Indications for Use
KLS Martin Individual Patient Solutions (IPS) is intended as a pre-operative software tool for simulating / evaluating surgical treatment options as a software and image segmentation system for the transfer of imaging information from a medical scanner such as a CT based system. The input data file is processed by the IPS software and the result is an output data file that may then be provided as digital models or used as input in an additive manufacturing portion of the system that produces physical outputs including implants, anatomical models, guides, splints, and case reports for use in maxillofacial, midface, & mandibular surgery. KLS Martin Individual Patient Solutions (IPS) implant devices are intended for use in the stabilization, fixation, and reconstruction of the maxillofacial / midface and mandibular skeletal regions in children (2 years of age to < 12 years of age), adolescents (12 years of age - 21 years of age), and adults.
Device Story
System uses CT scan data as input; software performs image segmentation and virtual surgical planning; physician provides interactive feedback to engineers for design iteration; system produces digital models and physical outputs (implants, anatomical models, guides, splints, case reports) via additive or subtractive manufacturing. Used in clinical settings by surgeons for maxillofacial, midface, and mandibular reconstruction. Output devices (implants, guides) assist in surgical precision, stabilization, and fixation of bone segments. Benefits include improved surgical accuracy, reduced intra-operative time, and customized fit for complex volumetric defects. Implants are non-sterile, requiring end-user cleaning and sterilization.
Clinical Evidence
No new clinical trials conducted. Safety and effectiveness for pediatric use supported by analysis of 6 peer-reviewed clinical studies (patients 18 months to 18 years) and risk assessments per FDA pediatric guidance. Studies demonstrate successful use of 3D planning and bone fixation in pediatric panfacial fractures, mandibular reconstruction, and dentofacial deformity correction, showing improved accuracy and reduced operative time.
Indicated for stabilization, fixation, and reconstruction of maxillofacial, midface, and mandibular skeletal regions in children (2-12 years), adolescents (12-21 years), and adults.

### Device Description:
KLS Martin Individual Patient Solutions (IPS) is comprised of a collection of software and associated additive manufacturing equipment intended to produce various outputs to support reconstructive and orthognathic surgeries. The system processes the medical images to produce various patient-specific physical and/or digital output devices which include implants, anatomical models, guides, splints, and case reports.
Patient-specific metallic bone plates are used in conjunction with metallic bone screws for internal fixation of maxillofacial, midface, and mandibular bones. The devices are manufactured based on medical imaging (CT scan) of the patient's anatomy with input from the physician during virtual planning and prior to finalization and production of the device. The physician provides input for model manipulation and interactive feedback by viewing digital models of planned outputs that are modified by trained KLS Martin engineers during the planning session. For each design iteration, verification is performed by virtually fitting

the generated output device over a 3D model of the patient's anatomy to ensure its dimensional properties allow an adequate fit.
Implants are provided non-sterile and are manufactured using traditional (subtractive) or additive manufacturing methods from either CP Titanium (ASTM F67) or Ti-6AI-4V (ASTM F136). These patient-specific devices are fixated with previously cleared KLS Martin screws.
# Indications for Use:
KLS Martin Individual Patient Solutions (IPS) is intended as a pre-operative software tool for simulating / evaluating surgical treatment options as a software and image segmentation system for the transfer of imaging information from a medical scanner such as a CT based system. The input data file is processed by the IPS software and the result is an output data file that may then be provided as digital models or used as input in an additive manufacturing portion of the system that produces physical outputs including implants, anatomical models, guides, splints, and case reports for use in maxillofacial, midface, & mandibular surgery.
KLS Martin Individual Patient Solutions (IPS) implant devices are intended for use in the stabilization, fixation, and reconstruction of the maxillofacial / midface and mandibular skeletal regions in children (2 years of age to < 12 years of age), adolescents (12 years of age - 21 years of age), and adults.
# Technological Characteristics & Substantial Equivalence Discussion:
The intended use of the subject device is identical to the primary predicate device, KLS Martin Individual Patient Solutions (K191028). The subject device differs from the primary predicate mainly in the target patient population and technological specifications. The potential impact on substantial equivalence of each technological difference was addressed through risk analysis and verification and validation testing.
# Similarities to Predicate & Reference Devices
The subject and predicate devices are intended for reconstructive surgery in the facial skeleton and share the same fundamental principles of operation - Software is used to convert individual patient CT scans to digital models for subsequent surgical planning & fabrication of patient-specific devices for use in facial reconstructive surgery.
The subject and predicate devices utilize image data obtained from a CT scan, which is input into validated commercially off-the-shelf (COTS) software applications to transfer patient imaging from DICOM to. STL format and manipulate the images to produce a final design file.
The subject devices are manufactured using identical methods and materials to those cleared in the primary predicate (K191028) and reference device (K182789), with the exception of the new splint material presented in this submission. The new splint material is discussed below in Splints.
Both systems utilize additive manufacturing methods to produce physical output devices that include patient-specific implants, anatomical models, guides, and splints. In addition, the systems produce digital models and case reports for the physician to use for planning of maxillofacial surgeries or to use during surgery.

Materials used in the manufacture of the subject output devices are synthetic polymers, acrylic resins, and titanium (CP titanium & Titanium Alloy), which are identical to what was evaluated in the primary predicate device, K191028.
The specifications for the subject device implants are similar to predicate K191028 with respect to plate style, thickness, width, length, degree of curvature, fixation hole spacing, and number of fixation holes. The titanium screws used to fixate the subject device plates range in diameter from 1.5 mm - 3.2 mm in lengths from - 22 mm, which are identical to the screws previously evaluated in K191028.
The subject and predicate devices are provided non-sterile and require the end-user to process the devices using validated cleaning and sterilization methods prior to use as recommended in the device labeling.
# Differences from Predicate & Reference Devices
# Components & Indications for Use
The primary predicate components include the planning software, implants, and anatomical models. The reference device (K182789) components include the planning software, anatomical models, cutting/marking guides, splints, and case reports. The subject device system combines all previously cleared components and indications for use into one system - planning software, implants, anatomical models, cutting/marking guides, splints, and case reports.
# Target Population
The primary predicate device, K191028, was cleared for the adult population. The purpose of this submission is to expand the patient population to include the following pediatric subpopulations:
- . Children (2 years of age to < 12 years of age)
- Adolescents (12 years of age 21 years of age) ●
A risk assessment has been performed based on FDA guidance, "Premarket Assessment of Pediatric Medical Devices, March 24, 2014" for these subpopulations with supporting peer-reviewed clinical literature to demonstrate the safety and effectiveness of the subject device implants for use in the target pediatric subpopulations.
The reference device, K182789, was previously cleared for all pediatric subpopulations from neonate through adolescent to adult for all IPS components with the exception of permanent implants. The TruMatch CMF Titanium 3D Printed Implant (K170272) has been included as a reference device to support the use of permanent implants in the adolescent population.
# Specifications
The subject device dimensions differ from the predicate by offering additional device sizes to accommodate volumetric defects in facial reconstruction cases for the mandible. Previously cleared specifications for the K191028 predicate plate thickness for the mandibular region ranges from 1.0 mm - 3.0 mm. The subject device plates for the mandibular region differ by ranging in maximum thickness up to 10 mm. This expansion of the design envelope thickness for mandibular implants is supported by our previously cleared primary predicate maxillofacial / midface devices that were cleared for up to 10 mm in maximum thickness to accommodate volumetric defects.

Surgical Innovation is Our Passion
The subject device also proposes two mandibular implant categories with distinct specifications based on type of mandible defect, continuity vs. non-continuity. Minimum thickness for mandible (non-continuity) & maxilla/midface defects is 0.6 mm and 2.0 mm for mandible continuity defects. Minimum thickness for orbital reconstruction is 0.3 mm.
Mandible continuity defects are known to produce larger loads than non-continuity defects or maxillary implants, which is demonstrated by the larger reference device specifications in that situation. Maxillary defects are not subjected to the same loads and thus, subject devices in this area are not designed for dental loading unless supported by bone. Orbital implants are non-load bearing, other than supporting intraorbital contents.
Responsible clinical conditions for volumetric defects include, but are not limited to, bone resection due to tumors or disease, blunt force trauma, facial defects, bone atrophy, and aesthetic augmentation for facial symmetry.
Previously defined specifications for orbital implants in the K191028 predicate were limited to implant thickness, hole spacing, and number of holes. Additional specifications (width, length, and degree of curvature) have been defined for the subject devices in the orbital region to formulate a realistic worst-case construct, provide better control on design variations, and to parallel specifications for the midface and mandible regions. These new specification categories are more restrictive than in the K191028 predicate device and therefore, result in more controllable and mechanically stable design variations.
Any differences in specifications between the subject and predicate devices have been addressed with mechanical bench testing performed on the new worst-case midface, orbit, and mandible plate designs to demonstrate that the design expansion does not raise new or different questions for the determination for substantial equivalence. The K943347 reference device includes traditionally manufactured (subtractive, milled) titanium plates of various sizes and shapes that range in thickness from 0.6 - 1.0 mm and are intended for the stabilization of bone in oral-maxillo-craniofacial surgery. Comparative performance testing and additional bench analysis has addressed any minor differences between the subject, primary predicate, and reference devices.
### Splints
The subject device system includes splints additively manufactured from Ti-6Al-4V (ASTM F136:2013) via SLM methods. The subject device also includes splints additively manufactured from a light-cured resin photopolymer material. The photopolymer resin is composed of acrylate/methacrylate polymers and is manufactured using cDLM methods, which is similar in material composition and uses similar manufacturing methods as the acrylic/methacrylic resins used to fabricate splints from DLP methods previously evaluated under reference device K182789.
A device comparison table of the subject, predicate, and reference devices is provided below:

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.
