Device Story
SureLock™ All-Suture Anchor is a sterile, manually operated, single-procedure device for reattaching soft tissue to bone. It consists of a preloaded UHMWPE suture anchor and a disposable stainless steel/ABS plastic inserter. During surgery (arthroscopic or open), the surgeon drills a hole in the bone, inserts the anchor, and rotates the inserter knob to tension the floating sutures, causing the anchor to expand and deploy within the bone tunnel. The inserter is then removed, leaving the anchor secured. The device stabilizes damaged tissue during the healing period. It is used by orthopedic surgeons in clinical settings. Benefits include secure soft tissue fixation to bone.
Clinical Evidence
Bench testing only. Mechanical pull-out strength testing was performed comparing the SureLock™ All-Suture Anchor to the predicate device. Results showed the ultimate pull-out strength of the subject device was comparable to the predicate.
Technological Characteristics
Materials: UHMWPE (non-absorbable) for anchors and sutures; stainless steel and ABS plastic for inserter. Principle: Mechanical expansion of suture construct via tensioning. Sizes: 1.4mm and 2.2mm. Sterilization: Ethylene oxide. Connectivity: None (manual device).
Indications for Use
Indicated for reattachment of soft tissue (ligaments, tendons, joint capsules) to bone in shoulder, foot/ankle, elbow, hand/wrist, hip, and knee orthopedic procedures. Suitable for arthroscopic or open surgery.
Regulatory Classification
Identification
A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

## DEVICE DESCRIPTION
The SureLock™ All-Suture Anchor is a sterile (using ethylene oxide sterilization method), manually operated, single procedure all suture anchor device for reattachment of soft tissue to bone. The all-suture anchor is preloaded with floating suture and loaded on a disposable inserter. SureLock™ All-Suture Anchor incorporates design features that facilitate suture anchor placement under arthroscopic, open, or limited access conditions in soft tissue to bone reattachment procedures.
The SureLock™ All-Suture Anchor is offered in two different sizes, 1.4mm and 2.2mm. The anchors and floating sutures are made out of non-absorbable Ultra High Molecular Weight Polyethylene (UHMWPE) surgical sutures.
The 1.4mm anchor is formed by passing one end of a length of suture perpendicularly back through itself in alternating directions a number of times. This results in a construct resembling a ladder. The four suture tails are cut and trimmed. A floating suture is passed through the loops in the anchor to form the anchor construct.
The 2.2mm anchor is formed by passing the end of a first length of suture through the core of a second length. Then, one end of the second length is passed through the core of the first length, creating a loop with four suture tails. The loop is twisted alternately a number of times with the floating sutures weaved through each twist to form the anchor construct.
The 1.4mm anchor is pre-loaded with one floating suture and the 2.2mm size is preloaded with two floating sutures.
The following table summarizes the two configurations of the All-suture Anchor device.

The disposable inserter has a working shaft length of 22,2 cm with an outer shaft diameter of 2.0 mm for the 1.4mm SureLock anchor and 2.4mm for the 2.2mm SureLock anchor. The inserter shaft is made out of surgical grade stainless steel and the handle and knob are made out of ABS plastic. The inserter pushes the suture anchor construct into a hole drilled in the bone. The knob on the inserter handle is rotated to apply tension on the floating suture(s) to expand and deploy the anchor in the bone tunnel. The floating suture limbs are then released from the inserter and the inserter is removed.
# NON-CLINICAL TESTING
Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence is included. Mechanical testing (pull-out strength) was performed on the SureLock™ All-Suture Anchor and the predicate device. Testing showed that the SureLock™ All-Suture Anchor ultimate pull-out strength was comparable to that of the predicate device.
# EQUIVALENCE TO MARKETED PRODUCT
Cayenne Medical, Inc. demonstrated that, for the purposes of FDA's regulation of medical devices, the SureLock™ All-Suture Anchor is substantially equivalent in indication and design principles to predicate devices, each of which has been determined by FDA to be substantially equivalent to preamendment devices: ConMed Linvatec Y-Knot™ All-Suture Anchor (K111779), Riverpoint Medical HS Fiber Polyblend nonabsorbable surgical suture (K100006), and Teleflex Medical ForceFiber® sutures
{4}------------------------------------------------
(K040472, K070673, K092533, and K100506). The substantial equivalence of SureLock™ All-Suture Anchor is based on similarities in indications for use, intended use. design features, technology, and materials to the predicate device.
The subject SureLock device has the same intended use as the predicate device, the ConMed Linvatec Y-Knot™. The predicate device has a broad indication for use stated as "to reattach soft tissue, such as ligaments, tendons, or joint capsules to the bone." The subject device is indicated for a subset of the predicate device's indications for use. The subject device has a narrower indication for use than the predicate device. Cayenne Medical tested both predicate and subject devices for the range of the subject device indications using three bone block densities.
This subject device differs from the predicate device, Conmed Linvatec Y-Knot™, in terms of the All-Suture anchor construction, the inserter role during deployment, and the offered sizes.

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.
