The UroLift System is indicated for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH), including lateral and median lobe hyperplasia, in men 45 years of age or older.
Device Story
The UroLift 2 System is an implantable transprostatic tissue retractor system used to treat BPH-related urinary obstruction. The device is inserted through the penile orifice into the urethra. The clinician uses the delivery handle and implant cartridges to deploy UroLift implants transversely through the prostate. These implants retract the prostatic tissue, displacing the urethra toward the prostatic capsule to maintain an expanded urethral lumen. This reduces fluid obstruction and improves lower urinary tract symptoms. The procedure typically requires 2-6 implants. An optional scope seal allows for anatomical examination without removing the telescope. The device is intended for use by clinicians in a clinical setting. By mechanically holding the approximated inner and outer prostate tissue, the system provides a minimally invasive alternative to traditional surgical interventions, potentially benefiting patients by alleviating urinary symptoms.
Clinical Evidence
Bench testing only. Non-clinical design verification included product performance, compatibility, and deployment testing on devices subjected to worst-case sterilization and transit conditions. Biocompatibility testing was conducted per ISO 10993-1, -5, -10, and -11. Sterilization was validated to a 10^-6 Sterility Assurance Level (SAL) via gamma irradiation. Functional testing confirmed device performance after a 12-month shelf life.
Indicated for treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH), including lateral and median lobe hyperplasia, in men 45 years of age or older. Contraindicated for patients with prostate volume >100 cc, urinary tract infection, urethral conditions preventing delivery system insertion, urinary incontinence due to incompetent sphincter, or current gross hematuria.
Regulatory Classification

### DEVICE DESCRIPTION
The UroLift System is designed to access the prostatic urethra and deliver one UroLift Implant through a lobe of the prostate. The UroLift System is inserted into the urethra through the penile orifice and used to displace the urethra toward the prostatic capsule. The UroLift Implant is then deployed transversely through the prostatic tissue. Multiple implants are deployed in the UroLift System procedure. The implants secure the retracted position of the urethra, thereby maintaining an expanded urethral lumen, reducing fluid obstruction and improving lower urinary tract symptoms (LUTS). This is accomplished by holding the approximated position of the inner (urethral) tissue and the outer (capsular) tissue of the prostate with the UroLift Implant. The procedure typically requires 2-6 implants to retract the obstruction. The UroLift 2 System (UL2), most recently cleared in K173087 under the marketing model number of UL500, is comprised of the UroLift Delivery Handle (single patient use), the UroLift Implant Cartridges (singleuse) and the UroLift Implants (one implant per cartridge). Each Implant Cartridge is preloaded with one UroLift Implant. The Implant Cartridges fit into the Delivery Handle. Each patient procedure will use one dedicated Delivery Handle and the number of Implant Cartridges/implants necessary to perform a typical procedure (estimated 2-6

# COMPARISON WITH THE PREDICATE DEVICE
The UroLift 2 System (formerly UL500) described in this submission is substantially equivalent to the previously cleared generations of the device. The UroLift 2 System was most recently cleared in K173087; previous clearances included K172359, K162345, and K153584. Minor device modifications have been made to the UL2 Delivery System (Delivery Handle and Implant Cartridge) that do not affect the overall safety and effectiveness of the UroLift procedure. No modifications have been made to the UroLift Implant.

The "neoTract" logo is in black and white, while the "Teleflex" logo is in blue. The text "INTERVENTIONAL UROLOGY" is in a smaller, lighter font, providing additional context to the brands.
{5}------------------------------------------------
### COMPARISON WITH THE REFERENCE DEVICE
The UroLift 2 System described in this submission utilizes the cleared UroLift System UL400 for some of the changes to the design of the device including the redesigned distal tip of the proposed device to match the UL400 geometry, as well as the expanded contraindication to increase the prostate size limitation from 80cc to 100cc. The device parameters relevant to the placement of the UroLift implant are identical between the UroLift 2 System and the UroLift System UL400.
### PERFORMANCE TESTING
The design requirements for the UroLift 2 System were reviewed and non-clinical design verification testing was required to assure that the modifications of the proposed device did not impact the safe and effective use of the device. Non-clinical testing included product performance testing, compatibility testing, and deployment testing. The testing was performed on devices which had undergone worst case sterilization and transit testing. The test methods were equivalent to the previously cleared UroLift System, and all acceptance criteria were met.
# BIOCOMPATIBILITY TESTING
The UroLift 2 System has been tested for biocompatibility and passed the relevant tests according to ISO 10993-1: Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process and the FDA guidance "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The modifications addressed in this Special 510(k) submission do not impact the UroLift Implant cleared previously. Parts of the Delivery Device (Delivery Handle and Implant Cartridge) are patient contacting. They are considered externally communicating: tissue, bone, dentin with limited (<24 hour) contact. These components were tested according to ISO 10993-1:2018. Biocompatibility testing was performed on worst case sterilized devices and included, as applicable:
- Cytotoxicity testing per ISO 10993-5:2009 Biological evaluation of medical . devices Part 5: Tests for in vitro cytotoxicity
- Sensitization testing per ISO 10993-10:2010 Biological evaluation of medical . devices Part 10: Tests for irritation and skin sensitization
- Intracutaneous Reactivity testing per ISO 10993-10:2010 - Biological evaluation of medical devices Part 10: Tests for irritation and skin sensitization
- ISO 10993-11:2017: Biological Evaluation of Medical Devices Part 11: Tests ● for systemic toxicity
# STERILIZATION AND SHELF-LIFE TESTING
The UroLift System has been validated to determine the minimum gamma irradiation dose to ensure a 10 ° Sterility Assurance Level (SAL). Due to the modifications of the device, a new sterilization was performed, which included recovery, total bioburden, bacteriostasis/fungistasis, and product sterility. In addition, new dose mapping studies were completed at the sterilization sites.
Device functional testing was performed in a manner equivalent to the predicate to ensure the device functioned as intended after the stated shelf life of 12 months. Additional shelf life studies may be performed to extend the shelf life in the future using equivalent test methods.

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.
