not meet the definition of a Migraine Headache Day<br>(minimum requirement of at least 4 days with moderate to severe<br>headache pain for at least 4 hours at baseline). Thus 132 of these subjects<br>complied with the protocol requirements based upon headache day<br>definition. This was the Full-Analysis Data Set (FAS) described below.<br>There were 117 of these subjects that went on to finish treatment and<br>completed both baseline and Month 3 diaries. This was the Completed<br>Cases data set (CC). Of these subjects 95 complied with the protocol<br>instructions regarding use of the device. This was the per Protocol (PP)<br>data set. | |
| Number of Sites | Seven (7) | |
| Duration of Trial | Each provisionally enrolled subject was followed for 1 month (28±5<br>days) to establish a baseline number of headache days (HD) and<br>confirm final eligibility and then each confirmed enrolled patient was<br>followed for 3 consecutive months (12±1 weeks) of treatment followed<br>by a final assessment. | |
| Treatment | Patients were instructed to treat daily using the following protocol: | |
| Regimen | 1. From the start, treat with 4 Pulses each morning and evening:<br>2 consecutive pulses wait 15 minutes and repeat the 2<br>consecutive pulses. | |
| | 2. Additionally, the patient may treat an acute attack with:<br>3 sequential pulses (early) at the onset of migraine pain<br>Wait 15 minutes, if needed treat with additional 3 pulses<br>Wait 15 minutes, if needed treat with additional 3 pulses<br>Patients may rescue with acute medication 30 minutes after the first<br>three pulses are delivered. | |
| Performance Goal | The originally proposed performance goal for the primary endpoint,<br>representing the mean reduction in headache days for a controlled<br>study, assumed an approximate 80% chronic headache population and<br>was PGMD = -5.3 days. | |
| | This performance goal was amended ahead of un-blinding and the<br>final analysis to PGD=-0.633 in order to reflect the actual population of<br>~20% chronic and ~80% episodic enrollment. | |
| Primary<br>Effectiveness<br>Endpoint | Mean reduction in headache days over a 28-day period at 12±1 weeks<br>(i.e., weeks 9 through 12 from start of treatment period). The null and<br>alternative hypotheses for this endpoint are: | |
| | H0: $μ$ T ≥ PGMD versus Ha: $μ$ T < PGD | |
| | PGD = - 0.633 days. | |
| | where $μ$ T is the mean reduction in migraine headache days from<br>baseline at 12±1 weeks in the treated population and PGD is the<br>Performance Goal. | |
| | Headache day is defined as ≥4 hours of headache pain which at any<br>time reaches moderate or severe intensity. | |
| Secondary<br>Effectiveness<br>Endpoints | 1. The percentage of subjects who had at least a 50% reduction in<br>headache days | |
| | 2. The reduction from baseline in the days of medications use to<br>acutely treat migraine headaches | |
| | 3. The reduction from baseline in the HIT6 impact questionnaire | |
| | 4. The reduction from baseline in the days with headache for more<br>than 4 hours with any pain intensity | |
| | 5. Migraine is defined as >4 hours of headache pain which at any<br>time reached moderate or severe intensity. | |
| Primary Safety<br>Endpoint | The proportion of patients experiencing any adverse event in aggregate<br>and by event. | |
| Inclusion Criteria | 1. Patients 18 to 65 years of age; | |
| | 2. Patients able to understand and communicate in English; | |
| | 3. Migraine with or without aura; | |
| | 4. 4-25 headache days per month (confirmed by 1-month baseline<br>diary, minimum of 5 complete headache-free days/month); | |

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.
