Claim of Substantial Equivalence:
This product is similar in design and function to existing patient positioning devices currently in use as accessories to radiation therapy systems.
Two such devices are the Dual Leg Positioner and Knee-and-Foot Lok, manufactured and leqally marketed by Med-Tec, Inc. of Orange City, lowa. These products are listed under regulation number 892.1980, and are exempt from pre-market notification.
The Dual Leg Positioner from Med-Tec is designed to immobilize the lower legs during supine hip and pelvic radiation therapy procedures. The Dual Leg Positioner consists of a one-piece vinyl-covered foam support device with a wedge-like design. The Knee-and-Foot Lok consists of two pieces of vinyl-covered foam supports; the knee portion has a tent-like shape and is designed to capture the hips and lower legs during radiation therapy procedures, while the foot portion is designed to hold the patient's feet. Both positioning pieces of the Knee-and-
{1}------------------------------------------------
Foot Lok can be used alone or in combination with each other. Both also interface with a lock-down bar, allowing the devices to be indexed to the radiation therapy couch.
The foam structure of these devices has a minimal attenuation factor, and blocks little of the radiation therapy beam. Foam support devices such as these have been widely used in radiation therapy patient positioning, and are available in many different shapes and sizes from different companies.
In practice, the Dual Leg Positioner and the Knee-and-Foot Lok devices are secured to the therapy couch tabletop by a lock-down mechanism, or by the patient's own weight. The patient is positioned supine on the treatment couch with his head and torso resting on a cushion or other immobilization device. The patient's thighs and lower legs are then draped over the knee support portion of the device, and the patient's feet are placed into the footrest depressions. This allows the patient's thighs, knees, calves, and feet to be comfortably supported in a manner that allows the patient to be positioned reproducibly for each treatment session. Radiation therapy is then administered in the usual fashion.
The Bionix Thigh Bolster and Foot Positioner is substantially equivalent to the Med-Tec Dual Leg Positioner and Knee-and-Foot Lok in design, form, and function. The Thigh Bolster and Foot Positioner consist of two parts, a thigh support and a footrest. The thigh support portion has a generally tent-like shape, with formed contours to support the thighs and calves. The thigh support portion is designed to interface with the Bionix Secure-Bar, allowing it to be secured to the radiation therapy treatment couch in an index-able fashion. The thigh support portion also has attachment points for interlocks that allow the use of low-melt thermoplastic during the patient immobilization procedure.
The Bionix Thigh Bolster and Foot Positioner is manufactured according to the FDA Good Manufacturing Practice guidelines using standard methods and practices. The Thigh Bolster and Foot Positioner is constructed using different materials than the Med-Tec Dual Leg Positioner and the Knee-and-Foot Lok. The Thigh Bolster and Foot Positioner are constructed of a thermoformed thermoplastic ABS shell with an air core that is an accepted standard in radiation therapy. The thermoformed ABS shell again provides stiffness and strength, while the air core allows for almost no attenuation of the radiation beam during the treatment process. The Thigh Bolster and Foot Positioner also have simple mechanical interlocks that allows the individual parts to be secured to the tabletop of the therapy couch. Other interlocks or clamps allow low-melt thermoplastic to be attached to the Thigh Bolster and Foot Positioner during the patient positioning process.
In clinical practice, the Thigh Bolster and Foot Positioner functions similarly to the Med-Tec Dual Leg Positioner and Knee-and-Foot Lok. The patient is generally positioned on the Thigh Bolster and Foot Positioner in the supine position, with his/her head and torso resting on a foam cushion for comfort. The patient's legs are draped over the Thigh Bolster and Foot Positioner, and the feet are placed into the Foot Positioner. Interlocks with the Bionix Secure-Bar allow both pieces to be indexed and securely attached to the radiation therapy couch. If desired, once the patient is correctly positioned, warm low-melt thermoplastic in its pliable state can be draped over the patient's knees and thighs where it conforms to the patient's anatomy. It is then secured to the Thigh Bolster and Foot Positioner using clamps or other simple mechanical interlocks. When it cools, the low-melt thermoplastic becomes rigid and retains the shape of the patient, allowing him to be positioned and re-positioned securely during the radiation therapy regimen.
{2}------------------------------------------------
Based on the almost identical design and similar features of the Bionix Thigh Bolster and Foot based on the almost luchtical design and Knital Post Lok currently manufactured and r Ustioner to the Dual Leg Posonable to expect that the two devices will have similar solu by McC TCC, Inc., it is reasonably in the minimal attenuation of the properties as regards to stimess, support is a substantially equivalent fashion during the radiotherapy beam, and should therapy process.

boards are employed in clinically identical fashions. Therefore, it is reasonable to conclude boards are employed in climically lacincrer manufactured by Bionix Development Corporation that the Thigh Dolster and aspects to the Dual Leg Positioner and Knee-and-Foot Lok manufactured by Med-Tec, Inc.
The Bionix Thigh Bolster and Foot Positioner is also similar in design and function to the rne blonix Thigh Boloter Feetfix Cushion, both legally marketed by SinMed BV as patient Nicelix Cushlon and the recently in use as accessories to radiation therapy systems. These positioning actived the CE Mark, and conform to Class 1 medical devices under the CE requlations.
The Kneefix Cushion from SinMed BV is designed to position and immobilize the lower legs ric Nnechx easilion Hoelvic radiation therapy procedures. The Kneefix is consists of a duning supine hip the radiation and the vice with a tent-like shape. The wedge-shaped coacca, one preve elossantours are designed to capture the hips and lower legs during rorition therapy procedures, improving the general positioning of the patient undergoing a course of external beam radiation therapy.
The SinMed Feetfix Cushion is a universal patient support cushion for radiation therapy and Xrne Sinilled i cethk Casimilar one-piece, closed-cell construction, and is designed ray and mostle proceed and of the feet with accurate and reproducible immobilization. The Feetfix Cushion is an aid to fast, easy and accurate positioning and immobilization of the legs for the treatment of the treatment of the prostate and pelvic region.
The foam structure of these devices has a minimal attenuation factor, and blocks little of the radiation therapy beam. Foam support devices such as these have been widely used in radiation therapy patient positioning, and are available in many different shapes and sizes from different companies.
ln clinical practice, the Kneefix and Feetfix cushions are secured to the therapy couch by the n canned practicitie the patient is positioned supine on the treatment couch with his/her puticht 3 own river in a cushion or other immobilization device.

stiffness, support strength, and minimal attenuation of the radiotherapy beam, and should function in a substantially equivalent fashion during the patient positioning and the radiation therapy process. Both the Thigh Bolster and Foot Positioner and the SinMed Kneefix Cushion and Feetfix Cushion are intended for use in positioning and re-positioning patients during radiation therapy procedures, and both boards are employed in clinically identical fashions. Therefore, it is reasonable to conclude that the Thigh Bolster and Foot Positioner manufactured by Bionix Development Corporation is substantially equivalent in all aspects to the Kneefix Cushion and Feetfix Cushion manufactured by SinMed BV.

| Common Name: | Head and Neck Immobilization System |
| Classification Name: | Medical charged-particle radiation therapy system, accessory (per<br>CFR section 892.5050). |
| Intended Use: | The SuProne Plus from Bionix Development Corporation is designed<br>to be used for the positioning and re-positioning of patients for<br>receiving radiation therapy. |
Claim of Substantial Equivalence:
This product is similar in design and function to existing patient positioning devices currently in use as accessories to radiation therapy systems.
One such device is the Uni-frame Head and Neck immobilization System, manufactured and sold by Med-Tec, Inc. of Orange City, lowa. The Uni-frame Head and Neck Immobilization System is listed under regulation number 892.5050, and has been assigned the document control number K933227.
The Uni-frame Head and Neck Immobilization System from Med-Tec are designed to position and immobilize the head during radiation therapy procedures. The Uni-frame Head and Neck Immobilization System consist of a headboard that affixes to one of several types of baseplates. These base-plates may be flat or moveable to allow the patient's head and neck to be positively angled to different degrees of flexion, with the patient in the supine position.
{4}------------------------------------------------
Alternative base-plates allow the patient to be placed in the prone position, with his/her head resting on gel chin and forehead pads. The headboard features clamps or similar locking resting on gerenall and roconcomitant use of low-melt thermoplastic for additional patient constraint.
The base-plates may be constructed of acrylic plastic, or may be composed of a carbon fiber/epoxy resin composite material. Likewise, the headboard used in conjunction with the hben poxy resirred may be constructed of acrylic plastic, or may be composed of a carbon fiber/epoxy besin composite material. Such materials are commonly used in the construction of immobilization devices for use in radiation therapy applications.
In clinical practice, the Uni-frame Head and Neck Immobilization System base-plates are secured to the therapy couch tabletop by a lock-down mechanism, or by the patient's own weight. A headboard is affixed to the selected base-plate. The patient is positioned in either the supine or prone position, depending on the therapy regimen selected by the radiation oncologist. The patient is positioned supine with his/her head resting on either a foam or thin oneciously mater for comfort, or on the gel chin and forehead pads for the prone position. Plaste positioned, a mask of low-melt thermoplastic may be used to further immobilize the patient. The low-melt thermoplastic mask is affixed to the headboard using the clamps or locking devices described earlier. Once properly positioned, the patient receives radiation therapy in the usual fashion.
The Bionix SuProne Plus is substantially equivalent to the Med-Tec Uni-frame Head and Neck Immobilization System in design, form, and function. The Bionix SuProne Plus is manufactured according to the FDA Good Manufacturing Practice guidelines using standard methods and practices. The SuProne Plus consists of a flat "headboard" comprised of a methous and prial with a carbon fiber/epoxy skin and a foam core that rests on a base-plate comprised of similar carbon fiber/epoxy composite material without the foam core. Such materials are commonly used in the manufacture of radiation therapy positioning devices because carbon fiber/epoxy composites have superior strength and rigidity, and show minimal attenuation of the radiation therapy beam.
The headboard is designed to hold a patient's head in either the supine or prone position during treatment. An open area in the center of the headboard allows for prone positioning of the patient; during treatment, the patient's forehead and cheekbones rests on a foam cushion for support and comfort. For supine positioning, the patient's head rests on a thin plastic headrest for comfort. With both prone and supine positioning, low-melt thermoplastic may be used to further constrain patient movement. The headboard has clamps or other locking mechanisms that allow the low-melt thermoplastic to attach firmly to the device.
The headboard rests on a base-plate made from a carbon fiber/epoxy resin composite material. This base-plate has three main elements: a base, side supports, and an upper frame that mates with the headboard. The base-plate base has simple mechanical interlocking systems that allow the device to be securely attached to the treatment couch tabletop using an attachment bar or similar device. This allows the SuProne Plus to be repeatedly located in the same position on the treatment couch tabletop for each therapy session.
The side supports of the base-plate provide rigidity and have semi-circular slots milled into the side support of the bas a rigid, open box-like design, and has locating pins that mate with the underside of the headboard. The sides of the upper frame have threaded pins that mate
{5}------------------------------------------------
with the semi-circular slots in the side supports. These threaded pins allow the upper frame to move in an arcing fashion, following the semi-circular slots in the side supports. Tightening the threaded pins locks the upper frame at desired angle.
In clinical practice, the Bionix SuProne Plus functions similarly to the Med-Tec Uni-frame Head and Neck Immobilization System. The SuProne Plus is secured to the therapy couch tabletop either by a lock-down mechanism, or by the patient's own weight. The headboard is mated to the upper frame using the locating pins, and the upper frame is angled to the desired position, and then locked in that position by tightening the threaded pins. The SuProne Plus may be angled to provide either positive or negative neck flexion, as desired. The patient is placed in either the supine or prone position on the board with his head resting on a headrest or foam cushion over the open area. For enhanced patient constraint, a low-melt thermoplastic mask of the patient's head may be used. The mask is made by stretching warm low-melt thermoplastic over his/her head and allowing it to cool to rigidity, taking and holding the shape of the patient's head. The mask is then secured to the headboard using the clamps described earlier. In this fashion the patient is positioned reproducibly on the board. Radiation therapy is then administered in the usual fashion.
Based on the similarities in design, construction, features and function of the Bionix SuProne Plus to the Uni-frame Head and Neck Immobilization System currently manufactured and sold by Med-Tec Inc., it is reasonable to expect the two devices will have similar properties as regards to stiffness, support strength, and minimal attenuation of the radiotherapy beam, and should function in a substantially equivalent fashion during the patient positioning and the radiation therapy process. Both the SuProne Plus and the Med-Tec Uni-frame Head and Neck lmmobilization System are intended for use in positioning and re-positioning patients during radiation therapy procedures, and both devices are employed in clinically identical fashions. Therefore, it is reasonable to conclude that the SuProne Plus manufactured by Bionix Development Corporation is substantially equivalent in all aspects to the Uni-frame Head and Neck Immobilization System manufactured by Med-Tec Inc.
The Bionix SuProne Plus is also similar in design and function to the Accufix Tilting Radiotranslucent Head holder legally marketed by WFR/Aquaplast Corp., of Wyckoff, NJ. The Accufix Tilting Radiotranslucent Head holder is listed under regulation number 892.5050, and has been assigned the document control number K021124.
The Accufix Tilting Radiotranslucent Head holder from WFR/Aquaplast is designed to position and immobilize the head during radiation therapy procedures. The Accufix Tilting Radiotranslucent Head holder consists of an angle-ating headboard affixed to a base-plate. The headboard is moveable to allow the patient's head and neck to be positively angled to different degrees of flexion, with the patient in the supine position. Alternatively, the patient may be placed in the prone position with his/her head supported in the open, central region of the headboard. The headboard features quick release swivel lock clamps to allow the concomitant use of low-melt thermoplastic for additional patient constraint.
The Accufix Tilting Radiotranslucent Head holder is composed of a carbon fiber/epoxy resin composite material. Such materials are commonly used in the construction of immobilization devices for use in radiation therapy applications. The carbon fiber/epoxy resin composite materials have been shown to have exceptional strength and rigidity, and have a minimal attenuation factor that blocks little of the radiation therapy beam.
{6}------------------------------------------------
In clinical practice, the Accufix Tilting Radiotranslucent Head holder base-plate is secured to the therapy couch tabletop by a lock-down mechanism, or by the patient's own weight. The patient is positioned in either the supine or prone position, depending on the therapy regimen selected by the radiation oncologist. In the supine position, the patient is positioned with his/her head resting on either a foam or thin plastic headrest for comfort. For prone positioning, optional attachments support the patient's head in the open, central region of the headboard. Once positioned, a mask of low-melt thermoplastic is be used to further immobilize the patient. Low-melt thermoplastic has the property of becoming soft and pliable when warm so that it can be stretched over and molded to the contoured shape of an object, in this case the patient. As it cools, it becomes rigid, and retains the object's shape. The low-melt thermoplastic mask is affixed to the headboard using the swivel clamps described earlier. Once properly positioned, the patient receives radiation therapy in the usual fashion.
Based on the similarities in design, construction, features and function of the Bionix SuProne Plus to the Accufix Tilting Radiotranslucent Head holder currently manufactured and sold by WFR/Aquaplast Corp., it is reasonable to expect the two devices will have similar properties as regards to stiffness, support strength, and minimal attenuation of the radiotherapy beam, and should function in a substantially equivalent fashion during the patient positioning and the radiation therapy process. Both the SuProne Plus and the WFR/Aquaplast Accufix Tilting Radiotranslucent Head holder are intended for use in positioning and re-positioning patients during radiation therapy procedures, and both devices are employed in clinically identical fashions. Therefore, it is reasonable to conclude that the SuProne Plus manufactured by Bionix Development Corporation is substantially equivalent in all aspects to the Accufix Tilting Radiotranslucent Head holder manufactured by WFR/Aquaplast Corp.

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.

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.
