Indications for Use
The DyeVert™ Contrast Modulation System is intended to be used for the controlled infusion of radiopaque contrast media for angiographic procedures.
Device Story
DyeVert Contrast Modulation System is a sterile, single-use, disposable apparatus for angiographic procedures. It provides a secondary fluid pathway that modifies system resistance during manual injection, diverting excess contrast media into a reservoir chamber away from the patient while maintaining image quality. The device is operated by physicians in a cath lab setting. By reducing total contrast volume delivered to the patient, the device aims to minimize contrast-related risks, such as contrast-induced nephropathy, particularly in patients with chronic kidney disease. The system integrates with standard angiographic syringes and manifolds; it does not require external power or complex software. The healthcare provider uses the device to manage contrast delivery during coronary or peripheral imaging; the output is the modulated delivery of contrast media to the patient's vasculature.
Clinical Evidence
Leveraged prospective, randomized, multi-center clinical trial data (n=147 in treatment group) using the AVERT system. Study population included adults (18+) with chronic kidney disease undergoing therapeutic percutaneous coronary intervention. Primary endpoint: mean reduction of contrast volume. Results showed a 15.4% mean reduction (p=0.0229), corresponding to a 15.0% relative reduction compared to control. Diagnostic procedures showed 20.6% reduction; PCI procedures showed 17.2% reduction. One incident of poor image quality (<1%) reported. No device-related adverse events.
Technological Characteristics
Sterile, single-use, disposable fluid pathway and reservoir chamber. Materials include standard luer lock connections and medical-grade tubing. Operates via passive fluid resistance modulation. Sterilization via Ethylene Oxide (ISO 11135-1:2007). Packaging compliant with ISO 11607. Biocompatibility per ISO 10993-1. No external energy source or software.
Indications for Use
Indicated for controlled infusion and contrast volume reduction of radiopaque contrast media (Iodixanol 270/320 mgI/mL, Iohexol 300/350 mgI/mL, Iopamidol 370 mgI/mL) during angiographic procedures in adult patients (18+ years) undergoing therapeutic percutaneous coronary intervention, including those with chronic kidney disease.

| FDA Center/Branch: | CDRH/Interventional Cardiology Devices Branch (ICDB) |
### Device Description:
The Osprey Medical DyeVert™ Contrast Modulation System provides a second fluid pathway that modifies the overall system resistance as experienced during the physician's manual injection and allows for excess (i.e. contrast that is not needed for diagnostic or therapeutic purposes) contrast media to be diverted into a reservoir and away from the patient while maintaining adequate image quality. Excess contrast is typically a result of refluxed contrast within the patient's vasculature, retrograde to the desired image area. The DyeVert™ System allows for the modulated reduction of contrast media during manual injections in
{4}------------------------------------------------
coronary or peripheral imaging procedures. The DyeVert™ System is a device for physician utilization during efforts to minimize total patient contrast volumes.
The DyeVert™ System consists of a sterile, single-use, fully-disposable apparatus. The source contrast container is connected to the reservoir chamber which has one tube directing contrast (through the manifold) to refill the injection syringe upon aspiration with preference to the diverted contrast volume prior to aspiration from the contrast source.
#### Intended Use:
The DyeVert™ Contrast Modulation System is intended to be used for the controlled infusion of radiopaque contrast media for angiographic procedures.
# Indications for Use:
The DyeVert™ Contrast Modulation System is to be used for the controlled infusion and contrast volume reduction of radiopaque contrast media for angiographic procedures with the following agents: Iodixanol 270 or 320 mgl/mL, Iohexol 300 or 350 mgVmL and Iopamidol 370 mgVmL.

#### Comparison to the Predicate Device:
The DyeVert Contrast Modulation System is substantially equivalent to the previously cleared DyeVert and AVERT Contrast Modulation Systems, K151746 and K151300 respectively, in that they are both designed to control the infusion of radiopaque contrast media for angiographic procedures.
The proposed DyeVert™ System and predicate DyeVert™ System are identical systems with the exception of the labeling modification in accordance with clinical trial data and an additional model number for use with low viscosity contrast as indicated in the labeling.
- . The proposed device consists of the same material and technical characteristics; and
- . No changes have been made to the product performance specifications, sterilization process, manufacturing processes or risk assessment; and
- The intended use and fundamental scientific technology remains unchanged; and ●
- . No new or different questions of safety or effectiveness are raised with the proposed modification.
The performance claim of contrast volume reduction is supported by AVERT System clinical trial data and raises no new or different questions of safety and effectiveness as compared to the predicate. Both the predicate and the Dye Vert System have the identical intended use (i.e. "controlled infusion of dye") and the performance claim does not affect its intended use. The application type, anatomical structure use, patient population and clinical setting remains unchanged. Inherent in the 'control of contrast' is ensuring that sufficient contrast is delivered to maintain adequate opacity during a procedure and simultaneously not creating a situation of excess risk (e.g. excess contrast or radiation exposure); as such, hazard analysis for contrast volume reduction performance and the study adverse event analysis demonstrates no new risk types or increased risk as compared to the predicate.
### Summary of Non-Clinical Testing:
The DyeVert System design consists of standard luer lock connections, tubing, contrast diversion mechanism and a reservoir chamber. Performance specifications of the subject device remains unchanged from the previously cleared version. Bench testing was performed and/or leveraged to support this submission and results demonstrate the DyeVert System materials, design considerations and
{6}------------------------------------------------
manufacturing processes continue to meet product specifications and performance requirements. The following testing was successfully completed and/or leveraged within this submission:
- . Device performance testing for high viscosity contrasts was leveraged and included flow rate, peak pressure, leak testing, contrast diversion, mechanical cycle testing and visual verifications to design specifications for specific contrasts and catheter configurations. Additional device performance testing for use with low viscosity contrasts was completed and included flow rate, peak pressure and contrast diversion. No additional testing was deemed necessary for low viscosity contrast use. All testing passed and demonstrated product performance met all prior established acceptance criteria.
- Sterilization conditions have been validated and leveraged in accordance with ISO 11135-. 1:2007, Sterilization of health care products - Ethylene Oxide Part 1: Requirements for the development, validation, and routine control of a sterilization process for medical devices to provide a Sterility Assurance Level of 10-6. All testing passed.
- . Packaging, shelf life and distribution testing was performed and leveraged. Distribution testing was conducted per ASTM D4169:2009 Standard Practice for Performance Testing of Shipping Containers and Systems. Testing included visual inspection, cycle testing, dye leak test, seal strength test and functional testing. All testing passed and demonstrated product performance met all prior established acceptance criteria. Packaging was deemed to be in compliance with ISO 11607 part 1 and 2:2006 Packaging for terminally sterilized medical devices. Seal strength testing was performed per ASTM F88-09 and seal integrity by dye penetration was performed per ASTM F1886-09. All testing passed.
- . Biocompatibility testing was performed and leveraged in accordance with ISO 10993-1:2009 Biological Evaluation of Medical Devices – Part I: Evaluation and Testing. Testing included cytotoxicity, sensitization, irritation (intracutaneous reactivity), systemic toxicity and hemocompatibility. All testing passed and met prior established acceptance criteria.
- . Simulated Use (Cath Lab) and Design Validation was performed and leveraged for injection pressure, contrast diversion and image analysis testing. Testing included an assessment of the ease of use, system set up and device priming ability (usability). Testing demonstrated no new or different question of safety or effectiveness.
{7}------------------------------------------------
No performance standards have been established under Section 514 of the Food, Drug and Cosmetic Act for angiographic injectors and syringes.
#### Clinical Testing:
Human clinical data was leveraged and analyzed in support of this traditional 510(k) pre-market notification for controlled reduction of contrast volumes. A prospective, randomized, multi-center clinical evaluation was conducted using the Osprey Medical AVERT™ Contrast Modulation System. Leveraging of the clinical data is appropriate due to the high-level similarities of the devices and bench testing the AVERT System represents worse case contrast percentage reduction across the full range of catheter/contrast configurations as compared to the DyeVert System. The study demonstrated a mean difference in contrast volume between the contrast modulation system and control group, achieving a relative and clinically significant contrast volume reduction, while maintaining adequate image quality and with no device related adverse events.
The clinical trial occurred with male and female subjects 18 years and older that were candidates for therapeutic percutaneous coronary intervention procedures with documented chronic kidney disease. The primary effectiveness endpoint was to demonstrate a mean reduction of contrast volume required in the treatment group as compared to the standard of care control group. The data demonstrated a non-normalized distribution of subjects with a mean reduction of 15.4% with a corresponding t-test p value of 0.0229. This corresponds to a 15.0% relative reduction of contrast volume used between the treatment and control groups. Specifically, diagnostic angiographic procedure demonstrated a 20.6% relative reduction and PCI angiographic procedures demonstrated a 17.2% relative reduction. There were no reported device related or unanticipated adverse events. For the sample size of 147 patients (treatment group), there was only one incident recorded as poor image quality related to the treatment device that resulted in the system being "shut off". The result was low prevalence (<1%) and supports the effectiveness of minimizing contrast volume used while maintaining image quality.
#### Statement of Equivalence:
The DyeVert™ Contrast Modulation System has identical intended use, technological characteristics and fundamental scientific technology as the predicate devices. Based on this and data collected in accordance with Osprey Medical Quality System Procedures in compliance with ISO 13485:2003 Medical Devices -Ouality management systems - requirements for regulatory purposes and EN ISO 14791:2012 Risk management for medical devices, the DyeVert System has been shown to be substantially equivalent under 21 CFR Part 807 subpart E.

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.
