Distraction distance and distraction rate
Indications for Use
The OsteoMed smartflex Cranial Spring Distraction System is intended for use in the treatment of cranial conditions such as syndromic craniosynostosis and congenital deficiencies in which osteotomies and gradual bone distraction are indicated. This device is intended to provide temporary stabilization and gradual lengthening of the cranial bones. This device is intended to be removed after consolidation. The OsteoMed smartflex Cranial Spring Distraction System is intended for single patient use only.
Device Story
The OsteoMed smartflex Cranial Spring Distraction System is an internal distraction osteogenesis device used in pediatric cranial surgery. It consists of stainless steel distractors anchored to the cranium via hook feet. Unlike traditional threaded-rod distractors that require manual activation by a surgeon or parent, this device applies continuous spring force to the skull bones to facilitate gradual remodeling and lengthening of prematurely closed sutures. The system includes auxiliary instruments (pliers, benders, cutters) for placement. The device is implanted during surgery and removed after bone consolidation. It provides a passive, continuous distraction mechanism compared to the active, manual distraction of predicate systems. Clinical benefits include gradual bone expansion for cranial conditions; the device is intended for single-patient use.
Clinical Evidence
No clinical trials were conducted for this submission. Substantial equivalence is supported by bench testing, including Finite Element Analysis (FEA) comparing stress on infant cranial bone against the predicate, and verification of spring geometry and force targets using optical comparators. Additionally, the manufacturer provided retrospective clinical data from literature regarding 91 cases of cranial spring distraction (performed by a physician) to verify distraction rates and safety profiles, showing a mean distraction rate of 1.39mm/day.
Technological Characteristics
Internal distractor made of medical grade stainless steel (ASTM F-138). Distraction mechanism utilizes continuous spring force rather than manual threaded rods. Anchored to cranial bone via hook feet. Provided sterile via gamma sterilization. Dimensions allow for a maximum distraction distance of 55mm.
Indications for Use
Indicated for pediatric patients, infants aged 1 month to 2 years, with syndromic craniosynostosis or congenital cranial deficiencies requiring osteotomy and gradual bone distraction for temporary stabilization and lengthening.
Regulatory Classification
Identification
A preformed nonalterable cranioplasty plate is a device that is implanted in a patient to repair a skull defect and is constructed of a material, e.g., stainless steel or vitallium, that cannot be altered or reshaped at the time of surgery without changing the chemical behavior of the material.

{1}------------------------------------------------
#### Device Description:
The OsteoMed smartflex Cranial Spring Distraction System is a distraction osteogenesis system consisting of distractors in various sizes. The distractor is anchored to the cranium by the distractor foot plate. The distractor gradually distracts the bone segments by applying a continuous force to the bones of the skull facilitating remodeling to expand the prematurely closed suture. The distractors are removed after consolidation.
The instruments used with the system are pliers, benders, plate cutters and other instruments to facilitate the placement and removal of the OsteoMed smartflex cranial spring distractors.
The OsteoMed smartflex Cranial Spring Distractors are made from Medical Grade Stainless Steel per ASTM F-138.
#### Indications For Use/Intended Use:
The OsteoMed smartflex Cranial Spring Distraction System is intended for use in the treatment of cranial conditions such as syndromic craniosynostosis and congenital deficiencies in which osteotomies and gradual bone distraction are indicated. This device is intended to provide temporary stabilization and gradual lengthening of the cranial bones. This device is intended to be removed after consolidation. The OsteoMed smartflex Cranial Spring Distraction System is intended for single patient use only.
Intended use is equivalent to the OsteoMed Cranial Distraction System and the KLS-Martin predicate devices.
#### Target Population:
Pediatrics; Sub-population - Infant greater than 1 month to 2 years of age
#### Technological Characteristics:
The OsteoMed and KLS predicate devices are internal distractors for bone elongation, which distracts manually via a threaded rod and are anchored using bone screws. The KLS distractor predicate has hook feet which anchor to the cranial bone edge and uses bone screws to anchor to the cranial bone. The OsteoMed smartflex Cranial Spring Distractor is also an internal distractor for bone elongation as the predicate devices, but it distracts via continuous spring force and is anchored by hook feet to the cranial bone edge.
Material used for the OsteoMed smartflex Cranial Spring Distractor is medical grade stainless steel. The material used for the OsteoMed External Mandibular Distraction System (K063792) implantable K-wires, which are implanted during distraction, are medical grade stainless steel. The stainless steel material used in the OsteoMed smartflex Cranial Spring Distractor and the OsteoMed Implantable K-wire is biocompatible.

#### Performance / Clinical Data:
The OsteoMed smartflex Cranial Spring Distraction System was compared to the distraction rates and verified forces of the OsteoMed Cranial Distraction System. Verification testing consisted of the following tests;
- . Finite Element Analysis of Forces Applied to Adjacent bone simulating infant skull properties for the Cranial Vault Distractor Predicate and the OsteoMed SmartFlex Cranial Spring Distractor were created. The results show that both devices exerted a stress on the cranial bone below the vield strength of infant cranial bone. The stress on the cranial bone for the Cranial Spring Distractor was 80% below the stress on the cranial bone of the Cranial Distractor (predicate).
- Distraction distance was evaluated graphically using clinical data obtained by . surgeons with cranial spring devices similar to our device. The data included 91 clinical cases performed on infants ranging in age from 3 - 8.5 months with cranial springs manufactured by a physician in cranial distraction, 31 cases reached 55mm of distraction and 60 cases went safely beyond 55mm with only one clinical complication, a skin infection and 3 spring related complications (repositioning of the springs). The maximum possible distraction distance of the OsteoMed Cranial Spring Distractor is 55mm because that is the maximum length at free state that does not compromise patient safety.
- Distraction rate was obtained from the clinical data and distraction rates . compared to the predicate. The distraction rate on average with a six week duration was 1.39mm per day.
- The OsteoMed smartflex Cranial Spring Device design was verified to prove the . spring geometry and force targets were met as described in the literature. Spring geometry was verified using an optical comparator and the implants were compressed between the footplates to simulate initial force at implantation, where the force was measured.
The indications for use of the OsteoMed smartflex Cranial Spring Distraction System are the same as the OsteoMed Cranial Distraction System (K121304) and KLS-Martin Molina Distraction System (K003883) predicate devices.
Clinical Testing is not required to support substantial equivalence.
In conclusion, the device is safe and effective and performs as well as the OsteoMed Cranial Distraction System and the KLS-Martin predicate devices.
#### Substantial Equivalence:
Substantial equivalence for this device is based on similarities in intended use, indications for use, function, performance, and operational principle to the predicate devices, OsteoMed Cranial Distraction System (K121304) and KLS-Martin Molina Distraction System (K003883), based on their promotional materials, labeling and clearance letters. The basis for substantial equivalence for this device is also on similarities in materials with the OsteoMed External Mandibular Distraction System (K063792) implantable Stainless Steel K-wires base on their promotional materials, labeling and clearance letters. The system is provided sterile based on the predicate device (K922211) Sterilization Testing.

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.
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.
