Indications for Use
LTM-Perforated Surgical Mesh is intended for use as a soft tissue patch to reinforce soft tissue where weakness exists and for the surgical repair of damaged or ruptured soft tissue membranes. Indications for use include the repair of hernias and/ or body wall defects which require the use of reinforcing or bridging material to obtain the desired surgical outcome. LTM-Perforated Surgical Mesh is intended for single patient one-time use only.
Device Story
LTM-Perforated Surgical Mesh is a porcine-derived acellular dermal matrix used as a soft tissue patch for hernia and body wall defect repair. The device is processed in a phosphate-buffered aqueous solution with matrix stabilizers and provided in specific geometric configurations. It is a single-use, terminally sterilized sheet. The primary design modification from the predicate is the addition of a pre-defined pattern of perforations, created during the final die-cutting stage, to improve handling or integration while maintaining mechanical integrity. Used in healthcare facilities by surgeons, the mesh provides structural reinforcement to weakened or damaged tissue. The device is implanted to support the surgical repair, facilitating the desired clinical outcome for soft tissue reconstruction.
Clinical Evidence
No clinical testing was performed. Substantial equivalence is supported by bench testing comparing the subject device to the predicate. Bench evaluations included mesh thickness, tensile strength, device stiffness, suture pull-out strength, tear resistance (ASTM D5735-95), and burst strength (ASTM D6797-07). Results demonstrate that the perforated mesh maintains mechanical properties equivalent to the non-perforated predicate.
Technological Characteristics
Material: Porcine acellular dermal matrix. Preservation: Phosphate-buffered aqueous solution with matrix stabilizers. Form factor: Terminally sterilized sheet with pre-defined perforation pattern. Sterilization: Electron beam irradiation. Mechanical testing standards: ASTM D5735-95 (tear resistance), ASTM D6797-07 (burst strength).
Indications for Use

#### DEVICE DESCRIPTION 4.
LTM-Perforated Surgical Mesh is a surgical mesh that is derived from porcine dermis and then processed and preserved in a patented phosphate buffered aqueous solution containing matrix stabilizers. The device is designed to perform as a surgical mesh for soft tissue repair. The device consists of a terminally sterilized sheet of processed porcine dermal matrix provided in prescribed geometric configurations and thicknesses. The device is packaged in a double pouch configuration, and is sterilized via electron beam irradiation. The device is considered a single use device which is to be used in a healthcare facility or hospital.
The subject device shares the same underlying scientific design as a porcine derived acellular dermal matrix, and has the same Intended Use, Indications for Use, and principles of operation as the cleared predicate device, LTM-Surgical Mesh (K070560). This 510(k) premarket notification describes a new design feature of the subject device, which introduces a pre-defined pattern of perforations throughout the tissue matrix.
### 5. INDICATIONS FOR USE
LTM-Perforated Surgical Mesh is intended for use as a soft tissue patch to reinforce soft tissue where weakness exists and for the surgical repair of damaged or ruptured soft tissue membranes. Indications for use include the repair of hernias and /or body wall defects which require the use of reinforcing or bridging material to obtain the desired surgical outcome.
LTM-Perforated Surgical Mesh is intended for single patient one-time use only.
### 6. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The subject device, LTM-Perforated Surgical Mesh, and the predicate device, LTM-Surgical Mesh (K070560), are both derived from porcine dermis and then processed and preserved in a patented phosphate buffered aqueous solution containing matrix stabilizers. The material type for both devices can be described as a porcine acelluar dermal matrix. Both devices consist of a terminally sterilized sheet of the processed porcine dermal matrix provided in prescribed geometric configurations and thicknesses. Both are packaged in a double pouch configuration and sterilized via electron beam irradiation.
The subject device, LTM-Perforated, and the predicate device, LTM-Surgical Mesh (K070560) share the same underlying scientific design as a porcine derived acellular dermal matrix, and have the same Intended Use, Indications for Use, and principles of operation. The predicate introduces a new design feature, a pre-defined pattern of perforations in the tissue matrix. The spacing and size of the perforations were specifically designed to maintain mechanical properties and meet the same established performance specifications as the predicate device, LTM-Surgical Mesh. The subject device utilizes the existing manufacturing processes of the predicate LTM-Surgical Mesh. Perforations are added to the tissue during the final die cutting stage at the time the device is cut to its final dimensions.
{5}------------------------------------------------
#### 7. PERFORMANCE
The predicate device, LTM-Surgical Mesh (K070560) has undergone appropriate biocompatibility testing, animal testing, and viral inactivation testing. The data demonstrates that the device is biocompatible and that the manufacturing process is capable of viral inactivation. The subject device, LTM- Perforated Surgical Mesh and the predicate device, LTM-Surgical Mesh (K070560) utilize the same raw materials (porcine dermis), processing components/solutions and manufacturing processes, and are identical except for the presence of perforations. Therefore, no further biocompatibility testing, animal testing, or viral inactivation testing was performed given that the presence of perforations does not change the biochemical or material properties of the surgical mesh.
# Bench Testing:
Bench testing was performed on the subject LTM-Perforated Surgical Mesh device to support substantial equivalence. Testing and/or evaluations included relevant elements of the FDA "Guidance for the Preparation of a Premarket Notification for a Surgical Mesh'" issued March 2, 1999. Table I includes the applicable product characterization criteria used to demonstrate substantial equivalence.
| Table 1: Substantial Equivalence Criteria | |
|-------------------------------------------|---------------------|
| Bench Testing /Evaluation | Applicable Standard |
| Mesh Thickness | N/A |
| Tensile Strength | N/A |
| Device Stiffness | N/A |
| Suture Pull-Out Strength | N/A |
| Tear Resistance | ASTM D5735-95 |
| Burst Strength | ASTM D6797-07 |
Performance data demonstrates that LTM-Perforated maintains similar mechanical properties and meets the established specifications as the predicate device. In addition, the LTM-Perforated Surgical Mesh shares the technological characteristics of perforations with other legally marketed reference devices. This new technological characteristic does not affect safety and efficacy of the device or raise new questions of safety or efficacy. LTM-Perforated Surgical Mesh meets the requirements to perform its intended use as a soft tissue patch and is substantially equivalent to the predicate device, LTM-Surgical Mesh (K070560).
# Clinical Testing:
No clinical testing was included in this submission.
#### 8. CONCLUSIONS
The subject device, LTM-Perforated Surgical Mesh, meets the requirements to perform its intended use as a soft tissue patch and is substantially equivalent to the legally marketed predicate device, LTM-Surgical Mesh (K070560).
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.
