The CSO is intended for use on infants from three to eighteen months of age with moderate to severe non-synostotic positional plagiocephaly, including infants with plagiocephalic, brachycephalic, and scaphocephalic shaped heads. The CSO is intended to apply gentle pressure to prominent regions of the infants's cranium, and to provide realignment space for depressed cranial regions to improve cranial symmetry and or shape.
Device Story
Custom-made cranial orthosis for infants with non-synostotic positional plagiocephaly. Device fabrication involves taking a plaster cast of the infant's calvarium, creating a modified cranial model corrected for symmetry, and vacuum-forming the orthosis over this model. Device consists of a semi-rigid outer shell (polypropylene/polyethylene copolymer) and a soft inner foam liner. Used in a clinical setting under physician prescription; applied by caregivers. Operates as a dynamic orthotic by applying gentle, low-energy pressure to prominent cranial regions while providing space for growth in depressed regions. Caregivers monitor fit and skin integrity every 3-4 hours; practitioners perform biweekly follow-up measurements to track head circumference and growth. Improves cranial symmetry and shape over a standard 3-4 month treatment period.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on design, material composition, and intended use similarities to the predicate device.
Technological Characteristics
Dynamic cranial orthosis. Materials: Orthopedic grade copolymer polypropylene (90%) and polyethylene (10%) outer shell; medium durometer polyethylene foam (Volara) inner liner. Construction: Vacuum-formed over a modified plaster cast model. Design: Semi-rigid shell with lateral opening and top ventilation. Biocompatibility: Inner lining tested for long-term skin contact.
Indications for Use
Indicated for infants 3-18 months old with moderate to severe non-synostotic positional plagiocephaly (plagiocephalic, brachycephalic, or scaphocephalic head shapes). Contraindicated for infants with craniosynostosis or hydrocephalus.

Both devices are Not intended for infant's with craniosynostosis or hydrocephalus. Both devices provide cranial orthotic treatment for infant's with nonsyndromic head deformity as a result of the utero process: e.g. compressional forces exerted by the lumbosacral spine, uterine malformation, fetal malpositioning, multiple fetuses oligohydramnios, and the current supine positioning recommendations. By design the CSO and DOC have a single lateral opening on the side adjacent to the flattened occipital-parieto region, provide a generous opening on top for air flow, and are very light in weight. Both devices can easily be adjusted for normal growth during the treatment process, and are easy to apply and remove by the care giver.
Both devices are of thermoplastic construction consisting of a semirigid outer shell bonded to a soft inner lining. Both outer shells are of Orthopedic grade plastic with hazard data all within OSHA permissible exposure limits with none know medical conditions aggravated by exposure. The CSO and DOC inner linings have been tested and approved by the FDA for long term skin contact. Both devices are of dynamic design , and when applied to an infant mild pressure, a low energy load , will constrain and correct abnormal growth . Normal growth will take place in the provided space and the cranial symmetry will be much improved.Standard treatment time for both cranial orthoses is three to four months.

By design specifications and design intent the CSO is vacuum formed over a modified cranial model obtained from a plaster cast taken of the infant's calvarium . Both the cranial solutions orthosis and the predicate device are formed only after the cranial model has been corrected or restored to as near as complete symmetry as possible. This exact correction will produce a very accurate and effective fit.
In keeping with our goal: To provide the safest, effective, and most comfortable cranial orthosis on an individual, custom, and prescription basis we at Cranial Solutions employ an important clinical tool. Our CSO Anthropometric measurement form. After obtaining the plaster impression we complete this form and explain it to parent or care giver. By encouraging the parents to be involved in the measurements(progress) they will keep and understand the need for biweekly follow-up appointments. By having the cranial orthosis and head circumference evaluated and recorded at preset intervals by the practitioner the risk factors can be reduced and the infant will have a much improved clinical outcome with their cranial orthosis.

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.
