#### Overview.
This pre-market notification is being submitted in good faith in an effort to satisfy the requirements of the FDAMA guidelines. Additionally, the FDA does not have any voluntary standards for this device and no standards have been applied.
The Bionix T-Form Extremity Immobilizer is intended to be used for the positioning and re-positioning of patients undergoing or receiving a course of external beam radiation therapy for the treatment of cancer and other diseases. This device has been most likely classified as Class II by the FDA Panel on Radiology, falling under CFR 892.5050.
The Bionix T-Form Extremity Immobilizer has been designed using the design control procedures of the Bionix Quality System in compliance with the Good Manufacturing Practice (GMP) Quality System Regulations of the FDA/CDRH. This pre-market notification will draw information from the Design History File for this device and format it for efficient review.
#### Background and Principles of Operation.
The Bionix T-Form Extremity Immobilizer is intended to be used for the positioning and re-positioning of patients undergoing or receiving a course of external beam radiation therapy for the treatment of cancer and other diseases.
The T-Form Extremity Immobilizer from Bionix Development Corp. consists of a thermoformed patient support device with attachment areas for accessories. The T-Form Extremity Immobilizer is thermoformed from an ABS plastic material so that the resulting contoured shell is lightweight and thin-walled, providing low attenuation for
{2}------------------------------------------------
1
unobstructed passage of the radiation therapy beam. The T-Form Extremity Immobilizer is specifically designed for immobilization of the upper and lower extremities.
The T-Form Extremity Immobilizer has a generally rectangular shape, with pre-formed areas that allows,the device to be securely attached to the treatment couch tabletop. Specifically, there are pre-formed depressions with threaded holes that allow the T-Form Extremity Immobilizer to screw onto an attachment bar that can lock onto the treatment couch tabletop. These pre-formed areas can be found on both the top and side of the device, allowing the T-Form Extremity Immobilizer to be used in either a longitudinal or transverse orientation to allow greater flexibility in patient positioning. This allows the T-Form Extremity Immobilizer to be repeatedly located in the same position on the treatment couch tabletop for each therapy session.
The T-Form Extremity Immobilizer has a central thermoformed depression to allow the use of optional vacuum cushions as part of the patient immobilization process. Vacuum cushions contain expanded polystyrene beads in an airtight vinyl bag, with a valve for attachment to a vacuum pump. In practice, the patient's extremity is positioned on the bag which is then evacuated using the vacuum pump. As the bag is evacuated, the polystyrene beads form a rigid cushion that accurately conforms to the contours of the patient's extremity, and also to the sides of the thermoformed depression. The latter allows the vacuum cushion to locate reproducibly onto the board, while the patient's extremity can be reproducibly located into the pocket formed into the vacuum cushion.
Attachment points for standard low-melt thermoplastic (used to restrain patients undergoing radiation therapy) are provided for use in immobilizing the patient's extremities. A simple mechanical interlocking system allows the attachment of the lowmelt thermoplastic to the T-Form Extremity Immobilizer. 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. For the T-Form Extremity Immobilizer two non-adherent plastic handles are used to hold the low-melt thermoplastic. Simple screwtightened clamps mounted on the surface of the T-Form Extremity Immobilizer are used to secure the non-adherent plastic handles to the board. The low-melt thermoplastic sheet is stretched over the patient's extremity in its pliable form; once molded to the patient's anatomy, the customized low-melt thermoplastic sheet can be placed over the patient and "locked down" to the T-Form Extremity Immobilizer to ensure proper positioning for every therapy session.
The Bionix T-Form Extremity Immobilizer has a thermoformed ABS shell that displays minimal attenuation of the radiotherapy beam. This is due primarily to the fact that the thermoformed shell is relatively thin. The device has an open, air filled core that is radiolucent. The resulting structure provides strength and rigidity, and is ideal for producing a device that reproducibly positions patients and yet does not interfere with the administration of therapeutic radiation. Patient positioning devices with this type of structure are common in radiation therapy. They come in many varieties and are manufactured by several companies; examples including Civco Medical Solutions.
{3}------------------------------------------------
In clinical practice, the Bionix T-Form Extremity Immobilizer is secured to the therapy couch tabletop by attachment to a lock-down bar. The patient's extremity is positioned on the T-Form Extremity Immobilizer as desired, either directly onto the board or with the use of a vacuum cushion that has been evacuated to conform to the patient's anatomy. Low-melt thermoplastic is heated, and then draped in its warm, pliable state over the patient's extremity, and then secured to the T-Form Extremity Immobilizer using the screw-down clamps. When it cools, the low-melt thermoplastic becomes rigid and retains the shape of the patient's extremity, allowing it to be positioned and re-positioned securely during the radiation therapy regimen. Radiation therapy is then administered in the usual fashion.
#### Comparison to Predicate Device:
j
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 Multifix, manufactured and legally marketed by Civco Medical Solutions of Orange City, Iowa. The Multifix immobilization system is used to position and immobilize the upper and lower extremities during a course of radiation therapy. Another such device is the HipFix, also manufactured and legally marketed by Civco Medical Solutions of Orange City, Iowa. The HipFix hip and pelvis immobilization system is used to position and immobilize the hips and lower extremities during a course of radiation therapy.
The Multifix has a base-plate that may be made of acrylic sheet, or preferably, from carbon fiber/foam composite material for enhanced radiolucency. Such structures are commonplace in radiation therapy positioning products to provide rigidity and support while at the same time minimizing attenuation of the radiation therapy beam. The baseplate has four sets of indexed holes allowing the extremity to be reproducibly positioned in either a straight or bent position. The base-plate is also provided with attachments to a lock-down bar so that the device can be indexed to the treatment couch tabletop.
The HipFix base-plate is constructed of a carbon fiber/foam composite material for enhanced radiolucency. The HipFix base-plate also features a cutout treatment window, again to enhance radiolucency in the treatment field. The HipFix base-plate is provided with attachments to a lock-down bar so that the device can be indexed to the treatment couch tabletop.
In the T-Form Extremity Immobilizer by Bionix Development Corporation, a thermoformed ABS plastic shell is used instead of a carbon fiber/foam composite material to provide radiolucency and rigidity. The resulting device is lightweight and thin-walled, providing low attenuation for unobstructed passage of the radiation therapy beam. Using a thermoformed plastic design makes a cut-out treatment window unnecessary for the Bionix T-Form Extremity Immobilizer.
In the Multifix device, several small sheets of low-melt thermoplastic are molded to the extremity and secured by locking into one of the indexing holes on the base-plate.

T-Form Extremity Immobilizer- Premarket Notification Submission
The low-melt thermoplastic provides immobilization and isocentric positioning of the target limb.
The HipFix immobilization system utilizes a single sheet of low-melt thermoplastic over the abdomen and pelvis region to provide immobilization and enhance fixed fiducial targeting. A vacuum cushion can be integrated to the HipFix for added comfort and repositioning accuracy.
In similar fashion, the Bionix T-Form Extremity Immobilizer uses a sheet of low-melt thermoplastic to conform to the patient's extremity to provide immobilization and ensure proper positioning for every therapy session. The T-Form Extremity Immobilizer also has a thermoformed depression to facilitate the positioning of optional vacuum cushions as part of the patient immobilization process.
#### Conclusion:
i
The similarity of design, features, radiolucency, and function indicate that the T-Form Extremity Immobilizer from Bionix Development Corporation will perform as well as the legally marketed Multifix and HipFix immobilization devices from Civco Medical Solutions for the intended use of positioning and re-positioning of patients undergoing or receiving a course of external beam radiation therapy for the treatment of cancer and other diseases.

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.
