Indications for Use
The intended use for the CycleTrac® Automated Cervical Traction Unit is to provide a primary treatment modality for the management of neck and back pain. Intermittent/static cervical traction results in cervical disk decompression (unloading due to distraction and positioning) which provides relief of pain associated with a variety of conditions involving anatomical dysfunctions of the spine, including protruding or herniated intervertebral discs, degenerative discs and acute facet problems.
Device Story
CycleTrac CT-5000 is an automated cervical traction unit for clinical use. It attaches to standard 6-foot plinths or chiropractic tables. The device uses a non-powered, factory-calibrated gas spring to generate 15-35 lbs of traction force; a motorized actuator compresses the spring to park the device in the 'off' position and releases it to apply traction. The system features a specialized headrest that applies force to the occiput without requiring forehead or chin restraints. A timer controls intermittent or static traction cycles by signaling the actuator. The operator sets treatment time, traction-on time, and traction-off time. The device includes an emergency call cord and automatically powers off at session end. By providing cervical disk decompression, the device aims to relieve pain from spinal conditions. Patients can terminate treatment by lifting their head or using the call cord.
Clinical Evidence
No clinical data provided; bench testing only.

#### Device Description:
The CycleTrac® CT-5000 Automated Cervical Traction Unit is a device intended to apply intermittent or static traction force to the patients' spine. Unlike other traction devices, the CycleTrac® CT-5000 attaches to a Standard 6 Foot Plinth or a 6 Foot Stationary Chiropractic Adjusting Table (not included). When the CycleTrac® CT-5000 is properly attached to the treatment table it is 26.6 inches long and stands 42 inches off the floor. The CycleTrac CT-5000 system has a total weight of 14.5 pounds. The traction force is generated by a non-powered, factory certified gas spring capable of generating up to 35 pounds of load. By adjusting the pivot point of the energized spring along the weight index bar, the traction pull force on the traction pull cord can range from 15 to 35 pounds. The engineering principle behind this change in force is the mechanical advantage created when the energized spring pivot point is adjusted along the

#### 510(k) Summary, cont.
weight index bar. As the pivot point moves further from the traction pull cord intercept, the force required to compress the energized spring decreases. As the energized spring pivot peint gets closer to the traction pull cord intercept, the mechanical advantage lessens and the force required to compress the energized spring increases. When the pivot point is next to the traction pull cord intercept. there is no mechanical advantage and the force required to compress the energized spring is equal to the maximum output of the energized spring. 35 pounds. The force required to compress the energized spring is equal to the push back force of the energized spring on the traction cord, or the traction pull force on the traction pull cord.
The motorized actuator pulls on the extension linkage attached to the weight index bar, which compresses the energized spring, parking it in the traction. To return to the traction ON position, the actuator is extended through the extension linkages attached to the weight index bar allowing the energized spring to freely extend, creating a force on the weight index bar. The force on the weight index bar is transferred to the traction pull cord placing the CT-5000 into the traction on position.
The ON-OFF intermittent cervical traction cycle is controlled by the timer. The traction treatment time, traction ON time, and the traction OFF time are pre-set on the timer. The settings are used by the timer to prompt the actuator to extend and retract, which results in the traction ON / traction OFF intermittent cervical traction cycle. Therefore, the timer and the motorized actuator do not contribute to the traction pull force on the patient. The traction pull force is generated solely by the NON POWERED, factory certified, 35 pound energized spring; the CT-5000 does not require power to generate the traction pull force.
The unique headrest design allows for 100% of the traction force toward the occiput without forehead and chin restrains and eliminates the possibility of Temporomandibular Joint problems. The headrest is made of powder coated aluminum and covered with a comfort pad to keep the patient comfortable.
PT Products, Inc. believes that a comparison of the CycleTrac® CT-5000 Automated Cervical Traction Unit to the predicate devices indicates that there are no significant differences between the devices when comparing the cervical traction mode. Therefore, the CycleTrac® CT-5000 Automated Cervical Traction Unit should not raise any concerns about safety and effectiveness.
#### Intended Use:
The intended use for the CycleTrac® Automated Cervical Traction Unit is to provide a primary treatment modality for the management of neck and back pain. Intermittent/static cervical traction results in cervical disk decompression (unloading due to distraction and positioning) which provides relief of pain associated with a variety of conditions involving anatomical dysfunctions of the spine, including protruding or herniated intervertebral discs, degenerative discs and acute facet problems.
#### CycleTrac® CT-5000 and Predicate Device Similarities:
- . Both systems create a traction pull force.
- Both traction systems use a cord to transmit the traction pull force to a cushioned cradle on which the back of the patient's head rests.
- . Both traction systems use the generated traction pull force to create an axial pull in the occiput region of the patient's head.

- To alert the operator that the patient's traction session is over, both traction systems . beep repeatedly at the conclusion of the traction session.
- Both traction systems automatically power OFF at the conclusion of a traction session. .
#### CycleTrac® CT-5000 and Predicate Device Differences:
- The CT-5000 traction unit requires low voltage DC input to the system (12 volts DC, 3 . amperes). The CT-5000 has a UL medically approved power supply that takes common 120 or 220/240 volt AC power and converts it to the required 12 volts DC, 3 amperes system input. The predicate device (Chattanooga Traction Table TXE-1 and TXF-1, with the Saunders Cervical Headrest) requires a high voltage AC input to the system (120 volt AC or 220/240 volt AC).
- The CT-5000 cervical traction pull force range is 16-36 pounds. The predicate device . pull force range is 0-50 pounds.
- The CT-5000 does not require the use of head straps to remain in the proper position . during traction. The head strap constraint used by the predicate device can produce pressure marks on the patient's forehead and can cause discomfort. In addition, the lack of a head strap on the CT-5000 allows the patient to terminate treatment by simply lifting their head from the headrest assembly, or by using the call cord button to stop the traction therapy.
- The cervical pull force applied by the energized gas spring on the CT-5000 is fixed and t will never be greater than the initial calibrated value of 35 pounds. Because the traction force delivered to the patient is independent of the electric motor, in the event of a motor malfunction, the traction force can never exceed the force of the gas spring. The predicate device is capable of pulling up to 200 pounds, which exceeds the predicate device use range of 0-50 pounds of pull force.

#### 510(k) Summary, cont.
- The CT-5000 emergency call cord is removable, making it replaceable in the case of . malfunction. The predicate device emergency call cord is fixed, making it more difficult to replace.
- . The CT-5000 headrest pad has a calibration scale for the V-Block spacing that can be recorded for each patient to allow for comfort from treatment. The predicate device does not have a calibration setting.

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.
