Indications for Use
The DRX5000 provides a program of treatments for relief from pain for those patients suffering with low back pain and neck pain. Each treatment consists of a physician prescribed treatment period on the DRX5000 and is designed to provide static, intermittent, and cycling distraction forces to relieve pressures on structures that may be causing low back or neck pain. Conditions that may be treated include neck pain and back pain associated with herniated discs, protruding discs, degenerative disc disease, posterior facet syndrome, and sciatica. It achieves these effects through decompression of intervertebral discs, that is, unloading due to distraction and positioning.
Device Story
DRX5000 is a powered traction device for clinical use by practitioners to treat low back and neck pain. Patient lies on a split-cushion, tilt-type bed; lower cushion slides on low-friction runners to minimize friction during distraction. Pelvic and chest harnesses anchor the patient; traction unit applies distraction forces (0-200 lbs) at angles between 0 and 30 degrees. Device provides static, intermittent, or cycling distraction to decompress intervertebral discs. Practitioner controls treatment via a tower-mounted panel; parameters (tension, time) are monitored via LCD. Safety features include a handheld patient-activated safety switch, emergency stop buttons, and automatic tension release upon electrical interruption or switch activation. Treatment parameters must be manually re-entered if interrupted. Includes integrated DVD player for patient education/comfort. Benefits include pain relief through controlled unloading and positioning of the spine.
Clinical Evidence
No clinical data provided for the DRX5000. The submission relies on the established safety and effectiveness of predicate devices and references clinical trials of similar technology (VAX-D) to support the principle of decompression.
Technological Characteristics
Powered traction equipment; 24V electrical circuit for actuators and control; split-cushion bed with low-friction runners; pelvic/chest harness system; tower-mounted traction unit with pulley system; LCD readout for treatment parameters; handheld patient safety switch; 0-200 lbs distraction range; 0-30 degree pull angle adjustment.

#### Proposed Intended Use
The DRX5000 provides a program of treatments for relief from pain for those patients suffering with low back pain and neck pain. Each treatment consists of a physician prescribed treatment period on the DRX5000 and is designed to provide static, intermittent, and cycling distraction forces to relieve pressures on structures that may be causing low back or neck pain. Conditions that may be treated include neck pain and back pain associated with herniated discs, protruding discs, degenerative disc disease, posterior facet syndrome, and sciatica. It achieves these effects through decompression of intervertebral discs, that is, unloading due to distraction and positioning.
#### Technological and Clinical Application Characteristics
The DRX5000 incorporates various principles and working characteristics of the predicate devices, the 3-D Active Trac (K001712) and the Tru-Trac 401 Traction Device (K844385). The incorporating of the traction device and a flat surface type powered bed, whilst giving a new overall appearance to the apparatus, has not impacted on or changed the safety of effectiveness of the devices. The Tru-Trac 401 has been in use in this country for more than ten years and we have no evidence of a MDR report being filed by the manufacturer nor have we been made aware of any events or conditions effecting the operation of this equipment. Clinical trials carried out by VAX-D (K951622) endorse the

principle of decompression and similar studies using similar technology have reported the same results. (Please see the Appendices).
# Summary of Key Descriptive Elements:
0d3160
page 2 of 3
The key elements to the DRX5000 are as follows:
- 1. The bed is a stand on/stand off tilt type bed that allows the fully clothed patient to step onto a footrest while it is in near vertical position. The bed and patient can then be slowly lowered to the horizontal treatment position using a remote controller hand held by the practitioner.
- 2. The bed is split into two cushions, each slide able in the horizontal plane only on low friction runners and each being able to be locked independently.
- 3. Distraction tensions are applied to the patient via a pelvic harness while the upper body of the patient is anchored to the locked upper cushion via a chest harness. The lower cushion, which is unlocked and on which the patient's lower trunk is rested, is able to slide easily thus reducing almost completely any frictional movement between patient and bed cushion when distraction tensions are applied, this concentrates virtually all the forces to the affected part of the lumbar spine.
- 4. The traction unit is mounted to the foot of the tower and the belt pulley system is attached to a vertical movable platform incorporated into the tower at the foot end of the bed. This enables the distraction tensions to be applied at differing angles to the patient (between 0 and 30 degrees).
- The traction unit is programmed and controlled from a control panel fitted into the 5. tower to give static or intermittent distraction.
- 6. The minimum and maximum distraction settings are 0-200 lbs.
PAGE 2/3
KO23160
- Treatment parameters i.e. tensions and time are continuously monitored and shown 7. by LCD readout at the time of treatment set up and during treatment.
- 8. At the conclusion of treatment time, tension always returns to zero.
- 9. A DVD player, which is incorporated in a separate section of the control panel, and headphones provide comfort and relaxation to the patient and provides and opportunity for patient education via clinical tapes.
- 10. There is instantaneous release of all tensions if the patient pushes the button on the hand held Patient Safety Switch, or the Stop Button, or Emergency Stop on the control panel has been pushed by the practitioner.
- 11. The DRX5000 will not operate if the Patient Safety Switch is not working properly or has not been tested prior to each treatment.
- 12. The treatment cannot be restarted when a patient activates the Patient Safety Switch or the Stop Button has been pushed during treatment unless all treatment parameters are manually re-entered into the controller.

## Summary of Safety Features
KO23160
PAGE 3
The more important safety features of the DRX5000 include:
- 1. The activation of actuators for the bed are via a 24-volt electrical circuit.
- The control circuitry for the distraction unit including the power supply to the Patient 2. Safety Switch is a maximum 24 volts.
- 3. The patient is automatically reclined to the treatment position rather than climbing onto the treatment bed.
- There is instantaneous release of all tensions when the button on the hand held Patient 4. Safety Switch is depressed, the Stop Button is pressed on the control panel, or when electrical current is interrupted. The treatment program cannot be automatically restarted when any of those items in no. "10" have occurred without the full treatment parameters being manually re-entered into the control panel.
- 5. All treatment parameters must be manually entered each time a treatment occurs.
- 6. There is no vertical movement of the traction box only the pulley harnessing traverses vertically thereby stabilizing the traction unit into the foot of the bed ..
- 7. There is a permanent, visible means of indication of the angle of distraction pull.
- 8. There is an audible warning signal when the unit is first turned on, when the treatment is completed, when the Patient Safety Switch is tested and when the Patient Safety Switch is activated during treatment.

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.
