The Medcomp Split Cath® Rg is intended for use in attaining long term vascular access for Hemodialysis and Apheresis in the adult patient.
Device Story
Split Cath® Rg is a long-term, 14 French dual-lumen catheter for hemodialysis and apheresis; provides dedicated arterial/venous access lumens. Catheter features thermo-sensitive polyurethane that softens at body temperature to reduce vessel trauma; venous lumen is 1.0" longer than arterial to prevent recirculation. Device is designed for retrograde insertion; packaged as separate components (lumen, attachable hub, extension assembly) for assembly by clinical personnel post-insertion. Hub assembly includes a stainless steel cannula, compression ring, and hub clamps to ensure secure connection. Used in hospital settings by clinicians. Consistent flows up to 400ml/min. Output is vascular access for extracorporeal blood treatment; facilitates hemodialysis/apheresis procedures, benefiting patients requiring chronic blood access.
Clinical Evidence
Bench testing only. Testing included air leakage, liquid leakage, force at break, recirculation, flow vs. pressure, and priming volume. Additional mechanical hemolysis testing and MRI safety evaluation were performed due to design modifications.
Indicated for long-term vascular access for hemodialysis and apheresis in adult patients. May be inserted percutaneously, primarily in the internal jugular vein, with alternate sites including subclavian and femoral veins.
Regulatory Classification
Identification
A blood access device and accessories is a device intended to provide access to a patient's blood for hemodialysis or other chronic uses. When used in hemodialysis, it is part of an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and provides access to a patient's blood for hemodialysis. The device includes implanted blood access devices, nonimplanted blood access devices, and accessories for both the implanted and nonimplanted blood access devices.(1) The implanted blood access device is a prescription device and consists of various flexible or rigid tubes, such as catheters, or cannulae, which are surgically implanted in appropriate blood vessels, may come through the skin, and are intended to remain in the body for 30 days or more. This generic type of device includes various catheters, shunts, and connectors specifically designed to provide access to blood. Examples include single and double lumen catheters with cuff(s), fully subcutaneous port-catheter systems, and A-V shunt cannulae (with vessel tips). The implanted blood access device may also contain coatings or additives which may provide additional functionality to the device. (2) The nonimplanted blood access device consists of various flexible or rigid tubes, such as catheters, cannulae or hollow needles, which are inserted into appropriate blood vessels or a vascular graft prosthesis (§§ 870.3450 and 870.3460), and are intended to remain in the body for less than 30 days. This generic type of device includes fistula needles, the single needle dialysis set (coaxial flow needle), and the single needle dialysis set (alternating flow needle). (3) Accessories common to either type include the shunt adaptor, cannula clamp, shunt connector, shunt stabilizer, vessel dilator, disconnect forceps, shunt guard, crimp plier, tube plier, crimp ring, joint ring, fistula adaptor, and declotting tray (including contents).

## Device Description:
The Split Cath® Rg Long Term Catheter provides two dedicated (arterial/venous) access lumens. Each lumen is connected through an extension line with female luer connectors. The transition between lumen and extension is housed within a molded hub. To prevent recirculation, the venous end of the lumen is approximately 1.0" longer than the arterial. The catheter is capable of providing consistent flows up to 400ml/min.
The catheter lumen is composed of a soft, thermo-sensitive, polyurethane material that is rigid upon insertion and once it reaches body temperature becomes soft to reduce vessel trauma.
The dialysis extensions are color coded with a white luer, red sleeve, and red clamp for the arterial lumen. The easy identification of the venous lumen, there is a white luer, blue sleeve, and blue clamp.
The proposed device is 14 French in size and comes in the following lumen lengths: 24.28. 32, 36, and 40cm. The catheter is packaged in separate components as they are assembled during retrograde insertion. After the lumen is inserted, it is attached to the Attachable Hub and Extension Assembly using the Lumen Clamp.
## Intended Used:
The Medcomp Split Cath® Rg is intended for use in attaining long term vascular access for Hemodialysis and Apheresis in the adult patient.

## Nonclinical Testing:
Performance Bench Testing:
- 0 Air Leakage
- ହ Liquid Leakage
- 0 Force at Break
- 电 Recirculation
- 国 Flow vs. Pressure
- Priming Volume 0
In addition to the above testing, mechanical hemolysis testing was performed on the proposed device due to the change in blood flow path when compared to the predicate device. Furthermore, the proposed device was evaluated for MRI safety due to the presence of the stainless steel cannula.
#### Technological Characteristics:
The proposed device is intended for retrograde insertion whereas the predicate device is intended for antegrade insertion. To facilitate this retrograde insertion. the proposed device is packaged in a disassembled form to allow for insertion personnel to assemble the hub assembly once the lumen has been inserted and tunneled back to the insertion site.
In order to facilitate proper connection between the lumen and hub assembly. the hub assembly is outfitted with a stainless steel cannula that is not present in the predicate device. The sure fit of this cannula to lumen, followed by application of the compression ring and hub clamps, is essential to device integrity following the insertion and assembly procedure.
Once inserted and assembled, the principles of operation with regard to hemodialysis are the same as the predicate devices. There are no new questions raised regarding the safety or effectiveness of the device.
#### Summary of Substantial Equivalence:
In this submission, testing is provided to address the difference in technological characteristics between the proposed and predicate devices. Nonclinical testing and discussion of previously submitted information on the predicate devices establish that there are no new issues of safety or effectiveness for the proposed device.
The proposed device meets the performance criteria of design verification as specified by ISO standards, guidance documents and test protocols. The proposed device has the same intended use, operation and function as the predicates. There are no differences that raise new issues of safety and effectiveness. The proposed device is substantially equivalent to the legally marketed predicate devices.

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.
