The Evolution® RL Controlled-Rotation Dilator Sheath Set and the Evolution® Shortie RL Controlled-Rotation Dilator Sheath Set are intended for use in patients requiring the percutaneous dilation of tissue surrounding cardiac leads, indwelling catheters and foreign objects.
Device Story
Device consists of two coaxial sheaths connected to a handle with a trigger mechanism; inner sheath rotates (uni- or bi-rotational) to dilate binding tissue anchoring cardiac leads or catheters to vascular/cardiac walls. Outer sheath stabilizes cardiac wall at lead/catheter tip attachment site to facilitate detachment and removal via counter-traction. Used in clinical settings by physicians during lead or catheter extraction procedures. Mechanical rotation assists in freeing foreign objects or indwelling devices from surrounding tissue. Benefits include improved ability to safely remove anchored cardiac leads or catheters.
Clinical Evidence
Bench testing only. Testing included fatigue and binding, handle cycling (2000 cycles), buckling, pull force (20 lbs), reciprocating action (1000 cycles), continuous rotation (1000 cycles), peel force, biocompatibility (ISO 10993-1:2009), and sterility. All predetermined acceptance criteria were met.
Technological Characteristics
Coaxial sheath system with mechanical handle-actuated rotation. Materials evaluated per ISO 10993-1:2009 for limited contact (≤ 24 hours) with circulating blood. Sterilized via ethylene oxide. Available in 9, 11, and 13 French diameters. Working lengths of 40.6 cm (RL) and 13.6 cm (Shortie).
Indications for Use
Indicated for patients requiring percutaneous dilation of tissue surrounding cardiac leads, indwelling catheters, and foreign objects.
Regulatory Classification
Identification
A vessel dilator for percutaneous catheterization is a device which is placed over the guide wire to enlarge the opening in the vessel, and which is then removed before sliding the catheter over the guide wire.

#### Device Description:
The Evolution® RL Controlled-Rotation Dilator Sheath Set is constructed of two coaxial sheaths connected to a handle capable of mechanically rotating the inner sheath. In use, the coaxial sheaths are advanced over an indwelling catheter or cardiac lead. The inner sheath (available in 9. 11. and 13 French diameters) is designed to rotate in either a uni-rotational or bi-rotational manner by pulling the trigger in the handle assembly. As the inner sheath is advanced, the rotation of the sheath assists in dilation of any binding tissue which may be anchoring the catheter or lead to the inner vascular or inner cardiac wall. The outer coaxial sheath can be used to stabilize the cardiac wall at the point of lead/catheter tip attachment to allow for detachment and removal (counter traction technique). The device has a working length of 40.6 centimeters.

#### Comparison to Predicates:
The Evolution® RL Controlled-Rotation Dilator Sheath Set and the Evolution® Shortie RL Controlled-Rotation Dilator Sheath Set are substantially equivalent to the predicate device, the Evolution® Mechanical Dilator Sheath Set (K061000), in that these devices have similar designs, methods of construction and operation, and indications for use.
#### Technological Characteristics:
ﻟﺴﻴﺮ,
The following tests have been conducted to ensure reliable design and performance under the specified design requirements. These tests include:
1. Fatigue and Binding Testing - Testing was performed with the requirement that the sheaths should not kink, buckle, or fracture, and both the sheaths and the handle should remain functional after 50 cycles of flexing no less than 90° in opposite directions. The results showed that these predetermined acceptance criteria were met. The predetermined acceptance criteria established for this test corresponded to the acceptance criteria utilized for the predicate device cleared under K061000. with the exception of requiring 10 additional cycles of flexing as compared to the acceptance criteria for the predicate.
2. Handle Cycling Testing - Testing was performed with the requirement that the sheaths should not kink, buckle, or fracture, and both the sheaths and the handle should remain functional after being subjected to rotation via 2000 pulls of the handle trigger while fixed in a curved position to a radius of 3.5 inches. The results showed that these predetermined acceptance criteria were met. The predetermined acceptance criteria established for this test corresponded to the acceptance criteria utilized for the predicate device cleared under K061000.
3. Buckling Testing - Testing was performed with the requirement that the sheaths should not kink, buckle, or fracture should remain functional after being subjected to rotation via 2000 pulls of the handle trigger while fixed in a curved position to a radius of 3.5 inches. The results showed that these predetermined acceptance criterion was met. The predetermined acceptance criteria established for this test corresponded to the acceptance criteria utilized for the predicate device cleared under K061000.
4. Pull Testing/Sheath Pull Assembly Testing - Testing was performed with the requirement that each joint in the devices should withstand a minimum of 20 pounds of pull force, after being subjected to the previous tests. The results showed that these predetermined acceptance criterion
{3}------------------------------------------------

was met. The predetermined acceptance criteria established for this test corresponded to the acceptance criteria utilized for the predicate device cleared under K061000.
5. Testing of Reciprocating Action - Testing was performed with the requirement that the rotational mechanism should remain functional through 1000 cycles of alternating clockwise and counterclockwise rotation. The results showed that these predetermined acceptance criterion was met.
6. Testing of Continuous Clockwise Rotation - Testing was performed with the requirement that the rotational mechanism should remain functional through 1000 cycles of clockwise rotation. The results showed that these predetermined acceptance criteria were met.
7. Testing of Continuous Counterclockwise Rotation - Testing was performed with the requirement that the rotational mechanism should remain functional through 1000 cycles of counterclockwise rotation. Thus, the predetermined acceptance criteria were met.
8. Peel Force Testing - Testing shows that the peel-away outer sheath of the Evolution Shortie RL Controlled-Rotation Dilator Sheath Set should require a peel force of less than 8 pounds. Thus, the predetermined acceptance criteria were met.
9. Biocompatibility Testing - Per ISO 10993-1:2009. the proposed devices were classified as external communicating devices in contact with circulating blood for a limited (≤ 24 hours) duration. The following tests were completed and the biocompatibility was deemed acceptable: Cytotoxicity, Sensitization, and Irritation/Intracutaneous Reactivity, Systemic Toxicity, Hemolysis, Partial Thromboplastin Time, C3a Completement Activation, SC5b-9 Complement Activation, and Pyrogenicity.
10. Sterility Testing - The proposed devices were evaluated for bioburden levels, endotoxin levels, and ethylene oxide and ethylene chlorohydrin residuals. Their sterility was deemed acceptable.
## Conclusion:
The results of these tests support a conclusion that the Evolution® RL Controlled-Rotation Dilator Sheath Set and the Evolution® Shortie RL Controlled-Rotation Dilator Sheath Set met the design input requirements based on the intended use and support the conclusion that these

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.
