Indications for Use
UroLift® System is intended for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH) in men 50 years of age or older.
Device Story
The UroLift System UL500 is a mechanical surgical device used by urologists to treat BPH. It consists of a reusable delivery handle and single-use implant cartridges containing permanent implants. During a transurethral procedure, the physician inserts the device through the penile orifice into the prostatic urethra. The device displaces the obstructive prostatic tissue laterally toward the prostatic capsule. The system then deploys a permanent implant transversely through the prostate tissue, anchoring the urethral tissue to the capsule. This retraction maintains an expanded urethral lumen, reducing obstruction and improving lower urinary tract symptoms (LUTS). The procedure is performed in a clinical setting. The device provides a minimally invasive alternative to traditional surgical resection by mechanically holding the prostate lobes open.
Clinical Evidence
No clinical data provided. Evidence consists of bench testing, including design verification, transit testing, joint strength testing, and packaging/labeling integrity. Biocompatibility testing was conducted per ISO 10993. Design validation was performed using a cadaveric model to confirm the device met customer requirements.
Technological Characteristics
Mechanical transprostatic tissue retractor system. Components: reusable delivery handle, single-use implant cartridges, and permanent implants. Biocompatibility per ISO 10993. Sterilization validated for handle and cartridges. Shelf-life testing performed for sterility and functionality. No software or electronic components.
Indications for Use
Indicated for men 50+ years of age with urinary outflow obstruction symptoms secondary to benign prostatic hyperplasia (BPH).
Regulatory Classification
Identification
An implantable transprostatic tissue retractor system is a prescription use device that consists of a delivery device and implant.

## INTENDED USE
The UroLift System is intended for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH) in men 50 years of age or older.
## PREDICATE DEVICE
The predicate device is the UroLift System UL400, DEN 130023 and K133281, which were cleared to market by this Center on 13 September 2013 and 13 December 2013, respectively.
## DEVICE DESCRIPTION
The UroLift® System UL500 is comprised of the UroLift® Delivery Handle (single patient reusable), the UroLift® Implant Cartridges (single-use) and the UroLift® Implants (one implant per cartridge). Each patient procedure will use one dedicated sterile handle and the number of cartridges/implants necessary to perform a successful procedure (estimated 2-6 implants). The cartridges fit into the delivery handle.
{4}------------------------------------------------
The UroLift Delivery Handles (UL500-H) and UroLift Implant Cartridges (UL500-C) will be sold separately. The UroLift System UL500 Delivery Handles will be sold two per carton and the UroLift System UL500 Implant Cartridges will be sold eight per carton. Both cartons will contain the same UroLift System UL500 Instructions for Use (IFU).
The UroLift System UL500 is designed to access the prostatic urethra and deliver one UroLiff Implant through a lateral 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. The implants secure the retracted position of the urethra thereby maintaining an expanded urethral lumen, reducing fluid obstruction and improving 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.
## COMPARISON WITH THE PREDICATE DEVICE
The UroLift System UL500 described in this submission is substantially equivalent to the predicate device in that they share the same intended use and employ the same technology characteristics. The implant is identical to the predicate device.
## PERFORMANCE TESTING
Bench testing, including design verification and transit testing, performed for the NeoTract UroLift System UL500 demonstrated that the device meets the same performance requirements as the predicate device. Testing included the verification of packaging and labeling integrity as well as bench verification testing of the devices, and joint strength testing. All acceptance criteria were met. Design validation was performed in a cadaveric model and demonstrated that the UroLift System UL500 met the customer requirements.
## BIOCOMPATIBILITY TESTING
Testing was conducted in accordance with ISO 10993 to assure the elements of the device that are patient contacting are biocompatible.
## STERILIZATION AND SHELF-LIFE TESTING
Sterility has been demonstrated for the UroLift System UL500 Delivery Handle and Implant Cartridge. Shelf-life testing was performed and supports the continued sterility of the device, packaging integrity and device functionality over the shelf-life of the device.
#### CONCLUSION
The testing demonstrated the NeoTract UroLift System UL500 is as safe and effective, has the same intended use, technological characteristics and principles of operation as the predicate device. Therefore, the NeoTract UroLift System UL500 is substantially equivalent to the predicate device.
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.
