## 5.3 Substantial Equivalence Claimed to Predicate Device
The ReNew XR Handpiece is substantially equivalent to the RE-NEW LAPAROSCOPIC INSTRUMENTS (K962119), manufactured by MICROLINE PENTAX, INC.
# 5.4 DEVICE DESCRIPTION
{4}------------------------------------------------
#### K201884
The ReNew XR Handpiece is a reusable laparoscopic surgical device used, in combination with legally marketed interchangeable end effectors, such as scissors, and dissectors (all of which are outside of the scope of this submission), to cut, grasp, and dissect various tissues for use in endoscopic, including laparoscopic, surgical procedures where instruments are inserted into the body through a cannula. The ReNew XR Handpiece is pressure tested to ensure that insufflation can be retained during laparoscopic surgery. The ReNew XR Handpiece does not produce energy, but can be connected to any commercially available and legally marketed standard monopolar electrosurgical generator. In combination with such a generator, the ReNew XR Handpiece delivers monopolar electrocautery (electrical) energy to the patient, in which the current is applied through a hand-held active electrode and travels back to the electrosurgical generator through a return electrode attached to the patient, so that the patient is part of the electrical circuit. The ReNew XR Handpiece can be used with a legally-marketed third party electrosurgical high-frequency generator which complies with IEC 60601-1-1 safety and IEC 60601-1-2 electromagnetic compatibility requirements. After use in a procedure, the subject device can be reprocessed via a validated cleaning and steam sterilization procedure as described in the Instructions for Use.
The subject devices are made of six primary components including the Handle Assembly, Turning Knob, Top Cover, Cautery and Flushing Port Assembly, Inner Rod and Outer Tube Assembly.
Variations of the subject devices include varying handle length, presence of a ratcheting mechanism, and single-piece vs. modular (three piece) instruments. Details of the composition of each model number are shown in Table 5.1 below.
The predicate device ReNew Laparoscopic Handpiece [510(k) submission also included end effectors used with the handpiece. These end effectors are not the subject of the current 510(k) and continue to be legally marketed under the existing FDA clearance. Performance testing of the handpiece (see Section 18 (Performance Testing - Bench) and Section 19 (Performance Testing - Animal)) includes use of appropriate end effectors.
There are no medicinal substances associated with the subject devices. There is no use of animal tissue in manufacturing of the subject devices, and they are not made with Natural Rubber Latex, Bisphenol-A, Vinyl (PVC) or Phthalates.

# 5.5 COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
Like the predicate device, the subject device is composed of six primary components including the Handle Assembly, Turning Knob, Top Cover, Cautery and Flushing Port Assembly, Inner Rod and Outer Tube Assembly. The subject device is virtually identical to the predicate in terms of indication for use and operation, and is substantially equivalent in design, technological characteristics, materials, and labeling .
The most significant differences between the predicate device and the subject are the following:
1. The seal between the handpiece tip and the accessory tips has been changed from an elastomer o-ring to a solid overmolded polyvinylidene fluoride bushing to improve service life.
2. The internal metal components of the overmolded variable and fixed handles have been changed to improve insulation to the ratchet and hand grip areas during electrosurgery.
3. The color of the top cover and rotation knob has been changed from black to grey.
Both the subject devices and predicate devices are supplied as non-sterile and intended for cleaning and sterilization by a medical facility before use.
## 5.6 INDICATIONS FOR USE
The ReNew XR Handpiece is indicated for cutting, grasping, dissecting, and coagulating tissue during endoscopic (inclusive of laparoscopic) surgical procedures. Contraindications: None known.
## 5.7 PERFORMANCE DATA
The subject device's performance characteristic testing requirements were assessed in accordance to the requirements set forth in 21 CFR § 820 for Quality System Regulation (OSR), under the FD&C Act, including current Good Manufacturing Practices (cGMP) requirements under this regulation and Microline Surgical, Inc. (hereafter referred to as MSI or Microline) internal procedures documented and applicable within the Corporate Quality System and Product Development procedures.
Bench performance testing was performed as design verification testing and to establish Substantial Equivalence to the predicate device. The functional testing for the subject devices primarily included nonclinical (ex vivo and animal) testing, electrical safety testing, cleaning and sterilization, and biocompatibility testing. The testing establishes that subject device is Substantially Equivalent to the predicate device in fundamental technology, design, or performance. There were no new risks or safety, or effectiveness issues raised in the testing results. The subject devices are supplied as non-sterile and intended for cleaning and sterilization by a medical facility before use.
### Biocompatibility Testing:

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.
